# The purposes of redump is to DiskDump each IMG file listed in every disk manifest to a temporary JSON file,
|
|
# then DiskDump that back into a temporary IMG file, then hexdump both the original IMG and temporary IMG files,
|
|
# diff the dumps, and save the differences in the current log file. Then we want to mount the temporary IMG file
|
|
# (which should normally be possible, since we used --forceBPB to create the temporary JSON) and dump all the files
|
|
# into an archived subfolder.
|
|
#
|
|
# After all that, we're ready to delete the temporary JSON and IMG files, as well as the hexdumps, and then redump
|
|
# the original JSON file and update the manifest with a list of all the files contained in the corresponding archived
|
|
# subfolder.
|
|
#
|
|
# redump.sh accepts two arguments:
|
|
#
|
|
# $1 is the directory to search for manifests containing disk images (eg, "."); this is a required argument
|
|
# $2 is an optional DiskDump argument (eg, "--forceBPB" if you're sure the boot sector(s) can be safely modified)
