10.5.6: the superdrive makes a noise regularly

All the owners of portables know the characteristic noise that the Superdrive makes when the laptop is started or woken from sleep. Since the 10.5.6 update, certain people are confronted with a bug that causes in a regular way (approximately every 5 minutes) this noise as long as the machine is in operation.
As always with the bugs of Apple, we are unaware of the reasons that certain machines are touched and others are not. Someone, however, has found a radical solution to regulate this problem. She erased the software "diskutil" that one uses via the terminal for commands on the functions of the hard drives.
Once this file was erased, all returned to order. This seems to indicate that an unspecified process in the machines comes to regularly question the Superdrive on its state and causes this noise. We however do not advise you touching Diskutil unless you are particularly sure of what you are doing and have made a backup of your system.
