I've been trying to research what I'm doing a good chunk of the night and feel like I've gotten nowhere. I have a samsung s5 with a 64gb sandisk sd card. The sd card recently started to have random photos show black and say they are corrupted. Now the entire card is corrupted and won't read. When inserted in the computer, it prompts to format the disk. I tried disk manager and found that the drive is raw data. Teskdisk returned a message that the "partition sector doesn't have the endmark 0xAA55" then doesn't find a partition. Photorec shows the drive but only shows it as having 8MB. When I try to recover files, it recovers no files. Thank you for any help and sorry I can't brain today

The disk capacity is wrong, it looks like an electronic problem. Software can not help in this case.
If you really need to recover your data, you need to contact a data recovery company.

Thank you
