Just tried them, those seem to be correct for the 9905 as well.  
Huzzah!  When you get a chance, if you could scan the quick reference 
I'd really appreciate it.  I need the diagnostic codes to change 
internal drive settings... this drive used to be configured for the SCSI 
interface and I need to reconfig it so the Pertec interface works properly.

Thanks again,
Josh
