I just wanted to post a general notice of something that some may already be familiar with concerning running SeaTools for DOS on hard drives.
It seems that there may be a problem when certain system BIOSes are set for AHCI.
As noted in the link above...the simple solution is to change Bios settings to reflect the IDE option and the recognition problem is solved.
, thanks to dc3 for bringing this to my attention .
And, of course, there are other hard drive diagnostics that will also be considered reliable should you just decide not to use SeaTools for DOS.
