So I've been using SanDisk Ultra 64 GB sdcard since I bought my Max about 5 months ago. Recently I've been switching between CM11, NuSense and Stock Deodexed ROMs. I have used TWRP for the most part. Yesterday after flashing the new crDroid ROM, I tried to restore CM11 (of which worked) but afterwards my sdcard would not mount. It kept causing the whole system to crash and reboot. I attempted mounting in recovery to no avail. I tried using CWM- negative results. Now it doesn't even register in the phone at all and even causes my computer to become very slow while reading it. It will not mount in Ubuntu 12.04 but mounts in Windows 8.1. I've tried copying the content- negative results. Anyone experience this before.
I used to own a Droid Charge which had sdcard corruption issues and one person in the forum said the HTC devices can become corrupt when the "S-Off" becomes corrupted.

Any thoughts?
Yes, it has happened twice. Once on my 64 & 128 card which are Scan disk branded. I didn't get system crashing. I just had to format. I had the phone s-off since December and just experience it last month for the first time.
I lost backups and everything the first time but then started using Drop sync but with drop sync and my move to KitKat I have to move some of that info to internal and once backup done delete duplicate info.
I haven't experience it again on either card so not sure why it happen. I wiped the phone starting with fresh install after the first case but not the second. I haven't experience it after a format. I even used the phone for formatting the second time computer the first.
64GB External sdcard wont mount; corrupted

This problem also happened on my One MAX three times...
I am using stock ROM.
I have to format my 32g card three time......
so, I learned, data backup is very important.

I've read upon the DAMAGED SD CARD problem with android, but most of the phone becomes virtually unusable, mine says it's damaged but market works, and I can install apps to phone memory, even with APPS2SD enabled. If I try and copy my files to the computer, it stops halfway with 'perimeter incorrect', glad I did a backup like 1 week ago. Funny thing is, in recovery the SD card is fine, I can make backups, I even tried to repair SD Ext Partition, no luck.
Its probably Android thinking it's damaged without it really being so. Totally confused since I warning/error is on the ongoing notification. Also when I go into the SD card & phone storage shows information as unavailable and SD information widgets can't read it either. I don't mind formatting and copying everything over, but it kinda works, but android thinks it's corrupted or something. Very weird. Also I did nothing out of the ordinary, but with computers or machines random errors can occur. I had the partition in place for a 3 weeks now, installed MCR 3.1 couple of weeks ago and using it pretty much like this, but since the WIFI hanged (kept saying it's turning off but being stuck) I rebooted and the message came up.
Is it possible to fix it how it is? Or shall I just re-format and copy everything again. I'm just worried it may happen again.
Hi,
i've got a little problem with my new SD-Card.
Actually i'm using an ICS ROM for HTC Desire with reverse mount. With my old SD-Card the whole system got really slow and laggy although i tried several settings in the ROM. So i bought a new one (Sandisk Ultra Mobile Class 6 - 16 GB).
My old card has a FAT32 partition and a little EXT-3 partition for the reverse mount option. I've read that EXT-4 is maybe a bit better and faster and more reliable so i decided to format the new one as followed:
14 GB FAT32 primary partition
1.4 GB EXT-4 primary partition
I've formatted the new SD-Card in my PC with "Mini tools partition wizard". Everything went fine until then.
Then i made a NANDROID backup of my old system onto my old SD-Card and copied alle the files from the old to the new card (FAT32 only). Then i put the new card into the phone and tried to restore the system. It worked but the system acted really strange (i think because of the change from EXT-3 to EXT-4 file system).
So i wiped and cleaned everything and made a new install of the ROM with reverse mount activated. Everything seemed to be ok but when i started to install Titanium backup to get my apps back the phone reboots at the beginning of the installation progress (after download). I made three installs of the ROM but it's always behaving the same way. Is the new SD-Card broken or did i mess things up when formatting the card?
Thanks in advance for your help.

Ok i've solved the problem by myself. Thread can be closed.
I'm the 4 genie and I'm extremely frustrated with my evo. While fixing separate issues, I tried flashing something and now it's got an error that E: sdcard (the evo's internal memory) won't mount. It's corrupted i think
It just sticks on the splash screen when I boot up, but the bootloader's and recovery are still here
So far, I've tried formatting it with several programs on both a mac and pc. I tried moving and copying files from the sd card to the internal "sdcards."
I am so sick of this phone, it's caused nothing but problems (first one i got had signal issues, this one ran slow and got even worse signals when i upgraded to JB).
I'm on TWRP 2.5.5. S-ON, HBoot 1.19
Please help me resolve this problem.
I am having the exact same problem. From what I've found on the rest of the internets it seems like we need to reformat (preferably with windows). But I only have a mac so I havent tried that yet.
You guys can try something like this.

