I have a touch pro for sprint, and a class 6 8GB microSD card. I had a lot of movies on it, along with a whole mess of music, and about a years worth of CAB files, photos, etc. Anyways, when I checked my memory card on my phone, it displayed that it only had 1.5 GB left. I plugged it into the computer, and it displayed the same. So I proceeded to check the file sizes inside the card, and none of them even matched up to 5GB overall. So I backed up a majority of the files to my laptop, then formatted the card, and pasted the files back on the card, and shazam! lol...(just really wanted to say shazam...) There is only 2.5 GB used on my card overall now. So apparently when I would delete files from my card, it would still have an image file from the memory on it. Just figured I would post this and see what others said.

I noticed the same on my old 1gb microSD of course i havent lost so much space, only 100MB.
