Hard drive "ticking", no disk activity

[Cab]

I've got an Ultra 2 here that's only a few days old. In it is a Seagate Barracuda Green 2TB drive.

The drive is "ticking", every half second, even though the disk isn't doing anything. In fact, the ticking stops when I get disk activity. I just started noticing this recently, and am unsure if it was there all the time or if it just started today. I did a factory reset (running 4.2.21) just to be sure I didn't break anything, and still the same.

Any idea what is causing this?

Thanks

It sounds like a mechanical malfunction on your hard drive. It might be the reader head thats damaged or maybe the engine of the disk.

If you can, run a disk check of some sorts and see if it fails. I'd contact the place where you bought it and ask if you can get a replacement unit, as if the disk fails, you can lose data if you only have that one disk

You should run diagnostics on the drive download here > http://www.seagate.com/support/downloads/seatools/

Thanks for the replies! I'll definitely run a check on the disk.

Funny thing is, I let it run for a few hours and now the clicking is gone, at least for now.

Try the disc check. I'd just be on the safe side

Are you running your setup with one or two discs?

I had a Seagate external hard drive setup awhile back and when my drive started to go bad in the device, I heard a lot of clicks/ticks as it was sitting idle, and continued while I accessed the disks.
I agree with checking the diagnostics from Seagate.com (Seatools) listed above by HERBIEO.

Check the SMART+ information and see if you see anything out of the ordinary on the disks. Try to determine if it is disk 1 or disk 2. You may want to call into support to see about replacing the disks if you bought your ReadyNAS with drives in it.