If you don't like the phone, then just trade it in or buy another. Coming on and saying how much you hate the phone isn't going to do anything.
That being g said, you probably had a bad flash and it corrupted the internal ( like you said). Most of us have done it at least once. Format the drive, and there you go. That's what fixed it for me, and usually what works. It won't fix your distaste for the phone, though, or your signal issues.
Sense ROMs tend to have better signal than others with my phone. The Sense 5 port is pretty nice, but there are plenty of others that work well. If you've tried the sense ROMs already, then go with AOSP. Some people have better luck with those.
If you still don't like it, then get a phone you do like... Hell, I'd be happy to send you $50 for the phone if you don't want it, I could use another to play with...

How do we format the drive if nothing can SEE the drive? The same thing happened to me. I can't get to the internal sd card.
Every time I had the memory corrupt it was from a viper dirty flash. All I ever did was wipe both caches a factory reset wipe security them mount internal to my PC and format. If this is still at no avail then I would wipe internal storage and let TWRP format the drive for me. I have never had both methods fail. The corruption of the internal storage is why every dev insists a full wipe and factory reset after flashing a new Rom

TWRP will see the drive.

ugh, gotta get this working so i can get a trade in credit toward my iphone 5s
Interesting issue. I've fixed the issue on other EVO LTE's simply by mounting internal storage while connected to a PC, then formatting it. I can't think of a reason this wouldn't work for you:what:
ok, i've mounted it to the computer as mass storage several times on 4 different computers and formatted it, but to no avail
at the top, it will only mount the sd ext card..... maybe i've mounted it wrong? where do i mount it?
also, the micro sd card is the only thing it wants to read... is there a way to install the ruu (just a stock rom) and boot it from the sd card?
thanks again for the help!
Sorry for the necro, however I had this issue recently and finding very few fixes so thought I'd put something out there.
Now my fix was very simple, so I don't know if this will work for everyone. That being said, the ROM has been buggy now.
Phone: Samsung Galaxy S3 - i9300 (international version)
ROM: Pac-Rom 4.3
Recovery: TWRP
Issue:
when starting phone, it is stuck on the "Samsung Galaxy S III" logo screen.
Troubleshooting:
I was relieved to find that I could boot into recovery (TWRP).
From there my first instinct was to wipe my phone and re-flash the ROM... BUT when I tried wiping, I got an error. The log said something alogn the lines of "cannot mount internal storage" or "internal SD". I can't remember.
So I freaked out thinking my internal flash storage was fried, BUT why is TWRP working then?
I connected a USB cable to my computer to see what happens. Windows 8 picked up the external SD card, but not the internal phone storage.
Fix:
I would usually NEVER flash a ROM without wiping first, but thought I didn't have much else to lose. I tried flashing PAC-ROM 4.3 without the wipe and it said "successful". WTF? I didn't expect that.
I rebooted and everything worked fine. The ROM wasn't stock either, it had all my settings and icons on my home screen in tact.
Since then, the ROM has been buggy. Youtube app disappeared and wouldn't search properly in play store and the apps drawer had all these com. files f or the google apps (this was still there when I re-flashed GApps).
So I was able to save my phone, but had a bunch of issues. I have since flashed to PAC-ROM 4.4 (Kit Kat). I very much miss the PIE controls and Halo, but it is extremely stable.
Here's what I did when I had the same issue. Take out the ext SD card. Then, plug your phone into your PC. Format your phone with windows, it should appear as a flash drive or something like that. After that, I replaced the ext SD, mounted that with TWRP, and formatted that, too.
I am having an issue creating backups. Last time I had issues with what seemed like the sd card, I bought a new 64 gig card and replaced my old one.
The old one still works fine with an adapter into my pc, but I wrote it off and sucked it up.
I just tried again making a backup in TWRP with an error, "unable to create backup folder". So, I switched over to CWM and tried the backup. Same issue.
I just checked with my phone plugged into my pc and the file system is defined as "Generic Hierarchal" which I've never seen before. I am almost positive I formatted it initially as either fat or ex fat. With the phone on, I have no issues with the card. I have music and other data on it and it reads just fine.
Other possibly relevant history:
previous rom was Beans 21 and was unable to update to 22 (do not remember the error)
wiped and loaded Alliance's latest V8 with no issues. Been running Alliance for a few weeks now with zero issues. (other than backup)
Do I need to wipe my card and format it in the phone? I think previously I formatted it in my win 7 pc with an adapter.
TIA for any info
Formatting the card with TWRP is probably better
I had this issue with an S3 and nothing would work. I tried mounting/remounting, formatting, and even a new SD card. It finally worked with a new SD, which is really weird because it was an old SD card compared to one of the newer ones.
Thanks for the response. I have 2 cards. Just cleaned off one and formatted in the phone. Still fails trying to do a backup. I hate the thought of buying a third 64 gig card.
I think I'll try going back to stock and see what happens. It'll be a while before I can. Sucks I can't backup first.
Thanks again for the response
interesting update, for anyone that might be watching this post: I d'loaded skips updated toolkit from here: http://forum.xda-developers.com/showthread.php?t=2052788&page=10
and was able to make a backup.
just FYI
Bought a Sammy 64 and same issue. Unless anyone has any other suggestions, I'm going to Odin back to stock, I guess.
back to stock, unlock, root fixed it. just fyi.

