OS X Disk Utility not recognizing Seagate 3TB drive in dock
Been scouring the webs and can't quite figure this one out.
I just purchased a Seagate 3TB drive intending on using it for Backup.
Ended up plugging it into a dock and couldn't get it to show up in Disk Utility..
Interesting enough, I plugged this into an HP laptop and it displays just fine.
Anyone know the solution?

I hooked my internal as an external up to my Mom's Macbook Pro and it recognized my HD. I'm thinking it is something internal with the hook-up, which is awesome, because maybe I can actually fix it!!!!  Any thoughts?

  • Copy of a CD (created by Disk Utility) not recognized by Windows or Linux

    I created a copy of AutoCAD 2005 (not pirating it... just wanted a backup copy of the install CD).
    I used Disk Utility (File > New > Disk Image From Folder) to successfully create a DMG file on my MacBook. I could mount the DMG and browse all the files on it.
    I then burned a CD (Disk Utility > select DMG > click burn), which mounts fine on OSX. However, my Windows and Linux boxes will not recognize it (while they recognize the original CD just fine).
    I tried again, this time setting the file format to DVD/CD master. It made a CDR file, which I burned to CD. Got the same result: Windows and Linux don't recognize it while OSX does.
    So instead I burned the files to a CD ala drag and drop using Finder. This time the CD was recognized by Windows and I used it to install AutoCAD.
    However, my understanding is that doing it this way won't work for a bootable CD, so I'd like to figure out why Disk Utility wasn't able to make an exact copy.
    Any thoughts? Problem with copy protection? Problem with the CD's file system?

    Yeah OS X's Disk Utility doesn't burn using the ISO 9660 file system while Finder does (I could swear I made a copy of an MS Office CD with Disk Utility, but maybe I'm remembering wrong). Anyway, Disco (a program I got in a MacHeist bundle) will make an exact copy of CDs. Anyone looking for a free solution, check out LiquidCD and burn, which may have the ability to copy Windows CDs (appears to be on their lists of features, but I haven't tried them myself).

  • 'No' symbol on start-up, disk utility not recognizing internal drive

    Need a little assistance.
    Two days ago I was using the Macbook and it froze. Restarted and I was hit with the international no symbol. I've also gotten the blinking file folder at times when I've tried the holding down of various buttons on start-up.
    I put a Hitachi 750 gb harddrive in last fall, it has been working fine up until now.
    I do not have the system disk for Snow Leopard on hand, so until I can get it from my Dad, I decided to check on the system disk I actually have from the laptop purchase in 2007.
    This allowed me to get to the start-up disk and disk utility area. I could not find my external harddrive in the list for a start-up, and it is the back-up using Time Machine. I also could not get the internal harddrive to be found in the utility so I could do a repair. It did seem to recognize that there is a drive, but not the actual named portion of it that contains the info.
    I removed the internal and put it in an external case: my netbook recognizes that there is hardware, but does not let me access it. I attribute this to the fact that the drive is formatted for Mac and the Windows machine can't recognize the data.
    My next step was to see if my old iMac would recognize the internal as an external, but since I don't know where the keyboard is and it is running an early version of OS X, figured it won't do me much good.
    What is my next step? Will the Snow Leopard disk make a difference? Or is the reaction with the older system disk going to carry on the same way with Snow Leopard?
    I was going to buy a Macbook Pro, but not for over another month, so I'm hoping I can figure something out with this and make it last a little longer.

    I hooked my internal as an external up to my Mom's Macbook Pro and it recognized my HD. I'm thinking it is something internal with the hook-up, which is awesome, because maybe I can actually fix it!!!!  Any thoughts?

  • Disk Utility not recognizing connected disks half the time

    About half the time i run Disk Utility all i get is the Disk Utility window that's blank on the left side where my connected drives should be and in the main area of the DU window is the message "Gathering disk information" will a spinning wheel type thing under it. The only way i can quit DU is by forcing a quit. I don't have any idea why this happens so much. I've run repair permissions and repair disk from the install disk. No problems detected.
    Any ideas?
    thx
    lenn

    disk utility can only repair directly attached drives. it can not work on network drives like Time Capsule. but you can try repairing the sparse bundle itself. drag it to disk utility's left pane, select it there and choose "repair disk".

  • Disk Utility not recognizing Time Capsule Disk?

