I'm not sure what is the OS-dependence of the cluster size, but this
is how it depends on the partition (NOT the HD!) size under DOS/Win95:
Partition size Sector/cluster Cluster size
0 - 15MB 2 1K
16 - 127MB 4 2K
128 - 255MB 8 4K
256 - 511MB 16 8K
512 - 1023MB 32 16K
1024 - 2145MB 64 32K
(Taken from the Western Digital FAQ:
http://www.wdc.com/support/FAQ/general.html ).
In other words this means that if all 900MB left for DOS are
used as a single 900MB partition, then any 100 Byte *.bat, *.ini
etc. file will take 16K of the actual disk space - lovely, isn't it?
I don't know if something similar is true for the Linux partitions,
but I suspect so. Does anyone know the answer?
Cheers,
Kirill
