Internal Hard Drive Died - Now replaced - Disk Utility Internal Error
When using the original system disk to install OSX the new hard drive isn't recognised even though I have formatted it for an intel based mac (GUID Partition, Extended Journaled etc) using my imac . When launching Disk Utility from the system disk and trying to erase/partion the drive, I get the following error message "Disk Utility Internal Error - Disk Utility has lost its connection with the Disk Management Tool...". When connected to my imac using a converter it appears on my desktop. Any help would be greatly appreciated. The macbook in question is a 2006 (white). PLEASE HELP.....
Hi - Thanks for your reply. I have tried that but it still doesn't work. I have had a look around online for the past couple of hours and I found a post that said that newer hard drives can't be recognised by an original 10.4 osx system disk. I would need to find a copy of 10.5 to install OSX on a new hard drive. I dont know if that's true because I dont have a copy of 10.5. Any thoughts would be appreciated!

Internal hard drive/repair: SMART status; Disk Utility, Tech Tool & More
machine: 12" PowerBook 1.5 GHz PowerPC G4 (Aluminium) with 80GB internal HD
internal hard drive (original): Hitachi Travelstar 5K100 series HTS541080G9AT00
hard drive firmware: MB4AA5AJ
ATA version: 6
ATA standard: ATA/ATAPI-6 T13 1410D revision 3a
I have monitored the SMART status etc. of my internal drive with smartmontools for some time. Occasionally, I would see an error or a failed self-test but later testing always succeeded and things did not seem to be problematic.
At the beginning of this week, I started to see a lot of failed self-tests (though some still passed), a rising number of bad ("pending") sectors and reallocation attempts (though no reallocated sectors) and various other errors. The computer seemed to have trouble reading from the disk at times and Carbon Copy Cloner reported two I/O errors when cloning (a later clone succeeded). fsck showed errors although running fsck -fy repeatedly seemed to resolve them.
The Apple hardware tests initially reported an error (2STF/8/3:ATA-100 ata-6-Master) but I hadn't realised I should disconnect peripherals before running it so I did that and repeated the test which found no issues. I ran the extended test a total of three times with no errors.
As I continued to have problems, I booted from my clone and had Disk Utility wipe the drive by writing zeros to it. (I thought trying to get it to write everywhere would either finish the drive off or force it to reallocate the bad blocks. As I understand it, in normal use, the drive won't reallocate the blocks unless it can recover the data in the hopes of reading it at a later time.)
I then continued monitoring the disk using smartmontools. At this point, short self-tests succeed but extended self-tests "disappear". They don't fail, they simply vanish. They begin and smartctl shows the test in progress but then no error or result is logged - it is as if the test was never run. The first time I did this, I got an error saying the SMART attributes could not be read but subsequent tests do not trigger even an error. Short self-tests continue to pass.
There are now (according to SMART) zero bad ("pending") sectors but zero reallocated sectors, which seems odd. The raw read error rate fluctuates (zero one minute, many thousands a while later) although I am not sure it did not do this before.
Disk Utility claims the disk does not support SMART status even though smartctl clearly shows it does. Disk Utility claims the volume is "OK".
I ran Tech Tool Deluxe 3.04 from CD and 3.1.1 from my clone. In both cases, I ran all available tests on the drive. No problems were found.
I am seeing some problems even while booted from my clone - yesterday, the system froze completely and I had to force a shut-down by switching off the power (fsck then found a minor error but repaired it). Just before this happened, I was unable to mount a disk image and was trying to rectify the situation when the system froze. It is possible that the errors fsck corrected were implicated in the freeze, rather than caused by it, since Disk Utility found and repaired similar errors for the other two clones I have (on different partitions of my external drive - yes, I know this is sub-optimal).
Here is some current output from smartmontools:

