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