I've been using Acronis True Image for a long time. I attempted to back up the entire hard drive on a workstation and the backup stopped with a message "The file is corrupted" but it doesn't say if it's the source or the destination. And, it doesn't name a file as such.
Also, Windows 7 image backup doesn't work.
I have run a chkdsk /R on this drive but nothing changes in this backup scenario.
Oh yes, the computer is working fine. There are no apparent problems.
