I bought a 4gb mini SD from EBAY because I thought I got a bargain at $30 and was hoping I could have the luck some of you have had.

Unfortunately, when trying to put 4gb worth of data on there - the card has lost all of it's formatting several times. Right now, it still shows a 4gb capacity - but says 600 megs is already used up, when the card is empty. Right now I'm wishing I'd spent an extra $17 for the TopRam version instead of the Generic - but I think that'd be a gamble as well.

I'll keep trying to reformat this thing, but for now - I'm regretting my purchase.
