disk utility

Hi Guys, Ive tried booting in safe mode, verbose mode, repairing the disk (first aid) within disk utility and nothing. It used to be that the computer would get to the end of the startup progress bar and then shut down. Now it's opening the terminal upon every start and nothing seems to be...

[EDIT: I'm no longer having this problem. I erased the USB drive in Disk Utility, which caused it to mount. However, now it's not showing up on the Windows laptop I'm using, which seems like a problem outside the scope of this forum. I may just transfer my files another way. Thanks to those who...

About a week and a half ago, my computer froze and I restarted it and it would only reboot halfway. I then tried several different options in recovery mode (command+R) and nothing worked. I finally just erased the disk memory and was able to reinstall OS X, I lost all my files but the laptop was...

I was having boot issues where I couldn't boot into OSX. Thought the hard drive was bad. So I installed OSX on a flash drive, booted with that drive and used Diskwarrior to save my files. I purchased a new hard drive and tried 100 different times to format the drive using disk utility. It would...

Hi Everyone, What is this? I currently have no DMGs or any other devices mounted. Thank-you, Shawn

So before this gets deleted since it looks like other threads, please read into the present issues because I have searched everywhere for the answer to this. It's an iMac A1224 and I get the flashing folder/question mark on startup. When I booted from an install drive and tried to find the hard...

So I'm using the Disk Utility to erase free space on my Macbook (running Mavericks). I had 77GB available on my 750GB drive before I started this. It got about 80% through (using the 3-pass version) and then seemingly froze on "creating secondary temp file"--and my available space had plummeted...

Hello I am currently trying to make the partition Odin which is at 2TB to fill the entire 4TB disk and its free space, which resulted from me erasing its original second one. However, it does not seem that I am able to expand the partition so that it is taking up the 4TB because dragging on the...

Hi, My macbook pro has been acting up. It will allow me to log in, but will fail and shut down halfway through logging in. Single user mode (trying to use fsck -fy) showed that "The volume Macintosh HD could not be verified completely. Disk utility & disk verification is being a tad vague. It...

I'm trying to create a 6GB Cd/dvd disk image on disk utility. However, when it is created, it always shows up as having 1.5GB of space. Anyone know why this happens and how I can fix it?

I tried to put a clean install of OS 10.12 on my Mac. I did this by making another partition in DU, then installing OS 10.12 on it using the installer you can find download on the App Store, planning to delete the original partition. But, for some reason, in Disk Utility, I can't seem to delete...

So I recently used the disk utility to erase my hard drives as they were full and were slowing down my Mac by A LOT Now whenever I try to turn my Macbook Pro on, I am led to the recovery page even without pressing cmd+R. When I try to reinstall the OS, after I'm prompted to enter my apple ID it...

Hi everyone Does anyone know of a good 3rd party disk utility for OS X ? The original disk utility doesn't always fix my hdd issues, but when I plug it into a Windows PC it fixes it. The new El Captain Disk Utility is pathetic! Any suggestions will be appreciated.

I don't really know the best site for posting this, but i thought i'd try my luck here. I have just got a new external hard disk, the Seagate expansion, and i am trying to format it to work on my mac. I was told that i had to erase the disk and format it to OS X Extended (Journal) with the Disk...

Hi folks, I really need some expertise on this one! I had OS X El Capitan and Windows 10 (bootcamp) installed on my MacBook Pro. Today i tried to boot Windows, and a screen appeared saying it couldn't boot, so i used windows 10 installation disk to "Fix Startup Problems". After it supposedly...

Hello. Weird case. I have purchased a second hand power PC Mac G5 but don't have the Disk Utility installed. I wanted to know if it's possible to install this utility. I think could be a permissions problem also. If nothing works, I want to reinstall Leopard. What version is needed? The...

Hello!, So I renamed my a third FAT partition, on my internal SSD drive from "Untitled" to something more professional (because I have clients that work over my shoulder). The partition was intended to be used for bootcamp. I ended up temporarily having to put some files on it. After renaming...

Hi, new member here, So I have recently purchased a LaCie Big2 12tb HDD with RAID. This is to go with my iMac that has a Bootcamp Windows partition generally used for playing games. What I want to do is use the LaCie drive in a RAID 1 configuration for the OSX partition. I then want to create...

Hello all, **Lots of detail below. At the end is a TL;DR if you'd like to skip to that. TIA.** A week ago I noticed my 2011 MBP (Mountain Lion) was acting sluggish, slow to respond with static on one of the windows (when I opened it up and logged in, the first program on the screen would...
