USB disks?

[Tom Horsley]

I'm thinking about getting one of the big USB 2.0 external
disks companies like LaCie, Maxtor, and/or Western Digital
sell (mostly for backup - perhaps whip out a script that
uses rsync to save copies of everything).

Do all these USB 2.0 disk drives "just work" under linux,
or are there the typical variations in compatibility that
seem to plague everything?

Any particular model USB 2.0 external drive with exceptional
linux support out there? Good experiences to report?

Thanks for any info.
