Superdrive replacement in flat panel iMac

Question

I have seen this addressed in bits and pieces on many different forums, so I figured it was about time to try and get this information in a place where it could be easily found.
The problems encountered by many iMac G4 flat panel users with their superdrives seem to have only one common solution.......replacement of the drive.
There are numerous fixes that at best are temporary solutions to a problem that will only get worse until the drive fails completely.
This model iMac seems to be extremely susceptable to the accumulation of dust, which in turn causes the internal parts to overheat, which probably leads to premature failure of the laser components of the drive.
In 10.4, the common error is related to laser power calibration failure, in which the laser is unable to either read or write to the disk in order to determine the correct write speed for that disk.
Earlier versions list similar problems, but the wording is different.
Using a different type of media can be a temporary solution, if the problem is just beginning, but at best, probably a few burns is all you will get.
Using a lens cleaner will help in some cases, but also temporarily if internal dust is the culprit.
Other solutions, including burning to a disk image, then using disk utility to burn the dvd will also work, occasionally, as will creating a new user account.
The ultimate solution is replacement of the optical drive, and a good internal cleaning of the iMac.
Cleaning alone may solve the problem, however, since you already have the unit disassembled, and the optical drive removed for proper cleaning, it is best to go ahead and replace the drive, since the newer, dual layer, 16x drives are relatively inexpensive, some for under $40.00 US. Also a good time to install that new HD since it is removed along with the optical assembly, and even a little extra ram.
You should be aware that doing this yourself will no doubt conflict with Applecare, if you have it, but on older models without the warranty, most people should be able to do this themselves.
This URL .......http://www.xlr8yourmac.com/systems/iMacg4/imacg4takeapart.html...........provides a take apart guide and step by step directions to replacing the components, and is very easy to follow. Make sure that if you don't have a second computer, that you print these pages prior to beginning disassembly of your iMac.
It is really not as complicated as it looks, and if you have any mechanical ability, and a little patience, it can be easily done within an hour.
Also be aware that if you install a dual layer drive, You will not be able to access the dual layer feature in iDvd unless you install a patch from this website........http://www.hardmac.com/niouzcontenu.php?date=2005-05-26#4090.............the file name is MBiDVD4ALLDUAL.sit.
This will allow you to use those dual layer disks with iDvd.
There are numerous drives that will work in your flat panel iMac, personally, I installed the Pioneer 110D, and so far, it has worked perfectly, including burning the dual layer disks.
The 110 is actually slightly smaller than the original drive, and was easier to install, than the other model was to remove. Most drives are standardized in size, and all mounting screws positioned in the same place, so as long as the drive you choose is not larger than your original, it should work.
I hope this helps a few of you out, I know about the time I spent searching for answers before finally giving up and just buying the new drive.
You sure won't regret being able to burn at 16x, or getting those ninety minute movies on one disk.
Good Luck
