Not neccesarily. If your disk is clicking that generally indicates that you have a problem with the read/write heads attempting to scan the surface of the platter. If you hear a clicking, grinding or other odd noice from your disk we suggest you shut it down immediately and send it in. If it is in fact a head crash, you may need advanced recovery.
It could also just be a problem with the electronics, motor, actuator arm or any number of problems. You best bet is to pack it carefully and send to us so we can give you the best chance of recovery. Don’t give up hope – if we recover your data you pay a reasonable flat fee!
