I have 3 WD 3.5 drives and one Seagate that have all failed within 2 days of each other. They do not power up, they are dead in the water. My 1000 watt power supply is 12 years old. I am thinking that might be the culprit. Although I tested the sata cables and power cables on a new blu ray burner just fine. All drives are under warranty, but WD says electrical overcharge is not covered. Does this sound like an electrical overcharge to y'all? Thanks for any opinions.
