I have installed the HD from my old machine (XP) to my new machine, also XP. I installed the old drive as a slave. The new machine sees the drive & I can see all of the individual files on Windows Explorer, but when I try to use a file on the old drive, eg a picture, or excel file or whatever, I 'm told that access is denied, or some similar message depending on the program trying to access the file.
DIsk Manager indicates the drive is healthy. I have confirmed the drivers are in place. It's a WDC-WD400BB-75CLB0, for what that's worth.
Any ideas are appreciated.
