I've been quite unhappy with my test results with Western Digital MyBook drives (I have a series of them), and don't recommend them. They won't work as startup drives for Power PC Macs, and I've had a lot of problems with communication being lost during copies, across sleep/wake cycles, etc.

I've found the Seagate FreeAgents -- also widely available, and with eSATA, etc -- to perform better. Also, the Maxtor OneTouch series...
