Backup, backup, backup ;-)
 
You'll need a Real Expert(tm) to help on the ILLEGAL_LENGTH error, but
I've seen UNCORRECTABLE plenty.  Keep in mind that it may cost some time
and energy to find out; apart from a bad disk, could be a bad disk *controller*.

I bought two new HDD's recently because of similar problems, but all of
them are now working fine on a new motherboard :-/

Sorry no help here :-/
