![]() If for some reason you are booting to an older macOS installer (pre-10.13), then you will need to click on the "Partition" tab within Disk Utility and select "1 partition" in order to "erase" the physical drive.īoth of these methods will destroy all partitions and volumes including Filevault encrypted volumes. You need to click on "View" within Disk Utility and select "Show All Devices" before the physical drive is shown on the left pane of Disk Utility. You want to erase the physical drive, but with recent versions of Disk Utility the physical drive is hidden from view by default. Please can somebody tell me how to wipe this drive! I'm starting to think it's a hardware fault with the SSD. ![]() I've also tried doing all this from Terminal from a USB drive set up as a Mojave installation disk, to the same effect. I note that during this process the fan is kicking in, which seems odd given I wouldn't think deleting a volume should be too computationally intensive. This happened on the encrypted or unencrypted volumes.Įventually after several reboots diskutil unmountDisk force /dev/disk2s1 worked to the point that the deleteVolume would get as far as "Deleting Volume" with an ASCII progress bar getting to 50% however after many minutes with no progress, the machine hangs with a black screen and has to be force-restarted. ![]() I then tried deleting the volumes individually ( diskutil apfs deleteVolume /dev/disk2s1) after five minutes or so I got "Error: -69888: Couldn't unmount disk". I then tried deleting the Container ( diskutil apfs deleteContainer /dev/disk2) this failed at the point at which it tried to unmount the volumes. I can ctrl-c out of this but the disk remains encrypted. Nothing seems to happen for several hours. I tried decrypting the volume ( diskutil apfs decryptVolume /dev/disk2s1 -user UUID) it accepts the password and says it's decrypting in the background but won't return me to the command line. ![]() There's an APFS container (disk2) with four volumes (disk2s1 to disk2s4). When I tried just running the Mojave install from a USB drive, it got to the point of prompting me for a password for the drive (it takes several minutes for the prompt to come up from the point I click Unlock.) and then just seems to hang, as if it's unable to decrypt the drive. However I can't wipe the APFS-formatted drive - each method I try I get a different setback. If I try to use Disk Utility from Recovery mode or a USB boot drive, anything I try to do with the APFS drive hangs Disk Utility, so I'm working from the Terminal in Recovery mode.Īt this point all I want to do is wipe the drive so I can install Mojave from scratch. If I boot into Single User mode I can't run fsck without it throwing up an endless loop of errors to do with spaceman_freed. (I can enter the Filevault password but the progress bar gets to 100% and then stalls. ![]()
