I have a Seagate external HD 2 TB desktop model. I have had it for some time . I use it for Carbonite back up. As of 05/07/15 The back up in carbonite and I get a message to re connect my HD. Now there in power light comes on the HD as it used to. I unplugged the power supply from the APC surge protector tower and plugged into another surge protection strip and plugged into the wall outlet. What could possibly happened here? is the power supply gone bad? or what please let me know if I need to buy another power supply or not? or is my External HD gone bad??
this is the power supply AC adapter I found on eBay, Seagate FreeAgent GoFlex Desk 9ZQ2P5-500 2 TB HDD HD Power Supply AC ADAPTER
