I have just reinstalled the system on my C drive with no problems. When I try to open the D drive, that has data on it, I get a dialog saying the drive is not formatted. How can I access the D drive without losing the data.
I had to get to Drive Management in a different way (probably UK version of XP Home) for your future reference
Start > Control Panel > Administrative Tools > Computer Management > (left side) Storage > Disk Management
I backed up data from the C drive to the D drive, seperate drives. I then reinstalled the system onto the C drive which was reformatted in the process, the D drive was not reformatted. I assume that it must have been damaged in some way , there were no accessibility problems before reinstallation on C.
