      Try rebooting the computer without any USB devices attached. Then plug in the USB drive, right click on My Computer, select manage, and then click ?Disk Management.? If the drive is not present in the Disk Management window or if you are not able to access it, then the drive may have failed. In this window you should see all of your connected physical drives, their format, if they are healthy, and the drive letter.
      Change the drive letter of the drive. Right-click on the drive in the list, and from the resulting menu select “Change Drive Letters and Paths”
      Click on Change so you can change the drive letter. Click Change.
      Select a new drive letter from the drop down list, preferably the one that is not normally used for this drive. EG: U:
      Click Yes on the confirmation screen

      To disable power management on the USB hub:
      1. Right-click My Computer, click Properties, click the Hardware tab, and then click Device Manager.
      2. Double-click Universal Serial Bus controllers to expand it, right-click USB Root Hub, and then click Properties.
      3. Click the Power Management tab.
      4. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.

      If the above is of no help then

      Inspect all the parts of the external Driver’s Enclosure and Leads. If there is any damage to a Lead or case replace the affected parts.

      AS this has previously worked I’m assuming that you have a 2.5 Inch External Drive mounted in some form of USB Enclosure. What you need to do here is plug the USB Lead into the NB’s Mother Board not a USB Expander or other USB Socket and if you have a Y Cable with 2 USB Plugs make sure both are plugged into the NB. The second one is to provide more Power to run the Drive. If you have a Y Cable look at the USB Plugs the one furthest away from the HDD End is for [b]Power Only not Data.[/b] So if you have been plugging this in the External Drive can not appear. Also as modern NB’s have very low power at the USB Sockets you need to plug in both USB Plugs to the M’Board or there isn’t enough Power available to run the drive reliably. If you don’t have a USB Y Cable you need a external Power Supply or a Powered USB Hub to provide enough power to run the External Drive.

      If you have a Plug Pack that plugs into the USB Case make sure that it’s actually plugged into the mains and that it’s working sometimes these Plug Packs fail and then there is no power to run the HDD.

      If you constantly leave the External HDD plugged in and running it’s most likely failed as these get hot and they die much sooner than they would otherwise do. They are also subject to vibrations and other bumps which can damage the drives.

      Of course it would be better if we actually knew what was involved here so that we can answer your question exactly and not have to give a Generic Answer to cover all possible configurations or hardware.
