|sounds like the drive is on its way out too, from the little info you describe, make a an image of the drive to an external hdd, then run the sony drive tests, you can also download test programs from the drive manufacturers website, |
better to be safe than sorry so make that image asap, you can use win 7 backup to create an image,
and if its still under warranty, call the service desk and ask them to replace the drive..
i hate computers!
but cant help myself....
