[Q] Corrupt SD Card during Gold Card process

After my "kefuffle" with http://forum.xda-developers.com/showthread.php?p=8484070#post8484070
I had to play around with making multiple gold cards. Unfortunately one of the cards I had to use was my 32gb SanDisk microSD. After editing the hex code during the gold card process my computer failed to read the card. I then proceeded to format the card.
Windows explorer can't format the card in quick or full format mode. I downloaded a third party SD formatter (Philips or something) and ran both a quick format, and a full format on it. After running the SD formatter windows explorer was able to recognise the SD card as having 31gb of spare space. I was able to copy files to the SD card.
As soon as I put it in my Desire, it said random errors like "SD card ready to dismount" and "SD card damaged please format". After formatting the card with the Desire's format tool, the card is recognised and it says there is 31gb free space. I am then able to plug the Desire into the computer and enable "HTC Sync" or "Disk Drive" mode. HTC sync doesn't recognise the SD card, but windows explorer does when it is in disk mode. I am able to copy files to the SD card, although as soon as I eject the phone, the Desire attempts to check the SD card for errors and says the card is damaged.
Surely there is a tool out there I can use? It has the functionality to store files some of the time, surely not all hope is lost? 32GB microSD cards are freakin expensive and I don't want to throw it out...

Get a linux live cd, start GParted and delete every partition on the SD Card. Create a new FAT32 partition and try it again.

Sorry I'm nub, what the hell does that mean?

http://gparted.sourceforge.net/livecd.php
Grab that and burn it to CD/USB/whatever, and use that to delete all of the partitions on your card (plenty of guides online for GParted)

I got that problem too but my 16gb microsd read only 8mb. Can't format. Gparted can read as well.. :'(

I had the same problems with my SD card on my HTC hero... don't panic I solved it with this software...

This is the instruction video that I used to understand what to do and create an ext2 as well...

For me worked like like a charm!

I tried that but it didn't work. I was able to partition it, however once the software had applied the partitions, it showed up as "Unformatted", "Other" and "other". Whereas in the video it showed up as "Fat32", "ext2" and "linux swap".
I tried it in my Desire anyway, and it recognised it, but if you took a picture then connected the SD to the computer as a disk drive, the image taken becomes jumbled (literally). Once ejected from the computer the Desire is unable to mount the SD card properly and says it is in "Read-only" mode. In that state I am unable to eject/format the card.
I haven't tried Gparted yet. Wouldn't that be the same as deleting and creating the partitions?

I see.... I don't know about Gparted, but now that u remind me, also for me it didn't work immediately..
I don't remember what I did exactly but I formatted the sd card 3 or 4 times, after I use the video's method, and I also formatted once with win7 and at the end I formatted it again with the phone..
I did it and suddenly the SD started to work properly..
Now is working perfectly since I've done it and that was 3 weeks ago..

it doesnt work with my MicroSD.. it still shows as 8mb when it should be 16GB!! guess its corrupted like hell..

Tried Gparted...I was able to create a fat32 and ext2 partition (wasn't able to do ext3 or ext4 or linux swap - kept saying "sd possibly corrupt") However still had issues with phone reading it.
I'm just going to take the card back. I've had it a month, but worth a try.

Could be... did you try to format the SD with windows first?

[Q] SD card not working after rom manager backup

Hi guys, I am running CM7 on my EVO. Today I did a backup using Rom Manager and after the phone rebooted, the SD card stopped working. I cannot mount it. I tried connecting the SD card to my computer using a USB adapter and the card cannot be read. There are pictures on my card which I really need.
I'm pretty sure my card is messed up but if anyone has had a similar problem and found some fix, please let me know.
Thanks.

If you haven't already done so, boot into your recovery and attempt to mount the card via the MS-USB option.

I went into clockworkmod recovery and in the "Mounts and Storage option", I first tried "mount /sdcard". That failed to mount the sdcard. Then I plugged in my phone to the computer and tried to "mount USB storage". It says "Unable to write to ums lunfile (No such file or directory)"

Any chance you've got a card reader/ adapter? If not, you can buy one at radio shack for like $5

The card *may* very well be corrupted and if you've tried this them disregard. Sometimes, powering off your device and then removing and reinserting the SD card helps. Afterwards, connect your device to your computer and boot into recovery. Once again, try to mount the card from within recovery. If you're still unsuccessful and have a spare SD card, shutdown your device and swap cards. Download the PC36IMG.zip for amon RA v2.3 from http://forum.xda-developers.com/showthread.php?t=705026, place of on the root of your SD card and boot into the bootloader to flash it. Installation takes less than 10 seconds. Afterwards, shutdown your device, switch back to the corrupted SD card and then boot into your new recovery. With your device connected to your computer via USB, select the MS-USB option from within recovery and see if the card mounts properly.

[Q] HTC Desire SD Brick? Can't BOOTLOAD, help!

