[comp.sys.ibm.pc] Hard Drive Conflict

jwbirdsa@phoenix.Princeton.EDU (James Webster Birdsall) (03/08/89)

   I have an old 10 Meg Plus Hardcard in my PC XT. I recently acquired a
Seagate 238R with WD controller 1002A-27X. They worked fine for a while;
then I got persistent write errors on the Seagate when I tried to put
more than 10 megs on it. 
   Following a call to technical support, I did a low-level format and,
lo and behold, the Seagate only formatted to 305 cylinders (approx 10
megs)! 
   Today, as a last desperate maneuver, I removed the Hardcard and tried
the low-level format again. 939 cylinders, this time. The problem
appears to be that the system gets confused between the two drives. So
I divided the Seagate into a bunch of logical drives 10 megs or less
apiece. Everything seemed to be working fine; however, when I boot from
the Seagate, I only get 305 cylinders again! It will only recognize two
of the four logical drives and will only write to one of them -- the
other shows the same write error as I had originally. As long as I boot
from the floppy, everything works fine. All the logical drives are alive
and well.
   Anybody have any idea what difference booting from the floppy makes?
Or any other suggestions?

[Technical details: the Seagate is drive c: (and e:, f:, g:); the 
Hardcard is drive d:. I cannot use the Hardcard as the first HD and
the Seagate as the second because then I get ROM overlap, which makes my
machine very unhappy. I have also tried setting both as the first drive
and setting both as the second drive (hey, I was running out of ideas)
-- one of these stunts produced ROM overlap again, the other produced a
controller error (1701).
   The WD controller is RLL, as is the controller built in to the
Hardcard.]

   Thanks a lot...