Self-tests 1-8 were all run after I erased the disk. The others were run before I did so. Not listed are the extended self-tests I've started since erasing which, as I say, have simply disappeared.
The checksum error regarding the log is normal for this disk. At least, I've got that error ever since I started using smartmontools for monitoring so I assume it is normal. (I installed this version of the software in about April 2008 and have used it since.) Also, starting offline testing has never succeeded on this disk (I think I checked into this at the time but can't quite remember - this is not new, anyway).
Questions
how should I interpret all this? (Why does Disk Utility say SMART is not supported while smartctl clearly shows it is at the same time? Why do the extended tests simply vanish? Is the drive definitely dying?) I do not want to replace the disk unless I absolutely have to because I understand that replacing disks in 12" PBs is no small matter and cost is an issue. I do not want to replace the machine unless I have to because cost is an issue and, also, I really like this computer and have no idea what I would want in its place, even if expense were no obstacle.
if it isn't clear whether the drive is dying or not, is there some further strategy I can use to establish this?
if the drive is dying, is a machine of this age worth repairing and, if it is, under what circumstances is it worth doing so? For example, it might be worth doing if you can do the job yourself, but that might be quite impractical for non-expert (not to mention, inexpert) users.
if there is a hardware problem (which I obviously think is very, very probable at this point), is it definitely a dying hard drive? (I've seen people write ominous things about disk controllers etc. which I gather are more serious - or less repairable - than a "mere" dying disk.)
what questions should I be asking you and what are the answers to those questions?!
Many thanks for your patience in reading this far.
- cfrThe 12" PB internals are a bit more complex, for PB's. If you don't want to replace the hard drive yourself or pay someone to install it, you could always get an external firewire hard drive, and use it to boot from and for general usage. Would have to be firewire, since the PB won't book from a USB device. One example of what you could get is a 160GB external hard drive: http://eshop.macsales.com/item/Other%20World%20Computing/MS4U5160GB8/ . All the choices with that case are listed here: http://eshop.macsales.com/shop/firewire/on-the-go
Have you called any Apple Authorized Service Providers to see what they would charge to install a drive for you? Whether you bought it or they supplied it? You can find a local one in the US at http://www.apple.com/buy/locator/service/ -
New internal hard drive not seen in disk utility
Hi
I replaced my hard drive with a western digital black edition but when I use it as an internal it is not seen by the disk utility.
I have installed and booked from the new drive using USB so it doesn't seem faulty.
When I use the old drive as an internal it works so I don't know what's going wrong.
I have had a look at similar problems but nothing I have tried has helped.It may be the internal connecting cable that is the problem. If you can install the new HDD in an enclosure, connect it to the MBP, then see if you recognize it using the OSX installation disk. If so, the internal connector should be replaced.
Ciao. -
Finder reports all internal hard drives as zero kb, disk utility correct
After upgrading to 10.5.3 finder is reporting internal HD's as zero KB in size and will not allow files to be coppied to them. Very Bad. Disk utility reports proper size and utilization. Does anyone have suggestions of where to start. File permissions have been repaired, before and after OS upgrade. Upgrade done from download not software update.
Also USB subsystem appears to lock up occasionally disabling mouse and keyboard, both via ADC monitor and tower connections. Motherboard battery is depleted, though I thought this would only affect system time, could it be creating other issues?I also just had this problem. jdisk reports 83gigs used of 300GBs, finder reports 299GBs used.

When I try to use the internal hard drive as a scratch disk I get this error "unable to set scratch disk- the selected directory is on write protect or non-writable media. Any ideas on how to fix this. It only happens in fcp.
By internal, I assume you're referring to your systems (boot) drive. Is it, by chance, a partitioned dive?
Also…although many people successfully use their systems drives as scratch disks, over time you'll have better results using a dedicated drive for your media.
Good luck.

After a startup problem with my macbook pro i put it as slave and formatted the internal Hard drive. Now i want to install OS X Mavericks from USB
How can i do that?What did you "put as slave?" What Mac model do you have, exactly?

