Comments on: SuperDuper Bash Script to Automatically Mount or Unmount a Hard Drive

Sounds like a good solution!

SuperDuper's developer once told me that the app should mount and
unmount the drive itself (assuming it was attached-but-unmounted when
SD starts) but I haven't tested that myself.

I've been using your script for a while: thanks. However, a few days ago it stopped successfully unmounting the drive being copied to.

I checked, and the line

diskutil unmount "$DRIVE_NAME"

was given the right drive name, but then complained that a completely different partition couldn't be unmounted.

I finally fixed it by changing the line to

disktuil unmount "$DEVICE"

This seems to be authoritative and unambiguous, and works. I expect it should work for others, too, although I'm still not clear why things stopped working.

Thanks,
Dan

Hrm. I don't know why it requests your password. I used that command specifically because it does not request my password. Sorry I don't have an answer.

Excellent script, thanks. I clone my main drive to a backup in my Mac Pro every evening. Your script will solve a problem I’ve had for a while where everything’s duplicated in ‘Launch Services’ because OSX finds all the duplicate applications on my clone drive. The only thing I can’t solve is that the disk mount requests my password, and therefore I can’t leave the automatic clone update to run unattended. Do you have any suggestions for this?

a) I don't think my script is necessary. The developer said that SuperDuper will automatically mount/unmount the drive if needed

b) ~ is a Unix short cut for $HOME

c) You probably need to get into Terminal and paste this command (including the " marks!) Make sure it is ALL ONE LINE:

chmod 755 "/Applications/SuperDuper!.app/Contents/Resources/Copy Scripts/unmount-for-superduper.sh"

OOps.

My bad. You can simply run this command:

touch ~/.source

I get the error:

| Error | /Users/Fred/mount-drive-for-superduper.sh: line 42: /Users/Fred/.source: No such file or directory

What is this invisible file? And how can I generate it? Thank you for your help.

You’d probably also want to make sure that the drive name is unique, so you don’t get it mounting with a trailing number that may not correspond to the script.
