copying files with bad CRCs

[yawnmoth]

Say I wanted to copy a *.avi video file (xvid encoded) but was told I
couldn't because it had a bad CRC. Is there a way I could sorta just
copy it in spite of the bad CRC?

The reason I ask is because xvid (and MPEG1/2/4, in general) is a
rather resiliant format. A single corrupt byte may just mean that one
frame is bad. If every 20th frame is a keyframes (ie. i-frames, or
whatever), this means that only 20 - (frame position) % 20 frames are
bad. If there are 100,000+ frames, having less then 20 bad frames is
fairly insignificant. Yet it's significant enough for Windows to deny
you access to the whole file?

So, anyway, I think, in some cases, Windows' seeming refusal to let you
do anything with corrupt files is inappropriate. Is there any
work-around that I'm not aware of?

Thanks!

What's the source media type?

It's a hard disk.
