I have an 8gb Ultra Speed USB drive with these

I have an 8gb Ultra Speed USB drive with these problems:

1. I am not able to copy or delete any files/folders to it (or) from it. It alerts that the disk cannot be written to because it is write protected.

2. I'm not able to format it also. . It alerts that the disk cannot be written to because it is write protected.

3. Sometimes I’m allowed to cut/copy/delete/format it after trying so many times. So trying and waiting for the action.

4. I’m able to make a new folder and rename also. But not able to delete it. Very interesting that automatically a file (namely- USBC╚δ╬ä.; USBC╚3╔ä.; USBChñä.:USBC≡ßë.....etc...) is being created inside the folder immediately upon creation which is showing a huge size around 1.98GB to 3.36GB, but the actual size is not being occupied if I check its properties.

5. It is also slowly deleting my music files.


What can i do to resolve this.

Thanks
