MHDD - LBA Warning + single < 500ms block

Well, can't say RMA is my goal, but also can't avoid thinking about it when there are 51 "slow" sectors of an enterprise expensive drive vs. 0 of a WD Black (although this last one half storage capacity) - and the WD is older and more way more used.

But those are all great tips! Thanks for them all!
