So I bought a 64GB microSD card but I think it might be bad?
When I download a ROM and check the MD5 on my desktop, everything matches up. However, if I transfer it to my sd card and then check the MD5 again, its wrong. This only applies to my external sd, if I move it to the internal storage, the MD5 checks out. Furthermore, my TWRP backups that I create on to the external sd always fail restore and the phone is unable to boot from it unless I reinstall the ROM fresh. Kind of an annoyance making my sd card useless....
Is this a problem with my actual card, or something else?

Did you format the card in phone?
Yes
If it's new and you can, I'd return it. Don't take chances.
Would suck if it were a chinese knockoff remarked card. They do that. Take a 4gb card and remark them and crap.
What brand is the card and where did you get it from?
I have a bad SanDisk 64 gig I got from Walmart that don't format or erase anything . If you have that brand take it back asap I had my card for 3 months before it messed up.

I just bought a Kingston 32GB class 4 micro sdhc card. it seems it is not working correctly. here are the symptoms:
1. after the first time bootup wizard, several apps (widgets, settings apps) crashed.
2. every reboot it start the "first time startup" wizard.
I am not sure if it is a faulty card or I missed a step installing android on my card. All the builds I used work on my older 8gb card.
can any one help me with this problem?

Try to reflash your rom to with task 29,format the card,and install android fron the begining,not a copy from your old card,and install all the app manually again,not from a backup,,maybe this will solve the problem!
Try doing a fresh install instead of just copying files over.
I did try a fresh install. I didn't copy my old install to the card. I tried 3 different builds (fresh).
at the last try, I did a diff on the sdcard and the android build folder, it seems files are copied over to the sdcard correctly.
but everyboot it launches the setup wizard. it seems data are not being save to the sdcard in Android.
Where can I get task 29?

This will help.. Its from DaDoctor in the Core Cell Evo Rom forum.
"If you are experiencing odd behavior from the ROM (random freezes, slow down, etc) download and run task29. Please be sure you UNDERSTAND what you are doing! This app will format the internal memory of your HD2, removing any trace of previous ROMs, Radios, ETC. So, after the application runs, you will have NO OS on your phone! You will have to flash from SD or from RUU via bootloader (by holding the volume down button on bootup). http://forum.xda-developers.com/showthread.php?t=644781"
Check the datasheet, find out if high speed 32gb cards require a different clock speed. This is the case of sd versus sdhc.. I'm guessing it doesn't tho, as 32gb is under the sd 2.0 spec. Create a working android 'folder' with another card, transfer the contents to the new card - see if you still have problems. And yes, I understand that is the opposite of what has been said in this thread.
It doesn't seem like a task29 will help. This is an android related issue with the change being a sd card.. Formatting the nand seems strange.

Hey buddy!! Bad news for you. Kingston doesn't make a class 4 32GB microsd cards yet!!! I am assuming you bought it from ebay. There are some people out there who modify a 1GB or 2GB or 8GB card to report it as 32GB. But when you try to write data on it, it gets corrupted.
If you want to check this is the case or not then
format your card. Put a lot of data on it(movies, songs or anything you want) and fill it up all the way. Now try to copy the data on a different computer. If you get errors while copying, your card is reporting a wrong capacity and you can file for a money back claim on ebay!!
Edit: Here's a link to such Kingston 32GB cards which sells for $10:d

I have been running android on a SanDisk 32gb class 2 card from amazon for a couple of weeks now, no problems. The card is noticeably slower(%75 or so) on android boots then a 16gb class 2 card, but after that it is the same. Well worth the extra storage.

Hello,
Me and my co-workers have exactly the same Phone GT-i9100, we bought exactly the same Micro SDCard, to the same provider, and Im the only one that the phone is not recognizing the SDCard. This is what I get:
http://dl.dropbox.com/u/52817124/SC20120124-143033.png
We switched SDCards and again I´m the only on that the phone does not recognize the SDCard, and then I tried with an used one (4GB) my partner was using before and it worked, so Its not like my phone does not recognize ANY SDCards!!! So I dont understand how come the NEW 32SDCard is not working ONLY FOR.
Any help would be appreciated!!! Thanks in advance,

May be trying this check list:
Mount SD card
Format SD cad>Mount SD Card
Format SD cad in the other phone or PC>Mount SD Card
Try Stability Test V2.3 in the other phone
Try SD Tools V2.4 in the other phone
Dust inside the SD socket?
Have you tried formatting in your phone?
Could be you got unlucky, and got a faulty card reader in your phone. But also possible the sd card just needs to be formatted.
What kind of sd card is it? And is it formatted already?

It won´t Mount to the Phone, when I hit "Mount" it would keep on saying Mounting but it doesn´t... When I connect the phone (with the SDCard in it) to the PC the SDCard is not shown. However, it does if its in my friend´s phone.....
Im thinking it could be that my phone is rooted, unlike my friend´s. So I think I could take it back to its original ROM and try, if it doesnt work then take it to warranty cuz the SDcards work just fine in my other friend phone (which is the same one as mine, bought it together, same day, same company).

