Seagate appears to be having an issue. A fairly large number of drive models, recent models, both enterprise and desktop, appear to have some serious failure issues.
We have been using Seagates for a while, they have been reliable. We have seen a higher failure rate than they report, but we chalked that up to a assuming Seagate marketing using a somewhat optimistic interpretation of test result statistics. Call it a mis-set calibration point.
I think we are going to test several of the drives we are getting back next week for this failure. I hope Seagate gets its act together. I like their products. Customers have long memories on bad drives, and once that meme gathers steam, they could have more (self inflicted) problems.
