I've got my laptop back from the repair shop. I am soooooooooooo happy. They said that ScanDisk couldn't repair an error on c:/ so they had to override it (Scan Disk is an MSDos programme) with ???? I don''t know. Then they could fix it. I brought it home and plugged it in, turned it on and what do I hear? Rattle rattle rattle. As though the a:/ was trying to engage and there was no disk in it. It was doing that before I took it to the repair shop. I wish I knew how to fix things myself.
