i tried to see the SMART status of my firewire drive, but when i issue the command, nothing comes back. there are three possibilities i can think of:
1) for some reason, this can't be accessed on a firewire drive.
2) SMART status is checked and stored on boot-up, and i've never had this drive turned on at boot time (due to all the crazy firewire drive problems that OS X has had recently)
3) my hard drive doesn't support it. unlikely, since it's a new western digital 200gb.
the command is:
diskutil info disk1 | grep SMART
(if your firewire drive isn't disk1, do "diskutil list" to find out which drive number it is)
thanks,
ben
