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 allows to store up to 1992K on a 3 1/2 HD disk.
Mtools supports these formats only on Linux.
