I just aquired a 60gb drive that I'd like to use to replace the C drive
in a win98 system. I no longer have a working OEM CD, and a generic
win98 CD would not have the proper drivers. I'm thinking of keeping the
dying 20gb drive as a backup.

Is it possible to temporarily disconnect the ZIP drive I haven't used in
over a year and install the new drive as a slave, make a 20gb primary
partition, and make the remaining space an extended partition on the new
drive. Then use the old MS-DOS command DISKCOPY to copy the C drive to
the primary partition on the new drive?

If I then hook up the new drive as the C drive, would I expect things to
work perfectly?

I know, the obvious answer is to hook things up with the new drive as a
slave, but I have all four IDE channels tied up, so in order to hook it
up I have to take something out. I'm not even sure if I still have the
old panels for the bays, and I'd lose the functionality of that device.
