3.5. Does FreeBSD support JAZ, EZ and other removable drives?

Apart from the IDE version of the EZ drive, these are all SCSI devices, so the should all look like SCSI disks to FreeBSD, and the IDE EZ should look like an IDE drive.

I'm not sure how well FreeBSD supports changing the media out while running. You will of course need to dismount the drive before swapping media, and make sure that any external units are powered on when you boot the system so FreeBSD can see them.

See this note on 'formatting'.
