This is the error that comes back when the software outputs the command to the 
drive to do something.  The 1 in the 0x51 is the bit that says this command 
has an error, the 5 just says the drive is ready to accept another command 
(ignore the text the SeekComplete is wrong).

When the error bit is set, the software should go and read the error value ...

which should be here.  The 5 is the 0x50 is the "sense key" a value returned 
by the drive to say what is wrong, but it is supposed to be command dependant 
but I don't know what the command is, and I can't find any details in the 
spec for the sense value even if I did.

This just repeats the same error.
