When the Nvidia Shield first became available, it was iniitially only going to be offered with 16GB of internal storage. After a developer version with a 500GB internal hard drive began stirring up positive hype, Nvidia decided to release it to the general public as their “Pro” version. Perhaps they rushed the Pro model into production too quickly because now some Nvidia Shield Pro units are suffering from hard drive issues and are being recalled. Nvidia says only a small number of Shield Pro units are having issues and that the non-Pro 16GB models are uneffected.
If you were tired of waiting for Amazon to refresh the Fire TV and picked up an Nvidia Shield Pro, pay close attention when installing upgrade 1.4. If you see the fastboot menu while upgrading, then your Shield Pro is effected, even if it eventually updates successfully. Another sign of a faulty unit is severe pixelation of the top row on the home screen. If your Nvidia Shield Pro has experienced either of these symptoms, you should contact Nvidia for a replacement.
