Hi phantom9056,
Re-seat the hard drive in case you are comfortable doing it. Here is the link for the service manual for your system: http://bit.ly/YIedD4
Check if the issue is fixed. In case the issue persists, I have added you as a friend. In case the issue still persists, please accept my friend request by clicking on my name highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button.
I am sending you a private message as well. Click on “Inbox” to respond to the message and provide system’s Service Tag on a private message so I may access your system records and check and check for further course of action. You could also click on Start Conversation to send a private message.
Please reply for any further questions.
