I am trying to help someone who was using an older build of Acronis Home True Image to back up to a 160GB external USB drive. For the holidays he bought a SATA2 500GB WD hard drive and a Antec external eSATA/USB case. When he attempts to perform a complete backup of his computer he gets the following error: "E000101F4 Failed to read data from the disk. Failed to read from sector 208,823 of the hard disk 1" We have tried saving the back up to the root of the newly formated 500GB NTS partition as well as doing a sector by sector back. The results are always the same. The above error occurs. A chkdsk of all the hard drive partitions being backed up shows no problems. There are two internal ATA drives, one 160GB and the other 80gb plus the external 500GB hard drive via USB.
