My main raid array just had a disk failure. I tried to hot remove the

IDENTIFY.
Can I assume my disk is dead?

To be honest, I've been expecting this, I just had no idea which drive was
going to fail. For the past 6-12 months I've been hearing this rather loud
clicking noise coming from that machine, but I could never pin it down, it
only happened a couple times a day (and it wasn't heads parking).
I'm tempted to try and reboot the machine, to see if the disk comes back.
But I'm worried the array might not come back (for whatever reason).

Looks like it but show smart stats as well-- they may show what/why is
failing, if not try to run a smart test (short) and see what the error is,
or if it passes successfully.
smartctl -a /dev/disk
or smartctl -d (cciss,3ware),drive -a /dev/device
