Before the latest update my cd rom which had been working fine became unresponsive and would not load dvds. When I ran an the recent update the cd rom has started to load dvds sometimes and other times would not. It also loads them and then goes off-line and is not found again and then will come back after 10 minutes or so.
Any ideas how I can fix this please? Is the cd rom broken or is this a bug please?
It is most likely worn — i.e. the spindle motor has had its best days — or the lens may be dirty. Cleaning a dirty lens is difficult, and having it done by a professional is often more expensive than just buying a new drive.
Also, make sure you wipe the optical disks themselves from time to time.
