OS X :: Disk Utility, Finder, Or Terminal Is Reporting Wrong Volume Size?
Aug 26, 2009
I partitioned my disk using Terminal's diskutil. I decided i didnt need the partition anymore, so i deleted it (using Disk Utility.app) and added the free space to my mac partition. Basically, Finder and Terminal dont show the free space added back, and Disk Utility shows the space added back to the disk. I tried restarting, repairing disk (which coincidentally had an unrelated problem), repairing permissions, but the problem is still happening
I'm new to mac, have been using mine for only three months now, but couldn't help noticing a strange thing. When I go to Disk Utility or cmd+i on a selected partition, the size reported by OSX is incorrect. E.g. I have a 250GB disk, so I'm used to seeing 232GB as usable disk space, which is a totally normal thing. However, OSX tells me that my disk is actually 250GB. More advanced partition utilities (currently I'm using iPartition but suggestions are welcome) report the disk size correctly. So I began to doubt whether folder sizes are reported correctly or "scaled up" to match the size of the disk?
E.g. if I was an ignorant consumer and tried to put 250GB worth of data on the disk, it wouldn't fit as there is not enough physical capacity to accommodate it, is that right?
Is it the normal behaviour or I screwed something up in the system?
My MBP has been reporting issues over the last few days and recommending that I verify the disk. Whenever I do this, it says that it finds errors and I should reboot with comamnd-r pressed and choose disk utility. Which I do. However when I try to verify the disk or repair the disk in this mode, it never finds any issues? Logging back in and running disk utility will again report issues and recommend repairing What should I do?
I often add very large files to my system before compressing them, sending them to clients, and then deleting them. This process leaves me constantly thinking about how much disk space I have free. Disk Utility, and an Apple approved app called DaisyDisk (space visualization) typically help me accompish this. Sadly, as of this week I seem to have a problem. When I went and looked the other day Disk U was telling me that 250gb of my 320gb drive is in use. This seemed high to me, but to be safe I thought I'd delete some files I didn't need. After deleting a bunch of videos, and a backup of my Main Identity (19gb) from my system, I'd assumed I had freed up about 24gb, but when I went back into Disk U it was still showing the same 250gb in use. Yes I rebooted my system, and made sure the trash was empty.
As I investigated further I did a get info on all 6 folders on the MacHD and they added up to about 170gb. That seemed more realistic, so I did a get info on my MacHD and again it showed the same thing 170 in use and 148.something available. Note: I have no partitions on this drive. But yet, still when I go to Disk U it seemed to be stuck at only 64gb free. Today when I went and looked again I am still seeing the same amount in use and free on the MacHD get info, but on Disk U now I am seeing 108 free and 211 in use. Why the difference? I would think Get Info was pulling from the same place as the mac disk utility.
The last couple of days safari has been crashing pretty frequently for me. I've been using chrome no problem, but i do prefer safari, so I just googled it and got pointed to Repair Permissions in Disk Utility.
So I just opened Disk Utility, which I'm fairly sure I've never used before, and it's saying, under my HD "this drive has reported a fatal hardware error to Disk Utility. If the drive has not failed completely, back up as much data as you can and then replace it with a working drive."
It's saying it for both "FUJITSU MHZ2250BH FFS G1 Media" (I'm not even sure what that is) and "Macintosh HD".
There's nothing wrong with my computer? I've googled around and apparently this means my machines about to die?
I have my imac apart right now and replaced the internal HD as it was not working. I assume the problem is the new one is not formatted with OSX, so from the INSTALL CD I opened the disk utility and see only one drive called "MEDIA".? Or is that just part of the install dvd that looks like a HD? In the system it shows as not formatted, 0 bytes. When selected in Partition it says :
"This voume is the startup volume and cannot be erased. Size 7.1 GB The disk is not writable and cannot be partitioned"
So i guess thats not my new HD I am seeing? Other than that there is only the two OSX install CD icons.
