[comp.sys.sgi] 4D/20 tape requirements

dunlap@bombadl.SGI.COM (D. Christopher Dunlap) (10/11/88)

The Personal Iris uses 150Mb SCSI tape drives. These tape drives
require higher density cartridge tapes than previous systems. Silicon
Graphics recommends 3M's DC600XTD tape cartridge. This tape has the
folowing specifications:

	600ft. long
	extra track density
	12,500 ftpi
	550 oersted

If you use a tape other than this 3M model, make sure it meets or
exceeds all these specifications.

Several customers have called us with complaints of "Mode Sense
Protocol" errors. These are caused by trying to create a tape on  a
cartridge that does not meet the ratings above.

If you get these errors on a tape cartridge that meets or exceeds the
above specifications, please call the Silicon Graphics Geometry
Hotline immediately at (800) 345-0222.
