On my flash drive my files has turned to symbols and numbers can not read

It sounds like your files are encrypted (for some strange reason). You will need to figure out how to un-encrypt or disable encryption on the troublesome drive. It might help further if you stated what OS's are on the computers involved.

Sounds like there are sectors of the drive are failing. Chkdsk can help mark those as not usable. If drive is old and problems persist then consider getting a new one.

I found it, from another web site. SmartUSB.net.

It explains step by step, how to change font color in a flash drive.

I think for some reason there is a limit to the number of files (nb: number of files not amount of space used) that the root directory can handle. Try making folders and moving files into these to cut down on the number of root directory entries.

The flashing folder with hard drive symbol is telling you that the computer cannot find a bootable system folder (operating system). This could be because the hard drive is working properly, or the operating system folder has become corrupted. Try booting up from the system CD or DVD that came with your Mac Book Pro and see if it can repair your hard drive.
