Did you ever figure out this error message you're getting from windows? ...There is no disk in the drive. Please insert a disk in the drive \device\harddisk2\dr8.
I recently installed a media card reader into my PC and now I get that message at start up and I cant do any thing until I push either one of the three buttons " continue or cancel or retry" I have somehow traced it to a windows system32 process called CSRSS.EXE and it is a needed part according to some research I did on it but in some instances I read it is a worm or virus that attaches itself to your e-mail and get you password info and allows someone to access your computer.
I still can not get rid of it. Anyone with information on this or a similar problem please post here and let me know if there is a fix available anywhere. I have not tried to un-install the hardware I put in right before it started and I will try to do that but i sure would like to hear more about this from others.
