Review on Seagate STEB6000403 Expansion Desktop 6TB External Hard Drive - USB 3.0 for PC & Laptop by David Burrell

Wow what a disappointment. This was purchased in August as an external backup device for my computer. My computer is powered by a Tripp-Lite backup battery, and power also flows through one of my high-end surge protectors. There have been no surges or storms since I bought it. I've been in the computer industry since the 1980s, so I'm very knowledgeable about how systems work and what can cause damage. No temperature fluctuations, the drive has never been bumped or moved. Nothing. Today I noticed a warning in my backup program. Seagate hard drive is not visible in Disk Management. I tried the unit on the 2nd computer in the house and it is dead dead dead dead. UPDATE: I went to the Seagate website and entered the drive and serial number. As mentioned, it was purchased here at Revain in August 2016. Date of manufacture on disc 02/27/2016. Seagate says "warranty expired". It turns on normally and the blue LED is on. There's no scary clicks or rattles, and you might feel the drive spinning, but not all computers see it. I can't even try fdisking because my operating systems don't register the hardware. Seagate used to be better. Thank god I make redundant backups.
