Does anyone know where I can get the software to do the low level formatting
of a 40 meg Segate ST251N hard drive? I also need a device driver which will
talk to this drive once formatted. I understand CMS has a device driver but
they are unwilling to part with it except when you buy a drive. I'm not
sure but I think that they only use the low level formatter in house to 
format their drives bofore shipping.

A little background:
        Drive will be used as an internal drive in a Mac II.
        The drive is from a previous project, thus I'm tring to reuse
                money already spent instead of buying yet a second drive.
        When the SCSI formatting program which came with the Mac II is run
                it does not find the Segate drive connectted to the system.
		(Even though I can feel the heads moving during the search for 
		a valid drive.)
                Segate tells me this is because no low level formatting
                has been done (Ie: a low level formating which writes the
                signature ID in physical block 0)

If I can't get some software to solve the problem then I will look at writting 
my own software.  I am not a complete novice at the black art of device driver
writting as I have written some device drivers for Unix. What would help
though is any information reguarding just what the low level formatting is and
an example mac SE or II hard disk driver.

Thanx in advance to all who post replies or e-mail directly.

        don.
