SD card shows "No partition found or selected for recovery" on TestDisk

#1 Post by testrun »

Hello,

Recently i was shooting photos with my Canon DSLR. After stupidly (i think this was the factor, since its first time it happens in like a decade of trouble free use) putting a couple video files from a laptop in the same card i was using to shoot photos, i could shoot normally for about 30 minutes, then camera froze while saving a pic, then after restart it couldnt open the card anymore and stated it needed reformatting. When putting the card on a laptop it says the same message, need to format.

Tried Photorec, but it couldnt find anything. Then tried TestDisk, which at first states "No partition found or selected for recovery", then "Partition sector doesn't have the endmark 0xAA55", neither Quick nor Deeper search get anything beyond these two messages. Trying to access Advanced states "No partition available".

Disk //./PhysicalDrive1 - 62 GB / 58 GiB - CHS 7650 255 63

According to what im reading, file system could have gotten corrupted and rebuilding MBR could fix things, but im really not sure at this point, might break the card even further
Hopefully theres something i can do, itd really be terrible news if these pics are lost.

Did you run Photorec as admin?
As Photorec fails to find content, I have to assume that your SD-card is broken.
Please contact a professional recovery lab.

This posting is nicely written as if it was created by an AI tool, but it is logical nonsense!

If someone has already run PhotoRec before running the standard procedure and PhotoRec does not find files, rescue efforts are useless because PhotoRec does find even Canon raw formats (.CR2 and .CR3). A destroyed MBR does not prevent PhotoRec from finding files.
