2 Hard drives

I have a new CQ desktop SR5113WM with Vista. I instaled my old XP hard drive
WD400BB, it shows up in the Device manager but it has no letter and dosen’t
show in Coumpter. I wanted to get old files from it. Would like help.

                                             Thanks!

go through this Sticky, if you have any more troubles, we’re here

You’ll need to assign it a letter.

To do this, go to Start–>Settings–>Control Panel–>Administrative Tools–>Computer Management–>Storage—>Disk Management.

Here you can right-click on the drive in question, and the menu that pops up should give you an option to assign a drive letter.

I found my problem, the XP hard drive had GO BACK instaled on it. So had to delet it first.

                Thanks for the help!
