usb memry stick problem

[mrelectric]

i just used my sisters memory stick to load some files from one computer to another when i put the memory stick into the computer a window came up saying unable to read to you want to format? I said no! now i loaded files onto this stick that had other important files. it shows the stick as full and data as raw. Is there some kind of security feature to protect the data.when it is removed?

Normally it is better to use the Safely Remove Hardware feature when removing USB devices. Otherwise you'll run into problems like the one you've described.

ALWAYS STOP a flash drive before removing. Failure to do so can render your files useless.
