    I have been noticing a slow down on my 2011 iMac also have had to force quit applications and reboot to stop the spinning ball. I am considering reloading but would like to verify I don't have a HDD failing. I am a PC tech and would usually just run sea tools for windows or other OEM test. I have run the short diagnostics off the second cd and first aid, both found nothing. Is there a tool that will just run a thorough test on the HDD? Free would be great but would consider paid.

    I do have a up to date time machine backup and an few month old image of the drive.

    It won't do anything about the HDD, but run etrecheck - does nice diagnostics on OS-related issues - donation ware - http://www.etrecheck.com

    Firstly, you should search the system log for messages indicative of a faulty disc:

    Note: The following procedure must be performed on an OS X user account that has administrative privileges.

    1. Open Terminal.
    2. Enter the following:

      syslog -k Sender kernel -k Message RCeq "corestorage|disk|jnl" -k Time ge -1w

    If no such messages exist, then examine the disc's SMART attributes using smartmontools or SMART Utility.

    This message indicates that disk2 may be faulty; however, disk2 is probably an external disc.

    What is the output of the following command?:

    diskutil list; diskutil info /dev/disk2

    Yes, disk2 is an external disc.

    By the way, does the issue still occur while all of your external discs are disconnected?

    I was noticing some slowdowns before I purchased the external drive, I bought the external to make sure I had good backups.
