Then try a new stick. These things have limited life spans and your story is not unlike what I read when the stick fails.

i had a flash memory drive (Apacer Handy Steno AH220)of 256m capacity and my operating system is XP pro and it was working very well except since a few days i left the drive connected to my PC for few days and then i had a strang problem as i was trying to copy some files to it i had a message that there is no enough space to store and i checked the properities of the drive i found that it is half capaciy and when i tried to erase the data or format it i got a message that is write protected and when i tried to remove this write protection it fails and more strange i found that other folders on disktop are also write protected and i was unable to change this also , virus checking using norton was free, can any one tell me what is the problem and how it can be solved
