Does anyone know if track 0 cylinder 0 on a winchester disk drive has any
significance?

I'm asking this because we have a tool (written in pascal86) to run on
a 310 box that formats brand new hard disks.
When a new winni is delivered the manufacturer supplies a listing of
all the bad tracks for that disk, and the tool we use takes this bad
track info and stores it in the relevant place on the disk.

The problem we had with one disk was that the manufacturer said track 0
cylinder 0 was a bad track - so we enter it via our tool.
When a 'rqa$get$file$status' bios system call is issued from within
pascal86 the 'dev$name' return parameter (the name of the hard disk)
is blank.
However, if the track 0 cylinder 0 info is ignored from the list then
the device name is accessible.

Any ideas would be welcome for this not-so-urgent problem.
