notice an I/O error? i hope you didn't give any jerks to the lappy while it was burning... since its giving errors in all software it most prolly not a software problem. try removing the drive and the controller to which it is attached in the device manager and let windows install the drivers again. see if this solves the problem. otherwise take it to the service center if still under warranty or open up the laptop if its not and try to reconnect the drive.
