- TITLE :INF: Disk Administrator Displays Blank Boxes for Drives
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:

- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1

-
- Disk Administrator records registry information about the disks
- attached to the system; this information contains drive letter
- assignments and fault tolerance data on volume sets (whether striped,
- mirrored, or striped with parity).
-
- Disk Administrator only displays blank boxes for disks which the
- system believes to be physically present but which Disk Administrator
- cannot access. Typically, this means disks that were present when the
- system started (booted), but have since become inaccessible. A disk
- may become inaccessible because it was powered off, or because it no
- longer responds to the hard disk driver.
-
- If a disk is powered off before the system is booted, Disk
- Administrator does not display a box for it. However, it still retains
- the registry information for that disk, in case it ever becomes
- available again. If the user deletes a volume set (created for fault
- tolerance) that includes partitions on a disk that is not present,
- Disk Administrator updates the Registry information for that disk to
- reflect the fact that volume set no longer exists.
-
- If you run Disk Administrator and do not see as many disks as you
- expect, check to make sure that all your disks are powered on. If it
- displays a blank box for a disk, that disk has probably become
- inaccessible since the system booted; if it does not display a box for
- a disk, the disk was probably not present when the system booted.
