I recently bought a 500GB Toshiba 2.5 hard drive and put it in an enclosure. I tried to just plug it in and partition it computer 1 would not recognize it. When it tried to install the driver it says it can't because "Access is Denied". I tried using it on computer 2 and it worked just fine. I got it partitioned and set up to use. I even tried it on a computer 3 here at work and the computer here installed it just fine. I don't know why I can't use it on the computer 1 that I intended to use it on though. I also logged in as administrator on the computer 1 and I have the same issue.

It did work one time on computer 1. Right after I partitioned it on computer 2 and plugged it into the computer 1 it showed up under my computer and I could get into it. Right after I did that computer 1 started installing the driver again with an error and it disappeared.

It lists the hard drive as "unknown" under device manager and it also doesn't show up under disk management.

All computer involved run Vista.

I'm at a loss right now as far as what to do.

Any help would greatly be appreciated.

Try turning off the user account control while your logged in as administrator.

Go to Start-> Control Panel -> User Accounts -> Turn User Account Control on or off.

If it does or doesn’t work, enable user account control again afterwards.

First do you have access to install things on the computers at work?
