windows xp - Unable to format, or access data contents of i-Ball pen drive

Every time I try to access the contents of my pen drive in any PC I see a dialog box with the following error message:

Disk is not formatted

I then give it the order to format the pen drive. However, it's not successful and gives me a dialog box with this error:

Windows was unable to complete the format

After I press OK it then give me this message:

Disk is not formatted.

Then I try to format via DOS prompt and use this command:

format i:/q/fs:fat32

But nothing happens to the disk.

How can I access the data from my pen drive?
