OS: Android 2.2

Device: Samsung Galaxy S

All of a sudden my external SD card has stopped working.

Error Notification:

> Blank External SD card
>  
>  SD card blank or has unsupported file system.

The last thing I did before this was to record some video, which was set to record to the external card, and then plugged it into USB.

I also installed USB drivers for the phone from Softpedia as Windows wasn't recognaising it by default. After installation the phone's memory showed up as a removable disk but the external card did not. Then after unplugging the device from the PC I had that error in the notification bar.

How do I recover my SD card? Do I need to format and therefore stand to lose the data on it?

What device and OS version? –  Matthew Read Dec 19 '10 at 16:28
    
Second Matthew Read's question. It's always a good idea to at least mention what device you are using and what version of Android. –  Matt Dec 19 '10 at 19:52
    
I stated both the device and the version of Android in the tags. –  bcmcfc Dec 19 '10 at 23:09
    
In that case you might want to note the SGS has SD card problems on 2.2: android.stackexchange.com/questions/3437/… –  Matthew Read Dec 20 '10 at 4:46

I clicked format on the device, causing the SD card to show up again in Windows.

Format thankfully did not actually format it - in the sense that it didn't wipe the data. I only know this because I have installed the demo of ZAR, which has found image and video files to recover.

My options now are to either buy the full version of ZAR, on the assumption that if it recovered images and video the other data is intact, or to find an alternative program that's free.

Edit: I am currently running PhotoRec, which contrary to its name, has so far found mp3 files and a txt file to recover. I am hoping it's also able to read obscure or non existent file extensions, so that apps which had decided to locate themselves on the SD card can be recovered.

It now shows up in windows. What happens when you just browse to it in windows explorer? Also, you shouldn't need a recovery program unless your SD card is corrupted, at which point its a long shot because there is little to no data reminance on flash memory. –  Matt Dec 19 '10 at 19:57
    
Clearly the data is recoverable, or PhotoRec and ZAR would not have been able to recover media files. –  bcmcfc Dec 19 '10 at 23:15

Sounds like Windows had an open file handle when you disconnected and something got corrupted. I would attempt to copy everything over to your computer and then format it. Get the USB drivers from somewhere official.

How can I copy stuff over when it can't see it as a removable disk? –  bcmcfc Dec 19 '10 at 17:12
    
Hopefully when you install the official drivers it will show up. Make sure you click the notification on your phone (if it comes up) to dismount storage so that the computer can access it. Final thing to do is make sure that the ExtSD didn't get dislodged, I'd take it out and put it back in the slot again. If you have a card reader you can also just take it out and use it in there instead of through the phone. –  Matthew Read Dec 19 '10 at 17:32
