Internal Storage -> External SDCard = File Corruption? - Sprint HTC EVO 4G LTE

Ok for real, I know I'm not crazy. I've tested my SDcard on my tablet by checking md5 sums of rom zips from both internal storage and external sdcard and they match perfectly, everytime.
BUT when I transfer rom zips from my internal storage of the EVOLTE to the same external sdcard, I GET MISMATCHED MD5 SUMS EVERYTIME. Not only that, When I download rom zips to my external, I get the same problem.
Is this a common problem? (afaik it's not)
Is this a problem with my Evo or my sdcard? I don't think it's the latter since i tested it on my tablet with no issues.
Any help would be great! thanks in advance!
EDIT: I should add that when transferring from External to Internal, I do not get the MD5 mismatch

You might be right. I moved some of my pictures and they became corrupted when moved from internal to external
sent from my EVO LTE

You guys should try formatting the card from the phone, that sometimes fixes the situation. Also, what kind of SD Card you have?
Warning: Please perform a backup of the card before doing so, you will loose all info on the card when formatting.

The worst part is downloading rom zips straight to microsd. The MD5's NEVER match. this was why i was having so much trouble with getting Charmeleon rom to boot!..
Can anyone else replicate this issue?

Ive reformatted both in my PC (full format and quick format) as well as on my phone, with two different SD cards. And corruption occurs on both cards.
I'm pretty sure it's not my sd cards. Like i said, I've transferred large rom zips from my internal storage of my Transformer tab to the two sdcards and in both instances, there was no corruption (md5's check). Apply the same tests to both cards on my LTE, however, resulted in mismatched md5's.
EDIT: I've also tried this test on Stock as well as custom roms. with stock kernel

Bump.
Has anyone else had trouble with file corruption? If not then I'll have to get a replacement. Which I would hate to do... Not for me per se, for sprint.

so finally bit the bullet and got a replacement. Rechecked files transferred and it turns out that it WAS my phone that was corrupting files that were transferred to the sd card.
So i guess i just had a faulty one =]

[Q] Cant Write to SD Card

Been using this card in my phone for no problem since day one, now all of a sudden whenever I try and copy an mp3 from my PC in mass storage mode I get the "Error 0x80070057: The parameter is incorrect" and cant copy the file. Did some searching and people said formatting the card fixes that problem so I did so but that didnt fix the problem for me. Whats really weird is the fact that it only happens when trying to write mp3 files. I can move pictures and other files over with no problem. Any ideas on fixing this would be greatly appreciated.
I am having the same problem. I just flashed TW v5 and also the jk6 modem. I can copy to internal sd but the external I cannot copy any thing to. I get the same error message as you are getting. I have tried the two fixes that had been posted but neither one changed the situation. This has been an issue for me since i first flashed a Bionix rom. At first before this last rom the drives were reversed or seen as reversed which caused problems with recovery. I have no idea what is causing this or what the remedy is. Any and all help is warmly received and greatly appreciated.
My computer doesn't even see my phone
It would seem to have something to do with the phone itself. When I pop the card into a card reader it writes just fine
Fix found. Flashed this and all is well.
http://forum.xda-developers.com/showthread.php?t=846384
I tried the mounting fix and it did show the drives in the proper sequence but I still get the parameter error and am unable to write or copy to external sd card. Does not make any difference whether it is mp3 or zip files nothing will copy over. I am in Obsidian V5 and I really like the rom and I tried jk6 stock but had the same result. Any and all help and info is greatly appreciated and welcomed.
Edit: I do have one question if I format the external sd will that wipe everything off of it? ( I would imagine it would) Perhaps that is why I still cannot copy to external sd. I have never reformatted an sd card and I would really really be grateful if someone could give me guidance or directions on how to proceed with this.
flashing to the leaked stock jk6 fixes this for me. One guy suggested change usb setting to mediainstead of mass storage in order for it to work. Gl.

Remove the card from your phone and put it into a USB card reader on your PC/Mac. From there you should be able to copy all the data off of it. After backing up everything on the card either format the card in your phone or from your computer. See if that helps. I've run this fix on 3 different ROMs and it worked every time.

