Your IDE is being addressed as a SCSI device (hence the *s*da designator).
The hdparm utility won't work on SCSI style devices.  I know there is an
sdparm but I'm not sure if it is needed here.   Have you tried some hdparm
performance tests (which I think work) to see what the stats are on the
drives to see if they are reasonable?
