I have used compressed gas.  Traditional products use CFCs, and I have also
seen plain compressed air for this purpose.  The last time, I just used lung
power.

Has anybody tried a fire extinguisher? (the CO2 kind, not the water kind :-))
Presumably an air compressor would also work?  Bottled gas for cleaning my
computer is not the kind of thing I like spending money on.

I think either the kernel or the hardware writes CRCs for each disk block.
I know the standard backup routine just does a cpio -iBct (or whatever) if
you ask it to "verify the backup".  (You want the 't' option, or else you'll
be restoring.)
