Right. I will give that a go. Does anyone know the following parameters
for the LS120 diskettes?

* End Track (I think these disks have a capacity of 123264 blocks. Can
anyone confirm this? Do I need to double this value for 512 byte sectors?)

* Size Code (I guess we have 512 byte sectors, so the size code is 2. Is
that right for a laser servo diskette?)

* Stretch Factor

* Format Gap

* Final Gap

* Interleave

* Chunk Size

* Biggest Last

* Zero Based - Do I need to set this? If this is set, do I need to
subtract 1 from the End Track number?

* Absolute skew

* Head skew

* Track skew

On the latest version of Debian, my laser servo drives are now mapped to /
dev/sdb, rather than /dev/hdb. Will /dev/sdb accept the instructions to
format from the superformat application?

Mark.

No, but you may be able to read them of a correctly formatted one

Those tools are for floppy disk drives on the floppy disk controller. The
LS120 drive is attached to the IDE controller.
