Motherboard: 965P-DS4, windows xp x64. I have two Seagate SATA disks connected on ICH8R chipset (with AHCI enabled), these disks are C and D, and 2 Maxtor disks on Gigabyte SATA2 controller with hardware RAID 1 enabled and functional - disk E (2 disks - mirroring). I wanted to restore system partition C with previously created whole partition backup lying on D disk (tib file). Restoration was succesfull, but somehow TI managed to DEGRADE my hardware RAID1 on WHOLE other controller and disk it should not have bussines with. No harm is done, but rebuild took me ~4 hours of time! What could have gone wrong? Some kind of driver support lack? Should I unplug disks that are not involved in Acronis process? There is one thing I noticed while Acronis loaded in "dos" mode. Couple of "hde interupt failed" messages before it proceed with restoration. Please feedback.
