Synchronize USB hard drive between Mac and PC I have a large (750GB) FAT32 formatted USB hard drive and two computers - a MacBook and a PC - and I want to keep synched and duplicate versions of my work folders (images, word documents, videos etc) on each device: the hard drive, Mac and PC.

To achieve this I imagine a folder synchronization software running on both Mac and PC (ideally the same software) which would sync selected folders between the computer and hard drive.

Does anyone know of such a piece of software?

Many thanks!
Yeah, it's new and it's call BitTorrent Sync, just came out of Alpha. It uses a 32 character code you create to create folder based sharepoints...on any computer on your network, without futzing with Preferences. Bittorent does all the work, and you essentially can create your own cloud at will, with any internal or external hdd's.
