I ran a hardware test using the "Applications Install DVD" after my iMac (Snow Leopard 10.6.8, Intel, last quater of 2011, 18 GB of RAM...) froze up on me for the first time in the middle of a job applicaiton...you know the drill...
Insert Applications Install DVD.
Hold down the "D" key...as computer is restarted...
I just wanted to make sure the hardware was working properly or was okay...
Since I had everything backed-up through Time Machine on my Time Capsule, I wanted to do a "fresh" reinstall of the OS and applications. I reformatted the HDD and then everything went smoothly until I inserted the Applications DVD. My computer will not read the disc! Thankfully I had my TM/C to restore everything; however, what happens if I loose both HDD's?
Also, I did not purchase the Apple Care or the iMac from Apple... Do you think an Apple Store, since in the media is in top shape (no scratches, bumps or bruises) and less than a year old, would replace the disc?
I even tried putting the disc in my Win 7 machine to see if I could make a copy or an ISO, but it will not even recognize it... And yes, I did try multiple DVD's and they worked just fine (or I would not been able to reinstall the OS to begin with).
Look forward to your feedback!
Just ask them.
Even if apple doesn't replace the disk for free there is only a small nominal charge for replacements. All you need is your machine's serial number.
Note, if the optical drive is damaging the dvd's you might want to get apple to look at that anyhow. Don't know what that would cost for the labor. Optical drives themselves are fairly cheap.
As for loosing your HDD's. Yes, it's good to have backups. But it's even better if you have two backups.
