Just received an Email from Apple regarding the subject matter for 21.5 and 27 inch iMacs purchased between May 2011 and July 2011.
The pertinent information Hot Link URL gives an "URL is not syntactically valid" response when double clicked.
A Copy and Paste of the full URL plus additional deletions of invalid quotes etc still provides no connection to the information.
If anyone has received a valid URL for this Hot Link could you please post the URL in this thread.
Here is the URL that I received in my email:
And a screenshot of the page it takes me to:
Hope that helps. My two cents is...I haven't noticed any problems with my HD, and I do Time Machine backups daily, so I intend to ride it out. They will repair these drives for another year, and I have Applecare for three, so I see no need to hit the panic button right away if I'm not having issues. Like the email said, it's a small percentage.
