I have two identical disks attached to my Asus P5Q Motherboard which are not operating in RAID1 mode. Disk1 (640 GB, almost full) is/was 2 partitions (system, data - both NTFS) and disk2 (640 GB, 80 GB occupied) 1 partition (NTFS) for data only. The problem with the motherboard is, that the default settings are to operate the disks in RAID1 mode. Yesterday somehow the BIOS settings were reset to default (I suspect the battery is empty) and the disks were configured as RAID1. Unfortunately, I realised it only half an hour later (switched PC on and went away) and the controller had that time to mirror disk2 onto the other disk. I tried some recovery programs such as testdisk, photorec and pc inspector file recovery but could only find partitions/data from disk2. Any chance to still access the data from disk1?
