Trying to recover lost pictures from PNY SD card

#1 Post by w18918 » 28 Feb 2013, 16:36

I've got a PNY PRO-ELITE 16GB SD card that has worked well with my Nikon D5100 camera for about 3 months. Just recently however, my camera is unable to detect the SD card. I've got a couple weeks worth of photos that I didn't get backed up, which I would like to recover. On my Windows 7 PC with built in SD card reader, I can access the card, but I get this error:

You need to format the disk in drive D: before you can use it.
Do you want to format?


I have not reformatted the SD card yet, but I have tried TestDisk and PhotoRec without much success.

TestDisk displays message:

Partition sector doesn't have the endmark 0xAA55

Then I do a Quick Search to Analyse cylinder and Deeper Search, but I just get the message:

No partition found or selected for recovery

I also tried PhotoRec, but it found 0 files.

Any other suggestions to try? I've tried some other different data recovery software applications, but having no luck. Should I reformat the SD card? Would doing this help or make the file recovery process more difficult? Thanks,

Thai

Please repeat your diagnose.
Don't confirm at "Analyse" but "Advanced" and "Boot".
Run "Rebuild BS"
Check the menu List and let me know, did you see your files or an error message.
If no partition is displayed, repeat the diagnose using partition table type "None".
If your partition appears in the menu Advanced as unknown, use type to change the file system.
Normally SD Cards are FAT32 preformatted,
Using partition type intel, you can enter the code 0c for FAT32.
Using partition table type "None", you can select FAT32 directly within the menu "Type".

Also copy and paste the content of your testdisk.log.

Fiona,

Thanks for taking the time to help debug this problem. Below is the content of the TestDisk log. Please let me know what else I can try. Thanks,
