#	@(#)disktab	8.1 (Berkeley) 7/23/93
#
# Disk geometry and partition layout tables. 
# Key:
#	ty	type of disk
#	ns	#sectors/track
#	nt	#tracks/cylinder
#	nc	#cylinders/disk
#	rm	rpm, 3600 default
#	se	sector size, 512 default
#	sf	supports bad144-style bad sector forwarding
#	so	partition offsets in sectors
#	p[a-h]	partition sizes in sectors
#	b[a-h]	partition block sizes in bytes
#	f[a-h]	partition fragment sizes in bytes
#
# All partition sizes contain space
# for bad sector tables unless the
# device drivers fail to support this.
#
# Entries may also be used for other compatible drives
# with the same geometry.
