I have a 20" mid 2007 iMac I would like to upgrade to Snow Leopard. My problem is I would like to do a clean install but before I erase my hard drive I would like to make sure it in good shape. I found my AHT disc and found that the version number is 3A127 is for a 24" iMac. I don't know why I have the wrong disc. Is it usuable in the 20" iMac?
iMac, Mac OS X (10.4.11), Mid 2007 iMac
If you think that is the one for your Mac, try it.
If it doesn't work, you can call AppleCare and order a replacement DVD for your Mac. They will charge you shipping and handling.

Thank you Allan. I checked this article from Apple Support http://support.apple.com/kb/HT1883 and that is where I found the disc I should have is version 3A125, for my 20" iMac and the one I have, version 3A127 is listed for the 24" Macs. I'm not sure if trying the different size will possibly cause a problem for this old work horse. Any idea if it could mess it up? I thank you for your help.
You say you want to run Apple Hardware Test. If so that shouldn't hurt anything. It may give you steange errors but I doubt that it would do more then that.
If you are uncomfortable then call AppleCare for the correct DVDs.

Can I use a 24" AHT disc in my 20" iMac to check my hard disk?
