Specs: Windows XP

I am not technically minded so please go easy. I recently lost the use of my external drive through a USB port, and cannot use a memory stick. However, my wireless keyboard and mousse till work.

In simple speak, can someone please advise how i can get the ports back. Every time I try to access the external drive I am told that they have been disabled by the administrator. I am set up as an administrator, so am really confused.

The only way I can connect to the drives is to log in safe mode and log in as the other administrator (set up for emergencies such as these I assume)

Hi friend,

As I understand that you want to enable the USB Ports of your machine, you can make it by doing some changes in registry.

1.) Click "Start" button, and go to "Run"
2.) Type "regedit" and hit "Enter"
3.) Browse to following registry address:

"My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR"

4.) Find "Start" (REG_DWORD) in right Pane of the window and double click on it.
5.) Change the "Value data" to "3" then click "OK"
6.) Exit Registry Editor Window.

Thats all! Now you can successfully access USB Ports from your machine.

Hi Isha,

Many thanks for taking the time to respond. I have actually resolved the problem. My hard disk has 'died' I had a number of other issues after I posted this and have replaced the hard drive.

Thanks again,

Its good to hear. You are welcome :-)

And you can follow my previous response for similar issue.
And You can disable USB drive as well.
In My previous number, in 5th step, if you change the "value data" to "4", the USB is disabled.
Thats it.

Good Luck :-)
