I said it doesn't appear on 'my computer'

Okay, disconnect everything considered removable device J, restart your computer, uninstall all drivers pertaining to said device(s), and do what it prompts you to do, such as restart etc... I recommend restarting before and after uninstall, now, install through the driver disk and make sure you follow the onscreen instructions thoroughly. If this doesn't work, the only other thing is virus or some other type of infectious malicious software.

Another thing to check is did you install any drivers or software/hardware prior to this error? If so, remove or reinstall said drivers/software/hardware. If this cannot be done, you may have a problem with compatibility even though I say it seems very unlikely it's still possible.

Cheers.
