Disk utility on remote drive

Hello,
I look around and found nothing on this forum. I would like to use Disk Utility to verify a remote USB Hard drive plugged to my Airport Extreme. When I open Disk Utility this drive does not appear in the choices. Is it possible to see it?
I have another USB drive directly plug to my Mac and I use it for time Machine, I was able to verify this disk without problem.
Thanks for any answer you may provide.
Thierry

Disk Utility will not work on a networked drive such as your situation. If you need to scan the drive with Disk Utility, then disconnect it from the AEBS and connect it directly to your computer.

  • After SN install can't launch Disk Utility from external drive

    I recently upgraded 10.5.9 to SN on my white Macbook. First I used Carbon Copy Cloner to clone the old drive onto the replacement drive in an external enclosure. Then I swapped drives so that the new drive is now the internal drive and the old drive is in the enclosure. I then upgraded the OS on the internal drive via SN installer on DVD.
    Now when I start from the external drive in OS X 10.5.9 and try to launch Disk Utility from this drive I get a weird error message that "Disk Utility can't be launched because it's incompatible with this architecture." The only things I can think of is that Snow Leopard installs something that globally effects all perhipherals (like new disk drivers?), or that there is something in the enclosure's USB bridge which is causing this, or that installing Snow Leopard breaks the PRAM for older versions of OS X. Tech support for the enclosure vendor tells me there is nothing in the enclosure's USB that would cause this. Any insights into what's happening appreciated.

    Thanks for response. Ah, that's it. I was trying to launch it from the applications folder I had dragged to the dock, which was done while running Snow Leopard. That's why (duh!) all the application icons were slashed out. : |

  • Disk utility/external hard drive failure

    I have a MacBook that I got about two years ago and a Western Digital portable external hard drive (WD Passport) that's almost as old. I keep almost all of my music files on my external hard drive and then play them through iTunes. About a month ago my external hard drive stopped working. I plug the hard drive into my computer and the blue light comes on. It even shines brighter for several seconds as (it appears) the hard drive attempts to mount. But every time I do this the blue light then becomes dimmer and the drive never mounts. When the hard drive is plugged in and I open up the Disk Utility application the drive shows up. When I try to manually mount the disk it tries and fails. When I click "Verify Disk" it tries and then an error message pops up saying "Phase 1-Read FAT, Unable to read FAT (Input/output error)". I've read that the PC disk utility application may be better at reading drives so, once I'm in a place where I have access to a PC, I'm going to give that a try. Does anyone have any other suggestions?

    I am assuming that you're using the Passport in the same USB port that you always have. I ask this because some people complain about USB devices working on one port but not the other, as they claim that one port may put out more voltage then the other. If this is happening in your case it would kinda make since as when you plug in the Passport all that is required is the logic board power then it will start to spin up the disk which will pull down the power and that may be why you're getting a dimmed light on the Passport.
    Just try the other USB port to verify, I know it sounds silly but it's worth a shot.

  • Disk utility states: This drive has hardware problem that can't be repaired, backup and replace disk.

    I think that is a wise choice!
    Good luck and btw I hope you have a good backup, if you do use Setup Assistant to restore so you can pick up from where you left off. You should use Pondini's Snow Leopard Setup Assistant tips it will show exactly what needs to be done. If the Apple people are going to install SL for you make sure you give them your backup so they can restore for you.

  • Disk Utility from external drive?

    Our mac mini has a corrupted disk and needs Disk Repair, but the DVD drive is also broken.  Can I boot from an external DVD drive?

    Have you tried booting to the recovery partition, by holding the command and r keys down while booting (or the alt/option key)? That should bring up a short menu, allowing you to run Disk Utility to do the repair.

  • Disk utility crash, external drive won't mount

    Hello,
    I was performing disk utility on my Toshiba 1T external drive. The disk needed to be repaired, and while it was in progress, I had a system crash. Now I cannot get the drive to mount, it's indicator light is flashing. I suspect the drive needs a data recovery professional now...but I'd like to know if there are any steps I can take with it.

