    I have an iMac running on OS X 10.5.8

    Just purchased 10.6 Snow Leopard to finally upgrade.

    Unfortunately, the disk drive is rejecting the Snow Leopard disk after trying to read it for 20 seconds

    Any solutions?

    Thanks

    Off the top of my head I can think of 3 things.
    1. You have a PowerPC processor. These are not able to run 10.6.
    2. The disc is no good.
    3. The disc drive is no good.

    If your iMac has an intel processor, try using an external drive.

    It has an Intel processor.

    I just ran a lens cleaning DVD through the drive.

    It still rejects its

    How likely is it to be the disk?

    I don't have an external drive

    Is your Snow Leopard DVD a new DVD purchased from Apple?
    Does the DVD surface appear clean, without scratches?

    Have you tried simply blowing in the CD slot, with a can-o-air, etc?
    You can also try a cleaning disk. (and you already tried that… )

    But, the DVD drives in iMacs are not known to have live long, trouble-free lives. Try a couple of other DVD disks, just to see if that's a general problem with any DVD - or could be a bad installer DVD (it happens).

    If other DVDs are also rejected, then you may need to replace that superdrive.
    Much easier (and cheaper) is to find an external USB DVD drive, and use that instead of the internal.

    Another option would be to burn a copy of your Snow Leopard DVD, on a USB flash drive. You would need to have access to another Mac, but you would end up with a more reliable, faster install from the flash drive, compared to the DVD.

    I purchased the DVD direct from the Apple Store. No scratches on the back of it

    I tried other DVDs , which were also rejected. Did use the dick cleaner to no avail. Looking for the can of air to blow it out.

    Will look into burning the copy onto a flash drive or using an external drive
