Traditionally hard drives have come with a data sector size of 512 bytes, but in their quest to increase the storage capacity of drives, manufacturers have started moving to a much more efficient 4 Kbytes sector size.
This isn’t much of a problem aside from the fact that older operating systems don’t handle 4K sectors drives very well.
The vast majority of Macs update to mac OS Sierra without any adverse incident.
Sometimes when users attempt to download mac OS Sierra from the Mac App Store they will confront a “An error has occurred” red message and the download stops.
Some users do this without knowing the potential harm to drive while some do this due to other reasons, say power failure.Super Duper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless.Its incredibly clear, friendly interface is understandable, easy to use, and Super Duper's built-in scheduler makes it trivial to back up automatically.The green drives offer real advantages in terms of power savings and cooler operating temperatures, both things that WHS users tend to appreciate since our servers are often running 24/7.However, all of these ‘green’ features aren’t necessarily ideal for running in a server environment (see Step 1 below for an example.)
