Hello,

This is my first post over here.
I have a Seagate ST31000520AS drive, the drive spins normal, no weird noises.
Windows asks to format the drive.
I tried with several data recovery programs, but all I get is read errors from start to end.
Is this some kind of firmware problem ?

Thanks in advance !

This isn't a pure "firmware issue". The disk already has problems. It's best to contact a DR specialist for data recovery.
If the data isn't that valuable, research Seagate LED CC online...

Thank you, I have searched on the net, and found some articles and posts about seagate drives having a common issue with BSY state or 0 LBA error.
This disk I'm having is still recognized in the bios and appears with the right name and capacity.
I noticed when recovery software is 'reading' from the disk, the disk is just spinning, but you cannot hear activity as in heads moving.
