Specs: Windows XP
Hi, I'm running WinXP Pro SP3. I keep my My Documents folder on a second, slaved HD. After a quick electrical glitch the drive lost its letter and I can no longer see it in explorer. I can see it still in both Disk Manager and Device Manager. Here is the info I can get from those 2 places:

Device Manager
Disk: Disk1
Type: Basic
Status: Online
Partition Style: Master Boot Record (MBR)
Capacity: 305243 MB
Unallocated Space: 0 M
Reserved Space: 0 M
Volume: Documents

From Disk Mgr.
298.09 GB
Primary Partition
Healthy (EISA Configuration)

When I right-click on the drive in Disk Mgr. the only option is Help, which is of no help.

I'm kind of stumped here. I do back up every couple of nights but I would really rather not start reformatting, etc.

Any ideas out there?

And you have admin privileges?

Check that you still have permissions to do that task.

Are you playing with me or do you have something to contribute? I responded in good faith to your question and you just asked it again.

A 'EISA Configuration' is normaly the recovery partition on name brand comps. It would seem that the Master Partition Table is now corrupt. Can try 'testdisk' (do a web search) to fix problem, be sure to read the How-To use first. Or if you have a hdd editor program, you can manually edit MPT. Sector Editor

MS's Dskprobe part of W2k/XP resource kit.

If you have a live linux cd and know how to use it, that can be used.

Did the hdd have only 1 partition ? That would make it easier.

Thank you for your answer. Strange that it got that EISA config as it was just an internal hdd that I bought and threw into an enclosure and connected by firewire. It worked properly for about 2 years and, as I mentioned, suddenly went *blip* when the lights went out for a second. I have a surge surpressor that is attached to the main electric panel in my house, which is far more sensitive than anything you can buy that plugs into the wall, and which protects the entire house from surges. I guess, though, it's time for a battery backup system prevent the scrambling that sometimes happens with a sudden loss of power.

I'll give your suggestion a whirl and will let you know how things go.

Thanks again.

How did you get the information you state came from Device Manager?

Hi OtheHill.

No problem.

1. Click Start-->Run
2. Type compmgmt.msc in the box and then click the OK button
3. In the window that opens, along the left side, find and click on Device Manager
4. In the right-hand pane find Disk Drives and click on the little plus sign to the left of it
5. Locate the drive you want info on and double-click on it
6. In the new window that opens find and click on the tab along the top that says Volumes
7. Find and click on the Populate button near the bottom of the window

That's all there is to it.

Note: If, for some reason the management snap-in is not set up on your computer you can substitute the following for steps 1 - 3: Go to Start then right click My Computer and left click properties. Click the Hardware tab then click the Device Manager button

Hope this is helpful to you.

I can't believe I never noticed the populate button. Guess you are never too old to learn.

As TopFarmer stated, testdisk MAY correct the glitch.
