I have a Dell Dimension that is about 4 years old. I have two (1) 500 G external hard drives that are synchronized for backup. I purchased a multi-card reader for my pc tonight and when I plug it in while starting the pc, the external drives do not come up-they are absolutely "gone", not being read. The card reader come up fine. When I boot he system up without the card reader plugged in and then plug it in, I get a USB Device Not Recognized error.
Is there anything that can be done to get around this? The external drives are assigned so when I boot up and they are "missing" no other drives take their letters.
