Can't remember how to get my pc to read different hard drive with same stuff on it. I think to rename the drive just can't remember how. This was my 1st drive that I used and coppied it to another hard drive.
For windows 7 click on windows start button > right click on computer > click manage > click Disk management > on drive you want to change drive letter (right click) > click change drive letter and paths > click change button
For Windows 8, right click the start button when you are in the desktop mode then select Disk Management, then follow the same instruction that gjjolly gave from this point on
