Hi TSG, for some reason, my PC recently has just rejected my external hard drive (Maxtor One Touch). It was recognized normally and worked properly before. I tried to switch from Firewire to USB to see if was there anything wrong with the cable issues, but both seemed useless. Everytime i try to plug it in, my system alerts that "This drive need to be formatted". Althouh i tested with many different computers laptops, my external hard drive works fine. Can anybody help me out with this sisuation because im very helpless now. Thanks TSG very much!!

Have you istaalled or used another external storage device in thatport also...

Have you look in Disk Management to see what it says about it.

Click Start>>right click My Computer>>Manage and then on the left-hand side click on Disk management.

yeah i have 2 different external hard drives (both Western Digital notebook), and they both worked fine. I tried to pluged in all the port (front and behind) but neither of them worked. Notice that I had been used this external hard drive (Maxtor) for awhile, and it just happened like this lately (last month). Is there any wrong with my system or hard drive??

Does the drive work properly connected to another system, or does it get the same error?

First step, Start, Programs, Accessories, System Tools, System Restore. Create a restore point and name it something like "Before USB Fix". This is to bail you out if something goes wrong during the following process and makes things worse.

Create a file with NOTEPAD containing the following lines and save it as FIX.REG

-------------------------- Use text after this line --------------------------------
REGEDIT4
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

The best way is to use a PS/2 keyboard and mouse, but failing that, you just have to leave enough stuff behind to keep at least the mouse running. :)
