in an unrelated search, found this.
Related to my original search, has anyone seen any data about drive orientation vs longevity? im after proof that mounting a drive on an angle can have an adverse effect on lifespan
particularly interesting -

Isolator Impacts on Seek Settling
The major problem created when mounting a drive on isolators is the additional motion in the drive's baseplate at seek settle. This condition is commonly called the wind-up mode. The isolators are springs that allow the drive's baseplate to rotate when the torque created during a seek is applied. The isolators "wind up" during a seek and then unwind when the actuator is trying to settle on track. This unwinding creates too much motion for the servo system to fully track, causing an offtrack condition to occur. This either causes delays in settling or causes the heads to come off track just after settling occurred.
When writing data, the first event causes a slow seek, the latter event is referred to as a write retry. The slower seeks usually cause delays on the order of 1 to 5 msec. The write retry can cause a delay in writing data equal to the time it takes for the disc to complete one revolution. As a whole, this settling problem is larger for writing data than reading data because the heads need to be kept closer to the track centerline during the write process.