Not. Tried to load another rom and can't read from ad card. Damnit. Any help would be appreciated.
more drama...I re-loaded twrp, b/c I found an old post with roughly the same issue. It said to use cwm to fix permissions. Well, cwm doesn't offer that anymore, the comment is that it was placebo effect. twrp still does offer it. I ran it and then rebooted to android, then rebooted into twrp reco again and was able to load Alliance v8 again.
so, until 4.4 roms appear (which I will have to go back to cwm for, unless twrp gets updated) I guess I'm set.
I'd still LOVE to hear from someone who might know how this happened or what exactly happened, to know what to avoid.
Thanks again, to the one person that responded.
Back to square 1, cannot make nandroid backups.
In CWM v6.0.4.3 here's the errors:
trying to backup: Can't mount Backup Path
trying to mount external_sd: Error Mounting /external_sd
In TWRP v2.6.3.0 here's the errors:
trying to backup: backup folder: /external_sdcard/TWRP/Backups/
E:unable to create folder: /exterenal_sdcard/TWRP
E:Failed to make backup folder
Any thoughts? I know I've posted this multiple times, but not sure where to turn. I suspect if I go back to unrooted stock again and unlock / re-root, load twrp and fix permissions, it will work again for a while. But not permanently. I really want to fix this once and for all. But am not getting any clear direction to go. I have searched on and off XDA to no avail. hoping this time is the key. Thanks for reading and potentially helping.
I use a 64 GB sdcard on Slimkat rom for HTC one max. That is, I try to use it, but with no success. But the problems I describe below are true for my previous sdcards as well.
I formatted the sdcard on the phone, on my previous phone Galaxy s3 and on the PC win 8. Whatever I did, every time I lose my files and I have to reformat again.
The problem is, whenever I copy several files onto the sdcard, they always get corrupted. I copy let's say ten movie files with different sizes (700mb-3gb), but at one point some of them are suddenly being listed as zero sized files and lots of new files with non-ASCII characters in the filenames appear. Sometimes they appear directly in the Lost-and-found folder.
Sometimes I just get a "sdcard is corrupted" notification, so I can't access the sdcard at all.
Then after waiting for a few days, without doing anything, the card gets recognized again and everything works perfectly again, without the need for reformatting the sdcard.
On previous phone Galaxy s3 and previous sdcard I got lots of "preparing sdcard" notifications right after waking/unlocking the phone.
This is my 5th or maybe 6th sdcard. Sometime the sdcard lasts for a few weeks before going corrupt, sometimes it starts within a few days after formatting.
In short, I try to use the sdcard as a secondary drive but with no success.
I'm on Slimkat Rom btw.
In the past I used 16 gb, 32 gb and now 64 gb sdcards, from different vendors (Samsung class 10 currently).
One thing, I use different adaptors for charging, sometimes 500 mA sometimes 2000 mA. Could that lead to a corrupted sdcard?
Is there anything I could do to find the cause of this?
What would you do?
Any help is appreciated!!
