I recently upgraded my home PC's (2 of) to the test version of Windows 7. I took my usual USB backup of both using a DVD on my main machine and a USB stick (PLAY.COM 4GB) without any problems.
HOWEVER, I discovered that one piece of hardware on the second PC would not work with Windows 7 and there were no updates to allow it to do so, therefore I reverted back to the original XP installation.
When I went to restore the backup from the USB key, it recongnised the key, but when I try to explore its contents, I get "Please Insert disk in drive e:" and it refuses to open. I tried the key on my main Windows 7 machine and it says "this disk needs to be formatted"
This is desperation, as the key contains four years worth of documents and photographs...
Can anyone help?
