SKIPTEST [DEVICE] [SAMPLES] [READS] [RS] [RE] [SS] [-H]
SKIPTEST plots how long it takes to read a group of blocks
(defined by READS), then skip a number of blocks (defined by RS
and RE). Negative numbers are allowed in order to see the effect
of head movement backwards and forwards. SS will automatically
be adjusted if the result would mean the head leaving valid disc
area. This test will give you a gauge of head access speed.
DEVICE - the device name of the CD-ROM drive default first
drive
SAMPLES - the number of samples to take at any test point
(default = 1)
READS - the number of CD-ROM blocks to read at any test
point (default = 8)
RS - range start is the first number of blocks to skip
between reads (default = 0 blocks)
RE - range end is the last number of blocks to skip
between reads (default = 30)
SS - start sector for test to begin at (default = 0)
Example default SKIPTEST D 1 8 0 30 0
Read 8 blocks, skip 0 blocks, read 8 blocks starting at 0 then
read 8 blocks, skip 1 block, read 8 blocks starting at 0 then

read 8 blocks, skip 30 blocks, read 8 blocks starting at 0.