Yes it is formatted, did it twice in my friend´s phone. I dont think its an sd card problem, its more like a feature/option thing, which I dont get to see any solution but to flash back to stock rom the phone.

Right; I mentioned the card as a POSSIBILITY, but that another possibility is that the card READER in your phone is jacked up. Root should NOT have any affect in your phone's ability to read an sd card. I have root on my phone, and it reads my class 10 16gb sd card just fine. But it may be worth it to try flashing back to stock to see if that helps. Otherwise, your only option left after that is warranty.

The thing is that it can read a 4GB micro sd that my other friend was using before, thats why I think it has something to do with my phone not reading that specific type of SDCard for some reason. I think of going back to stock because Root is the only difference between mine and my friends phone/MicroSDCard.
I´ll let you guys know my results in case someone else finds the same problem.

Sounds like it is having difficulty reading SDHC (High Capacity) cards. I think standard SD cards can get up to 8GB, so I'm betting your 4GB card is a standard micro SD, and not an SDHC. SDHC was created for 16 and 32GB.

Ok discard software related problem:
1- Flash original ROM-Kernel and try,
2- Then discard hardware related problem(in the phone and the SD card side)
Phone side;apply an electronic spray cleaner in the socket an SD Card. Use an anti-static wrist strap
3- SD card side; use software tools i recommended before in several SD cards.
Just to let u guys know, it was a hardware problem. I had to get a new phone.

Cant tell if its blur from the camera or is that label printed at an angle?
Either way, its more important where you bought it, not its appearance. If its ebay then thats an immediate red flag.
Use h2testw.exe to test the card on windows. You probably need a card reader / phone that has usb mass storage mode.
This will tell you if its fake / faulty.
Essentially, fake cards are smaller (cheaper) but programmed to look bigger, so when you hit its true capacity, it starts over writing the older files.... hence these issues.

I have a 1 gig sd card I know 1 gig lol. It was in a company phone I got anyways. it worked fine for past 13 months but now i cant mount it. phone does not recognize it and recovery comes up failed when I try to access it through it. you think its a bad sd card or bad sd card reader in phone? I do not have another phone to test the card in. If/When I buy a new card and it still does not recognize it how do I go about loading a rom? As of right now know back ups and did a System refresh stuck on start up screen on phone . All of this started after I did the sdcard mod on one of the roms beans I think.

If you are talking about the SD card swap mod..... It would require much much more room than 1gig. That might be your entire problem.
Can you take the SD card to a computer via a card reader (you might need an adapter to make it full size) and format it? If you can just load up beans19 on it and flash it. It should work if that's the issue. just don't try the SD swap with less than an 8gig SD card next time

I was in ES file explorer trying to move files to my external sd card and all of the sudden I get an error saying task failed. I can't delete or copy anything to my external sd card now. It's a 64 gb Class 10 Sandisk Ultra micro sd card. I formatted it to Fat 32 a long time ago. I don't know what's going on. And now all of a sudden Root browser in Root Explorer doesn't work either. I can't write anything on my phone. I even reverted back to stock android to see if it was the rom problem and that wasn't it either. I'm completely lost in the dark now.
I'm running CM12 Beta on my G3 if that means anything.
Try getting into it via twrp I had a problem like that a while back and I tried twrp and it did work I ended up wiping via twrp. You can also try putting it in your computer and partitioning it. I my self repartitioned it and just deleted the current one and made a new one. It seems that some roms or apps ect can cause the software in the sd card to become corrupted also try mounting and unmounting it before you delete anything.
If you are rooted you need to download SDfix from the play store. It says kit kat but works with 5.0.X fine. SD write access is still limited in lollipop unless the app creator allows SD access. If you were on zv6 on a custom rom it was probably baked in.

Yeah I tried formatting it and everything. The micro sd card is stuck in read only mode. I think it's dead. I put the micro sd card back into my S4 and my S4 couldn't write to it either. I ran CHKDSK on command prompt and it said that there's a corrupt file on the mciro sd card but it can't repair it because the micro sd card is stuck in read only mode. I tried to format it usng the SDFormatter and nothing is working. I used google and people are saying that when a micro sd card goes into read only mode it means that it's about to die. :c sucks cause it was 64gb and I've only had it for a year.
I had 2 SanDisk 64GB cards go bad soon after I formatted them to FAT32. I don't know why, but it happened. SanDisk could not explain it, but they were really good about replacing the cards.

I would contact SanDisk about it but I got the SD card in October of 2013 from BestBuy as a birthday present and I don't have the original packaging or receipt so I don't have proof of purchase so I doubt I'd be able to get the micro sd card replaced.

Chat with SanDisk. IIRC, they didn't ask me for a receipt, just where and when the card was purchased. It has a lifetime warranty, they will replace it and will even send you a free shipping label.
I have the same problem, I was copying files to my external sd card from internal and all of a sudden it said "moving files failed" and then nothing on my sd card would show up, though on storage information it shows that it's mostly full. But all the files are unreachable until I reboot then everything is fine while I'm listening to music, but if I stop for a while or try to move anything it messes up again. Anyone know of a fix?
