For what it is worth, I did look for a thread covering this topic and did not see any. [Homer] Doh! [/Homer] I just spied this linknet post / thread, sorry. I have just completed a Repair Install of my XP Professional installation so that I could install the Intel Matrix Storage Manager driver and place two 750GB drives into a RAID1 array. The motherboard is Asus P5K Deluxe BIOS 0501 of 6/26/2007; the Intel Matrix Storage Manager is 18.104.22.1687. Prior to the Repair Install with XP Pro running the vanilla drivers under IDE SATA, my Acronis True Image 10 worked just fine. With the Repair complete and Windows back up to date, everything tucked in nicely and running smoothly, Acronis, when activated from the Programs menu throws Error E000101F4: Acronis True Image Home has not found any hard disk drives. I'm a sad Panda. How do I show Acronis some of my beautiful hard disk drive goodness? .
