Lost memory card space
 

Hi all, I have a 4gb Transcend MiniSDHC for my n810 that only registers as 2.8gb now, and I hope someone can help me.

Today, I hooked the tablet up to my PC with the USB cable, and began syncing my playlist over to the memory card using Windows Media Player. It got to about 97% complete, when media player crashed, and I got a message saying "Failed to write blah blah to J:". I unhooked the cable, and the tablet saw the card as corrupt, too. I opened File manager on OS2008, and it had an option to repair the card. I tried that, but it said I needed to reformat the card. So, using Filemanager, I formatted the card, but now it only says I have 2.8gb total capacity. So I'm just wondering what happened to the other 1.2gb, and can I get it back?

Thanks for the advice!
Mike
