According to the *BM DOS technical reference, disk cluster addresses are
12 bits under MsDos 2.x and 16 bits under 3.x. Does this mean that if
I got 3.x for my 6300 with a 20 Mbyte hard disk and reformatted, I would
go from 8K clusters to .5K-2K (somewhere in that range, I calculated)
clusters? The reason I'm wondering is that I have 500+ files currently.
Some numbers:
8192 bytes/cluster implies 4096 bytes waste/file
4096 bytes/file * 500 files is about 2 Mbyte of
waste due to internal fragmentation.
Obviously, I'd like to reduce the waste that results from the 8K cluster
size. Does anyone know if my assumptions are true, and if so, whether or
not 3.1 (preferably; I hear 3.0 and 3.2 are bug-ridden) is available for
the 6300? If it is available, I'd need an address to which I could send
a purchase order - my organization doesn't believe in money :-).
Please email; if there exists enough interest, I'll summarize and post.
Thanx --- \scott
