I Ran the kav_rescue_10 disk with default settings, nothing was found. I then ran a full disk scan of C: drive. After 8 hours, nothing was found, but when I rebooted, the disk data was mostly gone. Windows XP, SP3 with a RAID 1 using intel matrix storage. First it said no NTLDR, so I recovered that using repair mode from the windows install CD, but then I discovered most of the data on the drive was missing. All the data is basically lost. Fortunately this was not my main system and I had a backup copy on a third disk. The rescue disk scan feature will corrupt a Windows RAID 1 setup (ich10r chipset).
