I have an old 3.2 gb wd drive like that. It is model number AC23200. Yours
is probably very similar. If your intention is to make it a boot drive, it
must be fdisked and set active as you most likely know. However, if you
already have a booting disk in the system, this drive must be hooked up as
the only drive (disconnect everybody else), connect it as master with no
jumpers on it at all, fdisk, format and sys it from your floppy disk.
Windows fdisk will only allow one "boot active" drive and if it sees another
active drive, it will not allow you to make another one active.
NOTE: Don't forget to prepare your boot floppy disk with fdisk and format on
it.
Once you have the thing fdisked, formatted and set active you can then hook
up your other drives and carry on with what you want to do.
I don't recall if I had dma mode set on it or not (I think I did), but it is
an ata33 drive in any case.
