[comp.sys.ibm.pc] Jumpers question

tkoppel@isis.UUCP (Ted Koppel) (01/23/89)

The following question arose as I was trying to install a second hard
drive (20mb) in my XT.

There is a row of eight (8) pairs of pins on the board.  When I had
one 20mb disk drive there were two jumped pairs, #3 and #4 (counting
from 1, not counting from 0).  When I added a scond 20mb drive, the
system sees the additional drive (D:) and that it has 21 million bytes
available, but when I write to it, I get lots and lots of unlinked
clusters.  (i.e. mucho bad data!!)

The drive is a Seagate 238 (which I know is an RLL but I am using as]
an MFM drive which means that I only get 20meg instead of 30 meg);
the controller card is a Western Digital WD 1002S-WX2.

Ideas?
