hdiutil: create - No such file or directory

I am trying to create a dmg of the high sierra Recovery HD partition, using terminal,
(going to create a bootable USB with the Recover HD stuff by 'restore'ing from this dmg)

but this command

sudo hdiutil create -srcdevice disk0s3 ../RecoveryHD.dmg

and

sudo hdiutil create -srcdevice disk0s3 RecoveryHD.dmg

(and other variations, all executed from the desktop directory)

gives

hdiutil: create - No such file or directory

MacBook mid 2012 High Sierra. I am missing something stupid here, but no idea what

Try the following:

sudo diskutil mount /dev/disk0s3

df | grep disk0s3

It actually mounted the Recovery partition (on High Sierra), where you could create a .dmg from the mounted Recovery file system.

On the High Sierra system, I have access to, /dev/disk1s3 was the recovery partition (It is an SSD based Mac). When I mounted it, it appeared as /Volumes/Recovery and an ls on the mounted file system shows:

ls -Rl /Volumes/Recovery

And then I was able to create a .dmg using

sudo hdiutil create -srcfolder /Volumes/Recovery Downloads/tmp.recovery.dmg

...................................................................................................

created: /Users/raharris/Downloads/tmp.recovery.dmg

ls -lh Downloads/tmp.recovery.dmg

-rw-r--r--@ 1 root staff 492M Jul 11 22:15 Downloads/tmp.recovery.dmg

Does that help?

This is an educated guess.

If you just want to do that, you could try single user mod.

This page will tell you how to get into single user mode.

If that don't work, try a network boot

option + command + r should work. power off. hold down option + command + r key. power on. wait to see icon.

my experience in 10.10.3. I double the problem is with hd.dmg. that leaves /dev/disk0s3

mac $ sudo hdiutil create -srcdevice /dev/disk0s3 HD.dmg
Password:
hdiutil: create failed - Resource busy
mac RC=1 $
mac RC=1 $ diskutil list /dev/disk0

   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

This hints at it /dev/disk0s3

mac $ dd if=/dev/disk0s3 bs=409m | dd of=~/disks0s3.binary

Did you try network boot?

How about booting from an external drive? Then run the command on the internal drive. This should get around permission problems.

Perhaps somewhere deep in the software apple dropped the reference to /dev/disk0s3.

Perhaps it not letting you do the command on hidden partitions?