    Turn it off and leave it that way.
    Professional data recovery is expensive (think thousands). You could try software, a Data Rescue is well regarded.

  • Disk Utility and Hard Drive replacement on MacBook.

    I am preparing to upgrade the hard drive on my MacBook and I was reading this document http://manuals.info.apple.com/en/MacBook13inch_HardDriveDIY.pdf and a the end after installing the hard drive and preparing to install Mac OS X the directions state the following: "Leave the Disk Utility application open, and restore the backed up files from the image you created before removing the hard drive.". I think that this would be a much quicker option then having to re install every application and copy over back up user data. My question is how do I create an image of the contents of the hard drive to use once I upgrade the drive?

    I'd just clone (make a complete bootable backup) the internal to a backup external drive, swap out the internal, then clone back. That way you wouldn't have to do any installations.
    To backup (clone) your main drive, you can use the donationware CarbonCopy Cloner @ http://www.bombich.com/software/ccc.html , or the shareware SuperDuper @ http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html , or the freeware IBackup @ http://www.grapefruit.ch/iBackup/index.html, or the Restore function of Disk Utility included in OS X.

  • Disk utility's encrypted drives and user permissions

    I've decided against using filevault based on some of the feedback and research I have conducted. I am still interested, however, in encryption of some documents. I have used the Disk Utility to create a 128 bit encrypted .dmg image. I mount it using my user account, but only as r-x. I see that root has write permission, and so I assume it is safe to write to these drives. What is the best way to make it so that my user account has rwx permissions? I could manually do a chmod each time I mount the drive, but that seems silly. Also I noticed that apple doesnt seem to mount drives using the same files as linux, so I'm a little confused. Could someone please provide some insight to this. Also, *put on tin foil hat* how secure is this? When I access the drive is it writing unencrypted data to the swap file? thanks,

    Hi, iMacGyver.
    A. You wrote: " I have used the Disk Utility to create a 128 bit encrypted .dmg image. I mount it using my user account, but only as r-x. I see that root has write permission, and so I assume it is safe to write to these drives."Were you logged in as root when you created the dmg? Or did you create a read-only image from a folder containing the documents?
    To create a disk image to which you can add/remove documents and on which you will have Read/Write permissions:
    1. Log in to your account.
    2. Launch Disk Utility.
    3. Select File > New > Blank Disk Image...
    4. In the New Blank Image window, type a name for the new disk image in the Save As field, then select a location for saving the disk image, the desired Size, Encryption (select AES-128 in the pop-up menu), and leave Format as "read/write disk image."
    5. Click Create.
    6. Provide a password for the disk image when prompted. If you want extra security, de-select the option to save the password in your keychain, but be sure to never forget the password if elect to not save it in your Keychain.
    You can then double-click the disk image you just created, type the password when prompted, the disk image will mount, and you can add files to it. Ejecting the disk image will unmount it and all the content you added will be encrypted.
    One can use Disk Utility > File > New > Disk Image from Folder... to create either a Read Only or Read/Write encrypted disk image of an existing folder of documents, but if you elect to make it Read/Write there isn't much spare capacity for adding documents as the size of the disk image is based on the size of the folder.
    Also, if your comfortable with Terminal, you can look into the hdiutil command for creating and managing disk images.
    For example, if in step 4 above you selected the format as "sparse disk image", you'd later need to use the hdiutil command to compact the sparse image to recover disk space from files deleted from the spares disk image. Spare disk images are always Read/Write and only occupy as much hard drive space as the data they contain, e.g. a 100 MB sparse disk image containing 30 MB of files only uses 30 MB of hard disk space: they grow as files are added. A conventional R/W disk image of 100 MB in size takes up 100 MB of hard drive space even if it is empty.
    However, when you delete files from a sparse disk image, the amount of hard disk space it occupies does not decrease until you compact it using the compact verb of hdiutil. Disk Utility does not expose all of hdiutil's functions.

