IBM SCSI drives not showing in Disk Management

[Lester Brook]

I have recently installed a Qlogic ISP1020 SCSI adaptor on
which I have been running a 68 pin Seagate ST34573W SCSI
Disk, a 68 pin Quantum Atlas IV 9 WLS SCSI Disk, and a 50
Pin Seagate STT8000N SCSI Sequential Tape Drive with no
problems (all second hand equipment).

Today I have installed 3 x second hand 68 pin IBM DFHS
2.2GB SCSI-2 Fast/Wide Disks. These disks detect on the
SCSI card during the BIOS install and show their SCSI and
drive IDs, they appear in the Device Manager as IBMAS400
DFHSS2W Disk Devices with no problems but when I go to the
Disk Management to create and/or remove partitions on them
they are not displayed there...

When the Disk Manangement is being opened for the first
time after boot up (or after a period of no use) each
drive can be heard starting up (all 5 SCSI drives) however
the list give Disk 0 as my first IDE drive, Disk 1 as my
second IDE drive, no disk 2 is displayed, disk 3 is my
seagate SCSI disk, disk 4 is my Quantum SCSI disk and
there is no disk 5 or 6.

I have tried different SCSI IDs, removing drives, having
only one of the IBM SCSI drives on the 68pin chain, I've
tried different termination settings all to no avail.

Can anyone please let me know what the problem is and what
I can do about it?

Thanks

- Lester.

See "SCSI drive almost recognized..." I had a simliar problem to yours but Disk Management worked. This doesn't help you much, however, I can commiserate with you. Until I learned about Disk Management on these pages I was out in the cold.

I had tried to format the new (old) disk I had with Partition Magic and got nowhere. There is something subtle going on in Win2K regarding the recognition of SCSI drives. A couple of days ago, I installed another IBM DeskStar SCSI drive of the same family (a 39130 I believe it was -- a 9gb version of the 4gb drive that gave me trouble) and Win2K + Adaptec 2940UW had no problem recognizing and access it. This was the 5th hard drive on the SCSI bus.

When I added the 6th drive just two days ago (a 34560 -- which is a 4gb version of the 39130), Win2k + Adaptec 2940UW found the drive but it was not accessible at the command line or in My Computer. The Device Manager found the drive just fine. It reported "No problems."

It's shard to see what the problem is.

On this 6th drive, once I started Disk Management, it found the new drive and I was able to format it.

This must be some qirk in Disk Management with respect to SCSI drives. Wouldn't surprize me. Microsoft is probably putting miminal effort into accommodating SCSI hardware -- in Win@k no less -- at this time.
