ext3 on Os X
there is a way to mount ext3 OS X (Leopard only? ) http://fuz2y.com/?p=1 according to that post. We have a USB drive we use to backup our work server.
We have a NAS at work - it failed to format the attached USB drive as FAT so we did it as ext3, then thought we could easily format this in another OS as FAT, as the NAS software seems a bit scant sometimes.
We are now having to download a mini linux live CD to try this way, if I cannot get the mac way above to work. Gah!
