'Disk Utility' showing 2 HDs...?

When I click on Disk Utility it shows 2 Hard Drive icons; one saying Macintosh HD, the other 111.8 GB ST9120821A...also they have different text descriptions at the bottom of the Disk Utility window....?
Should both of these items be listed ?

Hi Robert,
Steve is basically correct. The upper icon represents the entire disk and the lower, indented icon is the "volume". So Macintosh HD is your "volume".
Note that 149.1 GB LaCie GroupSA is a "hard disk drive" and there are 2 volumes on this disk because it is "partitioned".
Normally when running "Verify" or "Repair Disk" or "Repair Permissions" you would want to choose the volume.
Refer to what Disk Utility tells you before you choose, "Select a disk, volume or image."
Images like "zlock.dmg appear below the divider:
Hope this helps.

  • I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

    Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.

    Have you tried to repair the disk yet

  • Trying to install 10.9 yields "damaged HD message," but disk utility shows everything is fine.

    Running mid-2010 MacBook Pro 13'' with OSX 10.7.5.
    So, like many who have tried to install the new update, mine says it cannot be installed due to a damaged Macintosh HD. Attempting to fix it through the Disk Utility available during the install allows me to Verify Disk. I get an error that it needs to be repaired, but the repair option is greyed out. Booting it into Recovery and using Disk Utility again shows a damaged disk, but this time I can repair it. It repairs and everything reads as fine; even verifying the disk again shows that the system is fine. This is where it gets screwy.
    Upon reboot, the Mavericks install wizard once more gives me the damaged HD message. It once more shows a damaged disk through the Maverick's screen Disk Utility. Booting it into recovery shows the damage again, is fixable again. Rinse, repeat.
    Booting into Safe Mode and running Disk Utility shows an undamaged Mac HD. It also allows me to access everything as normal (which is how I am on here now), albeit much more slowly. Additionally, my Boot Camp partition works just fine.
    I wouldn't mind abandoning the install, but the Mavericks install will not allow me to boot into my Mac HD because of some error. I also cannot avoid restarting into the Mavericks install wizard unless using Safe Mode. I attempted to delete the downloaded Mavericks "application" in the launch pad, but this does not affect my normal boot, and it appears again the next time I boot into Safe Mode.
    I don't know what's wrong with this, but I don't thing it's a hardware issue, because this only affects Mavericks. Can anyone tell me how to either 1) install Mavericks, or 2) banish this **** from whence it came so I can have my computer back? I've been trying to fix this for at least 9 hours, I'm starting to feel rather infuriated.
    The only option that I can think of at this point is to reformat and do a clean install of 10.9. Alternatively, maybe just keep 10.9 off my system because it seems to be a POS.

  • Disk Utility shows Disk1, not mounted, and no further information???

    Disk Utility shows my correct disk partitions in the top section (my hard disk with two partitions and my superdrive). In the lower section, however, there is a "disk1" which shows no information. Under that is another "disk1" which shows only 'Not mounted' for 'Mount Point:' and '0 Bytes' for 'Capacity'. All other lines only show dashes.
    I looked at my /Volumes folder in Terminal. It shows four entries:
    x MPBWinXP - which is my boot camp partition
    x MacBook Pro HD - which is my OS X partition
    x MacBackups-1 - which is an external drive on my network (for my Time Machine backups)
    x administrator's Public Folder - hunh?
    So, this "disk1" in my Disk Utility must represent one of the last two, I'm thinking. And, I'm thinking the last one isn't supposed to be there - or is it there because I shared it at some point, maybe?
    Any thoughts on this and what I might do to get rid of the "disk1" from my Disk Utility display?

    I never received a reply to this, so I'm marking it as 'answered' just to close it out.

