I want to undertake a project of reorganizing my PC, but am uncertain
as to how to exactly proceed.
I have:
ASUS P5WD2-E Premium
Pentium D-805 2.66 gHz
Windows XP pro SP2
Corsair XM52 1 G (2x512) DDR2 800
C: WD 2500KS 232g available/ 12.7g used
D: WD 2500KS 232G available/ 87.4g used
G: external usb HDD 186g available/ 104g used

I have all my data on the external drive and all the programs on the C
drive. the stuff on the D drive is where I attempted to copy the G
onto the D as a backup (so that 87.4g can be wiped)
But I abandoned that.
I want to RAID 0 the C&D drives, run everything off them and use the G
drive as a backup.
I do not want to loose all the settings and programs currently on the
C drive.

So getting all the stuff on Cinto a safe place, then reconfiguring C &
D for the RAID; then reloading the settings and programs onto the RAID
pair alsong with all the data currently on the G drive.

And establishing a good backup/archive system using the G drive
properly.
maybe I should seek local talent and pay him/her,
but I'd really like to try to do this myself as a learning experience.

The RAID setup seemed to scare the guy who did the initial install/
setup of my PC.

The stuff on the G drive is pretty safe, and I can reload all the
programs which are on the c-drive, only getting all the settings
working and so firth has been an ongoing process and my free time is
limited.