I have 43GB available on a 120GB drive on my MacBook base model and I'm trying to partition via BootCamp.I'm trying to allocate 32GB to the Windows partition but I keep getting the following error message: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've backed up my disk and launched disk utility, and try to follow above directions here but the Mac OS Extended (Journaled) area is grayed out and when I click apply after highlighting the MacBook are (in blue), it errors out and says the disk is out of space.
My new 2010 hexacore Mac will have 24G memory, an OWC Extreme Pro 120G SSD (positioned in the lower optical bay) and four 2TB WD RE4 drives. I'll use my old Synology 209 NAS (two 1TB WD Green Raid 1 drives) for TM backups over 1000Mbps Ethernet. Yes, I'll need to upgrade to a larger NAS very soon. This will be my first Mac Pro (have MBPs and iMac) and will be used for web design and development (mostly Adobe CS5 products).
The SSD will be used for boot and application files. I plan to use Disk Utility to create a 1+0 Raid array for data files. For a Scratch disk, should I: 1) create a partition on the 1+0 Raid Array for Scratch 2) partition a chunk of the SSD for Scratch 3) attach a spare external 2.5" WD drive via Firewire 800 for Scratch
Based on my reading, it seems that option 1 makes the most sense but I'm not entirely sure if you can partition a 1+0 array with Disk Utility. I'm pretty sure option 3 is quite silly but wanted to toss out the idea. Lastly, are there any generic recommendations on scratch volume sizing?
Updating my hard drive to SSD. The first line is right on it's place: it tells the name for my SSD (which is: 1Tb Samsung EVO) On the picture below is shown the second line that is missing when the ssd is installed.Does this mean that MAC can't recognise the drive?Does it work properly?
I have to do a back up (I'm cutting in Avid) on this FAT32 volume (for interoperability it is formatted this way), but I can't mount it via the Disk Utility or the 'mount' command in Terminal (it doesn't list the device, despite seeing it in Disk Utility - the volume is greyed out).The drive is connected via Firewire 400 and 800, USB is not available (to few slots).
On one of our MacBook Pros (Late-2011), running the latest OS X 10.7.3, Disk Utility says the volume needs to be repaired. When I use Disk Utility from the Recovery HD, it says the volume appears to be OK. I verified by using fsck in single-user mode, and it found no problems either. Which do I believe? Is this a sign of a soon-to-fail hard drive?
I reinstalled Snow Leopard on a new volume, transferred stuff I wanted from the old volume to the new volume, and deleted the old one. In disk utility, I have not been able to stretch the volume to fit where the old one was. I can't change the volume scheme. Has anyone got a method to let me use my full 160GB hard drive rather than half of it? Or maybe software that can alter it.
I use Disk Utility (stand alone, on a USB key) to make backups of my system disk to an external disk and then transfer it from my home system to a MacBook and vice-versa when I need to travel.
Recently, I upgraded from 10.9.2 to 10.9.3 and, not long later, to 10.9.4. In the same period, I also had an increase (not a very big one, just a few GB, less than 15) in the occupied space of that system disk. The current amount of data on it is 164.64 GB.
I'm not sure if my problem comes from the sub-version upgrade, from the increase in data size, from both, or from something else. The home computer is an iMac with a 318.88 GB internal disk. The MacBook has a 500 GB internal disk. The partitions used on the external disk to make bootable backups are 400 GB big.
I can backup both internal disks to the external partitions (and boot on the resulting external disk when I check that it is usable). I can also copy the external backups to the MacBook system disk and boot on the result without problem.
But, recently, Disk Utility has started to refuse copying the content of the external backup partitions to the internal disk of the home system. It says there is insufficient space on the target volume. If the error message is correct, it means that I cannot backup 164.64 GB of data on a 318.88 GB volume!
For the record, the external backup partitions are OK when verified with SOS.
I have a 3 TB disk that I used for video files that I now want to use for backup. So I wanted to erase and partition the drive to wipe it clean. So after going into Disk Utility and "trying" to erase and partition the drive, it now only shows the drive and no volumes.I cannot create or partition volumes. I tried verifying and repairing the disc but that didn't do anything. The only buttons available are Verify, Info and Burn. What do I do to use the drive again?
I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of action
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