[Q] New sd card issues

Bought a 16gb Kingston class 4 sd card for my 3D, problem is after I moved all items over to the new card. I moved over some rom files to flash and when looking at the contents of the card they are not there. Neither are the back up files of my TWRP backups. Titanium backup files aren't there either.
When I run Titanium again thenfiles are there, but after a reboot they are gone again????
Any ideas?
Also getting issues when downloading Swiftkey X language packs. Get an error that says "unable to load language packs."
Please use the Q&A Forum for questions Thanks

Where did u get the micro sd card?
Sent from my super powered red wings evo 3d
I just bought a class 4 SanDisk 16gb card last night and so far haven't had any problems. I took the card out the phone, put it in the laptop and copied everything to a new folder then copied it all to the new card. My nand backup was all there cus I just flashed it back and everything restored. But i haven't done much else.
Sent from my double barrel Shooter. BANG!
Think I fixed it. Ended up wiping the card and wiping the phone also. I am a ROM Flashing fanatic so I needed more card capacity.
So I thought my sd card woes were gone. But, downloaded a few ROM's to try out on my PC. Transferred the files over to the phone via USB cable. While still connected to the phone I created a new folder and placed the ROM's into it to keep them more organized.
I went this morning to flash a new ROM as the one I was trying had an issue I did not like and now the ROM folder is gone. the LOST.DIR is at approx 1.3GB which to me would mean that the folder was moved there for some reason.
Also, when I try to restore my backup, the restore begins, but the phone then just goes black. Then have to pull battery. I am on TWRP Recovery.
Any ideas? I am assuming it is the new 16GB card I got, but any scans I do on it report no issues. Never had an issue with an sd card before.

unfortunately, i've only had two issues with sdcards and they have been far and few between, but devasting when they occur.
the most recognizable behavior of a poor or failing sdcard that i've experienced are missing or inconsistent (names changed, locations moved, etc) files. personally, i would return the sdcard as it definitely appears to be defective and ask for either an exchange or money back.
sorry that isnt a very good solution, but for a brand new sdcard out of the box to keep losing files, moving them, etc. that definitely would be a red flag in my opinion. hope that helps!
Sounds like a bad SD card to me, had the same issues. I guess thats what happends when you buy sd cards off craigslist. I returned the failing SD card got my money back then headed straight to Frys got myself a PNY 32gb SD card and problem solved

[MOD] Swap your usb storage with external SD!

Tired of that small 5gb usb storage? Here is my hack to swap your external SD card with the USB storage!
This is usefull especially if you use GPS apps that download maps or games that download big data files! I got the idea and studied several hacks for the galaxy 1900 so partial credit goes to whoever made those hacks.
DISCLAIMER : I have only tested this on the 4.0 U.S version running 2.3.5 and am not responsible for a brick (although it seems impossible to brick your phone while messing with this file).
So basically start by going to /system/etc using root explorer or similar (yes, you need root). Once there backup the vold.fstab file to somewhere ON ROOT (I put it in /data/app/)! This is important so you can access it if you need to restore it (also make sure root explorer is installed on device memory, not SD card). Now take my modified vold.fstab and replace the original in /system/etc, then change the permissions to rw-r--r-- (long click the file, then select permissions) . If all goes right after you reboot your device, USB storage should now be your SD card and vise versa! Be aware any apps on your USB storage will now have to be transfered using a PC, move the .android_secure folder to your SD card. Hope it works!
EDIT: here is a modified version for the yp-g70, all credit goes to rjsmith2007 for making and testing this!
Won't Maps pull data from the Ext SD anyway? All my music is on ext SD and players have no problem finding it; I would think maps would be the same. It's really like a 5gb and 16 gb (in my case) partition (isn't it?).
I'm looking for a reason to root, SD card/space is not one of them. My battery only charging to 90% is though, need to recalibrate (since it's never hit 100%)

I am referring to when you download maps with an app like sygic;
it saves it to the /sdcard/ directory instead of the /sdcard/external_ed/. Also gameloft games do the same and can use up your room pretty fast. I find this pretty useful myself, since I have a 32gb sd card, but just wanted to post it so if anyone does ever need it, it's here for them.

I just tried it with my Galaxy S Wifi 5.0. The mapping of the internal sd to the external_sd folder fails, but it works for mapping my external sd to the sdcard folder.
Edit: I took a look at the original and made a modification to yours to work with the YP-G70 model (the 5 inch one). Just copy the file from within the zip folder to your /system/etc folder.

Can't I just copy all of the data from my internal sd card onto my computer, remove the internal sd card, copy those files onto a larger sd card and put the larger sd card back into the galaxy player? Im sorry if this Queston has been asked before, or if it sounds stupid, but I can't find the answer to this Queston anywhere! Thanks in advance!

