External HD got unplugged and now computer is being screwy

[quinncollard]

My mom accidentally unplugged my external hard drive while I was using it and my computer is messed up now. It's superslow to boot up and some programs won't open. A friend suggested I run the chkdsk command on the external, and when I do that it tells me it found bad clusters and I should run the command chkdsk /scan to fix them, but when I run that it tells me there aren't any problems.

Having an additional problem now. Trying to do the "safely remove hardware" thing to eject the hard drive to see if then I can open the programs that won't open, and it's telling me "The device is not removable and cannot be ejected or unplugged."

I don't have a solution for this and have no idea whats going on, however I would suggest backing up the files on it if possible before its too late..

Have you tried restarting PC with external drive removed, see if it is cause of slow boot - expect it is.

what make/model is the external hdd?
