I would like to install a 2nd hard disk in my plus and would like
to get some recommendations. Preferably I would like a hard disk card
with about 20-30Meg capacity. I want to run UNIX on one disk and
MS-DOS on the other. Has anyone had experience with this? Any
recommendations? My configuration now is the original 20M hard disk
and a 1.2M floppy with 1M of RAM.

We have tried putting a hard card in a 63+ and have had troubles with the hard card controller being incompatible with the resident controller card. On my system I install a 2nd 20 megabit hard disk Because of the percevied problems I purchased a Segate st225 drive, which is the also the same model of the original drive. I wanted to be able to run Unix on part of the first disk, and Dos on the 2nd hard disk. It all works find. I did not have to put any jumpers on the controller card or change any switch settings on the mother board. The 2nd hard disk is controlled by the original controller card, WD 1002s-wx2. The 2nd hard disk came with a WD 1002s-wx2a card, which had its own rom bios on the card. When I first installed the 2nd hard disk and booted up the machine it saw that there were 2 disk but would give me an "invalid drive spec" when I called for a "d" drive. What I finally did was to replace the original controller card with the card that came with the disk, changed the switch setting on the mother board tellint it to use the rom bios on the controller card, and left the original hard drive disconnected, and made the new drive "c" drive. I was then able to format the new drive. I then put the system back to the original state, connected the new drive as "d" drive and it all work! I forgot to mention that the resistor chip must be removed from the "c" drive and left in the "d" drive, also the jumper on the back of the "d" drive must be moved to the 2nd position, instruction for the resistor and jumper came with the drive. By the way I moved the controller card over to the far left and placed a piece of cardboard under the 2nd harddisk held on by rubber bands, and put the 2nd hard disk in the machine, looks and works good.
