Hardware diagnostic tools? Interrupts?

[Tom Horsley]

Check the SSD manufacturer's site to see if there is new
SSD firmware available. Also check the BIOS settings to
make sure there isn't something silly going on like the
BIOS defaulting to running the sata interfaces in some
emulated IDE mode.

My corsair SSD drive had lots of warnings on various web
sites about this sort of thing. Apparently it is very picky
about the way the interface drives it.
