But back to my hard disk... I'm trying to use the following to prevent any more data loss:
carbonite.com
It's an online backup solution which integrates perfectly in Windows Explorer. They are offering 2 GB for free. You just have to richt click on any file or directory in explorer and it will schedule this file for upload. The file(s) are labeled with a yellow or green dot to indicate whether they're backed up or not. Their software will update in the background and slow down the very moment you start using your computer. If you leave it unattended it's going into overdrive (or so they claim)
Of course I have a backup USB hard disk now to prevent any more data loss.
For my convenience I also have installed Returnil and Reflect.
Reflect was a Giveawayoftheday. It allows backing up full system partitions
while the system is running and also supports full or incremental backups of files and directories using a fixed schedule (you need to utilize Windows AT.exe for that but it creates batch files for the backup)
Returnil is "locking" your system, so nothing whatever you do is saved to disk. What's it's good for? Say, you get this exe file from a friend and you're not sure whether it's a virus or not. Activate Returnil and just run it. After a reboot everything is "lost" and you still have your clean XP. Or perhaps you want to try this shareware you found recently. Or you got one of these famous "Keygen" tools from a russian site

Just activate Returnil and fire it up. After a reboot your system is clean again.
Soooooo! let's see if I ever have a data loss on this machine again! Bets are 1:1000 against.