  • Disk Utility Shows Incorrect Free Space

    I've had this problem for a while now, and I've been unable to figure out why. I can't even remember when it started, but it has become quite a nuisance.
    The Finder window shows that I have 302GB of harddrive space remaining, out of 500GB. The Activity Monitor and Disk Utility show I have 240GB space remaining, and my System Profiler shows I have 239GB remaining. I just deleted a bunch of old TV shows off of iTunes (about 40GB worth) to open up some space, but only the Finder changed (up to 302GB from 260GB) but the Activity Monitor, Disk Utility, and System Profiler haven't changed.
    Now, I'll assume the Finder is showing the correct amount of space, but I'm wondering why the other utilites are showing the incorrent amount of space. I have a feeling maybe something was screwed up when I created a 50GB Windows 7 partition through Boot Camp a couple months ago.
    I've attempted to Repair Disk through the Disk Utility and it says everything looks fine. Any solutions to this minor inconvenience? Or at least an answer as to why this is happening?

    The available disk space reported in finder is totally wrong.
    Even if it accounts for the local snapshots. In my macbook air it shows 120 Available in finder which is just 1GB less than my SSD capacity.

  • Disk utility showing recover partition but not main partition

    I have a Macbook Pro A1278 that has been dropped.  I pulled the hard drive and ran seatools on it to verify it has no physical defects.  The disk utility shows the recovery partition but not the main partition.  It infrequently will boot to the users partition.  I usually get the flashing folder with a question mark in it.  What is the next step to try to backup the data on the drive and reinstall OS X.

    It would be really helpful if you would answer the question as I asked it
    Last time
    Did you do this from the Recovery mode (either Recovery mode, internet or local)
    Yes or No

  • My MacBook Pro 13 inch makes a clicking noise from the hard drive and can not start up in safe mode and normal. I then ran disk utility in recovery mode and disk utility shows no problems with the hard drive. What is the problem?

    Please help me, I have a mid 2010 Mac book pro with a toshiba mk3266gsxf harddrive. It started making a clicking noise and then my computer crashed. I proceeded to boot in safe mode, but it doesn't work. When I ran disk utility in recovery mode, it showed no problem with my disk. Does any one know what the problem is?

    Sounds like a mechanical problem with the drive and it ruined the sectors where the Macintosh HD partition (and OS X, and files and programs) reside, but not your Recovery HD partition.
    If you held command option r while booting, that's Internet Recovery and it's loaded via the Internet, not via the Recovery HD partition on the boot drive, so that could mean the drive is dead mechanically or there is another issue.
    In either case the drive will likely have to be replaced, it's a matter of what occured to where and the drive state if you can recover data or not. If you made recent backups then your fine.
    My computer is not working, is my personal data lost?

  • My HD in disk utility shows free space of 200GB and is greyed out. I am unable to do anything with this free space.

    I dual booted my mac until recently with refind. It all worked fine until recently when i tried to remove the ubuntu partion as I did not need it any more.
    Unfortunately, I am now not able to do anything to the 200GB of free space that shows in disk utility. Please help.
    I use Yosemite now.

    worked it out. thanks:)

  • Disk Utility froze, HDs no longer functioning

    I have a Western Digital MyBook 1TB external HD that consists of two 500GB drives in its enclosure. I had bought an OWC 1TB external of the same configuration, and a few days ago disk utility froze while verifying the disks. They were both set to RAID1, mirrored. Suddenly, their partitions weren't working properly and I was getting error messages telling me to backup my data. While I finally reformatted the OWC drive's partitions and setup my RAID1, the WD drive is only showing one of its two 500gb drives. What happened? How can I restore my WD Raid? Can I rely on these disks?

    Don't know, but pointed you there because these forums are for Apple products, and disdain using WD products because they don't support booting Macs, even though they claim some should. Additionally, their crapola SmartWare is problematic.

  • Can't find .dmg file Disk Utility shows is there

    I've been trying to clean up/gain space on my G4-12" PowerBook. In Disk Utility it shows a .dmg file that when mounted is an audio CD I received from a friend a couple of years ago. I imported the songs from it at the time, ejected, and that was that. Now I see in Disk Utility that this dmg holds ±500mb of space, but I can't find it to delete it. This is quite strange and never happened before. Find, Spotlight, EasyFind (including looking for invisibles), etc. cannot locate it. In Disk utility it shows the path as /Volumes/<name>, implying it is mounted. Upon clicking 'Open' it mounts the <AudioCD> which then shows up in the left side of my Finder windows. I can open this volume, click on a song and it plays, so it is clear that it does exist and not just an artifact. I can eject the AudioCD and it disappears. But I can't get to the .dmg file to make it go away.
    Any ideas on this are greatly appreciated as I've run out of paths to try....but I've not dipped into Terminal so would greatly prefer an alternative if it exists. Thanks in advance!

