Data recovery for David M. Michael Allen Company Westport, CT USA
Drive is NOT visible in BIOS. The first problem was that the drive failed to boot with a message that the NTLR was missing (or something like that). I then bought a new drive and installed a new OS on that drive (hoping to read this drive as a slave). I do not believe that any data has been written to the old drive since the drive's initial failure to boot. But now when I start the PC, whether I use a cable select or master/slave configuration for the two drives (old/failed and new), the BIOS reports a hard drive failure on this old drive, and the OS does not see the drive at all. The new drive works fine, suggesting that the problem is definitely with the drive, not the PC or controller.
Thank you, David M.