    C. You wrote: " Also, *put on tin foil hat* how secure is this? When I access the drive is it writing unencrypted data to the swap file? thanks"To use encrypted swap files, select "Use secure virtual memory" in System Preferences > Security. Depending on the applications you use, there may be a slight performance reduction with encrypted swap.
    D. Your questions imply you're new to Mac. While you may be familiar with Linux, there are differences, especially in doing things through the GUI. If that's the case, my "Learning About Mac OS X" FAQ has a number of resources that you will find helpful including books, online training, and more.

  • Only Partitions Showing Up In Disk Utility, No USB Drive

    I recently reformatted a 1TB WD My Passport Ultra to the GUID partition table with three partitions (400-550-50) using the Mac OSX Extended Case-Sensitive Journaled Encrypted filesystem. Now in Disk Utility the actual disk is not showing up, instead it only shows the partitions as disks. Can I fix this without a reformat?
    Potential Causes:
    1.) The 50GB partition was turned into a Truecrypt Volume
    2.) Last night the drive was disconnected mid-TM backup
    Computer - Late 2013 Macbook Air 13" 256GB w/ 4GB RAM
    Hard Drive - WD My Passport Ultra
    OS - Mavericks (sans SMC-firmware update, incremental OS update)

  • Disk Utility formats Hard Drives as Logical Volume Group

    I just replaced a hard drive which had died in my Mac Pro which has OS X 10.9.5. To format the new 3TB hard drive I went to Disk Utility. I used "Erase" in its fastest form and the drive was formatted with the Type: Logical Volume Group.
    I remember this was a problem a few years ago when I first put hard drives in this computer. I think it was considered a bug in the Disk Utility in OS X 10.8 that it would automatically format drives greater than 2 TB as Logical Volume Group. The solution for me was to restart the computer with my OS X 10.6 disk and use the Disk Utility in that to reformat the drive. I never really understood why Logical Volume Group was a problem but I just obeyed what the wise ones of the Internet had to say.
    So, now I am wondering if I should reformat my new Hard Drive as GUID using my OS X 10.6 optical disk again? If it was a bug in the Disk Utility of OS X 10.8 then why is it not fixed in the Disk Utility of OS X 10.9? Is there an actual problem with having disks format formatted as Logical Volume Group? Is this now just Apple's way of doing things?
    Thank you.

    You could do your reformat using your 10.6 DVD. That's a decision that's up to you.
    Not every bug in a previous OS gets fixed in a new OS.
    I don't believe CoreStorage (Logical Volume Group) causes any sort of issues. Whenever one encrypts their Macintosh HD, the format is converted to CoreStorage. Fusion Drives are using CoreStorage and now Yosemite converts portables (laptops) to CoreStorage during the install process. As far as Yosemite is concerned, Apple seems to have gone the route of CoreStorage for portables. Even during the Setup on a portable, FileVault is offered with the default of YES being checked. So, if a customer isn't paying attention and continues with the install, they could encrypt their drive without knowing to uncheck the default checkbox.
    Thank you for your reply.
    I have decided to reformat my new hard drive using my 10.6 disk. I like being able to split it up into more than one volume if need be.
    I understand that not every bug in a previous OS gets fixed, but this strikes me as being really a very large bug, so I think it would be good if Apple addressed it.
    It is useful to know about Yosemite's behaviour. When I upgrade to Yosemite I will be a bit more prepared. In fact my MacBook Pro has FileVault on with Mavericks so Yosemite won't change anything there.

  • Disk Utility wont drag drives on Mac book Pro

    I am tring to back up may system drive, and i cant drag it to the source on disk utility, acctually i cant drag anything into it, while i have no problems on my dual g5, so i guess the problem is on the intel disk utility.
    any ideas?

    You need to drag the volume, not the "disk"
    On most Macs, this would be "Macintosh HD"

  • Disk Utility: No Mac Drive in Internal HDD. Can't format or erase.

