Hi all, I have an Inspiron 1545 with Windows 7 running, a Pentium Dual core 2.1 processor, integrated graphics and 4gb RAM. My issue is that when I have a dics inserted in my dvd drive which is not playing, the drive makes the noise a drive makes when you first insert a disc (ie reading it for a second approx) every minute or so. When there is no disc inserted, or the disc is being played, the drive does not make this noise. Does anyone know why the drive would makes this 'disc reading' sound every minute, and if there is a way to stop it? Thanks in advance.
