I am the proud new owner of a small little Seagate 100G external HD. The problem: Its pre-formatted in Fat32. It mounted great in OSX. Transfered some files fine. In theory, it should be recognized by my Windows Xp machine too. Swapping them inbetween computers would be great. But the manual says its very dangerous for data quality. I was thinking of just formatting it using Extended Journaled mode like my Powerbook's internal HD is. Or making multiple partitions. What do you guys think?
