Other World Computing has a new blog post explaining that the new 2011 iMacs now rely on a 7-wire SATA power connector and Apple proprietary firmware on the main hard drive to monitor temperature. Remove or replace it, and the iMac’s fans run at full speed all the time. Boo on Apple for preventing owners from replacing the drive with one from any third-party vendor. follow link
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
New 2011 iMac Hard Drive Cannot Be Removed or Replaced
Nothing else will clear up any misconceptions.
If you are to add value and publish stuff worth reading, you'll do your own research, not just act like some technology parrot.
Yes, you pointed to OWC's coverage, but then you decided that Apple was guilty of something without checking the facts and said "Boo on Apple for preventing owners from replacing the drive with one from any third party vendor."
That's where you stepped over a line. You also stepped over a line in the title of the article. It is completely false. The hard drive can be removed and it can be replaced.
You want your advertising revenue, but want to take short cuts in earning it.
And you completely failed to mention that the pain and anguish of opening up an iMac is offset by a good thing that Apple did. It's called Thunderbolt.
If it's not your story, don't publish it.
