First of all you need to know that my computer has two physical hard drives set up in RAID 0. The day before the problem started, there was a short power blackout, during which the computer was working (playing a movie), and I didn't have a UPS for the computer.
After the blackout everything was OK, and I finished the movie with no problem.
The next day I started the computer and after 30 minutes or so it crashed.
Since then when the computer starts the RAID controller reports that, while the logical drive status is "OK", the physical drive status of the first physical drive (number 0) reports "An Error Occurred (0)", while the second drive reports "Successful(0)".
After that the computer tries to boot the operating system but freezes exactly after showing the Windows logo.
I booted with Hiren's Boot CD the linux distro Parted Magic 6.6 and ran all three tests, including the Extended one which lasted 3h 40m, on both disks and both were successful.
Again from Hiren's Boot CD I booted Mini Windows XP, from which the files in the (logical) hard disk could be seen with no problem.
I ran check disk on the drive without checking the two check-boxes "Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors" and it was once again successful.
After that I ran the same test with both check-boxes checked during the night and the next morning I found the computer frozen in the beginning of phase 5.
The computer is almost a year old.
I would appreciate any help
Thanks in advance...
