Recently I had a problem with my home built PC. My hard disk (C) (Samsung
250GB PATA) would not load into Windows XP. I have now swapped my secondary
disk (Maxtor 80GB) so that windows can now boot up into XP. However, when I
check in "My Computer" the second disk is present, but when I double click
the drive it states "The disk in drive E is not formatted. Do you want to
format it now?"

I know that the disk was formatted as I have been using it as my main "C"
drive with loads of stuff on it. As usual I hadn't taken a back up.

Can anyone help me please?

Thanks
