Help needed - external SD card probably wrecked - Galaxy S III Q&A, Help & Troubleshooting

As the subject says, I think I've wrecked my SD card, but hoping there might be something I can do before formatting.
I was using the Solid explorer beta, and launched DiskUsage from within the app to check the SD card. This caused a crash to black screen, and I eventually had to restart the phone. However, when the phone booted, it could not detect the SD card, and now tells me the card is empty. It's not detected by any app, I can't mount it from either within android nor from recovery.
I realise I'm probably screwed, but any help is appreciated.
Currently rooted, on stock ROM and CWM Touch recovery.
Cheers,
Erik

Through Windows try something like RECUVA and a card reader .

Thanks, I'll try that once I'm home at the pc. I've emailed the app developer as well, and waiting for a response from him.
Cheers,
Erik

Backup the contents of your SD to the PC, format SD, and you should be good to go.

Back it up somehow, do a complete format of the card, then move your data back onto it. If it still has issues, format it and put no data on it until you've verified that the data is good. I've had issues both with the card being corrupted and data being corrupted that's led to unrecognized cards and random unmounting of the card.
Also, there's no point in wiping more than once. Anyone who tells you it does do something it lying to you.
Hey loon thanks for your words of wisdom seriously, I've done everything you mentioned,i may get a new SD card but I Will try your way though wish me luck homie

External SD Card

Suddenly my S III cannot see Ex. SDCard files! & it is showing an icon of sd card in the notification bar.
Going to settings>storage the card cannot be seen & the only available option is <Mount SD Card>!
I tried to get out my card & connect it to my tab. Unfortunately it is not seen as well which is pointing a problem with the card itself.
I also added a different card to my S III. it could be read normally!
I think it is clearly a problem with the card itself, but I wonder what might have caused it to happen! & if there is any way to restore saved files on the card.

Hi
1) You have a corrupted file system on your SDCard. Why ? I don't know. To solve the problem, try using one computer with Windows because SDCard use FATfs (completly support by Microsoft)
2) You have a broken SDCard, and no chance to restore your data. Sry !
Thank you!
You are completely right. Trying it through a normal windows PC is a good idea. I'll post back results once I do. Thank you again!

Hello,
If you like someone to help you, you must provide clear description of your problem - just precisely describe step by step what you did using understandable English.
For example what does it mean?:
"transferred my sd card" - what card (internal, external) what transfered? All data? or maybe you took out your external card and put to friends phone???
"put a zip" - what zip? containing what?
"my friends app don't work" - what app? etc etc
I think, noone yet answered you because the others are cofused as much as I am. So decribe it better + provide information on what rom/kernal you are, then we will see how to help.
Regards
I had a boot loop problem, cause I changed the boot logo. so I used my friends ext SD card to flash the stock boot logo. my friend had apps on the ext SD card and when he put his card back in his phone some apps mostly games were there but its icon was replaced with a gray icon that said 'SD' and when I launch it it says application not installed. wierd because when I go to manage applications it appears. and thx for the reply

Unfortunately I think that it concerns apps which were installed (moved) to external SD card and after removing SD card from the phone, data on the card could have been broken/corrupted, so that after putting the card back to the phone apps can't be recognized.
I'm not big optimist but you can try:
- move apps back from external sd to internal one (probably not possible)
- Back up the apps - if they are visible by eg. TitaniumBackup
- Unmount, mount again external sd card and reboot the phone
Regards
tried and didn't work. thx anyways m8

It's true, the files have become corrupt. All you can do is uninstall them, and re install.

may have screwed myself (s4) just now..

went to flash a new rom and was running low on storage space so i went into twrp and wiped everything including sd card and internal. So the catch is i had the new rom i was going to flash on my external. now im pretty sure if i exit twrp there will be nothing for the phone to boot on too.. and i have no way of putting anything on my sd card..
what can i do?
Use adb and a computer to push the file onto your phone. There should be a setting in TWRP to allow the phone to be seen by adb.

A usb card reader could help. Or find a friend with a phone that takes sd cards.

This is definitely the next best option if you're not comfortable with adb.
