What I meant was: why wasn't the drive preformatted to NTFS - which is what I was expecting?...I was surprised to find that the disk was FAT32, and the first thing XP did was reformat it to NTFS. Odd.
Not really. Disk areas are assigned by "cluster". The driver
a file cluster by cluster. On average the last cluster is only
half filled.
In FAT32 for various reasons, mostly addressibility, as the disk
size grows, the cluster size grows. So on large disks (bigger
than a few dozen gigabytes) the cluster size is enormous. Thus
there is a HUGE amount of wasted space.
