subject: Cluster algorithm

Quoting (part of) a msg from you of 27 Jan 1996:

MR>Is there anything wrong with this *other* than it not taking into
MR>account th 12-bit FAT of a <16MB drive?

 GW> Yes. The minimum cluster size on 16-bit FAT is 4 sectors (2048
 GW> bytes) (another Microsoft odditity :-( ).

George, 
Sorry, this is not quite correct. DOS or OS/2 allows smaller cluster-sizes,
but 'Format' does not give you an option. Long time ago I wrote a program
to bypass this limitation. With this program I can modify any volume (on
harddisk or diskette) and choose for 1, 2, 3 or any other number of
sectors/cluster (of course it does not allow you to exceed the 65500+
number of clusters). And DOS or OS/2 do not complain about this 'odd'
partition size (apart from CHKDSK, maybe). 
So for example a 60 MB partition can have a 1 KB clustersize. 

Cheers, Rob
