Hi
First,
DON`T low level format the hard drive....
You'll break it.
Have a look at some second-hand websites for the disks, (£5 at most) , like
amibench...
(hum, i just noticed someone giving away a free 1200 there)
Oh well..
And when you do get them you'll have to partition the HD into a few partitions (depending on the OS version, with the limiting size of 2Gb)
Then format and install
Easy. :-)
