missing spaces in 1 gb sd card !!!!

[vincentnyc]

anyone here know a good free format sd card program for axim x30(mid)?

i have a 1 lexar (normal speed) gb sd card...i had it for about 6 month. and recently i notice i missing some space in my sd card. for example, i have about 300 MB of mp3 music files, 200 MB of video files, and about 100 MB of programs files or personal files on the sd card etc. etc. so that add up to 700 MB worth...the question what happen to the rest of my spaces...im missing about 300 MB of files. is my sd corrupt or do i need to reformat my sd card? if i need to reformat it....anyone here know a good program for it? thx in advance.

I'm not really sure about a free one, but flash format works fine...

how does a file get hidden anyway? i already use the regular file explorer and make sure to check the option to show all file..but i couldnt find any hidden file!!! i have about 300 MB space that is missing...i do transfer alot of video to my axim...can one of my video file be hidden when i delete them?
