Are you able to see the drive with an assigned drive letter in windows explorer?
If not, do a start search for "computer management" and click on disk management. Find your drive in the list and assign a drive letter.
If you're seeing the drive letter in windows explorer but get an "access denied" message or similar, you may have permission issues.
In this case, right click the drive in explorer->Security->advanced->change permissions.
Now select your user name, click edit and hit full control. tick the check box at the bottom and hit ok. again tick the check box at the bottom and hit ok.
Now go to the auditing tab and do the same. select your user name, edit and select full control, making sure to tick the box at the bottom that applies to sub contents.
Go to owner tab, edit, select your user name, tick replace sub containers and objects at the bottom and hit ok.
Hit ok till your back to explorer and hopefully you should have access to your files.
Hope this helps.
