Even if it does your drive may be failing, take appropriate action. I would then run a chkdsk, to fix errors and then hope that it works. If you didn't run CHKDSK /R first, then the OS partition's problems would remain as they were and any attempt at a normal backup or cloning would, of course, still show consequential errors.Īs for having been able "to use the manufacturer's restore partition and put the C: drive back to original state" I'm really not sure where that entered into the picture or with what result in relation to the original objective. The most common cause of a failure to back up is a failing hard drive. Then got to 99, and Reflect reported: 'The handle is invalid'. About 50 in to the restore, got a Windows message: 'The last USB device you connected to the computer has malfunctioned and Windows does not recognize it.' But the restore continued.

If that was successful, you might then have been able to image the entire source drive normally as it was its OS partition that had been causing the problem according to what you said earlier. As suggested, ran chkdsk and then connected via USB3. Did you then run CHKDSK /R on source drive's OS partition first (whatever "drive letter" it had there) before trying any of those other things? That's what I was suggesting above. When you had the drives installed in the Win7 desktop, the source drive's OS partition would have been assigned a different "drive letter" other than "C:". Sorry, but I'm afraid that sequence lost me completely.
