I am using DropDMG 3.5.10 on macOS 10.15.4.
Trying to create a 50gb compressed image of a folder on my Drobo which has about 67gb worth of emails.
Each attempt fails and I receive this error message:
Error hdiutil: create failed - Operation timed out
At the end of the process I receive this response requested message from DropDMG
The disk you inserted was not readable by this computer.
Buttons: Initialize Ignore Eject
To ensure no other problems I choose ignore.
In preferences I did turn on Always run with root access but the check box does not remain checked.
I have successfully created smaller compressed images.
Any idea what’s going on?
