Hi all, i'm new to the forum and to the Acronis ATI home 2009 software I purchased. I keep getting this error when I attempt to back up my system: "Failed to read data from the disk", followed by "Failed to read from the sector -2,112,859,743 of the hard disk 1". I am running Vista 32-bit and RAID 1+0 with four drives. I bought my copy since I was able to back up my sytem successfully within the trial period. Now i'm getting this error. Help! Thanks for the help.
