My problem is twofold.. One: My PC won't recognise the hard disk when it's cold. At bootup it recognises everything on secondary IDE but nothing on primary. Is this a safety precaution or a symptom of malfunction? Two: My CD burner only occasionally burns. It works fine in most other ways, occasionally giving me a CRC error when copying EXEs. The burn LED only flashes when it is working and it never gives me coasters. My guess is it's software but this is just a guess. Suggestions to replace the drive will not solve the problem. Reinstalling drivers didn't help, checking device manager settings were correct didn't help. Enabling IMAPI service in windows didn't help. Help!
