Don't forget to pass 'noerror' and 'sync' parameters to dd when creating
an image, as otherwise you'll end up with truncated output, which isn't
a great lot of use :-)

(and possibly 'notrunc' when writing an image back to a disk, although
I've not had to test that yet)

Only downside of dd is that retry-on-error isn't documented. I have no
idea if dd even retries at all upon error (probably not), which would be
a handy feature to have when making images (as quite often I find that
errors disappear on subsequent reads). Keep on meaning to look into that
one and produce a patched version that'll do a configurable number of
retries upon error...
