WINCHESTER SUPPLEMENT
The PREP Utility
The surface of the Winchester disk must be initialized before
you can use it in a system. This is similar to the FORMAT
command and procedure discussed in the Z-100 Series User's
Manual, except that typical operating system information
(headers, labels, boot code and directories) for a specific sys-
tem is not written onto the disk. In addition, PREP will test
the surface and set up standard partitions. Two are set up
— approximately equal in size — so it is not necessary to
run the PART utility unless you want to use some other parti-
tioning arrangement. Also, the disk will normally have been
prepared at the factory as part of the final testing procedure,
so you should not need to use PREP.
You need to be aware that while PREP does test the surface
of the disk for retention of data, it will also destroy any data
that you have recorded on the Winchester disk system. If you
do not want to destroy the data on your disk, but still want
to test the disk for data retention capabilities, you may run
the VERIFY utility. This utility does not destroy the current
data and partitions that are set up on your Winchester disk,
but it does test for and flag those sectors that are bad so
that they can be "locked out" later. See "The VERIFY Utility"
for a discussion of this process.
Before you can run the PREP utility, you must install a jumper
on the Winchester disk controller card in your Desktop Com-
puter. If the jumper is not installed, your Winchester disk can-
not be accidentally initialized. Therefore, the jumper (not in-
stalled) acts as a safety feature for any files that may be on
the disk. If you wish to run PREP, refer to Appendix B (at
the back of this Supplement) to install or remove the jumper.
