Seagate USB

#1 Post by sbtm77 » 26 Feb 2016, 09:20

Hi Everyone,

I have an external Seagate USB drive where I have important office stuff. Plugged it in tonight only to get the drive is not formatted message. I had used it the night before and it was working fine. In fact, used it to retrieve some files off of it.

Testdisk crashes when I list the files and also give me a message that the size of the disk is too small!

To cut the story short, I am attaching the log file!

There are CRC errors, it means the disk contains bad sectors. You should clone the disk to a new empty disk (can be bigger) using ddrescue from a Linux LIveCD/USB. Once it's done, remove the original disk and try to access your data on the clone.
Here is an old tutorial about ddrescue https://www.cgsecurity.org/wiki/Damaged_Hard_Disk