Hi everyone,
I've had a bit of a search on here, and although I can find threads about SD bricking, I can't quite find one that matches my situation.
I tried to root my phone and flash my first ROM today, I thought it'd gone ok, partitioned using GParted and flashed the GingerBurst ROM, and seemed to start up again ok. I was going to add something to my SD cards though, and found my USB connection menu didn't included the usual use as disk option and the SD card is now inaccessible from both my computer and the phone.
Under Settings->SD & Phone Storage, both Total and Available Space fields are 'Unavailable' and Mount SD Card and Erase SD Card are greyed out.
I've tried getting the bootloader up to see if I can do anything by holding down the volume down button and the power button (phone doesn't even turn on and screen remains blank), so I think my phone no longer sees that as a recognised option. I've tried back+power and up vol+power (for fastboot), and I get nothing. All my phone will do is power on if I hit the power button, so now I really have no idea of how to get the SD card back up and functioning.
I haven't tried repartitioning it because if my computer can't see it, and neither can my phone, GParted surely won't... I also don't have a card reader.
Is there anything I can do? Is there another way to get the bootloader up? Did the key combination change with gingerbread? Maybe I went wrong somewhere during my rooting... I don't know. Any help would be very much appreciated!
Thanks,
Daisy

You need to either get a new spare card, Format in FAT32 then add a 1gb EXT3 partition, or get a card reader and reformat you old card again with FAT32 first then EXT3 second- if it doesnt work, bin it
Dont worry about losing applications you can download these again from market.
Ensure your card is properly formatted if using A2SD
Wipe your phone and caches
Install your ROM from the SD card
re install applications
Enjoy

Please use the Q&A Forum for questions Thanks
Moving to Q&A

You have to press and hold first volume down (for hboot) or back (for fastboot) and then the power button. It seems as if you doing it the other way around.
Otherwise, you can do it so: When running rom, use restart option from shutdown menu. Then press and hold back button.
After you successfully booted your phone into fastboot mode, set up adb / fastboot (for a guide see my sig), connect your phone to computer, open command line on computer and type
Code:
fastboot oem enableqxdm 0
.
Now reboot into rom. Your desire should now recognize the sd card.

Hi, thanks for the info! I've tried all the instructions here: cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK#Windows
I got to 14 - but no drivers were automatically installed, and at 16 what looked like a command prompt style window popped up for a split second and disappeared - no information that I could read on it in that moment anyway, I did try again but same thing, so I continued with the steps to check, and tried it again after step 28 with the same thing happening again.
When I try to boot in fastboot mode my phone looks as though it's just starting normally - should anything be different? I don't know what fastboot is meant to be like! I also tried the piece of code you included in your message there and brought up a window that said it was waiting for the device, but made no progress...
I am correct in thinking I should be entering these prompts by going Start-> and typing 'run' in the search field, and then entering the prompt there? If not then that might explain something!

Seems to be an usb brick. On xda you find a guide how to solve it.

[Q] SD Card removed

So to make this as quick as possible, basically I didn't touch my phone for 3 hours and it was fine before that, I then checked my phone and I noticed it turned it self off, so I held the power button down and it reset itself. Then noticed that this message was being flashed in the notifications:
"Removed SD card.
SD card removed. Insert a new one"
I removed it and placed it back in but that didn't do anything, the message continued. So I rebooted my phone and that didn't help, so I then decided to wipe Cache+Dalvik in-case that might help, but that also didn't. (I am running on the latest AOKP build by task650).
I plugged the card into my PC and it doesn't appear anymore, so I placed it back into the phone and clicked the notification, it was to format the sd card, so I accepted it, the phone reset and the message still occurs and it won't appear on my pc.
Also, I downloaded SD Card monitor and I got this report in approximately 30 minutes.

Sounds dead to me. Happened to me once. I just replaced it instead of trying to recover it.

Happened to me also, but i fixed it. Heres what i did : 1. Pull the back off your phone
2. Press mount if you have the option and pull the card as fast as you can then put it back in and press mount again. It should then pop up but before you keep using it i would backup everything to your computer and format the ext sd or it will happen again. (i did this on my s3 and tab 2 with touchwiz custom roms) 3.

*sorry for my bad english.
hope it will help everyone where facing this issue :good:

Hi, Kick.
It's a great and clear tutorial. Congratulations!
Maybe I'm wrong but I think you need Android 4.2.2+ for full SDXC support, and you can also format your card directly in your mobile.

I've installed a Sandisk SDXC 64 Gb and the mobile keeps unmounting it when I copy a great volume of files, even after formatting the disc with this utility. Really don't know how to solve this (and I'm in Stock 423).

copy from internal to microSD ? some thread said if 4.2.2 have support exFat, how many GB your file ? more than 4GB your card must be in exFat system.

The problem happens when I copy many (400+) little (< 400 Kb) files at once from the computer to the exFAT formatted SDXC SD Card, either in MTP or in MSC USB mode.

oh, i always take my SD card (unmount first from my phone, if not it will damage the card) and put to my pc when i need copying many file, it more faster than using USB connection
if you using usb connection, phone will run media scanner when you copying the file.

EDIT:
I tested carefully now, and discovered that the problem occurs even when I copy files between the SD Card and the internal memory, even if I disable Media Scanner with Rescan Media.
It seems you're right about the computer. I removed my SD Card, inserted in the computer, and could copy a whole universe of files without problem. It proves that the problem isn't in the SD Card. But I need a better solution than remove the SD Card every time I want to use it (to avoid wearing the socket, the card etc).
It should work faultless from factory. It's a sad thing that we are having this trouble.

yes problem occur when we copied file (many) from internal to ext-card, i think thats defect from the product or system, have you tried another microSD class 10 (not UHS) ?
try this --> put .nomedia file in folder (microSD), where you want skip that folder when mediascan run.

No luck with .nomedia here, nor when I disable Media Scanner with Rescan Media.
