On counterfeit SD cards

[tkaiser]

However, what if you only purchase brand name cards directly from reputable sellers like Amazon and the like.

Then you can still get counterfeit cards: http://www.amazon.com/gp/customer-review...B00P3NMVVU

And so on...

And sure, avoiding sources where you get most likely only fake cards is smart. But you'll never know. So always check after purchase and get a refund immediately instead of wasting your time with unreliable hardware leading to all sort of errors that are attributed to software or 'the Pine64 itself' later since you almost forgot that the card could be the real source of problems.
