Yes, but not without losing all your data. If you have unallocated space (unformatted), you can create one or more partitions with them from within Disk Management without doing any damage to existing data.
Otherwise, your only alternative without reformatting is a 3rd party utility such as Partition Magic (7.0 or 8.0).
I just reformatted my hard drive yesterday and backed it up with Partitian Magic 8.0. I saved all my programs and games to drive E. where I have 80 gigs.. My problem was after I re-installed XP/ and SP1 patch and went to replace my programs in Drive C, all I had for programs was .dat files and NOT .exe files.. I was pissed to say the least.. I know I didn't do something right. I probably should of just dragged and dropped..
I don't think it works that way. The registry is a complicated thing, you must reinstall your programs so that they can properly set themselves up and make all the proper references (create keys etc.) in the registry. When you re-formatted/re-installed XP a new default registry was created. When you run an installation for a program you see all the changes that have to made during the set-up proccess. There are some programs that don't make any changes in the registry, but these are usually small, and exceptions to the rule.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