Hi,
There's still a bit of confusion with respect to terminology, I think (including myself).
I *think* that when the SGP5 displays "internal sd card", it's only part of the "internal 8GB memory". That "internal 8GB memory" is probably, I guess, something like an SDCARD or flash memory module that's soldered to the mainboard, and with Android, I think that it's split into a couple of areas.
Here's my "guess" of how things are arranged, using the terminology from Settings==>SD card and device storage:
"System storage": Part of the 8gb internal memory, e.g., includes /system, etc.
[1.65GB, in my SGP5]
"USB Storage" = "internal sd card" = /sdcard: The rest of the 8gb internal memory.
[5.01GB, in my SGP5]
"SD Card": The external microSD card, if you have one plugged in. Appears at /sdcard/external_sd.
[29.81GB, in my SGP5, where I have a 32GB microSD card plugged in.]
That System storage + USB Storage totals 1.65+5.01 GB, or 6.66GB. I guess the remainder of the 8GB is for bootloader, etc.?
Jim
Looks about right. Task Manger has them labeled like you list them, except there is a "Personal data" partition. It's 133mb on my 5.0. Maybe email and contacts?
I'm guess apps get installed on "System Storage", plenty of room there without having to move stuff to USB or Ext. I pretty much just use my ext card for media and pictures.
For some reason this caused issues with my Market connecting to the internet, any idea why? Anyone else experience issues with this modification?
Hmm, no no one has mentioned that problem, and I have been using this for months - no problem. Sorry if it did that, have you tried restoring the original? Also, an update to the instructions is to change the permissions to rw-r-r. I didn't notice anything wrong without changing the permissions, but you never know.

Pretty close.
https://github.com/Entropy512/initramfs_yp-g70/blob/master/misc/recovery.fstab is the Player 5.0 partition table.
As you can see, nearly everything is on partitions of mmcblk0 - on the Player 5.0, this is eMMC (embedded MMC) storage. The total size of mmcblk0 is 8GB
The partitions here include (but are not limited to):
p10 - EFS - this contains device-specific config data, on phones that includes IMEI, on our device it's probably Bluetooth and WiFi MAC addresses
p11 - Kernel
p12 - Recovery (on some devices, recovery is a separate kernel partition - Samsungs have this partition set aside even though most of their devices don't actually use it. You can put anything you want on p12 and it won't do anything usually. For us, recovery is part of the kernel initramfs on p11)
p13 - /system - This is where the system firmware, often called the "ROM" sits. A number of people are trying to fight the "ROM" terminology, since it's not really true - flash isn't read-only, thus it isn't the "ROM" any more
p14 - In the linked file it's /datadata, but the device actually mounts it as /dbdata - various SQL databases for apps live here
p15 - /cache - a cache partition separate from data. Files stored here are intended to be safely wipable/deletable
p16 - /data - Various user data. Your apps live here unless you've moved them to SD. Most system settings are here too. ICS merges this partition with the internal SD so they are one and the same
p17 - /emmc in recovery and, if someone ever has the time to port it, CM7, /sdcard in Samsung factory firmwares. This is the "internal SD card".
There are a few other partitions that are not touched by recovery that exist, such as the LFS partition and the bootloader partitions. These are all small.
mmcblk1 is the external SD. Usually only one partition, which is /sdcard in recovery/CM7 and /sdcard/external_sd in Samsung factory firmwares
On the 4.0, I believe it uses Samsung's older NAND flash technology and not eMMC, so the partitions on internal storage appear as stlN/bmlN
i think i did something disaster...
i am using Samsung Galaxy W. I did follow your above instruction. The problem is after restarting my phone, I go to setting>storage and it shows total space and available space for SD card and USB storage is UNAVAILABLE. What is available is only Device Memorry which is 1.03GB.
Thinking that your vold.fstab is not compatible with my Samsung Galaxy W, I replace it with the original vold.fstab that I backed up earlier. However this does not solve the problem.
Then what I did is I tried to reset the phone to its original factory setting (Setting>Privacy>Factory Data Reset..),. Unfortunately the same problem still persist. And i think this is silly and catastrophic step since i loss my original vold.fstab which is stored in the internal memory.
Any of you can help me?
Many thanks to all of you
Well, did you change the permissions on your backup back to rw-r--r--? And yes, this mod should only be used for the device intended for. Are you sure that you replaced the modified vold.fstab with the original one? Did it give you an warning about overriding (it should have)? Are you sure you used your backup and not accidentally mine? What program did you use to copy?
Hmm stupid question, but how do you replace the existing file? I am using root explorer an it says it is read-only when I try to paste it in there.
Edit... Never mind... I didn't have it mounted correctly.
I have tried this multiple times, but every time I reboot it says "USB storage damaged, may need reformatting." So I press reformat, and it's done in like 1 sec and the problem still persists.
Any ideas?
Hmm, odd. I know you have the same version player as me, are you running 2.3.5 or 2.3.6, maybe that could affect it? Did you try before you did a lot of modifications to your device? What type of SD card you got, I use a 32gb class sandisk. I don't think that would matter, but you never know. I recall getting that error when I was working on the mod, but I got it fixed before I released it. Weird.
Oh yeah, what do you have your sd card formatted as? I use FAT32, not sure if that could affect it. May want to try reformatting the card on a PC, then try.
I have a 8gb kingston micro sd card, and I'm running 2.3.5. I had this problem a long time ago too when I was still on stock. Maybe it's my sd card. I will reformat it and try again, and if it doesn't work I will try a different sd card.

