[SunHELP] anyone gotten a 73gig drive to work with am ultra?

[Arthur Wouk]

i purchased a 73gig sca hard drive in a sun 611 case some time ago,
and tried to attach it to a 'new' ultra-1. it was not recognized, no
matter what i tried. i eventually took the drive, attached a 50pin to
sca adapter, and put it on a sparc2 which is very reliable, and besides
has sformat working on it. it was attached at scsi station 0.

this time the machine recognizes the drive, but the drive
does not respond to sense signals.

so how large a drive (and which ones) will work with  sun machines?
