Hi, I just finished running chkdsk with switches /f and /r on an external drive because Windows backup/restore couldn't use it to store a system image and recommended that I run it. It took a couple of hours and then the program exited with the message 'Insufficient diskspace to fix volume bitmap'. Firstly, I don't see how diskspace was insufficient as there are 79GB free out of the total 149GB, why did chkdsk say that? Secondly, should I worry about this or not? If yes - when I'm done worrying, what can I do about it? Thank you.
