Hello, All! I have four HDs IDE in my Pentium 200 machine and other drives attached
in
AHA2940AU SCSI. All drives run nice under Warp 4.0 but the Fdisk feature of OS/2
can't
work in the HDs plugged in the second IDE port onboard (second master & second
slave).
Also Partition Magic under OS/2 not working in this HDs. But, Fdisk and Partition
Magic
see the four HDs perfectly and the Warp 4.0 work perfectly in the four IDE HDs.
How can
I do to solve this problem? Have any computer guru rather than me here to help
me now
about this? I thank in advance!!!
You have 3 IDE ports:
IDE 0 - IRQ 14 - must be the primary IDE port on the motherboard. It has 2 Western
Digital -3.2 gig hard drives.
IDE 1 - IRQ 15 - must be the secondary IDE port. It has two more hard drives, 1
Quantum (size unknown) and the other one (brand and size unknown).
IDE 2 - IRQ 10 - has another unknown hard drive and an ATAPI IDE CD-ROM. Port 2
must be an IDE add-in card since it has an assigned IRQ of 10.
I could be wrong on this, but it has always been my understanding
that you can't have more than 4 IDE devices on a motherboard. That's why SCSI is
advantageous because you can add up to 16 devices off one SCSI control card. However,
you say it has worked for you except for being able to fdisk the 2 hard drives on
the secondary ide port.
Here is my suggestion. Disconnect the ATAPI and other miscellaneous hard drive
from the add-in IDE card. Then pull the card out of the machine. Data on the hard
drive that has been disconnected won't be lost. Now the bios and OS/2 won't recognize
the additional IDE port.
Now try Fdisk on the two hard drives. Hopefully it will work. If it does, then make
your modifications. When through, you can always add the card back and reconnect
the two other devices since you have indicated they all worked.
