I have a mid-2010 27" Quad Core i5 iMac running 10.8.3. Startup disk recognizes the primary hard drive as a startup volume but will not boot from it. Have tried zapping PRAM, ran disk utility. No errors reported Any thoughts?

My bad Eric. The startup preference recognizes the primary as a 10.8.3 startup volume but when u select it the system does not boot. I can only boot from my external backup drive

Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
So to sum up, the symptoms I'm seeing:
MacBook Pro CAN see internal SATA hard drives.
MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

UPDATE: An interesting development!
I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
Onward!

Need to erase hard drive and reinstall system on iMac but have misplaced original install disks. Tried to use a my copy of Snow lepord 10.6 from my Mac pro but will not boot. Can original install disks be replaced. Thanks

Need to erase hard drive and reinstall system on iMac but have misplaced original install disks. Tried to use a my copy of Snow lepord 10.6 from my Mac Pro but will not boot. Can original install disks be replaced. Thanks

Yes the original Install Discs can be replaced for a nominal fee. Call AppleCare, you will need a credit card and the serial number of the machine. You can use the AppleCare Contact Info for the phone number on your part of the planet.

I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating sys

I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating system. I do not have a back up of all my applications, my garageband music and other things. I also do not have time capsule set up on this machine, but I do have a 2 TB time capsule.
Is there anyway to back up this corrupted drive so I can restore my applications later?

There's an old saying. If you don't have a backup disc, then there must be nothing important to backup. That's just lesson #1. Lesson #2 is to never interrupt a software update. Not a good thing.
OK, I'm sure you know this. It just upsets me to read your story, knowing you have a lot of important stuff on your hard drive, and didn't use time machine.
You're pretty much in a bad place. My only hope for you is to boot to your Installation Disc, then using disk utility see if you can save the internal hard drive (by fixing what can be fixed). You might be able to see your user folder and some of your apps. I wouldn't even consider copying the library, because who knows what's been corrupted in there.
Good luck.

I want to install a new hard drive on my 2008 MacBook but do not have the instillation discs that came with my computer. Can I use instillation discs from a 2009 or 2010 MacBook?

I want to install a new hard drive on my 2008 MacBook but do not have the instillation discs that came with my computer. Can I use instillation discs from a 2009 or 2010 MacBook? The hard drive I am planning to install is a WD Scorpio Black 500GB SATA 2.5'' internal hard drive.

Sometimes they do work - i've done it before. I have a late 2008 Macbook Uni and used the install dvd of my 2009 Macbook White and it worked.
Why not just clone your hard drive? It'll save you a lot of time doing a clone rather than doing a clean install.
Unless you're having issues with your old set up or your old hard drive is dead.
You can download Carbon Copy Cloner - install your new hard drive in a external usb enclosure (around $10) and clone fromt here then test it before you install it in your Macbook.
Once you've done the swap, you can install your old hard drive in the USB enclosure and use it as a backup drive.
Good luck

Intel Xserve will NOT boot from hard disk drive

I have two Intel Xserves 2.0 QC machines
I have tried to re-install version 10.4.11 OS (don't ask) onto a Hard disk drive that is in a Disk drive caddy and inserted in the machine.
When booting from The installation DVD media
The disk is seen by the "Disk Utility" (the disk is partitioned as GUID boot) and the installation proceeds to the disk.
Once the first pass of the installation is complete and the system reboots, the system shows the folder and ? mark.
If I boot and hold "ALT" key to view all avaialble boot options the Hard Disk Drive does NOT appear as valid boot disk.
It does show, the still inserted Installation DVD.
I CAN boot from an external firewire drive and the Hard disk drive is visible to the OS once logged in.
I have tried different caddy postions (left, middle and right)
I have tried bona fide Apple supplied Disk drives
I have tried various different caddies
I have tried installing Operating System 10.5.* and 10.6.8 server
I have run SMC reset and system reset
But still I cannot boot off from any Hard Disk Drive inserted in a caddy at the front of the system.
Has anyone seen this behaviour?
Is it fixable?
Do I have replace something like the Hard Disk Drive back plane circuit board? Or even the main logic board?
I have now run out of ideas and cannot find any help in discussions or just googling.
ANY help would be very appreciated
Regards
Tony

