"Ignore bad sectors"?

Thread solved

I wonder if I understand best practice for the "Ignore bad sectors" option.  (I'm mostly using the ATI2020 boot media.)

In general, I do not enable this option.  (As I understand it, if bad sectors develop, this way I'll be made aware with an error message that there are bad sectors.  [What about the target drive, is there some way to be made aware by ATI if bad sectors develop on it?])

OTOH, if I had a drive that I already knew had bad sectors and needed to be backed up, if I understand correctly that might be a good time to enable "Ignore bad sectors" option.

How did I do?  Did I flunk?

Coyote, ignoring bad sectors should only be used when trying to backup a disk that you know is already showing signs of failing and you want to capture as much data from it as possible but without being interrupted every time it finds a bad sector and having to respond manually!

The option only applies to the source drive for a backup as far as I understand - if a bad sector were encountered when writing to the target drive, then normal retries should be performed and the data reallocated to a good sector else a different failure error would be reported.

I have used this option several times over the past year when dealing with bad drives and the whole backup / recovery process took over 12 hours in each direction.  I was backing up a failing 300 - 500 GB drive each time, and using a 1TB spare HDD for the restore then running repair tools on the restored data etc.

Thank you very much, Steve!

I'm relieved that I haven't been doing it wrong.  (I can't forget that long long ago on Ghost I did do it wrong and paid a price for that.)
