Let's take this out of the BTS as it is unrelated to the BR.

*.size is the disk size in sectors.
hda_{0,1,2,3}_sil.dat are all identical, but there are some differences
between .dat files for hda and hdb.
*.offset files are numbers close to the end of the disk, so apparently the
SATA RAID signature is saved 4 times near the end of the disk for
redundancy.
The offsets are probably some fixed distance from the end of the disk.
Question is if the disk size is encoded in the .dat files. IMO the main
reason to use the procedure you devised would be to generate disk images
of a different size (80GB was a bit of a pain for the conversion from
vbox to VirtualBox format for example).
