Need help accessing files in an enclosure

My laptop's on/off switch broke this week and I took it in to be repaired. The technician removed the hard drive for me and put it in an enclosure. He told me he checked to see that I could bring up files.

He also told me it works like an external drive, which I have been using so I am familiar with them.

I cannot find any of my files on the drive. When I click on "Owner" under "Documents and Settings" I get an error message: Access denied. When I hold the mouse over it, I get an "empty folder" message.

I called the shop and the only suggestion I got was to search "Windows" for a file. I cannot bring up any files. When I do a broad search - such as *.doc or *.xls, I get only the files in the Program Files.

Can any one help me?
