With the Compaq controller I got 300M out of them. With the UltraStor controller I get 330M or 360M depending on how many spare sectors I put on each track. > Is this loss because the cylinder count > cannot top 1024? It's because the mapping only multiplies out to 300M. > In this case, there's no easy way to have a DOS partition > co-exist with your other OS. That's OK.

I wish I could afford 760M of new drives, but at the price I got these for they can't be beat. -- Peter da Silva. <peter@sugar.neosoft.com>. `-_-' Hefur thu fadhmadh ulfinn i dag?
