My new Class 4 PNY 16GB Micro SDHC card won't mount on my Sylvania SYNET7LP-DS 32GB Extended storage Froyo (2.20) Tablet. This is the second new card I returned, and still won't mount. When I press the Mount SD option, it says Memory Device Safe To Remove.
I should also note that the Format SD Card option is not showing up on the Tablet at all. I mean it's not there in grey or anything.
I also have the same tablet. I just installed a 32Gb micro sdhc and it worked right off the bat. It came pre-formatted, I installed it with power off, and on power up it was recognized and mounted.