    Hi I'm receiving the following error message from Time Machine:
    "The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."
    I am able to access the Time Capsule's hard drive via Finder, and can see the sparsebundles there, but when opening Disk Utility the Time Capsule does not appear on the left sidebar along with other hard drives (such as that of the iMac and an external USB drive).
    I've gone through restore and factory resets, this message continues to come up...any suggestions?
    thanks

  • Disk utility not recognizing HD

    Hi,
    I have a G4 PowerMac with two 80 GB hard drives. When I boot up the computer, it boots up from the primary drive and runs fine. At this time, both my primary and my secondary drives are accessible and visible.
    However, when I boot up the computer using either the Tiger or Leopard DVDs and then run Disk Utility, it only recognizes my secondary hard drive and not my main hard drive.
    Also, if I quit Disk Utility at this time and tell it to re-start, it asks me which drive to boot from and the only option is either the DVD or the secondary hard drive. It just doesn't even see my main hard drive. I have to eject the DVD and re-boot for it to boot from the primary drive again.
    Any advice?

    I can see and use the hard drive only when I boot from it. When I boot from it, it is on my desktop, in my System Profiler, and visible under Disk Utility.
    When I boot from DVD, the drive is not visible anywhere - not in System Profiler and not in Disk Utility.
    I booted the computer using the HD and did a "Verify Disk". It gave me several errors and one in red that told me I needed to do a disk repair. I did a disk repair by booting the computer into Safe Mode (which performs a disk repair automatically). Then I rebooted regularly (from the HD) and went into Disk Utility and did another "Verify Disk". This time it verified successfully. I also repaired permissions successfully.
    However...
    when I booted from DVD, the drive was again invisible.

  • Disk Utility Not Recognizing Hard Drive - PLEASE HELP!!

    So, I just bought this Power Mac G4 from a friend to run my Digidesign hardware. I turned it on this afternoon to install the Apple software for the wireless mighty mouse. When I turned the computer on, the second hard drive was not present in Finder, and I could not locate it in Disk Utility.
    I have two hard drives present in the computer ... the 120gb main hard drive and this 2nd internal 80gb hard drive. I'm not very "tech savvy" with the comptuer outside of running protools ...
    Does anyone know what the problem could be? Or is it likely that the hard drive just fried??
    Thanks,
    Justin

    When two hard drives are attached to the same data ribbon cable, connected to the same IDE controller, one drive must be configured as "master," and the other drive configured as "slave." This is accomplished by placing a plastic jumper (sometimes two jumpers) across a specific pair (or pairs) of pins on the back end of the drive. If the manufacturer didn't apply a label to the drive with jumper designations, the user manual or manufacturer's web site will have the info needed for that specific hard drive. The drive connected at the end of the ribbon cable should be configured as master, and the drive connected to the middle connector as slave. If the 80 GB drive isn't mounting, it's probably configured the same as the 120 GB, so check both drives.

  • Disk Utility not recognizing externals correctly

    I have two external hard drives that are connected through a USB 2.0 hub. One is called "Photo Store" and the other is called "Photo Store Backup". When I load them, they both show up on the desktop properly. However, when I load Disk Utility, things show differently. They show as separate physical drives, but with the same name and all the same information (UUID, etc.). At the same time, it still shows the drives on the desktop properly.
    What can I do to fix this?

    My fix was to just reformat one of the drives. That changed the UUID which was conflicting between the two drives.

  • Disk Utility Not Formatting External USB Drive

    Hello,
    I recently upgraded to Leopard.  Around this same time, my company purchased two, 1 Terabyte USB External drives for my coworker and I in the graphics/web development department.  They arrived this morning and we were very excited.
    My problem is that I cannot get Disk Utility to erase/format the new, external USB TB drive for use with my MBP.  Disk Utility fails almost immediately with the following message:
    "*Disk Erase Failed*
    Disk Erase failed with the error:
    File system formatter failed."
    The options I'm choosing for the Erase are:
    Volume Format: MAC OS EXTENDED  (i've even tried the 'journaled' version too)
    Name: TB
    As soon as I hit 'Erase' I get the error message I listed above.  The volume never mounts on my desktop and does not exist.  I can see the drive itself in the System Profiler, so my Mac sees it, it just can't format it!  I've also made sure all my permissions were repaired, so I'm just a little confused as to why this simple task keeps failing?
    Is there some additional, esoteric step that I'm missing?
    My coworker was able to get his disk to work because he did NOT have Time Machine turned on yet.  When he connected his new TB drive, Time Machine asked him to format/initialize the disk and he of course said "ok."  I had Time Machine set to use my OLD external USB drive and it's been working great. As of this writing, my coworker is a happy camper. I, however, am not.  I'm not blaming Time Machine, just noting the differences between my coworker's experience and my own. Since the volume is not currently mounted on my machine, I can't format my disk the same way as my coworker has done using Time Machine, since Time Machine doesn't see the volume.
    My fear is that the manufacturer (whom I've also contacted and am awaiting their response) will throw this back to a software problem....and the folks on the forum here will point their fingers and say 'hardware problem.'  Ah, the eternal struggle.....who to blame?
    Any help or additional troubleshooting tips are greatly appreciated.

