Ext Hard Disk not recognized in File Mgr

By WindowsXP User ·
I'm using Windows XP Professional and I have an External Hard Disk connected to my computer via a USB port that I back files up to. It's been working for months and all of a sudden the External Hard Disk is not being recognized in File Manager. I do see it in the Device Manager. I noticed that on a similar post a few days ago someone recommended that you manually assign a drive letter to the item not being recognized but I can't figure our how to assign a drive letter. Anyone know how to do that?

Right click on My Computer and select Manage. Select Disk Management. On the right side of the screen find your hard disk. It will be labeled as Removable Storage. Right click on it and select the option to Change Drive Letters and Paths.

I too have an external hard drive in an Ultra case. Originally I used the USB connection and I had all kinds of problems. thankfully it also had a firewire connection. I tried that and not a single problem since. Try the firewire if you have it, if not unplug the USB and plug it back in that often refinds the hard drive.

Ok, i know the problem is being caused by the Logical Disk Manager Administrative service and possibly the logical Disk Manager service not being started or the services might be disabled. to solve the problem, click on the "Start" menu, click the "Run" command, and type in: services.msc , scroll down until you see both these services. right click on each of the services about and select properties, on the general tab, change the startup type to "automatic" and click the start button under the service status. do this for both of the services, and it will fix ur problem.

Thanks for your reply, wilsonfamily04. I set the Logical Disk Manager Administrative service to automatic but the logical Disk Manager service was already set to automatic. Unfortunately it didn't resolve the problem (I tried rebooting and uninstalling/reinstalling just in case after the change).

Any other ideas?

By the way, that was an excellent walk-through :-)

Thanks!

When you see the drive in Device Manager is it showing as both Formatted and Healthy?

If you have recently applied any MS Patches you may need to do the following so that USB Devices can be recognised and used again.

Turn off the computer once it's off unplug it from the mains for about 1 minute and then plug back in and reboot. If your problem is related to USB Ports not working correctly this should cure your problem.

Apparently one of the recent Security Patches has caused a problem with USB Ports and isn't allowing them to be access correctly. The above is a Solution from MS to fix the problem.

Any solutions found?

I have the same problem, and tried all solutions, with no luck.
Did you find a solution for your problem? Disk was working fine for months and all of a sudden it disappeared. It is important to notice that whenever I plug in the disk via USB port, the computer plays a sound, but still you cannot see the drive.
