Select the disk location (it can be an internal HDD/SSD or a removable storage device) where you. I am trying to quick erase a CD-RW in El Capitan OS (version 10.11.1) but the erase option is greyed out within the Disk Utility window. Thanks for any tips on how to erase a CD-RW within the El Capitan OS.
Hello!
Why Can T I Erase Disk Utility Billing
I am running Macbook Pro (Late 2011) on Sierra osX.
First I repartitioned my HD into single partition(I had Bootcamp). After that I went to encrypt my HD using FileVault and it got stuck for days at around 60%. I think the problem might be something with repartitioning the HD but I see others have problem with encryption as well.
Starcraft 2 launch. I decided to reformat my HD to make a clean install(I have backed up the system with Time machine) after Disk Utility have failed to repair the disk.
Now I can not even reformat the HD using Disk Utility from CMD+R mode.
In Disk Utilty I see under Internal “Apple HDD HTS547575A9E384 Media” under which is greyed out my “Macintosh HD”. on Disk Images I see “Apple disk Image Media” which is 2.01 GB and has under it “OS X Base System”(1.29 GB) with option to eject which does not work. I tried to repair or erase “Apple HDD HTS547575A9E384 Media” but it does not work. When erasing it says “Erase process has failed” with details saying “Couldn’t unmount disk - Operation failed”.
What should I do?
Why Can T I Erase Disk Utility Disk
Either make the encryption in FileVault to continue the progress which didn’t work after reading about it and trying things… or to erase the HD and start a new install from my Time Machine backup. Any help is most welcome!