    Have you done a Find/Search using just dmg, rather than a search for the file name?

  • RAID Admin and Disk Utility show different sizes

    Hello all,
    I have tried searching through these forums for a resolution to this, but did not really find one. Here is my situation:
    I have an XServe Dual G4 in a branch office. It has attached to it an XServe RAID. Last week, when I was down working in the office I added a new drive to the RAID. The lower channel on the RAID had 4 172GB drives in it, and I added a 5th and and told RAID admin to resize the RAID.
    The next day, the RAID was finished resizing. RAID admin was reporting that the array was now 690GB. However, after rebooting the server and RAID multiple times, Disk Utility in OS X is still showing that the Volume on the RAID is only 517GB.
    So, I have a couple of questions:
    1. How is it possible that by adding a 172GB drive to a RAID 5 array that was about 520GB I ended up with an array that is 690 GB? That would imply that there is no parity (since 690 - 520 = 170 and the drive I added in was 172GB).
    2. How do I get the server to see the additional space? The server is at the newest version of the OS and the RAID it as the newest version of the firmware.
    Please help.
    Mac OS X (10.4.8)

    I've run into the same issue with a newer PPC XServe. However, after I tried to reformat, I still only show up with the orginal size, and not the new size, even after I restarted the server and XRAID.
    Did you have any success with your reformat?

  • Disk Utility shows 0,00 Bytes (0 Bytes) for 2.73 TB Array

    I have an Xserve Raid connected to an Xserve G4 dual 1GHz 10.2.8 Server. I have had a 700 Meg Raid 5 volume for several years with no problems. I just purchased 7 500 GB ADMs to add to the second controller. I first upgraded the firmware to "firmware-1.5-1.50.xfb". I have tried recreating the Array 3 times with no success. Yes I have restarted the server many times and it shows the same thing every time. I would like to avoid upgrading the system software if possible. Here is a link to the Disk Utility screen shot.

    Thanks for the help.
    Xserve Raid   Mac OS X (10.2.x)  

    IIRC your problem is 10.2.8. It can't deal with a volume of that size.
    You should find that if you can format it (maybe on another machine) it will work, but you will get strange readings on volume sizes, space available, etc.
    For example, I have a 2.2TB volume shared by NFS that reports as 187GB on a 10.2.8 system, with 600GB free - go figure.
    Yet the same volume reports correctly on every other system.
    I'm afraid you're going to have to upgrade the OS on the system to get this to work properly, or reduce the volume size so that it's less than 2TB.

  • Hard drive not identified during Installation. Disk Utility showing nothing in left side bar

    Some day before my Macbook pro shown the flashing question mark. I have tried to install thr OS Snow leopard using disc.
    When I started to install the OS, my start up disc ( Hard drive) is not showing for installation.
    I have gone through the Disk Utility to repair it, but in that  Hard drive is not showing in left side bar.
    Kindly suggest how can I recover my Hard drive to install the OS?

    That suggests that the drive is dead; if so, it needs to be replaced, and any data on it can only be recovered by a professional service, which can charge hundreds or thousands of dollars.

  • Disk Util shows "decrptedFile.dmg" and below Flash Player - Is this a virus?

    While doing some routine maintenance with Disk Utility I see a disk image showing but it is hidden. I have nothing  connected by usb except an external HD which is listed separately.
    I am worried about this because it shows up as a disk image but I cannot see it.
    The string is:
    /ROB'S /private/var/folders/00/28smjdm92zs__qh85x2sc2gc0000gp/T/decryptedFile.dmg
    I used REVEALER to make the files visible
    I find a lot of files in there but I have no flash drive connected.
    Is this some kind of hidden virus?
    Should I remove these files?

    OK. Got it.
    Thanks for the help and the quick reply!
    I booted up from an external HD and checked later and it was gone.
    I wouldn't delete it without being sure of what I was doing.
    I very much appreciate the information and help!
    THANKS!
