Mac Disk Utility Not Enough Space On Device For Requested Operation


Are you having problems with your external hard drive changing to different format and saying MediaKit reports not enough space on device for requested operation when reformatting? How to change default save location for excel for mac.

I started up the Disk Utility and tried to Erase it and make it APFS, but every time I try, I get the following error: MediaKit reports not enough space on device for requested operation. After several attempts, I tried formatting to HFS+, and get the same error.

Aug 09, 2016  This is a guide which I decided to make after solving the problem 'Media Kit reports not enough space on device for requested operation' on my laptop. Problem: Try to format a partition for installing Mac on your laptop, but it reports the above problem. Purchased a 3Tb MY BOOK External Drive today. Following site procedures for reformatting to Mac OS Extended (Journaled) and erasing the disk using Mac disk utility, I received the message “Unmounting disk MediaKit reports not enough space on device for requested operation. The Mac can see the Windows partition but when I try to format the parition for Time Machine, Disk Utility says: Volume Erase failed with the error: MediaKit reports not enough space on device for requested operation.

Tried formatting it in a different format, like exFat, Fat32, but the same error. Tried reformatting an already created Mac OS Extended Volume(Journaled). Tried formatting/reformatting/partitioning using Terminal but no success.

I was having problems with the external drive where I store my Time Machine backups, so I tried plugging and unplugging the drive (per earlier advice, and something that had worked in the past), but could not mount the drive. I ran Disk Utility and tried to verify the disk, which told me the disk needed to be repaired. I tried to repair the disk only to get an error message that Disk Utility could not repair the disk and it needed to be reformatted. So I tried to erase the disk with Disk Utility only to get the error message 'Volume erase failed: Media kit reports not enough space on this device for requested operation'.

But since I don’t need the Boot Camp, I didn’t even try this. My final solution takes a few hours and is very straightforward: 1. I backed up all the data on my internal drives to an external hard drive. I also made an up to date Time Machine backup of my primary OS X partition to restore it later on; so I didn’t have to install the applications all over again.

I'll fill in details first. System specs: ASUS Z170-Pro Gaming Intel i5-6500K Corsair LPX 2600Mhz DDR4 8Gb RAM Current partitions: UEFI + GPT 400 Mb Recovery partition 100 Mb EFI (problem area) 16 Mb MSR 80 Gb WINDOWS 30 Gb Linux Mint 50 Gb Mac (reserved space) 200 Gb Storage 105 Gb Data Problem: Can't install Sierra due to above error. Possible solution: Using Gparted I can shrink Recovery partition by 100 Mb (has over 150 Mb free) and add to EFI and delete MSR partition altogether. (Caveat is Gparted gave some warning about 'possible' booting issue if Recovery partition is resized) OT* Does MultiBeast El Capitan work on Sierra? *OT Kindly advise me.

Please See • Click the Eject button next to the external hard drive volume (My Passport, etc) • The drive will now be greyed out • Click the Erase button • Choose a new Format: Mac OS Extended (Journaled) Choose Scheme: GUID Partition Map • Type the drive new Name • Click the Erase button • When finished, the drive will be formatted and repartitioned successfully. Click the Done button.

(I am dual booting using Clover). In the following procedure, I had my windows working, in case,if you can't boot your windows or have problem related to booting, probably the same solution can be applied, as it creates a new bootloader.

And on which disk? Disk where I've installed Windows+Linux or disk where i plan to instal MacOS? And after Mac installation will I be able to run all three systems? Will they appear in clover if they are on separate disks? What will happen to GRUB? PS All systems are in Legacy bios mode.