I forgot the name of a small app that allows to browse a disk and calculate folder sizes in order to clean a disk. I think the icon was a disk with a broom over it.
Trying to resize and existing volume using disk utility on Leopard. Have a 1TB internal Drive with 1 Partition (extended Journal), not a boot drive this is just for data, now want to add another partition (2 Volumes), in effect shrinking the size of the original so I have 2 equal sizes.
So Far I have used 450GB, so there should be enough room to do this right? Although when I go through the process, I get the message 'not enough space on drive'.
I recently upgraded my Macbook Pro to Snow leopard. About 4 days later, my Mac crashed. When I tried to restart, it came up with the grey screen with apple logo and spinning disc. I have tried all of the resets. I then decided to try and re-boot from the SL install disk. When it asked me to choose a destination volume, however, there was none available. I tried disk utility, but there was no disk available there either. I then went back and tried to use the original install disc that came with the Mac...same results. It appears that my internal hard disk has disappeared. I wonder if i am going to have to replace the hard drive?

I've run the disk utility verify disk several times and come up with an error (post title) indicating I have a corrupt HD and need to repair. I've rebooted with command R and run disk utility to repair the disk and it says everything is fine. Reboot to normal mode and verify continues to show the error.
Other info says the file system exit code is 8.

I bought a new 2TB Time Capsule, and had problems completing the initial backup. I finally sourced the problem to files that were buried deep in a stack of folders, which seemed to make the file name/path too long. Anyway before I realized that I tried to reformat the Time Machine, and this seemed to work ok. However Airport Utility is now reporting the Time Capsule Disk Size as being 1.8TB, rather than 2TB.
I think before I reformatted the disk it showed as being 2TB in this menu, but I cannot be sure. I am worried that I have somehow formatted it wrong and lost some data space? If I go into Disk Utility, it does say there that the Data partition is 2TB, so it seems strange that Airport Utility shows it at 1.8TB. Can someone else who has the 2TB Time Capsule let me know whether in Airport Utility it shows as being 2TB or 1.8TB?
I want to reinstall OSX but finder does not work and disk utiliy does not work and the computer does not see the dvd drive, when I boot and hold c it does not see the dvd and won't boot from it, is there any other way to do an install., it's the new imac 27" flat screen with core i5, 4GB ram, boot ROM version IM111.034.B00, OSX 10.6.3.
I just reinstalled Lion from a fresh harddrive. I did not use the migration asistance to pull files over to the new drive, I selested files and dragged them over, So not to fill the drive with things I dont need....
So I "Get info" on the main harddrive it shows Which is crazy! Then I use Disk Invintory and it shows:
and Disk Untility shows:
Why the difference? Simple question and How do I free up space? I'm also trying to back up using time capsule*

Having trouble with my backup drive. It's a 1TB WD My Passport Ultra.
The drive mounts in Finder, but is extremely slow. In Disk Utility, the drive shows the correct disk space usage and number of files; but in Finder it only shows the folders/files at the root level of the drive, and each has a size of zero bytes with no items:
What is happening? How can I access the data (it's obviously still there if DU shows the files) and (possibly) fix this?

I have used this drive for a little while now. It now won't be read by a my Mac Pro or iMac. I'm about ready to take the drive apart. I have tried all USB ports and different power sources. The blue light comes on the drive, the drive spins, but the computer won't read the drive...

I have a JVC Everio HD camcorder and am having some trouble importing the video. This morning, the camcorder was recognized by Finder and I could enter and view the files. However, the files are in .MOD/MP4 format so they would not import directly into iMovie.
This afternoon, I found a tutorial on how to convert the files so plugged my camcorder in again, only to find that Finder is no longer acknowledging it. It is recognized in iPhoto and Disk Utility.
I purchased a black MacBook (10.4.11) last may and it's my first Mac. Thus far, I have only had one problem and that is that my I can't see my Motorola Z6m in finder or disk utility (but it is in system profiler). I also do not see it in Terminal under /Volumes. Inside the phone is a 2GB Verbatim microSD card that works fine in my card reader on the same machine. On a side note, bluetooth works fine.
The phone works as expected in the PCs I've tried it in, including a parallels vm running XP on the MacBook (I don't have access to any other Macs) which led me to believe it was a formatting issue, but then the card shouldn't work in the card reader either and it should still show up in disk utitlity. Am I not correct?
I have tried rebooting, unplugging/replugging the device, removing the battery, and reinstalling OS X (I wanted to do it to get rid of Unsanity's APE anyways). I have plugged it into either port on the MacBook with the same result. I have also emailed motorola tech support. Additionally, I have done quite a bit of googling and have found other people with the same issue, but none of the suggestions have worked for me or were otherwise unworkable (some suggested downgrading to 10.4.9).
I have also heard of trying it in a powered usb hub, but the thing is, why does it work through the virtual machine if a powered hub is required? Or am I missing something in this?
I have purchased a Seagate 500gb 2.5 inch laptop hard drive to replace my feeble 120gb drive. I am trying to set up this drive using carbon copy cloner before changing it over, I'm using an external enclosure for this. The problem I'm having is the hard drive isn't recognized at all. It's not showing up in finder or disk utility so I don't know how to format the drive.
I'm using Leopard 10.5.6
The instructions that cam with the enclosure mention setting the hard drive to function in master mode, what does this mean? I don't want to go to all the effort of changing the hard drive if there's some sort of problem, and I would rather clone my drive before removing it too.