The backup files for my devices are saved to my internal hard drive. I have a small internal hard drive and would like them to be saved to an external drive. How can I change where iTunes automatically backs up to?
This has nothing to do with iTunes as iTunes provides no way to move or relocate the backup files.
A search of google or the fourms would reveal ways to create a folder link to relocate the physical location where the files are stored. -
Hard crash now hard drive not recognized in disk utility.
During a virus scan the Macbook froze up now the computer does not seem to be accessing the hard drive. Tried to reinstall Leopard but the internal hard drive is not recognized (same is true when we tried to use Disk Utility). It will not start in safe mode either. Does this sound like a fried hard drive or maybe a corrupted drive that might be repairable with DiskWarrior? Any thoughts would be appreciated.
If the A/V you were using was Norton/Symantec, the drive may be OK. Norton is a virus.
Burn a Ununtu CD and see if you can boot into it and look at the drive before giving up on it. -
How to move an iTunes library from the internal hard drive to another bootable disk.
I got two Mac OS X installations on my i Mac system. One on the internal hard drive (320 Gb), that has been there since the iMac was bought 3 years ago, upgraded to Lion on 2 August. (call that INT) . I have a USB external drive, and recently bought a firewire Lacie external drive (2Tb), so to boot from there when I can, with hard drive space getting tight this year. I successfully installed another copy of Lion on LACIE.
Then I went to work to transfer my iTunes library, which the media files were optioned to store on the USB drive. Intending to transfer both the music and video files, and the megadata ( playlists, ratings, playcounts ) I found the media files and the iTunes library file and the .xml document in my iTunes folder from INT. I made a new folder in the USB drive, and copied the contents from the old iTunes folder to that new folder. I re-started in LACIE, and found my empty iTunes folder. I copied over to the new iTunes folder, then opened iTunes. My eyes saw the music library to the same number of items, with the playlists etc showing.
However, I tried to sync an iPod Nano, and a window came up saying 100 songs could not be copied to the iPod because they could not be found. After ejecting the iPod I tried to play a song from iTunes, and the screen filled with exclamation points. A small window came up, asking for a password to open "sparsebundle" and my name. I entered my password for the administrator's log-in and it said try again with the password. Without knowing what password to put in, I clicked Cancel, and got another small window asking to locate the file. Then clicked Cancel again, not knowing where to search. All the media folders were showing after quitting iTunes and opening Finder .
I re-booted into INT, and opened iTunes. The library was still there. I synced my iPod again, ejected it, played 3 songs on the iPod, synced again, ejected it again, and opened the playlist "Recently Played". It showed up okay with no problems. So my iTunes library in INT is alright.
Has anyone got any idea how to make the transfer into LACIE and get it running alright, or what went wrong with what I did ?
In the meantime I will empty my LACIE iTunes library folder's contents to the trash, and securily empty the trash .Solved the issue without using the trash . I tried to consolidate the library in LACIE, then clicked on any exclamation-mark song and tried to locate the file. Repeating those steps 3 or 4 times cleared it up. That was confirmed when I synced the entire library on a iPod Classic, and showed up no problems after syncing the Nano.
What went wrong was perhaps to fail to consolidate the library at first . -
Without any success, I cannot get my hard drive to work in disk utilities. I am able to see the disk in the upper left hand column, but when trying to initiliaze the software always reads operation not supported. Any ideas?
You probably have too new a hard disk. Contact the hard disk manufacturer and ask what jumper setting is needed to drop to 1.5 Gbps SATA speed.
Either that, or return the disk, and go to http://www.macsales.com/
They can be sure to equip you with a proper hard disk.
Note formatting is key as well:

Replacement hard drive not shown in Disk Utility
So I just finished installing a replacement hard drive for my PB 12". I got a Seagate 2.5" ATA Momentus 5400 etc as per my previous thread. But after firing it up from the install disk, the new volume fails to show up. Anyone else had this problem? And fixed it? Opening up the case again now...
Don't know if your problem solved. Had the same thing happen to me. Was told that new HD was bad (unlikely), Logic board was bad (disaster). Then finally was tole by another tech (OWC) that it sounded like a bad cable connection. Took it apart again and reseated both ends of HD cable a couple of times. Started up and the HD recognized by disk utility. Works great since. Hope your problem as simple as mine.