[Q] MicroSD card appears almost empty

HI
I took the 32gb memory card out of my old HTC Desire HD and put it into my new S3.
Very strange because although the directory structure appears, the file explorer reports that every directory is empty - which they aren't.
The storage statistics correctly tells me that the memory card is almost full - so why won't it read the files?
I think that's the same thing as what happened to me today. No idea why it happened, but the SD contents showed up correctly after rebooting my phone.
Thanks.
Comforting to know that it isn't only me. However I rebooted the phone but no change.
Sounds like a formatting problem. You might have to copy the data off to a computer using a card reader or the old phone then reformat the card using the gs3 before putting your data back on the card.
Sent from my LG-P920 using xda premium
Yes, I think that must be the explanation. What a nuisance.
I'll try it and report back. Ta
Well it is very wierd.
I formatted the sdcard both on the PC and also in the phone.
Despite this, the file explorer still reports the file structure - which now no longer exists.
I've rebooted the phone. Makes no difference.
Phantom file structure reported on the phones file explorer - even though the available storage size is correct in the storage stats.
Does the computer also report the phantom file system?
This seems really strange indeed.
Have you tried writing new files to the card on the gs3 then see if they show up in the computer?
Sent from my LG-P920 using xda premium
No. The computer shows correctly.
But now - even more wierd, I downloaded a lot of files to the phone's internal memory.
Although the SDcard is empty, the phone's file explorere now shows the SDcard as containing the files.
My head is spinning.
I wonder if this is at all related to my issue (http://forum.xda-developers.com/showthread.php?t=1698672). I also experienced a phantom file structure, but it only affected a few hundred picture and music files (out of several thousand).
Thanks for this suggestion.
I don't think that the issue is the same. It was never formated exFAT and also there is no trace of the files at all.
When the car is inserted back into the HTC there is no problem. When it is in the PC - no problem.
I have now tried with another card - 16gb. Same thing.
These are good quality cards which have been used for more than a year on other phones.
I'm starting from scratch today. I'm going to reformat the 16gb using a full format - FAT32 and see what happens.
It shouldn't neeed to be this hard
Just to reiterate:-
The really puzzling things are:-
The phone's faliure to see the files - but it sees the directory structure.
The phone sees a "virtual/phantom" directory structure after an in-phone formatting
The phone sees files on the card if they have been copied there from the internal memory.
have you tried another card with the same capacity? what about reformatting the card from the phone after backing up the contents?

Yup - done all of that. No difference
what ROM are you using? are you using a custom ROM?
No. Brand new received yesterday t-mobile s3
Is it possible that the internal memory and the sdcard are being spanned in some way so that to the file explorer they all appear as one?
In fact even my Profimail email application reports that the directories and files are on the sdcard when in fact they are now on the internal memory and the sdcard is newly formatted and empty
Are you sure that you try to access your sdcard via /mnt/extSdCard/ ?
Samsung points the folder /sdcard/ to the internal memory and not to your sd card, so please make sure this isn't the problem.
Sent from my GT-I9300 using xda premium
Ah - that sounds like a likely possibility.
Where can I find out more about this pelase.
Is there a way that I can point it at the physical card.
I really just want my phone to work in a way that I am used to and not in some wierd Samsung-controlled way
Yes, I can confirm that is what is happening.
It is really very ambiguous. ESfile explorer reports the directory structure on the external card but doesn't report the files. This is definitley a glitch which needs to be sorted out.
It also means that if you use windows file explorer to upload data directly on to the external card, it doesn't seem to be accessible to the phone.
Surely this can't be right

Recovery - Help

I am on a sprint LGLS990, rooted with twrp. I have just started doing backups. I did one the other day on the internal storage which worked fine. Now I'm doing a bu on the external sd and worked well until generating md5. Its said this for the last 30 minutes. It appears that it is stuck. Is there any way to stop or cancel this?? I tried pushing any of the hardware buttons in back, but power just locks it, then I swipe to unlock it. Please help!! I don't know if I can do a battery pull or not if that would stop it, but I definately dont want to ruin my ext sd card as I have sensitive info that I need.
Update - I did a battery pull and it just seemed to reboot it. Nothing wrong with my external SD card that I can see. I can successfully do a backup on internal but everytime I try on external it gets stuck on generating md5. I have searched google but can't come up with anyone that has had the same issue on the g3. It's a sprint with model LG LG 990.Any help would be greatly appreciated. Just a thought, are there any other recoveries that work on my model g3?