Antonio Hi !
QC = Quad core or QX as it is written on the "pull out" serial number tab at rear of system
I have 3 late 2006 Intel xserves
On my intial posting I declared 2 were 2.0 machines - when I was trying to be concise
2 of the macines are 2.66 systems and 1 is 2.0 system - all are QX machines
the 2.0 and 1 of the 2.66 will NOT boot from the ADM and disk inside the system - whereas the other 2.66 system will.
I have many different Caddies and these have different product/model number labels
603-9965
603-9545
603-9796
these are marked "intel SATA"
The 80Gb was only one of the drives tested - I have used Seagate 400Gb 750Gb and 1Tb - all of which have been used in systems at one time or another
and as I said the drives ARE visible once the operating system (either installation DVD or external firewire are booted from) - they are just NOT visible when the system is searching for boot media.
Thanks for the guide - I will look through that and continue to try and find an answer

IMac will not boot from any mode except Target Disk

I have an Early 2008 Penryn iMac 24" MB398LL/A running OS X 10.7.4 (see specs below) that will not boot from ANY mode, It also has several strange vertical bars from top to bottom on the screen. They are about 10 px wide, with some pixels empty and looks a bit like a barcode if you squint at it.
I have tried Safe Boot, Force Boot, DVD Boot, FireWire/USB Boot, and it always gets to the same point. It gets to the apple screen with the spinning gear and then after about 8 seconds it freezes. The only way it works at all is in Target Disk Mode. It pops right up on my Macbook Pro and I was able to grab all my info!
I have run Disc Utilities and Tech Tool on it many times from my MBP and it passes every test.
I reformatted the HD and installed 10.7 again, it still freezes up at the same point.
I have tried using Single User mode and every time have had to run /sbin/fsck -fy twice because it always says the disk is ok but it was modified on the first pass.
I thought maybe it had a bad video card or logic board but and I ran the Apple Hardware Test on many occasions and it always passes. Recently I was told about Loop Mode and just completed running the AHT for just over 30 hours without any errors at all.
UPDATE...
Strange Part… I tried installing Mountain Lion in Target Disk Mode and everything went smoothly. When it restarted on its own the lines on the screen were gone for the moment, but the Mac still freezes up on the spinning gear and immediately restarts on its own. I have run every thing listed above on it and still nothing. Sometimes the lines reappear then in two more starts they are gone.
I did manage to have it start one time got a copy of the the error report (its at the bottom too) The Mac ran for at least 30 minutes with no problems, then the screen went crazy a few seconds and it became unresponsive. The mouse moved but that was all it could do. Now my iMac continually restarts itself, I don't have any more ideas, HELP!
Specs...

Hard disk not recognised - will not boot from cd & No FW Target Disk mode

hi,
some help would be greatly appreciated.
Some time ago i was switching internal hard drives around and wound up with a kernel panic of some sort (see my previous posts).
following on from this I have tried FW target disk mode with no success, and it will not boot from a retail Tiger install disc (this machine has tiger installed (i think!). I can't force a boot from the optical drive and i also can't even force it to eject the disc inside to try another install DVD/CD (I have panther discs lying around also).
when i start up with the c key nothing happens, but when i start up with the alt/option key i get a closed padlock symbol, password entry field and a "right facing arrow" button.
anyone got any clues with this? i'm guessing it could either and/or be an internal hard drive ribbon failure (i have swapped internal HDs multiple times in this machine, which can't be good for it) or the familiar PRAM problem (although why would it not boot from an install DVD if this was the case?). I have changed the power supply unit in the past due to having a power cable snap off inside the original one - damage to PRAM caused by this?
help would be muchly appreciated!
Jesse

Hi, Jesse. Remove the hard drive and its cable, then see whether you can start up from a CD or DVD. If that works, replace your hard drive cable.

