My stuff when i go to my stuff folder, it says that memory card has an unrecognized format. Reformatting will erase all data, Reformat now? when you hit yes it says error. If you hit no it goes to the regular my stuff page. it pops up every single time. how do i get rid of it.

I have the same problem with my a707, but usually only after the phone has been turned off or lost power. All I do is pop the card out, then push it back in. The phone then recognizes the card and takes its sweet time reading it (2GB) before letting me go on to "My Stuff"!

Do you have a card reader in your pc that you can put the card in?  And of course the adapter to convert microsd to sd card size?  If so then just put the card in pc, right click on the icon when it appears in your "My Computer" folder, left click "format" and format the card there.  It's possible that the data on the card got corrupted somehow and maybe why the phone is having trouble reading or reformatting it.  If the card still doesn't seem to work after putting songs or pictures on it, try using the card in a compatible mp3 player or a friend's phone with a microsd card to see if the card works, if it does then the problem is probably with your phone.  I have heard about compatibility problems with some phones and certain brands of microsd cards, not sure if this is one of them.  Hope this helps.

If you want to just get rid of it just take out your memory card and dont use it. otherwise you have to reinsert you card for it to work
