ok. Thansk! Sorry. It's just that I'm afraid I'll lose my datas right now. Thanks.
If you fear that, ensure that you back-up your data so no matter what happens you don't lose that data. You need a back-up/recovery strategy so you can recover from a system failure of any kind.
I take a weekly image of my Primary hard disk partitions and store them on a second hard disk, it could also be saved to DVD and stored away from your computer or saved to an external hard disk enclosure.
I take daily back-ups of my data that constantly changes, .doc files, email, address book, favourites, etc. anything you don't want to lose a weeks worth of updates covered by the disk imaging software. So at worst I could lose 1 days worth of changes, so the lose wouldn't be total.
