If you read the other thread you might know why your hard drive is running like that. Additionally 256MB of RAM is not that much when you are running WinXP. XP uses quite alot of it just for itself. And Xolox often needs to use alot of RAM and CPU time when performing certian tasks. Try runnung less programs and have less users logged in and wait until Xolox settles down. I have no idea how long that will take; it alldepends on the amount of stuff you are sharing.
