I'm getting the dreaded disk read error message on my now 3 year old pc. The problem there seems to be no way to restore, repair or just delete everything and start over. Every time I run my windows boot disk it tells me the drive is locked and none of the available options are possible. I'm using windows 8.1 and a generic Samsung 1TB hard drive. Does anyone have any idea what I can do. I dont really have the facilities to link it to another computer and I have taken out and reconnected things in different port, even moving my graphics card. The Bios recognizes the hard drive, but it does nothing else apart from sit there.
