When I create an image in Acronis 8 a dialog box opens and reads" E000101F4: Failed to read data from the disk. Failed to read from sector 1,295,605 of the hard disk1." I clicked on IGNORE and continued. Then a similar dialog box opens and reads a similar "Fail to read sector." It is another sector. NOW I clicked on IGNORE and continued. Nothing seems to continue. What can I do to complete creating an image to my external Maxtor USB hard drive?
