It normally always is. Yours has a VALUE and WORST of 9, which is way too low, a failure on any other drive. To the best of my knowledge, it indicates mechanical problems when seeking. The very high ATA error count seems to be from rather generic 'Device Faults', I would guess from seek failures. Consider it failed. RMA it or trash it.

SMART support: Enabled SMART overall-health: PassedNothing obviously wrong there. unRAID will 'red-ball' a disk if a write to it fails for any reason. This can often be an external factor such as a glitch at the cabling or power level rather than a real problem with the disk itself. It is therefore a good idea at this point to check that all cables are securely plugged in. Once unRAID disables a disk it will stop writing to it and will start emulating it using the combination of the other disks plus the parity drive. At this point your data is all intact, but you are no longer protected against another disk failing. unRAID will not clear the disabled state until the disk has been rebuilt. If you have a spare drive then you can stop the array assign the spare disk start the array to rebuild onto the replacement disk This is the safest way forward as you still have the 'failed' disk unchanged for recovery purposes on the off-chance the rebuild fails. Alternatively since the disk looks as if it is OK, then you can probably safely rebuild the disk back onto itself. To do this the sequence is stop the array change the disk to unassigned start the array with the disk unassigned. This causes unRAID to 'forget' the previous assignment stop the array assign the disk back (unRAID will now be offering to rebuild it) start the array to run the disk rebuild. When this completes the disk will be returned to the 'green state.

The only item I see that you may want to deal with is the Load Cycle Count, somewhat excessive. You may want to run some form of wdidle on the drive, which I understand may extend its life. I have no experience with this however, so you will need the advice of others.
July 22, 201510 yr Thanks for the advice, guys! It appears to be an issue with my sata extender card (a pci-e card with two sata ports and 2 usb-3 ports). so now it's indeed rebuilding.
