    Thanks, WZZZ.


    I was all set this morning for ordering a hard drive, but I just read through the guide on and it is a little more work than my enthusiasm let me see. :P


    I didn't even notice the need for Torx screwdrivers.


    I won't rush into this.


    I'll read through it another couple of times over the next few days (and contact the various manufacturers as you suggested). I'll see how confident I feel about this then.


    There are a few parts in the guide I am not sure I could manage.


    At worst, I will buy an external FireWire hard drive until I can take it to an Apple repair store.


    Thanks for all the help, guys.


    If you have anymore input, I welcome it.

    You can  buy the drive and have an Authorized Apple Repair service install it. Check with them first.

  • NeddySeagoon Level 1 Level 1 (5 points)

    Yes, that is a good.


    The last few times I have started up the iMac (from the external bootable drive) I have got a message saying "Mac OSX cannot repair Macintosh HD (which is the internal drive)" and for the last week I can hear a "shutdown" sound coming from the Mac.


    Can I run my iMac indefinitely from a bootable drive?


    Or will the iMac eventually stop running? Can I get the summer out of it?

  • WZZZ Level 6 Level 6 (12,775 points)

    Not sure of the answer to this. I have heard of certain scenarios of internal drive failure that prevented proper use of the external as the boot drive. In those cases, it may boot but doesn't function 100%. I don't remember right now just what that sticky scenario was. If I recall, the solution was to disconnect the internal completely. But of course if you could do that, you could just go ahead and replace it.


    Anyway, once booted from the external, you should go into Sys Prefs>Startup Disk and set the external as the startup drive. Then always have the external turned on before you boot the Mac. See how it goes.


    Maybe someone else will be able to chime in on this.

  • NeddySeagoon Level 1 Level 1 (5 points)

    Already set to that.


    I'm leaning towards attempting the replacement myself and if it goes pear shaped, then so be it, I can just make do until I get to a tech.


    Of course, I could that guide again in five minutes and change my mind again.

    Kappy, you mentioned finding info at mfg website re HD info. As a side note, how can I find out what name and model of HD I have inside my iMac? I look on DU and only see a bunch of numbers like: "1 TB ST31000528AS Media", and below that says it is "disk description" and Connection Bus says "SATA". I then tried to look on "System Information" and under "hardware" it only shows Model Name, iMac, and other things but I don't see any model or name of HD. Reason, I got note saying I probably am in list of those who have Seagate hard drives which may fail so I will get free replacement, but I like to see the name someplace before I haul my whole iMac in to store (and I first need to erase all and have to reinstall EVERYTHING on new HD-which scares me)! (I have backups going to an iomega external HD). Thanks for info, sorry if doesn't "fit" in here, but thot just info re HD might be ok to ask about instead of starting whole new area.

    It's this Seagate drive. But, note, the Apple OEM model will probably be different for temperature monitoring, depending on the model/year of your iMac.

    I have an iMac 21.5 inch, mid 2010 with 3.06 GHz Intel i3, 4GB DDR3.

    I have an Iomega Personal 1TB External, i am wanting to replace the 500GB hdd that is in the mac, would my external be a good replacement?

    It is having issues running on a usb port, the port is continuously getting replaced, i am wanting to put it into the computer to eliminate all issues with it.

    You are attempting to revive a 3 year old thread, I would recommend posting your own thread and asking your questions.