    This is the best, and only, way to format an external hard drive, which is courtesy of Kappy.
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must 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. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    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 will take 30 minutes to an hour or more 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.

  • Finder and Disk Utility not "seeing" 3rd hard drive...

    I've rebooted multiple times and "command, option, p, r" ; tried putting my hard drive from slot 3 to slot 4 in mac pro, it is not being read.
    J

    What drive? make/model/size etc
    Normally an unformatted drive will cause a dialogue on startup (eject, ignore, initialize)
    Moving isn't going to help. 
    Look inside to see the drive will slide in and you don't have any issue.
    Then run Apple Hardware Test
    More likely if anything is drive is DOA; logicboard; 'foreign' format that DU can't mount.
    Putting in a FW case might be handy.

  • Disk Utility not finding Hard Drives after Updates

    Howdy;
    Updated my B&W G3 to 10.4.4 and itunes 6.0.2. After update and restart, ran Disk Utility (DU), which seem to just get into a loop "Gathering disk data". Force quit DU and tried running from Tiger DVD, but similar story.
    I have done a little research and there has been many problems with DU linked to itunes 6.0.2 update, but not quite the same (no B&W G3 w/10.4.4 and different DU hang point).
    I followed: http://discussions.apple.com/message.jspa?messageID=1505537#1505537
    and even tried moving iTunes to desktop; trashing several iTunes.pkg files; restarting, all to no avail.
    Any additional suggestions out there?

    I doubt that any jumpers are needed, since this is the only (master) drive in the system. WD's site has pretty good info on this. Verify for yourself however.
    Also, from their site:
    How to partition and format an internal slave drive or an external drive in a Mac OS X (all versions).
    Answer
    In Mac OS X, you can use the built in Disk Utility to partition and initialize the drive so it will appear on the desktop.
    1. Open the main drive (the drive that contains the operating system).
    2. Open the Applications folder.
    3. Open the Utilities folder.
    4. Select Disk Utility.
    5. The drives are displayed on the left side of the window. Click on the drive that you wish to partition (the top drive listing for the hard drive that you want to work with).
    6. Once the drive is selected click on Partition.
    7. Click on the Options button to select the partitioning scheme.
    8. Click on Apple Partitioning Scheme or Apple Partitioning Map and then click on the OK button.
    9. You will see several options for setting up the drive. Once you have selected the number of partitions, the format type you want, and a volume label, click the Partition button.
    10. Following the completion of this process, the drive will appear on the desktop.

  • "This disk is not recognized by this computer"

    I have a FireWire LaCie external disk, that suddenly stopped working.
    Did some copying of files and then I discovered some folder were missing.
    Then I restarted and got the message "This disk is not recognized by this computer. I did choose Igonre and when I run Disk Utilty I get this message:

    Volume check failed.
    Error: The underlying task reported failure on exit
    1 HFS volume checked

    What shall I do? I'm panicking, since there are life-important (almost) files on the disk.
    I have Data Rescue II - do I dare to run the program, or shall I take the disk to a company??

    Bought the Data Rescue II, have restored most of the files. I think so, at lest. Many orphans, but at least they do have their names intact, and I have a pretty good idea where to put them. I only hope that the PSD files are intact too, all my video assets are on Beta and can be re-captured if needed.
    Tanks for your tip!
    It's the SECOND failure today - first I replaced an existing folder with an empty one and copied another 40 GB of files to the disk. Not much to rescue there...
    And then this happens. Not having a good week so far.

    Another thought is to check System Preferences/CD's & DVD'S, and check your selection nuder "When you insert a blank CD" (or DVD).
    Running Disk Utility from the install disk, and repairing permissions is also another possible fix.

  • I've tried to conduct a secure erase with disk utility. I highlight the drive but erase options are not available.

    I tried to conduct a secure erase with disk utility. I highlight the drive but there's no place to click "erase."

    If you have an SSD, then the best thing you can do it enable System Preferences -> Security -> FileVault, so that any deleted files are just an encrypted jumble of bits to anyone that does not have the encryption key.
    And even if you do erase the SSD, it does not work the way you think, and retired SSD zones may have your data, and never see an erase.
    This is way keeping the SSD encrypted means retired zones are just encrypted jumble of bits.
    If you do NOT have an SSD, is it possible you are trying to erase your boot disk while you are actually using your boot disk?  Disk Utility will not allow you to do that either.