Macbook Pro will not load OS and will not boot from Install Disk

When I try to turn on my macbook pro it goes to the gray logo screen with the spinning gear however it does not progress from there and then after several minutes it proceeds to restart itself and the same process repeats itself. I have tried to boot into single user mode with success and have run /sbin/fsck -fy and that has returned that the volume appears to be ok. However, when I hit reboot it returns to the same process of the gray screen and spinning gear to black screen which repeats. When I boot into verbose mode it progresses to AppleYukon2: RxRingSize <= 1024, TxRingSize 256, RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328 then it stalls for several minutes and then it shows continuing
synchronizing disks... Killing processes
then it says some other stuff to fast to read.
When I try to boot from the install disk it will not boot from holding the c key it goes through the same aforementioned cycle. When using option to boot I can see the Disk then when I select it the cycle happens again.
Also I have XP installed and I am able to boot into that successfully. Any help would be greatly appreciated.
Not sure if I left anything out

Welcome to Apple Discussions.
Do you have multiple Accounts defined on that system? The last time you successfully were running, did you run from the Account with Administrator privileges?
Do you have another computer from which you could boot and connect the Macbook Pro in Target Disk Mode to take a look at the drive from your working machine? Perhaps you can run Disk Utility from the working machine and point to the hard disk on the failing Macbook Pro.

Macbook pro 17 inch early 2008 will not boot from disk

My macbook pro will not boot from from disk. I am running 10.6.8. Tried loading the disk that came with system holding down the C and you can here the drive working. It came back and said to restart computer by holding down the power button and poering it back up. Tried that and nothing. The software I tried to load is 10.5.4 Also tried loading os x snow leopard 10.6. Same thing happens.

Have you reset the SMC? If not, try that.
Intel-based Macs: Resetting the System Management Controller (SMC)
If you've done that, and it didn't help, then launch the Terminal application by entering the first few letters of its name into a Spotlight search. Copy or drag -- do not type -- the line below into the Terminal window, then press return:
pmset -g
Post any lines of output that appear below what you entered -- the text, please, not a screenshot. Then repeat with the following line:
pmset -g assertion

I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Mac

I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Machine, there are only about 5 backups recorded on the ext. hard drive. There were many more before. Any idea what happened and if I have to buy a new back up hard drive?

Hallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.
regards - Alan

I have 2 itunes accounts. I can no longer use my first one for purchases so I had to start a new one and it will not sync from my new one without deleting everything on my same ipod from my previous account. How do I sync between both accounts?

You may not have the iPod's Music tab set up in iTunes, which is how you tell iTunes how to automatically sync your iPod.
Select the iPod in iTunes. There is a row of "tabs" (starting with Summary). Click on Music there.
To use automatic syncing, the checkbox for Sync Music is checked. Below that, you can choose to sync Entire music library, if it fits. Otherwise, you can choose to sync Select playlists, artists, albums, and genres.
With the latter choice, you can create a selection of songs to sync to the iPod by selecting (checkmarking) playlists, artists, albums, and/or genres on the Music tab. For example, you can make a playlist in iTunes with all the songs you want on the iPod. That new album needs to be on that playlist, if you want those songs synced to the iPod. On the Music tab, checkmark that playlist.
When you Apply the change, your selection of songs sync to the iPod (replacing its existing content). Going forward, any changes in the iTunes Music library that are related to your selection of songs on the Music tab sync automatically to the iPod when you connect it, or when you click Sync.
Therefore, if you create a playlist with songs you want on the iPod, and select it on the iPod's Music tab, you can simply update that playlist in iTunes (add and remove songs), and those changes sync to the iPod automatically at the next opportunity.

I have a mid-2010 27" Quad Core i5 iMac running 10.8.3. Startup disk recognizes the primary hard drive as a startup volume but will not boot from it. Have tried zapping PRAM, ran disk utility. No errors reported Any thoughts?
