PlayStation Knowledge Center
The PSN Status Indicator is now located in the top right corner of PlayStation.com
If your PS3 is scratching discs, please ensure that the system is on a completely flat surface. If you change the orientation of the system from horizontal to vertical (or vice versa) while the system is running, it may scratch your discs.
If you've followed the above steps and your PlayStation 3 is still scratching your discs, you will need to have your system serviced.
