MacBook Pro :: Disk Utility Does Not Detect Hard Drive

Aug 2, 2010

Just installed a new HDD into a macbook pro that was dropped. Seems fine, loads the disk and then says it can install the OS, i load up disk utility and theres no hard drive int he list just the optical drive and the DVD, its not the disk that came with the mac itself its either my proper retail one or the one that came with my personal older macbook which might be the issue. Ive taken apart and reconnected the HDD and all seems fine internally. Are there any issues that cause this except not using a full retail disk which im going to try later on, just wanted to rule everything else out.

OS X V10.7 Lion :: Disk Utility Can't Repair Disk (1 Partition) On External Hard Drive

Apr 24, 2012

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper! 

Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'.  And it needs to be reformatted.  It's become a read only disk.  When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question.  I also noticed that there are a lot of files with "date created" being the same date in 1969!  These files may be letters I've written or photo's I added to that partition within the last few years. 

I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure.  Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive?  And how do I get the read-only files back to their original state.

MacBook Pro :: External Hard Drive - Disk Utility Can't Repair Disk

Jun 27, 2014

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:

Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.

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. 

Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive? 

I have a Macbook PRO late 2011 running OS X Mavericks.

OS X :: Disk Utility Screwed Up External USB Hard Disk

Aug 6, 2010

I have an external 500GB Freecom USB HDD with two Data partitions on it (FAT32 and NTFS). With a Windows tool, I made the two partitions smaller in order to free up some space (ca. 200GB) for an additional Mac OS Extended (Journaled) partition. This partition I wanted to create with the Mac OSX 10.6.4 Disk Utility. When I pluged in my USB HDD in my new iMac it mounted the two partitions, NTFS and EXT32 and the Disk Utility tool also showed the free (unpartitioned, almost 200GB) space on the HDD. Then, I chose to create a new Mac OS Extended (Journaled) partition and let the tool do it. ...which I probably shouldn't have done. Disk utility stopped and showed an error message saying that it cannot read the partitions anymore and that it needs to be closed. No partitions can be mounted anymore since then on this HDD. Here is the logfile entry of Disk Utility (unfortunately, it's in German):............

OS X :: Disk Utility Cannot See Internal Hard Disc

Jun 5, 2009

I have had a problem for about a month whereby my MBP won't shut down, it just hangs after it has cleared the desktop and only the wallpaper is displayed. Now disk utility won't see the disk at all, and Software Update also does not find any updates. It checks for new software for ever. My mac starts up fine, and I can use it as normal.

OS X :: Hard Drive Backup - Do Not Have Disk Utility

Jan 4, 2010

I am going away traveling and need to back up all my stuff off of my mac for the first time.. (pics, music etc the usual). I brought a WD Elements 500GB External Hard Drive and when I plug it into my mac book (OSx) it appears in finder, and the desktop but I can't drag and drop nothing into it. Apparently I have to format it! So have researched about formatting it, but I don't have "Disk Utility" in my utilities? My Mac was given to me from a friend second hand so i don't have the disks etc to get it. Any other way of formatting my Hard drive or a link to download disk utilities or any alternatives!

MacBook Pro :: Disk Utility Can't Fix Hard Drive?

Jan 19, 2010

the past couple of days my new macbook Pro (only had it a couple of months) has been really slow to boot, with a grey progress bar that I have never seen before. I googled it, and you all know what i found.

So I ran the disk utility, and selected analyze or whatever the button is, and it said I should load it from the INstall DVD, as the disk needs repairing.

Guess what. The disk cannot be repaired.

An error message about expecting 31 files but only finding 30?
It recommends erasing the disk and reinstalling from scratch.

Now, as far as I can see, apart form the slow boot times, everything else still works. Does this mean that it is just a ticking time-bomb that will break any time, or is just a couple of corrupt files that don't matter?

This is really annoying, I love my Mac, but having to reinstall so soon after purchase?

Apologies if there any other posts on here already, it is late, I am stressed, and would like a nice person to help me out.

OS X :: External Hard Drives And Disk Utility

May 25, 2010

My external hard drive has been corrupted and the error message is telling me to reformat it. However, through all the research I have done to find out how, everything I've found has told me to use Disk Utility to just erase everything on the disk to do this. When I try to do this, it tells me that I can't erase anything because the disk cannot be unnmounted. What should I do?

OS X :: How To Merge The Disk On The Apple Support Section Under Troubleshooting Articles For Disk Utility

Oct 7, 2010

After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.

When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?

Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.

MacBook Pro :: Folder With Question Mark At Startup - Disk 0 Showing In Disk Utility

Jun 24, 2014

I get this question mark along with a folder when starting up. I tried holding down the option key when turning on the power and then I get an internet recovery along with a globe. I click on the arrow below it and it takes maybe 15 minutes to start up. Then i get this disk utilities screen. I'm now unable to do anything. When going into disk utility, disk 0 shows with Mac OS X base system underneath it. All the clickable buttons are faded out. Is there something wrong with the hardrive? and where could i get this fixed? There isn't a warranty on it.

Windows On Mac :: Partition Error - Back Up Disk And Use Disk Utility To Format

Oct 9, 2010

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.

I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

OS X Mavericks :: MacBook Pro Only Turns On In Recovery - Disk Utility Can't Repair Disk

Sep 12, 2014

Macbook Pro running on OSX Mavericks is having problems. 

Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do. 

Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair? 

Info:
MacBook Pro, OS X Mavericks (10.9.4)

Windows On Mac :: Creating Window 7 Boot Disk W/Disk Utility

May 26, 2009

I'm currently in the process of trying to install Win7 on my Macbook Pro (purchased July '07) using an ISO burned to a DVD with Disk Utility. Unfortunately, the DVD isn't bootable, and while the symptoms match what's in this blog post, the author's solution involved using a Windows-only program.

I'd like to know if it's possible to re-burn the ISO without the version number in the filenames as in the original solution, but with Disk Utility or something else that a Mac can use.
