i ran chkdsk and it reported no problems with disk, so question is, are the first 8 dvd's now coasters or will, system image backup, start where it
left off. Thanks for any info.

Not sure this is of any use but here is the chkdsk result:

Well, it appears after doing serveral checks on the hard drive it did in fact have bad clusters, so it's my guess windows 7 backup cannot not copy those when doing a system image. I cloned the drive to a new one, and windows created a backup and system image without a hitch, and actually quicker than i thought it would. Which brings up another question. Doesnt clonning a drive also copy any bad sectors and should'nt windows 7 have treated it the same as original drive ?
