Actually, the maximum size of any HFS partition is 2 GB ($7FFFFFFF) and it
does this by allocating several physical blocks (usually 512 bytes, but
can be larger on some devices (eg 1024 on a CD ROM)) to each logical
block. That means that on a 1GB formatted drive, the smallest block that
the operating system sees is 16 Kb in size. In other words, all of your
files will be multiples of 16 K in size, including the 200 byte text
files. Not very impressive, but I s'pose that if you've got a drive that
big, you can afford to waste space liberally...
