I'm not able to update the firmware on a Seagate ST3500620AS hard drive, neither with the Windows update tool nor the bootable CD (available on this page : http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207951) These tools are unable to find the hard drive (it displays scanning SATA disk... 0 disks detected).
But this hard drive is detected by the BIOS and by Hirens Boot CD.
The reason I want to update the hard drive firmware is because it doesn't work properly. I'm unable to mount it in Windows 7, in Hiren Boot CD mini-XP it works sometime but I'm not able to make a backup of this HDD because I'm always getting errors when I'm trying to do so.
Seatools is unable to detect this hard drive.
