Drive Letter disappears when re-booted

By rotocron ·
I have an NT 4.0 workstation machine w/ SP5. The machine has 3, 9g disks, all Ultra SCSI 2 Cheetah LVD's. All partitions are NTFS. The first disk has two partitions, number one is a 4g boot and system partition, the second 5g is just a data partition. The second and third physical disks are just one big 9g partition (RAID0). The first disk is running on the controller built into the MB. The second and third disks are running on a AAA-131U2 controller (RAID), and is striped and partitionedfor the entire 18g. I have Adaptec's CI/O software (Build 10) installed and working fine, and the OS see's the 'disk'. The problem is that NT will not keep the drive letter. After partitioning and formatting with NT's Disk Administrator, every time I reboot the machine, the drive letter dis-appears. All I have to do is "Assign Drive Letter" again, and the data is still there and I'm off and running like nothing happened. What's going on?

HMMM... seems simplistic but are you using the "Commit Changes now" option prior to closing the NT Disk admin?

Try this tip from JSI Inc: "Tip 1061 ? SCSI device does not retain drive letter assigned in Disk Administrator."

The link is: http://www.jsiinc.com/TIP1000/rh1061.htm

This sounds like a problem with your SCSI Controller drivers. Try downloading the newest version of both drivers (the one on yout mainboard as well as the external one) and installing those new drivers.

If answer 1 is not correct the nexr question is do you have any ide devices or is this system a CompaQ?

We were solving similar problem with COMPAQ
ProLiant 2500. After we applied the proper SoftPaq {sorry, I do not remember the number} the problem was gone.
