WinXP Pro - Disk Management snap in problem

By d.isaksen ·
I have Windows XP Pro installed on a computer and am having a problem with Disk Management not displaying any of the hard drives installed in the system. I tired running "Diskpart" from DOS and when I ran the "list volume" command, the hard drives were not displayed with it either. Both Disk Management and running "Diskpart" do show the two DVD writers I have installed, but that's it.

The two hard drives that won't display in Disk Management are recognized correctly in the Device Manager, Windows Explorer, defragment utilities, and Windows Explorer, but for some reason not in the Disk Management or by running "Diskpart" in DOS.

I've tried running "SFC /scannow" to make sure the windows files are as they should be, but it did not help. I also tried hunting down references to the issue I'm having, but with no luck. I hope someone here will be able to clue me in to what the problem is and provide an explain of how I might be able to fix it.

all of the motherboard device drivers or updated them. Here is a couple of ways to rescan the drives.

he basic or dynamic disk is not accessible and might have experienced hardware failure, corruption, or I/O errors. The disk's copy of the system's disk configuration database might be corrupted. An error icon appears on disks that display the Unreadable status.

Disks might also display the Unreadable status while they are spinning up or when Disk Management is rescanning all of the disks on the system. In some cases, an unreadable disk has failed and is not recoverable. For dynamic disks, the Unreadable status usually results from corruption or I/O errors on part of the disk, rather than failure of the entire disk.


Using a command line

Open Command Prompt.

At the DISKPART prompt, type:

Value Description
rescan Locates new disks that may have been added to the computer.


To open a command prompt, click Start, point to All Programs, point to Accessories, and then click Command Prompt.
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.
Use Device Manager to scan your computer's hardware for changes. Then, use the DiskPart rescan command if your disk configuration has changed but the changes do not appear in Disk Management. For more information about Device Manager, click Related Topics.
When DiskPart rescans disks, it scans all attached disks for disk configuration changes. It also updates information on removable media, CD-ROM drives, basic volumes, file systems, and drive letters.
Rescanning disks can take several minutes, depending on the number of hardware devices installed.

To troubleshoot this issue, restart the computer or rescan the disk to try and return the disk to Online status. To rescan the disk, open Computer Management, and then click Disk Management. On the Action menu, click Rescan Disks.

For a complete list of disk and volume status descriptions and troubleshooting procedures, see Disk Management Help. In the Disk Management snap-in or Computer Management window, click Help on the Action menu.
