Presently I am attempting to back up my whole computer's primary hard drive to an ISO file. When I attempt to do this using Disk Utility, I perform the following steps:
- Open disk utility and choose the disk I want to create an image from in the left pane.
- Click on File->New->Disk Image from "MyDisk"
- Then I choose Image format->DVD/CD write master
Disk Utility runs for a long time, then as it nears the end of the operation it gives me the error "Filename too long" and quits.
As an alternative, I attempted to create an ISO file using hdiutil, but receive an error after the file reaches a size of 2 GB:
sh-3.2# sudo hdiutil makehybrid -iso -o /Volumes/Grieg/ChopinSnowLeopard.iso /Volumes/ChopinSnowLeopard Creating hybrid image... hdiutil: makehybrid failed - Operation not permitted
If I try this alternative command, I receive a different error:
sh-3.2# hdiutil create -srcfolder /Volumes/ChopinSnowLeopard /Volumes/Grieg/ChopinSnowLeopard.dmg diskimages-helper: DI_kextDriveDisconnect returned 268435459 ((ipc/send) invalid destination port).
Does anyone have any suggestions on how to resolve either of these problems? TIA.
