As Methyl says, you've supplied no usable information on which to base a reply.
What exactly is a "big crash"
What do you mean by "recovered most of it". Did you use a reovery tool?
If the files are genuinely corrupt, then Chkdsk will remove them (or at least punt them all into a single identifiable location).
If, on the other hand, they are partially recovered files as a result of running some sort of recovery program, then (in technical terms) they are no longer corrupt - they may be entirely useless to you, but in terms of the actual files structures they will not be invalid, so it's pretty difficult for a piece of software to identify them.
