Hey there, emtasty123!
I'd follow @USAFRet's advice and determine the source of the noises. You might also want to reseat all the hardware components inside the rig and make sure everything is mounted properly. If the clicking noises are, indeed, coming from the HDD, you should backup your data from the drive immediately somewhere off-site and proceed with its troubleshooting.
Afterwards, use the HDD manufacturer's brand-specific diagnostic tool to determine the health and SMART status. Those clicking noises usually indicate an internal hardware failure on the drive, so I'd definitely consider replacing it. If it's still under warranty, you might be able to send an RMA request and get a replacement from the manufacturer's customer...
