windows no disk error message ( Exception Processing Message c

I just solved this on my computer after plowing through a number of forums
and finding solutions that didn't work for me.

Running XP, Media center and readers for various camera cards.

The solution that worked for me was to disable all the camera card devices
on the computer.

Control Panel>Performance & Maintenance>system>Hardware tab>Device Manager>
disk drives

then one by one, double click on
generic usb CF reader usb device
generic usb SD reader usb device
generic usb MS reader usb device
generic usb SM reader usb device

and under "device usage" set it to "disable device"
