Cannot resize internal disk Disk Utility

I was partitioning my drive but then Disk Utility became stuck, I force quitted it and tried to revert the changes it made. I managed the delete the half created partition but now when I try to extend my boot partition back to its normal size, it doesn't work.
I tried booting into recovery and using Disk Utility, there I was give the error "cannot unmount disk" I tried repairing it. still didn't solve the issue. If I need to restore from timemachine, how will i s

This worked for me: https://help.backblaze.com/entries/22395778-How-to-partition-a-Time-Machine-driv e
Basically, you have to turn off Time Machine automatic backups in System Preferences (and possibly restart Disk Utility) before the drag handle shows up.

Can't repair or partition internal hard disk with disk utility

Hi,
For the past couple months I've been trying to repair and (re)format my second internal hard disk. It stopped showing up on the desktop after I attempted to install leopard on it. Until then I'd had no problems with the disk for the two years I've had it Leopard installed fine on the other smaller internal disk. But the second disk only shows up in disk utilities - it doesn't have any volumes. I can't verity the disk because the button is greyed out as is the repair disk button.
S.M.A.R.T. Status shows "not supported".
Partition Map Scheme shows "unformatted".
Whenever I startup my computer I get a dialog box stating "The disk I have inserted is unreadable by this computer". I't referring to my 250gig internal disk. I read some posts here that suggested using OS 10.4 disk utility to format but that doesn't work either.
At this point I'm totally lost as are all the files I had on that disk - I initially erased it back when I attempted to install leopard on it. Does anybody have any ideas how to fix this?
Thanks for any and all help

Hi V.K.
Thanks for the advice. Luckily I don't have any data on it since I wiped it clean back when I attempted to install leopard on it a couple months ago. I'm really amazed that it only lasted two years compared to my 80gig which has been in use [daily] for at least five years. I hardly ever used the 250gig drive. I ordered another (500gig) drive from Western Digital which I expect to be here in a couple days. In the mean time I guess I'll get out my hammer.
Thanks for your help.

Disk Utility hangs while initializing internal hard disk in Core Duo iMac

I have a 20" Core Duo iMac. Recently the internal hard drive crashed ("invalid B-tree node size" or something reported when Disk Utility tries and fails to repair it). I have all my data on an external hard disk used as a Time Machine volume, so recovery is not my issue. Initially I picked the write zeroes once security option and chose to erase the internal hard disk. Realizing this would take too long, I clicked on skip, and Disk Utility appeared to hang. I quit and restarted Disk Utility, and chose the "don't erase" security option, but when I go to erase the drive it appears to hang while at the "partitioning" stage and doesn't seem to get any further. There is motion in the progress bar, but no additional progress after about an hour. Disk Utility shows the disk but no volumes underneath it (whereas immediately after the crash, it showed an unmountable volume labeled "disk0s2").
Why would Disk Utility be taking so long and not making any progress? How can I reformat this disk if Disk Utility is not able to? Incidentally, I am running the Disk Utility that comes with OS X 10.4.8, since that is the OS X version on my portable hard drive that I booted from. I also tried using Drive Genius to initialize the hard disk, but it also appeared to hang with no progress.

It is possible the drive has failed, but to be sure start by turning off the computer. Wait five minutes. Then do this:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Be sure to boot from the OS X installer DVD, not a backup clone.

Csound1, William & Sig .... thanks for taking the trouble to reply. I fear you are right - I'll need a new disk. I'm booked in at the Apple Genius Bar in Bordeaux, France on Wed ... quite a challenge as my French isn't great! The current internal disk is 500gb, does anyone know whether I can upgrade my 21.5" iMac (circa Oct-2009 vintage) to a larger size internal disk, 1Tb or even 2Tb? I already have one external 2Tb drive and another one on order (I have masses of media stored and more planned as I've just taken up photography). Seems a bit of a pain managing with only 500gb internal storage. OR, can you advise me on how I can store all my photos on my new 2Tb external drive - I can't seem to figure out how to set the path for iPhoto to see them (I can't even figure out where they are stored right now!). Same with iTunes, how do I set the default storage to the external drive (I moved everything manually and then imported them all from the new drive - it worked but seemed very convoluted). Any advice on how to manage multiple drives gratefully received. And thanks again for previous replies.

MacBook does not see internal hard disk

Sorry if this is already answered somewhere, but I have searched so many forums that my head is swimming!
My boyfriend connected a new USB drive to his MacBook, formatted the new disk, copied some backup data onto it. At some point, the MacBook hung, so he held down the power key until the MB turned off.
Each time we restart it now, we get the flashing-folder-with-question-mark, and Tiger won't boot.
I have tried almost all of the tips I can find, and was even willing to reinstall OS X, however... the MacBook does not appear to see it's internal hard disk. As such, I cannot perform first aid on the disk via booting to setup DVD, and I cannot reinstall OS X.
If I boot from the OS X install disk, and use Disk Utility, the MB only sees the CD-RW/DVD-RW drive and the install disc. No internal HD ever shows up.
Help! I am at a loss as to how to fix...

