Corrupted FAT32 CF Card

#1 Post by Panayiotis3624 » 03 May 2016, 23:54

I use a 64GB on my Photo/Video Camera.
When I plugged it onto my Microsoft Surface Tablet, it corrupted it.
(Damn, this is the 2nd time this tablet corrupts USB sticks or Cards - Lesson learned)

Windows asks to format the card. Disk Manager sees it as 31MB.
The card appears as 31MB on TestDisk.

Is there a way to restore FAT32 filesystem without loosing card content ?

Can you post the testdisk.log file ?
Choose the PhysicalDrive, not a drive letter (ie. E:)

Hello

Thanks for your reply.
I've been very busy the last two days and wasnt able to deal with my problem.
This morning I plugged my Card and there was a Windows 10 notification that there is a problem with Drive G: and asked for authorization to repair it.
I risked and pressed YES.
To my surprise, the disk was fixed, I was able to browse the content.
I prayed to God!
I started copying the files ... when suddenly we returned exactly to the previous state.

I created a log file, as per your suggestion, however I cant upload it due to extension ???
This is what I get when I attempt to do so.

I restarted the computer and card is readable now.
But I fear to do anything :(
I plugged a harddrive in order to rescue 36GB of very valuable information (Video Rushes).
I use Windows Explorer to copy ... process begins but it interrupts.
Card goes to RAW 31mb
:(

After many reset and reboot, I took advantage of the short healthy period and wrote a new Boot Sector
although I am not certain if this is a proper measure.
Then again, reset and reboot to copy some files until the card goes RAW again.
Some files are 4GB each and I dont think that I will have enough time to collect them
:(

I spent 24 hours trying to fix the BootSector with no luck.
List doesnt show any files.
I wonder if I am done and there is no rescue.
Anyone knows ?

With a lot of patience, I managed to rescued valued content.
Though I formated the card in the camera, it turns RAW and 31MB.
Its fragile. I havent found a way to turn it into reliable card yet :(
Still fighting :(

Contact the manufacturer of the card for a replacement. If it is a good brand they will do it without question.
