On this weekend, I have found one weird bug. If you have fat32-formatted drive (mine was usb stick), on Mac OS you cannot load files on it bigger, than 2.1Gb. Usual threshold for this file system is 4 Gb, but not less. But, if you stick this drive into windows laptop, you can easy load 3Gb files into, and, after first big file will land on drive, even being immediately deleted, on Mac OS allowed me to write big files (up to 4Gb, of course) to it. Is it FAT32 virginity?
UPD: Unfortunatelly, I cannot reproduce this behavior.
