My tab seems to be eating SD cards. I went to watch some movies and noticed the 4 movies I had on my SD were gone. I take it out to put them back on and Windows won't read the card, says it needs formatted. Upon that effort, it says cannot compete the format and won't even give me the option of FAT32, just NTFS and FAT. This is the 2nd time this has happened. The first was to a 16GB card, and this now to an 8GB. Both Lexar class 4 cards. I use the same 8GB card in my phone no problem ever. I find it very hard to believe that it's anything but my tab eating them/corrupting somehow. Anyone else having a problem with it eating cards? I'm probably going to send a mail to Acer Support and see what they have to say.
