Making Bootable USB Installer (Monterey) - USB can't be erased
Hello,
I'm trying to make a bootable USB installer for Monterey using these interactions Create a bootable installer - Apple Support
The USB can't be erased though. Does anyone know what's causing the error?
Annas-Air:~ xxxxxx$ sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/ADATA UFD
Password:
/Volumes/ADATA is not a valid volume mount point.
Annas-Air:~ xxxxxx$ sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/ADATA_UFD
/Volumes/ADATA_UFD is not a valid volume mount point.
Annas-Air:~ xxxxxx$ sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/ADATA
Ready to start.
To continue we need to erase the volume at /Volumes/ADATA.
If you wish to continue type (Y) then press return: Y
Erasing disk: 0%... 10%...
Error erasing disk error number (-69888, 0)
An error occurred erasing the disk.
I also tried erasing the USB in Disk Utility, but that won't work there either..
Also when I plug the USB in first, Disk Utility won't list my disks and USB. If I open Disk Utility first though, then plug in the USB, it will list my disks and USB.
Thanks very much.
