SD Card losing files

[Guest mr_chinchin25]

Hi,

I've just noticed that my SD card has just lost all the files it had on it. It was a 128mb Bytestore. Now when i look at the card using task manager, it says 38mb has been used up, but theres no files in there!!

I've tried looking at it through active sync as well, and the only folder is "my documents" with nothing in it. Theres no hidden files or anything! So what could be using up the 38 meg????

Is there any way of wiping a storage card clean?