    Hey guys, I just got my new mac mini and I installed a Samsung pro 840 SSD. The thing is I messed up. I turned my mac on and everything went fine, Disk Utility showed up telling me that the drive was "unreadable". I decided to turn the thing off and start Recovery so I could install Mountain Lion onto the SSD. When igot to Recovery, disk utility told me there was an error with the drives and it had to erase them, while it was working I got the The Spinning Rainbow Beach Ball of Death so I turned my mac off. Huge mistake it seems. Now when I want to install Mountain Lion there is no available disk to install it. I started Internet Recovery and accessed Disk Utility again and the Internal Drive actually appears but with nothing installed in it. The option to erase or format are not available. I did a disk verification and repair and everything was OK. I'm going crazy over this. Please help me guys!!! I'm leaving a picture so its clearer. THANK YOU!!

    Being a new Mac Mini the system is attempting to create a Fusion Drive setup out of your SSD. Do you have dual drives in the system, the built-in one in addition to the new one you installed?
    This is an issue with the new Mac Mini and iMac systems (see here: http://reviews.cnet.com/8301-13727_7-57584237-263/disk-utility-may-combine-custo m-drive-setups-on-some-macs/) as these systems ship with Fusion Drive setups and Disk Utility assumes this is the desired setup when you use it to "fix" the drives.
    You can see that when you select "Internal Drive" the type is "Logical Volume Group." Since this group is greater than the 840GB, my guess is this is the combined space from your SSD and the built-in one.
    To clear this issue, open the Terminal (from the Utilities menu in the OS X installer), and run the following command:
    diskutil cs list
    You will see a tree of information, with one grouping showing a UUID for the Logical Volume Group (the UUID will be a string of numbers and letters, separated by several dashes).
    With this UUID, run the following command to destroy the logical volume group (you can try copying and pasting the UUID, though I"m not sure if the services in the Recovery HD partition support copy and paste--otherwise just type it in manually):
    diskutil cs delete UUID
    When finished, follow the instructions in the artifcle I linked to above to install OS X to an external drive (if available) and use Disk Utility there to fix and manage the drives, as opposed to the version in the Recovery HD partition.

  • My external drives no longer appear in Finder, BUT they do appear in Disk Utility (and network drives appear also)

    Hi folks, I hope someone can assist.  I have a Mac Mini 2011 running 10.8.5.  All has been well. Suddenly, when I plugged in an external flash drive (USB), nothing showed up in Finder.  Things I have done:
    Confirmed SideBar and other Finder preferences are set to show/reveal external, network, and internal HDs
    Tried multiple flash drives and hard drives, using drives formated in GUID/OSXExtended as well as FAT and NTSF. None show up.
    Confirmed that the Hidden flag in terminal is not set.
    Note:  I can see the drives in Disk Utility, but the partitions/volumes are gray and will not be mounted.
    Note: Network drives and internal drives appear and work as expected
    Note: My network Time Machine also appears and performs as expected.
    The only suspect I can think of is a small, free app I installed this morning called Caffein (which manages the sleep mode).
    Also, I loged out and switched to another user account on the same machine (that I use solely for the purpose of troubleshooting), and it was similarly affected.
    Thanks in advance!

  • Using Disk Utility to partition drive

    After downloading a system update yesterday my mac mini hard drive is no longer bootable. The recovery HD is unbootable, too.
    When I boot up using the install CD I can run Disk Utility and see that there are no problems reported with the hard drive, but I cannot repair permissions (No valid packages).
    If I restore the operating system from the CD my only option is to erase the hard drive.
    But what if ...
    I create a new partition using Disk Utility?
    There's loads of free space on the drive, but if I attempt to create a new partition will I wipe out existing data?
    If I succeed in creating a new partition would I be able to restore the operating system there without erasing the hard drive?
    Would it be possible then in some way to restore my user account data?
    I'm just trying to avoid the hassle of re-installing my applications and recovering my data files from backup. It seems like the data is still all there on the hard drive except that something went wrong during the system update that renders the disk unusable.
    Any help appreciated.
