FreeBSD File Server with ZFS

[mailinglist]

I've got an old P4 desktop computer running in the basement with a 1 TB external USB drive connected to that I use as a file server.  That PC is running XP.  It has recently become infected with some sort of virus.  I'd like to replace it with FreeBSD running ZFS + Samba (I need to access it from a OS X machine and a Windows 7 box).



1) Will FreeBSD be able to detect and use my TB hard drive as ZFS disk?  Right now it is only a single disk, but later on I'll and a second disk and setup a mirror.  Even as a single disk, the checksumming ability would be nice.



2)Assume I get everything setup in regards to step 1 and my OS disk dies.  How do I go about importing the ZFS external disk into another FreeBSD installation?



Thanks for all of the help!
