1M x 1k = 1GB = many 2K-char: A4 paper-sheets.
We NOberoners, would have several partitions in the 1st GB
Keeping a copy of the <partitions listing> can show where P8 starts & ends.
If you need important info in P34, and P9's partnTable is broken, you can't do
`dd if=/dev/sda9 ...` because the system needs to read along-the-chain of
extended/logical partitions' tables.
Previously I had 'fixed it'.
This time I <set the link/s of P8 to jump-over P9, to point to P10>.
Then P34 became P33 ......
It's the complexity of eg. little-endian/reverse-bytes/PartnTble-formats/
reading-previous-notes&logs...etc. which makes ETHO so powerful:-
to have multiple files viewable-together on-the-screen, and to be
able to color/extract related text.
Also the calculations, & hex <-> decimal <-> binary conversions make
for no easy solution.
Imagine ET.OpenAscii FileSize1GB ?!
