Cloning an important drive that has some bad sectors
Posted on 2014-03-21
One of our old workstations has some software that is not replaceable. I have a new drive and I am using HDClone to clone it. We're talking about 30GB of data. The OS is Win XP Pro SP3. This morning I connected both old and new drives to another machine using USB ports and booted up with HDClone's bootable CD. HDClone found all drives OK. It went ahead and did the clone which took 3 hours. It found 13 bad sectors, presumably in the original drive. The OS and the software of concern have been working OK, so I suppose the bad sectors are either at data that's not being used or where there never has been data. After the clone run finished, I found that Windows Explorer recognized the clone with a drive letter, but it would not allow access and says that there is corruption. The original IS accessible by Windows Explorer. I went ahead and Formatted the new drive, and as expected, now it is accessible, but of course with no data. At this point I ran CHKDSK as Read-Only on the original and it found 8K in bad sectors. What should be my next move?...
1. Run CHKDSK /f on the original, check it, especially the valuable software, for validity, then run the clone process again and hope for the best?
2. Run the clone process again, assuming that the clone will again be inaccessible but maybe CHKDSK /f can fix the clone. (I should have at least tried that before the format.)
3. HDClone has an option to copy data sectors only rather than a simple sector for sector. Maybe I should try that. Would that copy the Registry data OK, so that the software app would work?
I understand that there is significant risk in running CHKDSK /f as this is more concerned about only healthy sectors being addressible than it is about preserving existing data. Is that true?
What should be my next move?
