Hello,

I'm going to presume a number of things. Let me know if any of these is not correct:
The drive is assigned a drive letter in Explorer (My Computer).
The drive is formatted.
The drive contains data (files).
If this is a hard drive that you inserted into a drive enclosure yourself, it is set as 'Master' with the jumper on the drive.

If it's "yes" to all of these, try the following in order:

1. Right-click on the drive and in the 'Open with' window, select, or navigate to 'explorer.exe' which is in the folder C:\Windows. Tick the box 'Always open...'.

2. Scan the attached USB drive for viruses (if you can).

3. Go to Start => Run and type in (or Copy/Paste) the following line:
regsvr32 /i shell32
{there is a space before and after /i}
Click OK

4. Right-click on your desktop and click on 'New' => 'Shortcut'.
In the 'location' box, type in (or Copy/Paste) the following:
%SystemRoot%\explorer.exe /n,/e,C:\
{there is a space after .exe}
Click 'Next' and give the shortcut the name 'Explorer'.
Click Finish
Use this shortcut to open Explorer.

5. Go to Start => Run and type in cmd and click OK
In the window that opens, type in cd\
You should see this - C:\>
Type in the USB drive's drive letter followed by a colon, e.g. E:
The USB drive letter should show.
Type in the following line:
attrib -r -h -s autorun.inf
{there is a space before each of the minus signs (3) and before autorun.inf
Next, type in this line:
del autorun.inf
{there is a space after del}

Detach and re-attach the drive.
