My brother gave me a call the other day wondering what is options are since his computer was taking 2-3 hours to boot and having thousands of dialogue messages pop up. After discussing things we came to the conclusion that his harddrive was bad. He got a replacement from dell but still wanted to save his data since he was able to read it from the bad hd. He purchase usb hd. Downloaded knoppix and I walked him through the following process. We booted knoppix to make sure that we could see the old hd and the new USB hd, we could. So we proceeded to copy all of the information over.
