Have you tried a low-level formatting utility? (Or, a 'destructive'
diagnostic -- one that will do write/read tests across the whole disk --
a great way to vaporize things. Compaq's diags have a 'destructive'
option if you have access to a Compaq system w/SCSI.)
Just a footnote, having dealt with SDI products, it's not the "Novell"
formatting, it's proprietary work that SDI does so that the drives will
work with SDIs controllers (BusLogic boards w/SDI proprietary BIOS) and
SDI drivers under NetWare -- it's supposed to yeild a performance
increase. What all this 'proprietary' work does get you is a price
increase, and forces you to use SDI-prepared drives when you use an SDI
controller under NetWare (SDI controllers will work fine under
Linux with the BusLogic driver and not show any preference for whose
drives you use).
