LIF CHK
Verifies that the disk inserted in the specified drive is fully readable by the LIF program. This serves two
functions: first, to verify that the disk has no bad sectors (to minimize the possibility of corrupted data),
and second, to verify that possible spared tracks on the disk will not interfere with the disk’s usage on the
PC’s internal disk drives.
Syntax
LIF CHK <d>: [/U] [/T] [/A] [/W]
or
LIF CHECK <d>: [/U] [/T] [/A] [/W]
Options
The default mode (no option) reads one sector on every track and displays the head
and track number.
<d>: The drive specifier, e.g., 702: or 70201: for an external drive;
A: or B: for an internal drive. All LIF files require a drive specifier.
/U Show usage information for this command.
/T Terse, do not show the Head and Track numbers as each track is read. This can
decrease the verify time by up to 50%.
/A Read every sector on each track instead of just one sector on each track. This is
useful if you believe that the disk has possible media problems (not useful for
additional checking for spared tracks). This can increase the verify time by up to
50%.
/W Wait for keyboard prompt before and after performing operation. This is useful for
a PC with only two disk drives; you can swap out the disk with the LIF.EXE
program to insert a LIF or DOS disk.
Example
LIF CHK 702: /A
Discussion
HP spared tracks on an HP 9122 or HP 9127 disk may not be readable on the internal drive because the
spared track may actually reside on a different side (head) of the disk and the PC BIOS may not be
capable of finding it. This program verifies that each track can be read by the internal drive.
