scanpst fails...not enough hard drive space, but there is

[mstiles]

I've got what Outlook says are errors on a pst file. I scan the file using
any variety of scanners and fixers, they all say there's no error at all.

I run scanpst and it fails, saying there's not enough hard drive space to do
it, even though I know there is, and even though I've tried it without even
creating a backup.

thoughts?
