Beg to differ, Jim. The "New Detectives" show I was referring to involved
a military case that I was peripherally involved in.
IIRC, the agency was Air Force OSI. They were given the hunks of a 5.25"
diskette that had been cut into pieces by a serial murder suspect. The
local cops just swept (most) of the pieces into an envelope and sent them
to the OSI folks. The reconstruction was a lot of fun--and something
suitable for the CSI TV show. The trick was to assmble the pieces as best
as one could, replacing missing pieces with bits of new diskette media and
using a low tack adhesive to glue the bits down to another cookie.
Several drives got creamed in the process of reading it, but about 70% of
the data was retrieved--enough to movtivate a plea bargain. The mangled
floppy, obviously, had the guy's personal journal on it.
Anadisk was used to read the reconstruction and then another program was
written to sort the data out.
Out of all of the kiddie porn and white collar prosecutions that resulted
from using our tools, that's the one I'm really proud of.
So, could one do the same with a CD-R? But then, 10 seconds in a microwave
oven is enough to destroy that medium beyond recovery.
