I hope this is not to far from the subject. I also stole this from 
11ED Upgrading and Repairing PCs.

Last I heard none of the Standard DOS's or NT would recognize 
any FAT32 partition. Because they use a 12 or 16 bit number to 
identify clusters, they are also restricted to 2GB HD's. Using the 
Standard DOS Fdisk you can create only 2 partitions on a HD, one 
primary and one extended, however, you can divide the extended 
partition into as many as 25 logical partitions. You have to use some 
other program, such as Partition Magic or Gnu Linux Fdisk,  to get 
more partitions, or to have more than one primary partition. 

WIn 95 OSR2/WIN98/NT2000 use FAT32, and  NTFS (NTFileSystem) 
came along after win3.1. 

 Fat 32 uses 32 bit numbers to identify clusters, resulting in a maximum 
single volume size of 2TB or 2,048GB in size. 

NTFS, which supports file names up to 256 characters long (this includes 
all characters in the path, from the root to the file), theoretically can

support partitions up to 16 exabytes. It also provides extended
attributes 
and file system security features that do not exist in the FAT file
system. 

The FAT file system is currently the most popular and is accessible by 
nearly every OS, which makes it the most compatible, as well. FAT32 
and NTFS provide additional features but are not universally accessible 
by other OS's.  One reason may be because the FAT 12/16 systems 
place the file allocation tables (2 each) in specific locations and this 

information can be anywhere on a FAT32 system and NTFS uses another 
location not recognized by FAT 12/16 systems.
