Yes, I was able to run a succsessfull backup with SSR using the ignore back sector option.
When a drive develops a bad sector, that sector is remapped to a spare sector. So once a sector is remapped it should no longer be seen as bad since read operations to the sector are deferred to the good spare sector. Does SSR honor this remapping sheme. In other words when SSR encounters a sector that has been remapped, does it read from the remapped good sector like the the OS would or does it treat that as an error condition?
That seems to be one possible explanation as to why SSR would fail while a Windows Backup disk image succeeds. Am I wrong?
