Apple's extension of the iMac 1TB Seagate hard drive replacement program was mentioned last Sunday, and late this week customers began receiving email reminders to schedule a drive replacement. If you're an iMac owner but not certain your machine is covered, you can easily check your serial number via the online validation tool.
While the Apple service program covers replacing your potentially problematic drive, it does not include backup or restoration of your OS, applications or data: that is on you. Please take our advice and spare yourself much pain
