I go to the BIOS, set the controller to IDE and boot from the USB drive.

I create a bootable CD with Seatools for DOS, set the controller in the BIOS to IDE mode and boot from it and the CD either hangs silently, or hangs with an “invalid opcode” error.įollowing the instructions here, I create a bootable USB drive with Seatools for DOS. I installed Seatools for Windows, and it detects all the HDs in my system except the boot drive, which is the one I want to check. I have a Gigabyte P55-USB3 motherboard, and that I have the Intel controller set to RAID mode: I’d like to use Seatools to do a through test of the drive before replacing it, but the problem is that I can't get it to work. I have a Seagate 1TB HD set up as my boot drive, and according to its SMART parameters, it’s starting to fail: the “Reallocated sectors count” is at 458 (and has been increasing for the last months), while “Current pending sectors” and “Uncorrectable sectors” have recently jumped from 0 to 3.
