I thought my pandigital planet was broken when I couldn't get the sd card to mount. I called pandigital only to get a recording, and then I emailed someone at pandigital who told me to first format it. Then I said I had already formatted it, and it still didn't work. The Pandigital rep didn't know what to say next.
So, I go to the Geek Squad at Best Buy, and in five minutes after looking at the sd card I had in it, which was a 4 GB, he tells me it probably would need a 2 GB.
So, I buy a 2 GB sandisk micro chip, and turned the tablet on. Immediatly, my 2 GB card mounted and it worked. I'm so happy about this.
I cannot believe I called all these people who should have known what the problem was, and still couldn't help. I swear, it seemed like these Pandigital employees wanted me to just throw out the tablet [feigning it was broken], just so I'd buy a new and more expensive one.
Nowhere on these forums does it say that a 4 GB won't work in a Pandigital Planet and this is why the sd won't mount.
So everyone: If you have a 4 GB in an Android tablet,it's possible you too should change it to a 2 GB. Try it and see if it works.
2GB sandisks for tablets can be bought at any Best Buy. Get the 'PNY; Make It Simple' brand. It's about 12.00 and comes with the regular size micro also,so you can insert the tiny into it if you need to connect it to your pc.
I'm new at Android and these tablets,b ut not even the user guide directly explained that I would need a 2 GB sd card, and not a 4GB.
