The tech who brought our 4th unit out explained that a lot of the techs let the DVR's rattle around in the door pockets or on the floor, which will ruin a hard drive. He told us that he always keeps his on the seats, and either he's right or we finally got lucky because the one he brought out works great. Heat is also a concern with these units. We used to keep ours in a cabinet with glass doors that we kept closed, but now we keep the doors open and make sure that the cooling fan on the botton has plenty of room to breathe.
Most techs will generally take care of the boxes they get, especially DVRs, not so much because they are delicate, but because they know we don't have many and they don't want to make alot of trips back and forth.
Generally when once the power's been off for at least 2 minutes, the head is parked, from this position only the nastiest treatment should harm the drive.
Pauses, skips and other video issues on recordings can also be caused by signal issues @ the time of recording or an issue with the tuner... Frequenty tuner issues go undetected as it will be on the good tuner when the box is run through the warehouse.
Heat is a definite killer - We used to nickname the Moxi boxes "Fireball 9000"s after an issue with the very first ones caused the heat sink to fall off the boxe's processing unit and one in a lab enviroment was said to actually catch fire. This issue did not make it to wide scale deployment (again, only the EARLIEST moxi boxes) and new rules were put in place about not running a DVR from a verticle position
To their credit Motorola actually uses some decent shock absorbing washers on their HD mounting, I was impressed when I disected a few dead 6208s
Still it could be better... and I've heard enough tales about contractors and MSO employees who should know better to know it's very possible for a box to get some pretty rough treatment.
