I searched and read the various threads in the TI forum and could not find a resolution that helps me. To summarize, my Acronis 11.0 boot CD doesn't find my hard drives (error E000101F4), but my Acronis 10.0 boot CD finds my hard drives. I have a brand new PC (Gateway FX530XV) with Windows Vista Business. I installed Acronis True Image Home 11.0 in it (I had to turn Windows Vista's DEP off temporarily. Can't believe this issue isn't fixed already...). There were no previous versions of Acronis installed in this PC in the past. My PC has two 500GB Western Digital SATA drives (model WD5000AAKS-2). The drives are in a RAID 0 configuration. They use the Intel RAID Controller built into the motherboard (82801GR/GH SATA RAID Controller). I use a USB mouse & keyboard. I created a boot CD with Acronis 11.0. When I boot up and try to do an image backup (a "My Computer" backup), I get the following error message: E000101F4: Acronis True Image Home has not found any hard disk drives. Based on suggestions in other threads in the Acronis forum, I created another boot CD with the following startup options: "acpi=off noapic" parameter". I get the same E000101F4 error. So, I tried a boot CD that I created on another PC with Acronis True Image Home 10.0 (build 4942, the latest available 10.0 build). I booted with this CD, and when I selected "My Computer" backup, it recognizes my RAID 0 drive and its two partitions. I haven't actually tried to do the backup yet, but it does recognize my drives okay. So, I have a some questions: 1. Any suggestions on how to make an Acronis 11.0 boot disk that will recognize my drives? 2. I want to install a new Raptor drive in my PC and make it my C: drive that will contain Windows Vista and Program Files. My existing RAID 0 configuration will be used for data instaead. I suppose I can try to clone my current drive to the Raptor (from withins Windows Vista), but I prefer to take an image backup of my current drive and do a restore to the Raptor (doing the restore from a boot CD). I figure it's good practice to ensure that I have a working disaster recovery solution. So, my second question is: if I were to boot using Acronis 10.0, I should be able to create an image backup and do an image restore just fine, since I'm not even using Windows Vista, right? 3. Acronis 10.0 supposedly supports Windows Vista. If I don't actually need some of the new features of Acronis 11.0, is there any reason to not use Acronis 10.0 with Windows Vista? Thanks, randman EDIT: I am using the latest version of True Image Home 11.0 - build 8053.
