From the "Old School"..... K.I.S.S. !!!
Every MS OS including XP was designed to run on one hard drive with one partition. PC's have been coming out of the factory exactly like that for at least two decades.
When you install XP or any OS to a hard drive it will install itself totally into the '
C' partition and that's where it expects to find everything. As was said before (thank you Sir) when you start moving things around you will create a total Monster (I think total havoc was the term used).
Just let the installer put everything in
C and leave it there. The minimum size for
C would be dependent on how many programs and suites you intend to install.
Generally anything from 30gig to 50gig would be sufficient. Format the rest of the drive as a Storage partition and use folders to keep things separate, it's not necessary to create a new partition for each type of files.
I just leave everything pertinent to my OS in drive
C, so that when I do my backups of
C, I have everything it would take to do a full restore, if my main HD goes up in a big ball of fire and smoke. Don't laugh.....**it happens!
Then do follow these two simple rules:
1. Use a reliable Backup program like Acronis True Image and after you install it on your hard drive, use it to make an emergency restore CD.
From then on, you can even delete it off of the Hard Drive, to save space, and run it totally from the CD.
2. Make backups often, like once a week, and save the Backup Image Files to some media external to your PC, like an external hard drive or to DVD's that you can put in a safe place.
* The only bad backup is the one that you decided NOT to make.
I'm so into data backup and security, that I...
Force a new System Restore point on every boot-up, with a Script in my Startup folder.
Backup my data files to two external drives, daily, using a DOS batch file and the XCOPY command.
Backup my entire C drive at least once a week, using Ghost 11.5, run from either a CD or Flash Drive.
Going back 33 years, I've set up Backup schemes for Banks, Corp's and Home Computers.
It's just one of the things I do as a Professional IT Specialist.
Remember, "Keep It Simple".
Cheers Mates!
