Super DVD CD Drive Does Not Mount After Wake Up

[davidtajgman]

Hi.

THE PROBLEM

I was watching a DVD when my G4 12" PowerMac battery emptied and the machine went to sleep.

After pluging the machine in it was difficult to awaken. I ended up holding the power switch down for more than 5 second to get the machine to respond. In the end, the machine booted and started up.

I did not expect to open into DVD Player, but I could not even see the DVD anywhere, including Hardware Profile in "About this Mac". Simply put, it is as if the Superdrive is just not there.

DIAGNOSIS PROCESS

DVD Player says that there is no DVD drive; Toast does not find see the drive; holding the mousepad down during start-up does not eject the DVD; zapping the PRAM and other RAM memory item does not result in the machine finding the drive (and ejecting the DVD -- but that is the smallest bit of the problem); using Firmware at startup to ask the machine to "eject the CD" gives a response that there is no CD drive.

My thinking is that it is software, not hardware -- something happened in that lost-energy-sleep-shutdown-wake-up process I did.

WHAT SHOULD I DO?

What approach should I take to solving the problem?

Is there some controlling bit somewhere -- a driver? -- that has become corrupted (Preferential Treatment found no problem)?

Is a reinstall of the OS the solution? If so, can it be done via a Firewire to the DVD drive on my Mac Mini (depressing T at start up on the Mini)? And if I resinstall, how with the Superdrive respond when the machine realizes that there is already a DVD in the drive?

Any ideas are welcomed. And many thanks in advance.

Hi David and welcome,

This may be a stab in the dark but could you please try putting the G4 to sleep by selecting Sleep from the menu, then close the lid. Wait a minute then open the lid and see if the drive is recognised again ....

Hi Spawn,

No, I am afraid that this has not helped. The event happened on Saturday evening, and I have needed to use the computer since then -- and it has been asleep, lid closed, awoken several times without incident.... and without the DVD drive being present, ha.
