    I am wondering if anyone else is having issues creating a bootable usb stick using Disk Drill 3.1.817 Pro and Mac Sierra (10.12.5)

    I have tried an SD card and several different USB keys including pulling my ESXi USB boot key and I keep getting the same following error code.

    Disk Drill failed creating bootable disk with error: Can’t mount device disk0s3 to path /var/folders/8v/wx9v80bd2fb7lswq307c1gh40000gn/T/btdkgGsAKfeV/r. Process exited with nonzero status 1 – please try to reattach the destination drive and/or reboot your computer.

    I have rebooted my MacBook Pro several time as well and this is stumping me.I am using a USB known to be bootable and when I click make bootable I get an error.

    Is there another way to create the boot key?

    Unfortunately, we are confirming this with the latest macOS. A lot has been silently changed by Apple in Recovery HD which is the basis for boot drives created. We are actively looking into this issue.


    Please check out the newest release, Disk Drill 3.2 (macOS). The issue with the boot drive creation has been fixed: https://www.cleverfiles.com/getdiskdrill



    Haven’t had a chance to update the thread. Thanks for putting the fix out there so quick. I downloaded the update and was able to create the bootable USB stick. 🙂
