mtools: bigger sectors
2.7.2 Bigger sectors
--------------------
By using bigger sectors it is possible to go beyond the capacity which
can be obtained by the standard 512-byte sectors. This is because of
the sector header. The sector header has the same size, regardless of
how many data bytes are in the sector. Thus, we save some space by
using _fewer_, but bigger sectors. For example, 1 sector of 4K only
takes up header space once, whereas 8 sectors of 512 bytes have also 8
headers, for the same amount of useful data.
This method permits storage of up to 1992K on a 3 1/2 HD disk.
Mtools supports these formats only on Linux.
