I checked out its NTFS code and I wouldn't trust it 100%. But the most cases it should work. This was one of the many reasons I wrote ntfsclone that is very similar to g4u in functionality (I think, I didn't have time to check it out) but it is optimised for NTFS, so it's much faster.

Yes, 'noerror' is what I also recommended to user in similar cases and they were very happy with the results :) [ ... excellent discussion how to backup drives with bad sectors ... ] > To my chagrin ntfsresize detected the existence of this now > needless Bad Cluster File and refused to make the last tweak. > In any case, I am temporarily using the drive as a 20GB drive > until one of: > - Someone has a solution to move forward. > - I buy Partition Magic > - I just create a d: partition (yecch). I've implemented bad sector support for ntfsresize in April and so far it worked fine and passes all my tests. Apparently you want to expand NTFS, right? That should definitely work for you also but shrink is much more trickier and I just didn't have time to check out all corner cases, that's why it's not released yet. If you're willing to test (you have already the backup), I will put it somewhere for testing in the weekend and if it works for you also then it's really time to send the patch to Anton.
