when I turned on guest account it corrupted NTUSER.DAT file

[Guest]

Hi. I wanted to set up a guest account to enhance security when others ask
to use my PC. I have Windows XP Home SP2 installed on a Pentium 3 PC. I
turned on the guest account and it somehow corrupted the NTUSER.DAT file
which I was able to restore using Windows Disk Checker. The file had
developed bad sectors which WDC fixed. While the file was corrupted it threw
away my user profile - I have the administrator account. Has anyone had this
problem and if son, how did you fix it? Thanks.

Files do not develop bad sectors - bad sectors (hard drive issue) may
develop corrupted files.

Has anyone had this problem

No. Bad sectors may render the *entire* system useless. Backup all
important data before that drive is going south entirely.

and if son, how did you fix it?

If bad sectors start to show up, any attempt to fix may or may not work.
Anyway, any success is just temporarily until the next bad sector appears.
