Query: Chews through HDDs

Worked great for about 18 months, then began burning up my hard drives. I'm on my fourth new hard drive in the past 6 months. Fortunately, Western Digital and Seagate have 5 yr warranties.I've also had a hard time getting windows to recognize it after it goes into power save mode. My DNS-321 seems to work better at being recognized throughout my home network.
