Ok guys I have the 500gb flash drives…They show up as 500gb in all properties. I have am putting as many files as I can on them because I just can't believe it still...I even installed a program on it and ran the program from it....BUT.....A big but....When I put an avi movie on there it seems to get corrupted and I can not longer play it in Windows Media player. This file works on my computer fine...(all codecs are cool and all) ..When I press on the avi file on the 500gb drive it goes to open windows media player, which it should, then it says the file is unreadable or maybe corrupted...Everthing else is fine....I have stored all sorts of files on there....This movie thing is annoying me and I will not be happy until it works...Whats the point of having a 500gb flash drive if it can't store movies properly. It wont work with .wmv ....(because I make those computer video tutorials) It says "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file." How can a .wmv not be compatiable with Windows Media Player??????
