A bare eof operates on the last filehandle read from. perldoc -f eof.
The only place I'm going to get EOF from the OS here is IMG, and it
works as expected.

I thought about this, but everything I've read assumes that the files
begin on sector boudaries. The code I borrowed from only eaxmined the
first 4 bytes of each read, and the regex works anchored at the
beginning of the string. If I were only missing a few files, I'd say
this was it. But I'm not picking up any. All the EOFs can't be split
across boundaries, can they? Or can they? It's worth checking into
again. I was hoping to avoid reading the entire image into memory,
though.
Thanks,
