Host of problems - is the HD failing?

Question

I have an iMac Mid 2010, 3.06 GHz i3, 8 GB 1333 MHz.  Running Yosemite.Since I installed Yosemite I have been having a HOST of problems.  The most significant being a Sleep Wake issue - the computer will not wake up from sleep or just hangs forever in some kind of sleep purgatory.  I have reset the PRAM to try to fix that to no avail.  I also turned the computer sleep to never.  Still doing it.So I am having to restart with the power button on a regular basis. No bueno.  Then I get to watch it start up.  FOREVER.  My Outlook crashes at least once a day, often more.  Probably would be even more if I didn&#x27;t have to restart the computer so frequently. The whole system is working slowly generally.  And for a long time - before Yosemite - I have been having flash issues.  Videos play for a few seconds and then hang buffering forever.  I can&#x27;t watch videos at all.Then, just today, my computer just started freezing in the middle of using it.  The mouse will move the cursor around the screen but I cannot select anything and option command esc will not pull up the force quit screen.I regularly verify and repair disk permissions. I&#x27;m no Mac genius and I don&#x27;t know what else to do!!   Is this a sign that my hard drive is failing?  Are these all symptoms of one issue or is it a bunch of things I need to address?TIA!Here is my EtreCheckEtreCheck version: 2.1.8 (121)Report generated February 25, 2015 at 9:35:25 AM CSTDownload EtreCheck from http://etresoft.com/etrecheckClick the [Click for support] links for help with non-Apple products.Click the [Click for details] links for more information about that line.Hardware Information: ℹ️    iMac (21.5-inch, Mid 2010) (Technical Specifications)    iMac - model: iMac11,2    1 3.06 GHz Intel Core i3 CPU: 2-core    8 GB RAM Upgradeable        BANK 0/DIMM0            Empty           BANK 1/DIMM0            Empty           BANK 0/DIMM1            4 GB DDR3 1333 MHz ok        BANK 1/DIMM1            4 GB DDR3 1333 MHz ok    Bluetooth: Old - Handoff/Airdrop2 not supported    Wireless:  en1: 802.11 a/b/g/nVideo Information: ℹ️    ATI Radeon HD 4670 - VRAM: 256 MB        iMac 1920 x 1080System Software: ℹ️    OS X 10.10.1 (14B25) - Time since boot: 0:28:18Disk Information: ℹ️    SAMSUNG HD502HJ disk0 : (500.11 GB)        EFI (disk0s1) &lt;not mounted&gt; : 210 MB         Macintosh HD (disk0s2) / : 499.25 GB (293.34 GB free)        Recovery HD (disk0s3) &lt;not mounted&gt;  [Recovery]: 650 MB     HL-DT-STDVDRW  GA32N  USB Information: ℹ️    Mitsumi Electric Apple Optical USB Mouse     Western Digital My Book 1110 999.5 GB        EFI (disk1s1) &lt;not mounted&gt; : 210 MB         Time Machine (disk1s2) /Volumes/Time Machine : 600.94 GB (216.28 GB free)        Storage (disk1s3) /Volumes/Storage : 398.08 GB (213.44 GB free)    Apple Inc.

Step 1Take all the applicable steps in this support article. That&#x27;s the starting point for any further efforts to solve the problem. Please read the whole article carefully and don&#x27;t skip any of the steps, including the ones under the heading Additional troubleshooting. If you don&#x27;t understand any of the steps, ask for guidance.Also note that if you replaced the internal hard drive with an SSD, or if you&#x27;re starting up from an external SSD, then that device may be causing the problem. Check the SSD manufacturer&#x27;s website for a firmware update. The only solution may be to reinstall the original drive or avoid sleep altogether.Step 2If you&#x27;re running OS X 10.8.5 or earlier, from the menu bar select           ▹ System Preferences... ▹ AccessibilityIf the checkbox at the bottom marked          Enable access for assistive devicesis checked, uncheck it and test.If you&#x27;re running OS X 10.9 or later, select           ▹ System Preferences... ▹ Security &amp; Privacy ▹ Privacy ▹ AccessibilityIf any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.Step 3In the Energy Saver pane of System Preferences, uncheck the box marked          Put hard disks to sleep when possibleStep 4If you don&#x27;t already have a current backup, back up all data, then reinstall the OS.* You don&#x27;t need to erase the startup volume, and you won&#x27;t need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.If you installed the Java runtime distributed by Apple and still need it, you&#x27;ll have to reinstall it. The same goes for Xcode. All other data will be preserved.*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.Step 5This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.Launch the Console application in any of the following ways:☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.☞ Open LaunchPad and start typing the name.In the Console window, select          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage MessagesIn the search box in the window&#x27;s toolbar, enter "powerd" (without the quotes.)You may see one or more lines like this:com.apple.message.signature: Platform FailureIf you do see that, and you did everything in the preceeding steps, then you&#x27;re dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.Step 6In the Console window, select          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports(not Diagnostic and Usage Messages) from the log list on the left. If you don&#x27;t see that heading, select          View ▹ Show Log Listfrom the menu bar.There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down.You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.I know the report is long, maybe several hundred lines. Please post all of it anyway.

Well.  Now my am is hung up in the middle of the OS reinstall.  I&#x27;m about to just give up and use it as a monitor for a new mini.

Linc Davis · Answer

It sounds like you have a hardware fault. Take the machine to be tested and if necessary repaired.

Thank you for all of your help Linc, I don&#x27;t want to seem ungrateful!  After the computer stalled out during the OS reinstall I restarted it and everything was fine.  I had unplugged my external HD during the diagnostic process.  I did everything on the list and it is showing no sleep wake failures through the Console or any platform failures.  It hasn&#x27;t had a sleep wake issue since either. So I guess my question is, Could my external HD be causing the issue?I haven&#x27;t been able to do a lot of work since I ran all the diagnostics because a lot of my files are on the external.Thanks again!

Linc Davis · Answer

Could my external HD be causing the issue?The only way to find out is to disconnect it and test.
