Would that mean I have to blow away my precious ext4 partitions and
have them Win7rc NTFS formatted and run a full check-disk with
bad block checking enabled?

I can do that, but probably over the weekend since I'll have to backup files
and what not.

In the mean time, can I run a linux command (please tell me what it is or
I will search for something to run online) or tool while NCQ is disabled (via
libata.force=noncq) that can do a disk scan with bad block checking?

If that linux command/tool does not show errors, will that be sufficient to
demonstrate that my disk does not have bad blocks without the need to
run Win7rc?