I have a MacBook Pro 13.3 inch from 2010. It came with 160/SD. I replaced it 3 years ago with a 750GB Seagate which just died per Apple genius. BUt, need to replace it now. Can I replace with a 1TB or only another 750GB?
it will hold even a 12.5mm thick 1.5TB HD
most 1TB drives are 9.5mm thick
It will NOT however hold a 15.2mm HD.
Typical bare 2.5" hard drives. 7mm left (250-500gig), 9.5mm right (500gig-1TB), and 15.2mm 4 platter drive at back (2TB) -
Hard drive not found in Disk Utility
Hello there. I wonder if anyone would be so kind to assist.
Bought a second hand Macbook. Had 80gb and worked fine on Leopard. Bought a new 320gb SATA, replacing the 80gb.
I have a Leopard upgrade disc and a Tiger full install 2-disc set. I insert Tiger and the Macbook advises that I am unable to install this software on to this hard drive. As the hard drive wasnt MAC formatted I guess I need to that first> I enter Disk Utility but cannot see my new HD (only the DVD drive where Tiger is at).
Any ideas?Drive is SATA II. No jumper settings as I had already checked.
Have eventually got round this very tedious problem. 320gb was not recognisable at all as you well know. Attached it to a caddy and used a Macbook Pro to see it. Couldn't find it. I attached it to a Windows machine and it got recognised. Re-attached it to the Macbook Pro (which now recognised it) and I formatted the 320gb into GUID format. The original 80gb which still worked had Leopard on it. I put that back into the Macbook and attached the 320gb externally via a USB caddy. Inserted Leopard DVD disc followed instructions and I let it restart. On restart it asks me the location of where to install and I chose the partition I created on the 320gb. Leopard was installed externally.
Reattached the 320gb back onto my Macbook and it worked. 6hrs of frustration but I got there in the end.
If anyone needs to remove the L-shaped panel from the battery bay from a Macbook I can do it free of charge. I can do that job blindfolded! -
New internal hard drive and now cannot migrate from back up
Took my MacBook Pro in yesterday to have it looked and found out hard drive was failing. Had already backed up via Time Machine onto my iomega external drive before I took my laptop to Apple store. I have been backing up for several years to the iomega drive. Got my MacBook Pro back today, and brought it home--awesome work by Apple store, even had it done yesterday before I made it back home from dropping it off.
So, here is the deal, turned it on, went through the steps required and got to the migration part. It recognizes that my iomega drive is connected to the laptop as the icon is on my desktop. However, the migration assistance cannot find the drive and just keeps spinning. Any suggestions before I set up another genius bar appointment?
Thanks

In my case I backed up my old internal hd to my new external 1 TB hd.
Surely you mean you used +Setup Assistant+ or +Migration Assistant+ to transfer the data? Or a "clone" via CarbonCopyCloner, SuperDuper, or Disk Utility?
Now it appears TM wants to ADD the contents of my new internal hd to those already backed up(another 220 gb).
Yes. As posted, to TM it's a new, different drive. TM will back it up. You cannot prevent it.
I wonder if I need to format the new drive and start over??
Yes, that's probably your best bet. -
External hard drive not visible in disk utility or finder
Hi all,
I have had a good look through previous discussions and I can't seem to find an issue relevant to mine.
My external hard drive has 2 partitions (1 time machine back up, 1 general hard drive). The issue is that the HD is running when it is plugged in however it is not visible in either disk utility or finder.
I am running OS X 10.10 (Yosemite) on a 2010 MacBook Pro. I also have parallels desktop running windows 7. When I boot windows and plug in the HD I usually get the option to mount the HD to either OS X or Windows. With this issue the option window appears for a split second (not enough time to select either) and then disappears. It seems that the HD may be ejecting itself as soon as it is registered by the computer. I have tried using a different power cable for the HD and also a different usb cable, this doesn't help.
The external HD is a Samsung D3 Station, which i have had for 6 months now and never had an issue with.
Any help is appreciated
Thanks,
BruceAn update for anyone who can help me:
I have tried the external hard drive in other computers (mac and windows), each time I get the same problem above.
I have removed the HD from the enclosure and purchased a docking station for it (3.5" SATA). When I plug it in to the laptop it disconnects itself straight away before it is visible. With the windows computers it installs the drivers and says that the device is ready to use, then disconnects before it shows up.
As the HD is not visible there is no option to re-format or anything.
This is very frustrating as I was using the HD with no issues and it randomly disconnected and I have not been able to access since.
Thanks in advance for any help.
Bruce
