Sony was expected to release its Nasne media hub back on July 19 in Japan. But one day before the release, Sony recalled all the units from retailers due to a defect with the device.It later turned out that the hard drives the Nasne used had been damaged in transit and there was no guarantee they would work. That’s surprising considering each Nasne would be secured inside packaging, with both the device and packaging being tested for handling the odd bump or drop. A teardown of one of the Nasne units that didn’t get returned has revealed the most likely reason why the hard drives malfunctioned so easily, though.Inside the Nasne there’s a single mainboard with the tuner and hard drive mounted directly on to it. The drive is actually a 7mm 2.5-inch Hitachi 5400rpm unit with a 500GB capacity. The cause of the damage to the drive looks to be the method used to attach it to the mainboard.Typically you see a drive either mounted in a bay and then attached to a board or screwed on to the board using some form of shock absorbent rubber washers. That’s not the case in the Nasne. Images of the teardown reveal the drive has been screwed directly on to the board just with screws.Using this method of attachment means any vibration traveling through the mainboard is also going to be felt fully by the drive. So if the Nasne is dropped or hit, the sensitive hard drive components will feel the full force of the impact.It’s no surprise then that the hard drives stopped working if a serious drop occurred during transit, and it looks to be an expensive mistake Sony could have avoided just by employing some shock absorption in the drive mounting.Read more at Tech-On!
