    I bought this machine at an auction and it did work when I got home, but I have since tried putting a 500GB HD in it and I am having kernal problems.  I'm going to take it out, put it in an external HD case and plug into my other emac and just try to re-format the drive, then go from there.

    Hi Tim, I believe they were the same boards, just different CPUs & Graphic cards.

    There were a lot of 1.25G eMac taht had a terrible logic board defect. It was once covered with an extended repair program ut it expired over two years ago.

     

    A new logic bard can be very expensive/ If you live within driving distance of Eugene, Oregon there is a cost effective option there. Their replacement LBs are pricey:

    but they have a service that repairs the existing 1.25G LB instead of replacing it. Used to be around US$130.

    After doing some more investigation of this "new" emac, I put the old working HD back in and everything is working ok with that HD, but I am still unable to boot from a start up disk, I get a Kernal panic message.  The only thing I can think of is the disk drive is bad??  but I can put a CD in and it works fine, but could it be that it can't read a DVD, it does have a Combo drive.  Can that one part of the drive go bad where it just won't read a DVD??  I've got a Superdrive in my other emac, but I would hate to pull it if it still goes back to something on the board??  Any thoughts on this problem.

     

    On a side note I am going to try using Superduper to load the info from the old emac to the 500gb hd.  I tried going through the OS install process, but it wouldn't let me install on to the externalHD.  I did reformat the hd to mac extended, but not journaled, does that make a difference??

    Not unheard of, especailly if the drive uses separate lenses for CDs and DVDs.

     

    Before ripping things open to swap optical drives, get a drive cleaning disk. They are US$5-15 at most electronics and office stores that carry computer stuff.

     

    A lot of drives pronounced DOA by service providers are simply dirty and respond well to a cleaner disk.

     

    A friend has an older MacBook Pro and its SuperDrive failed and he was told by the local AASP that he needed to replace the drive--estimated at US$140-150 for parts and labor. I loaned the guy my cleaning disk and the drive is now working properly.
