Did you know that the bigger drive mean the more space wasted.  And they are less efficient at 
handling small files.

Take a look at this..

Drive partition size	:	Cluster size
16MB	to 128MB			2K
128MB	to 256MB			4K
256MB	to 512MB			8K
512MB	to 1GB				16K
1GB	to 2GB				32K

Dos FAT support up to 2GB only.

This mean that a file of 2 bytes (yes two bytes) occupies 2K on a 100MB HD, and the same file 
occupies 32K on a 1.2GB.  Wow what a waste.  Imagine if you have 1,000 file with less than 15K, 
this will take twice the space needed on your HD.  Because a cluster can only be occupied by one 
file at the time.  So if you have a 67K file size, it will take 96K of real space on a 32K 
cluster size HD of 1.2GB.

If you want to know how many space wasted you've got on your drive.. try the following:

at the native dos prompt type:

chkdsk (to see how many file you've got on your HD and what's the size of your cluster)

Let say half of the file on your HD use half of the last cluster they are using.

ex.: I have 6,000 files: 6,000 / 2 = 3,000 X 32K = 96,000

WOWWWW 93MB lost in my HD for the fun of it..

Keep those partition drive to less than 512MB (8K cluster), unless you use HPFS or NTFS.
Or if you have only COUPLE BIG FILE on that drive and NEED THE SPACE FOR IT.
