15 After diagnosing the problem with the help of Alan Stern and Matthew Dharm, the
16 conclusion was that the sector size translation must be triggered by some
17 interaction between the drive and the BIOS. The test I performed to determine
18 this was:
19
20 - unplug the drive,
21 - turn on the computer,
22 - plug the drive in once GRUB has started, and
23 - boot the kernel,
24
25 after which the drive worked fine. So this does not seem to be anything that
26 can be fixed in the kernel. Perhaps if I had an EFI compatible mainboard, I
27 wouldn't be seeing this problem, but I don't, so I can't even try it out :-/ .
