HI,

My NAS started making a mechanical sound. What could it be? The casing or the drive?

Thanks

If the drive, the noise would be heavier in nature than a rattle in the case. A light rattle is probably case. Put your finger on the case to stop it.  If it does not stop, it could be the drive.

Do any drives have error lights?

Or of course Fans.  But if it is more of a click than a rattle then almost always it will be the disks.

If you have multiple drives in the NAS is it configured in a way that you can test it with one drive out at a time to see if you can stop the noise? If it is a drive it would be unlikely that multiple ones started making noise at the same time.

Fans are pretty easy to check. Just shutdown the device, use a knife/screw drive to block the fan(s), turn device on. If you can't reach the fans, check if still under warranty. If not, just open up the device and proceed as I said before. If the disks are easy to remove remove them. You will know soon enough if one or both are causing the noise. If you remove both at the same time (device off of course), and turn the device on, you won't have to be afraid of rebuilding arrays and stuff.
Generally, if it's a rhythmic ticking noise, it's the hard disk head stuck or seeking (pretty bad situation to be in).