Let me guess: you're also experiencing a low clicking noise from the right side of your mac immediately after you turn it on, right? Same thing happened to me and others, in fact there are several threads on this subject already:
http://discussions.apple.com/thread.jspa?threadID=960977&start=0&tstart=0

My drive was done for, and no data could be saved. I ended up buying a new drive, and now I'm just hoping the same thing doesn't happen again. I'm beginning to get a sense that this problem is occurring on a more frequent level now that the 1st generation macbooks have reached their 1-year birthday, give or take. Let's hope Appel fesses up if it is indeed a design flaw.
Anyway, you most likely need a new drive. I just got a Hitachi Travelstar 250 gb for around 200$US, so they're quite cheap, and VERY easy to install, just 3 screws, slide it in, boot up, run disk utility, erase/format and you're good to go.

Unable to erase internal hard disk

Dear Mac Book Users
To begin with I got a problem of spinning wheel and grey screen, upon extensive research online i could,nt find any solution and everytime i tried to repair it with disk utility's first aid otion i got the following error:
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
There were a lot of errors wth permissions (upon clicking verify permissions) but the repair permissions button was greyed out.
Now all that is history and finally the only solution to get rid of the above problem was to back up my data to an external hd (WD-My passport) using the Restore option in disk utility. That worked well and all my data, the whole volume named MACINTOSH HD was copied to external hd and alsi now I am able to boot with this external hd.
Now the problem is that when i go to disk utility and try to erase the original internal hard disk details of which are as follows:
Disk Description :
ST9160314ASG Media
Total Capacity :
160.04 GB (1,60,04,18,85,696 Bytes)
Connection Bus :
SATA
Write Status :
Read/Write
Connection Type :
Internal
S.M.A.R.T. Status :
Not Supported
Partition Map Scheme :
GUID Partition Table
I get the error:
Volume Erase failed with the error:
File system formatter failed.
I want to know that has my hard disk crashed and if yes how to confirm it?
Also if it has crashed, now can i get a new hard disk with a greater capacity (let me know the maximum capacity) than my original 160gb. Are there any things i should keep in mind while buying a new one?

Re: How can I add a second internal hard disk to a Satellite Pro P200?

I have a Satellite Pro P200 with a single internal hard disk. There is a second bay under the computer for another internal hard disk but I have not been able to find any information about it. There is enough space for a 2.5" SATA drive but I cannot see a connector.
I contacted Dutch Toshiba Customer support who said that it was the official policy not to provide any information about a second hard internal disk. They also said that they would not supply any parts to make it possible.
Can anyone provide some more information?

Hello
I have the same notebook with the same situation. The fact is that covers and the construction for all P200 notebooks is the same but notebooks are delivered with different hardware platforms. Some models are delivered with two HDDs.
Other models (like yours and mine) are delivered with one HDD but without possibility for upgrade with second HDD.

Mac OSX wont reognise my internal hard disk drive

I have a problem where for some reason when I start up my Macbook Pro (intel core duo) it does not detect the internal hard disk drive at all. I have run a hardware test and it shows no problems whatsoever. I have tried resetting the PRAM etc and to no avail. Yesterday the system hung and I tried to force quit and it wouldn't do anything so eventually I held down the power key and when it tried to reboot this is the problem I was faced with (it would boot up with the "no entry" sign). I accepted complete defeat and went to completely re-install OSX however it doesn't even show the internal hard drive when I wait for it to give me install destinations. I had tried seeing the hard drive through disk utility however it only shows the install DVD and that's it in the sidebar. I resigned myself further to thinking either the logic board or the HDD had packed in all and I took it round to my brother in law to see if there is anything he could do without opening the machine (he is Oxford educated and writes programmes etc so is very knowledgable), now this is the part that has miffed us both, he started it up using a Linux disc and once running, Linux see's the hard drive with no problems. He has been able to access the HDD with absolutely no problems under Linux both reading and writing to it. I even took my Mac Mini round and he booted them both up in Linux and completely copied Mac OSX from the mini to the macbook pro but still when I try booting up its as if the HDD isn't even there. Why can Linux see the drive and not Mac OSX? Please don't be affraid to get very technical in your answers as they may mean nothing to me but will probably all make sense to my brother in Law. Any sugestions at all would be greatly accepted.

