I had a similar problem with a Sandisk 32GB SD card. I solved it with the Windows management disk. I erased all partitions of the disk and then created a fat32. Initially no drive letter was assigned but then from My Computer, format the drive without problems. My SD card had this problem after using it for a raspberry pi.

If I'm understanding you correctly, you are trying to format a linux partition from your OS X diskutil app. Far better would be to access it via an external linux boot device, either USB or DVD. Since what you do to that partition as far as a reinstall of linux should (fingers crossed) only mess with the linux partition, your ability to later on reboot into ...

To run a whole-disk repair, you need to do it from the command-line: diskutil repairDisk /dev/disk1 Be sure to use the correct disk identifier (in this case it was /dev/disk1); in diskutil list you're looking for a disk marked physical in order to specific the entire physical disk (i.e. not a logical disk). If you incorrectly use a logical disk identifier ...

Select the parent of disk0s2 in Disk Utility and try the erase operation again, at least twice if it doesn't work first time. If that works, proceed with the reinstallation of OS X.

I ran into this same issue trying the same thing on Mojave. It appears that ACLs on symlinks just aren't supported when working within the confines of disk images. I did come up with this workaround though: Create a blank sparse image that's big enough to hold the backup. ditto the backup directory into the mounted sparse image. It will make the same ...

This will clear all the data on your drive! You can erase the whole volume by clicking the View button and choosing Show All Devices. Then select the top-level entry and click Erase. Set it to APFS and GUID and click Erase. Name it Macintosh HD (or whatever you prefer if that's not your preference). Then run the installer on your new Macintosh HD and you'll ...

Ah HA! Well it took about 24 hours to figure out, but the solution is to: Boot into recovery mode Open disk utility Select the internal drive in the side bar Find the "+/-" volume button in the toolbar and select the "-" volume option. The appearance of the internal drive will change in the sidebar. Select the root (top level) of the drive in the sidebar ...

My answer will be helpful for those who are upgrading their SSD. Personally, I had a MacBook air early 2015 with 128 GB SSD. While upgrading to 512 GB SSD, it was not detected in the internet recovery mode. I tried both Disk Utility and Terminal commands. Finally, this method helps me to fix the issue. https://techiestechguide.com/internal-ssd-is-not-showing-...

Your disk has a capacity of 250.69 GB with 211.9 GB used leaving 38.8 GB. The reported free space is 74 GB but 37.5 is purgeable. Purgeable space on a Mac is space that the Mac considers save to clean up. So while it says you have 74 GB available, 37.5 GB is currently in use but is safe to erase and clear off..

You cannot partition a volume. You must partition a drive (device). To do so, click on the drive itself, located just above the partition you selected on the sidebar ("Samsung Portable..."). Then, you can partition the disk. Edit: Back all data you want to keep up and Erase the disk as GPT (GUID Partition Table). Newer versions of DU for some reason don't ...

Please note that although both outcomes are the same whether encrypting with Disk Utility or Time Machine, Disk Utility takes significantly longer. Perhaps this is because it is encrypting the unused free space and TM is not. Can anyone else corroborate? Also, in Terminal you can simply use this command to show TM volumes & status: diskutil cs list

and I get "disk out of space" on a Terminal where I copy the files with cp -r. I suggest using the ditto command. You can use ditto to copy directory to directory. It includes all nested directory. No idea how links would work. Would the source disk be timemachine disk? It uses hardlinks which result in a copy of the data being made for each hardlink. ...

This should work but I haven't tried it and you should use at your own risk obviously change the [volumes] mv ~/[Volume1] /[Volume2]/Backup/MyFolder

Unlike some installations of some operating systems there is no OS level uninstall feature in macOS. That is true for applications, though some do have uninstallers available. That is true for minor OS version upgrades, EG 10.14.1 to 10.14.2 That is especially true for full versions, EG 10.14 to 10.15 What that means is that if you install an OS update ...
