Naturally, having been used as a doorstop for some time, it didn't feel like formatting - parm block error of some sort. Funny thing was though, the setup software was the same version of the old siders, just a tad more primitive. Unfortunately, the later software didn't help it any, but for some reason, early this morning it decided to start working. However, it appears that the only usable part is the Prodos section - i can't boot into it, dos doesn't like it, and I can't setup the CPM partition. I gave First Class a call to see if they had a utility to setup it to boot into Prodos, and they refered me to Advance Technical Products in South Carolina. Seems that they make a chip that you replace on the interface card so that you can use it as a Prodos only bootable drive. The price is reasonable - $59.95, software included, but I wonder if this is really necessary. If you can boot off of the drive into Dos, shouldn't it be possible to boot into Prodos just by re-writing the boot track on the Hard Drive? Oh yes - their phone # is 404/441-3322 First Class Peripherals # is 408/752-2482 I should mention that this modification is for the 10 & 20 megs only - First Class supports complete prodos volumes on their larger drives (40 meg & up). > Michael Steele > mikes@ncsuvx.ncsu Chan Wilson kodali@portia.stanford.edu -- it's a full moon - that's the problem....