Dear mcdkev,
You guys may have made a big error cloning the Mini HD into the MBP. They both have very different drivers and hardware settings and their OS X versions are customized to fit the hardware. That is why each mac comes with it's own version of OS X and their backup disks. That's a reason why it did not work.
Ok, so now that you do not have any of the original info on the MBP try the following:
Use linux to scan the disk surface & repair any problems.
Reformat the drive as DOS or FAT 32. (I wouldn't go into any linux specific format unless you can "Apple" format it, which I don't think linux has that option.)
Now, the MBP should be able to see it's drive...
boot from the OS X DVD , from the Utilities menu choose Disk Utilities, partition the drive as GUI file system (in case the linux format made the drive a "system boot record", you do not want that... )
Then format the drive as "OS X Extended Journaled"
Now go back to install and install your original basic set of OS X (the factory default).
*If nothing works, please do take your MBP to the Apple store or to a certified tech before you do more damage to the drive and it becomes unusable ...*

Best Practice??? Change from internal boot disk to external disk

I have a mini running 10.5.6 server and it currently boots off it's internal disk. I was hoping to get some feedback/input from others on a good process to convert the system from it's internal boot disk to an external boot disk (firewire).
I wanted minimum downtime during the conversion and I of course, want a complete snapshot on the new boot disk. Lastly, I do not have a local keyboard and console on the system although I could connect one if it seemed to be much easier that way.
In general, I am thinking of the following:
1) Boot into the Leopard Server CD.
2) Use diskutility to Restore from the internal boot disk to the new external boot disk.
3) Choose the new boot disk as the startup disk.
4) Reboot onto new disk.
Is diskutility the best bet?? Meaning will it work this way if the drives are different sizes??
Should I try to clone the disk from the internal boot disk (assuming I shutoff services first) using SuperDuper or Carbon Copy Cloner?? But I believe they do not copy over all logfiles, etc..
Or does anyone have a quick overview of a methodology which they have done in the past or just are suggesting might be a better process than the ones I described??
In Summary:
1) From the CD, clone using diskutil and change boot disk
2) From the running OS, clone using SuperDuper or CCC and than reboot onto new disk
3) Something else??
Thank you in advance.

For cloning the machine you have the approach fine. Disk Utility is fine and booting from the CD is the best method. Simply use the restore method.
But why on earth would you want to boot from an external Firewire drive? First, there is the issue of speed. You have a mini, let's assume it is a one generation back Intel. It has an internal SATA drive on a 1.5 Gbps connection. You want to move that to a 400 Mbps Firewire bus? Next, beyond the speed issues, you have a persistence issue. You are taking the boot volume and moving into to a transitory bus. One of Firewire's greatest strengths is easy connection/disconnection. Persistence is not a strong point.
Next, if your plan is to move the boot volume to some form of a Firewire RAID, then you are even penalizing yourself more. The mini has one FireWire port. If you are using two devices and creating a mirror RAID, then you need to daisy chain. Talk about points of failure, asynchronous startup time, bus blocking, etc. Not wise.
Plus, I can not count how many external firewire devices have burnt up in the effort to have small footprints. Lacie and the "let's put a drive in a metal case with no fan" approach = melted drive. Western Digital and Lacie with the "let's make a completely un-reusable external power brick that either breaks in a small breeze or falls out when the heavy guy walks by the server" approach.
If you are looking at a Firewire RAID enclosure, then you are missing the objective of speed as you are limited by the 400 bus. It is nice to say that you have a four drive SATA 2 RAID case running a RAID 5, but you are defeating the purpose of why you bought the raid. The RAID 5 can provide an exponential increase in I/O performance. But that goes out the window because of the slow bus.
If your argument is that "this is a server and my bottleneck is Ethernet," that too does not hold up. You are likely running on a gigabyte network.
For system details check out http://developer.apple.com/documentation/HardwareDrivers/Conceptual/Macmini_0602 /Articles/architecture.html.
Take this with a grain of salt. You caught me on a grumpy day as yesterday I dealt with a melted external firewire drive.
My advice is buy real server class hardware. What is you objective? Drive redundancy? Capacity? A mini is a great dev server. Not a production server. This is your data. Presumably the data that makes your business function. Don't trust it to a single platter. And don't trust it to a consumer level, disposable system. I am not trying to malign the mini. It is a fine machine for its role. Its role however is not to be a production file server. Now as a web server, we are talking a different situation.
Ok, I am rambling. Hope this helps in some way.

I've got no internal hard disk?! Help!!

I've got a major problem with my eMac. When i switched it on, it gives me the flashing folder symbol indicating that my computer can't find the system. I put in my Panther disks, and when it comes to installing panther, it cannot find the hard disk at all. I ran disk utility, and that can't find the hard disk either. Does anyone have any suggestions, as to how i could fix my computer?

