Somewhere in a drawer here, I have an original 1T Seagate Barracuda that
has 67,000 some hours on it, and has had 25 reallocated sectors since the
first time I looked at it when it had less than 2500 hours on it. Thats
the Joe Biden of hard drives, but unlike Joe, its never stumbled yet.
At 86, I am obviously in better shape than Joe. And thats not all that good...
Thank you Alexander.
Cheers, Gene Heskett
