Hi guys, I have this 4gb USB Flash Drive that I used on Windows... Since I bought a Macbook Pro I've been using it without problems, but yesterday I saw that the MBP kept saying that there were only fews MBs free, even if I deleted everything.. So I decided to format the drive with my MBP and all worked fine.. Then I tried it on my Windows Seven PC and it said I had to format it again in order to used it... So I did and now on Windows it says that I have only 200 mb available... Even if I try to format it again, both on Mac and Windows... No matter what mode I chose (Fat32, NTFS, PC Dos or sth like that and other modes on the MBP).. On my MBP works fine and all the 4gb... Can you help me please? Thanks, Paolo.
