You usually want to use modprobe rather than insmod, by the way. It
takes care of module dependencies automatically, that way. (modprobe is
a wrapper around insmod.)

It's possible that looking at the end of /var/log/dmesg, around that
time, could be enlightening. If you see nothing about a hard drive
there, then either it's a hardware problem (unlikely), or something like
your suspicion about a weird drive incompatibility might apply -- in
which case it'd be handy to borrow a second SATA drive and cross-check.

No, they don't.

Then you already have everything *I* had to offer on that subject, and a
bit more. ;-> Sorry to hear about the problem.
