Our experience with eagles was great, and we were eager to try the (larger) super-eagles. We soaked them for a month or so, then put them into production use. Whereupon, they started dropping like flies. It turns out the glue they used to attach the platters to the spindle slowly crept out over time, eventually coming to grief with a read/write head. This experience was wide-spread, and seriously damaged Fujitsu's reputation.