Is the card larger than 32GB, and formatted as exFAT? If so, that's likely the problem. Our bumped version of TWRP has a bug affected the ability to read exFAT cards. If so, you can copy all the data off to a PC (or Mac), reformat the card as FAT32, and test it out. Here's some info on how to reformat the card to FAT32:

If it's 64GB, it was probably formatted as exFAT from the factory. And yeah, you'll probably lose some storage space by formatting it as FAT32. How much will depend on what you have stored on the card. A lot of small files will waste more space than the same number of large files.
I just copied the external card to my desktop. I tried opening it up but it wouldn't open, saying it could not open that file. I even tried to extract and it said the same thing. I don't want to erase my card unless I know for a fact that my files are safe. With some apps, I have over 2 years of sensitive data that I can't afford to lose. Maybe it might be easier to just do a backup on my internal, then just copy and paste to my external.
There's a new TWRP that I believe fixes the exFAT bug:

I am rooted and have the latest twrp recovery, think it is 2.8.2. On this version, I am able to save my backup directly to ext sd. I have noticed however that when I do a backup, it takes between 30 to 40 minutes to do one. However, I just did a restore last night and it took over a hour and a half. I have only had the phone about 2 weeks. When I had my S3, doing backup would takes kess than 10 minutes, same with restores. Is this normal or is something amiss?? Thanks for the feedback.
Update-
I have also noticed that when backing up to the internal that it takes just a few minutes, now when I backup onto the ext sd it takes about 20 minutes. The issue I had above I believe is connected when I used twrp manager instead of booting directly into recovery from the power menu. But its still taking alot longer to backup on my ext vs the internal. What would be the cause of that??
It seems most have issues if you SD is more than 32g.
The recommended format seems to be Fat32 on any card. That may be your issue. TWRP shouldn't be taking any extra time.

I'm just wondering when I had my S3, I had the same card and did backups with both phiz and twrp and never had any of these issues and the backup and restore times were usually under 5 minutes. Now with the G3 I am having these issues.

It probably wouldn't hurt to format it and start over. Just like in the other thread I just answered you in. Start fresh and clean since you're starting with a different phone anyway.

I just formatted for 64gb sd card, moved all my files back onto the card, checked on my pc and it said fat32 under properties. I did a backup and halfway through the data backup it failed. I have updated twrp to 2.8.3.
Any suggestions on why I can't use the external card??

Did you format it in Windows/Linux as Fat32? Then move your files to it, and put it in the phone.
You may need to format it as 2 partitions.
Other than that, I really don't know what else to say.

I formatted it in Windows 8 but I had to use a third party program as Windows only had the options ntfc and exfat. I first deleted all my files, then formatted and copied all my files back, then inserted back in phone and tried a backup. In the third party software, I don't it gave a option to split the partitions.
Am I the only one having issues with creating and restoring backups on the external SD or ate others having the same issues?
Anyone else having issues backing up and restoring to the external sd card??
I'm just wondering when I was on the stock rom (with twrp recovery), I never had a issues backing up and restoring to the external sd card. Seems like this might be rom related, don't know, just a guess.
Also, are there any other recoveries that work with the G3, since it appears that twrp still has bugs.
I'm guessing not.
Pull your SD card out, or just make it backup to internal just to rule out TWRP.
Then maybe try a smaller card to make sure it's not your phone, or the pins for the SD card.
If the smaller card works, then you know it's the 64g card. It it doesn't, then it's got to be your phone.

I have done backups through internal and everything works fine. I think I might have a 32 gb card around somewhere, if I can find it, I will try that and let you know the results, thanks.

I just did a backup on my 32gb sd card. This card has not been formatted, its stock. It did do a backup but it took 40 minutes to do it. It appeared to get stuck on the last 1000 files when backing up data, the last 1000 files took over 15 minutes itself. I just did another backup, this time on my internal, it took only 5 minutes. How come its taking so long backing up to exernal, and thats with the 32gb card, still doesn't work on my 64gb card. Is anyone else have issues with backing up on a 64gb card?? I would like to know if i am a isolated issue or if others are having the same issues.
Try using Partition Master to format the 64GB card as FAT32, instead of exFAT.
