USB Hard drive not showing up in 'my computer'

  Lord Justice 11:13 22 May 2007

Hello all,

I have a USB hard drive that I need to use for back up purposes.

However it does not show up in my computer when connected. I know it is switched on etc and it is showing in device manager but I cannot see it in my computer in order for me to put files onto it.

How can I find out the drive letter? So I may use the command line to format it?

If you turn the HD off, and with the computer running plug in the USB lead and power the HD up, what happens? Do you get activity on the task bar showing that a 'mass storage device' has been detected etc. ?

yes it is detected, but not showing in my computer

I can't remember exactly how you do this, you right click on the My Computer icon and goto Manage I think and then click on Disk Management but I can't recall what you do after that, there is some sort of option to enable the drive to be seen but I cannot recall where it is.

Hopefully someone else will give you the ending to what to do.

There will be an option in device manager to disable the drive, which would obviously need to be changed if so, but I think you would see a red cross against entry in device manager for it if this were so. Does the USB icon in the system tray report that it 'cannot find driver' for the device?

In Device Manager, the external drive should be listed in Disk Drives.

Highlight it>right click>and then click on Update Driver.

I have seen a similar problem before. There was a conflict with two drives trying to use the same drive letter. If you go into Disk Management and Right Click on the USB device you wil get an option to change the drive letter. Change it to a lettr which is not used by any other drive (including network drives).

Right click My Computer\Manage\Disc Management Set the drive as active and format it

I knew it was something like that woodchip but I just couldn't remember what to do.
