I'm getting a persistent refusal to clone a 1.5TB drive to 2TB,  even though it passes several scans
On Reflect 6.3, 64bit in Windows 10   cloning fails about  75% though,  saying Read Failed 13,  Permission Denied- 32
I cant find help on these error codes, but suspect it has something to do with bad sectors
A program called HD Tune  found  damaged blocks at about this point on a scan & fix run-
 I assumed it had fixed or quarantined the blocks - but cloning still fails 
Windows Tools Check - reports all is OK on the drive 

Does anyone know if the above Reflex error codes give a clue as how this can be overcome?

Thanks

Have you run CHKDSK with the /R switch?  The default operation only looks for errors in the file system, not for problems with clusters on the disk as /R instructs it to do.  Note that this operation is likely to take a very long time on a drive that size, so you may want to plan that as an overnight operation if this is a system you need to use during the day.
