Stupid File Size Calculations

pudge on 2008-03-04T22:28:05

I back up my PS3 to a USB drive, which has a FAT32 partition. The archive folder reported only 3.2GB, but there was about 7.2GB in use.

The Finder and du both reported 3.2GB. I finally tracked it down to a file that is 4GB, but reports as 0. Most of the time. Note that even ls -s gets it wrong, but ls -l gets it right.

$ du archive2_00.dat 
0	archive2_00.dat
$ ls -s archive2_00.dat 
0 archive2_00.dat
$ ls -l archive2_00.dat 
-rwxrwxrwx  1 pudge  pudge  4294966784 Feb 21 22:21 archive2_00.dat


The Finder was similarly confused.

FAT32

Well, it is FAT32... What do you expect from a filesystem made during the Depression?

Actually, it is not so much FAT32 that I have a problem with here (I think?) ... it's that Mac OS X is misreporting what FAT32 tells it. Or something.