Ken -
Check out KBase Article 106464 where you will find a set of various symptoms which indicate failure of the machine to find its system folder. Each of the symptoms has a link to the appropriate corrective action.

Dual G5 hangs while booting from internal hard-disk

Hi,
When I switched my Dual G5 (2x2.5GHz around 15 months old, 1.5GB ram, 160GB hard disk, OS 10.4.6) on yesterday, it wouldn't boot from the internal hard disk. The spinning "wheel" (under the Apple logo) didn't show up and after a couple (5? 10?) of minutes the fans started making more noise than they ever did. I tried again with the same result.
It did boot from CD though and the disk was accessible. Disk Utility didn't report a problem and the hardware test neither. Subsequent rebooting from the internal hard disk failed again.
Then I reinstalled 10.4 (with archive & install), but with the same result. Then I got a Firewire drive from the computer support department, formatted it, installed 10.4 and copied (nearly) the entire internal hard disk's content to it. I was able to work normally from that disk.
Then I booted again from the 10.4 installation disk, formatted the internal drive, reinstalled 10.4 and then it did boot from the internal drive. I migrated all my files and now everything is working again (although a few things might have gone missing). And I lost nearly a day of work.
I conclude from this that it wasn't the disk, but that somehow an essential part of the boot software got damaged.
My question: how did this happen? What could have caused it? Is there someone with a similar experience (i.e., failure to boot from disk while the disk is still ok)? Is there any way to prevent it from happening again?

we have g5s the same as you. the few times we've ever had an issue with them refusing to boot up have been solved by running diskwarrior. it's an utter 'must have'.
it's a harsh fact that drives (and the operating system that sits on them) do fail from time to time. careful housekeeping (repairing permissions regularly, running disk utility repair and/or diskwarrior) will help to prevent any major problems.
if you have an issue that can't be fixed by doing these things (and we just had one with a file sharing problem) the best course of action is a full reinstall.
we keep a fw800 drive with the latest installers of every application we use handy in each room for this purpose. it's time consuming to stay on top of but worth it when it all goes pear-shaped.

Internal hard disk really slow to write new files

Hi
I've had some problems with my mac lately;
it was running really slowly so I ran tech tool deluxe and it detected a bad surface sector.
I wasn't sure how to fix this so I copied everything from my internal hard disk onto 2 external hard disks.
Then I deleted all documents, files and most apps from the internal hard drive and zeroed out all free space using disk utility. (Which took four days).
Finally I did a re-install of leopard and ran tech tool deluxe again, which came back with no problems.
However, now I'm trying to copy all the files back onto hard disk it's taking a very long time e.g. iTunes files totaling 31.41GB would take 14hours
Trying to move the same iTunes files to the other external hard disk takes 25 minutes.
Any help would be appreciated

Then I deleted all documents, files and most apps from the internal hard drive and zeroed out all free space using disk utility. (Which took four days).
It should not take four days to zero out free space. And it should not take 14 hours to write 30GB of data from a directly connected external drive. There is probably a problem with the part of the drive that was not deleted and zeroed; in the system installation. Or the problem could be in the disk directory structure.
The only way to fix it is to erase the entire drive. You should not need to zero out data, although doing so would do no harm and should take no longer than a few hours (depends on size of drive). Then reinstall a fresh copy of Mac OS X. After going through the updates and installing your apps, restore your personal data from those external drives.
If the drive is still acting slow, you may have a hardware problem with the drive.

Hi, I just put a new internal hard disk to my MacBook after formattimg it and I don't know how to install the OS X? Any help please

Hi, I just put a new internal hard disk to my MacBook after formattimg it and I don't know how to install the OS X? Any help please

Be sure you have prepared the new drive correctly:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.

Cannot Access USB Hard Disk

I have a USB hub connected to my airport with a printer and USB hard disk attached. I can see in manual setup in AirPort utility that both the printer and the hard disk are set up and connected. The printer prints wirelessly.
My problem is that I cannot find the hard disk on my computer in order to take and put in files. Where is the hard disk located???

In the Airport Utility /Disks/File Sharing make sure 'Enable file sharing' is checked. Select your choice for access (Secure Shared Disks).
Airport Disk Utility: I have enabled 'Automatically discover AirPort Disks' as well as 'Show Airport Disks in the menu bar'. My action for the Airport is 'Connect with Password'.
More often than not every disk I add to the hub (which is attached to the base station), shows up immediately. When it doesn't, I simply use the menu bar icon, click on the airport name and click 'OK' once the disk availability box appears. My oresent setup is to remember the password in my keychain.
Note: since updating the firmware as well as Airport application, I have had no issues with hard drive access or, in particular, printer access.
