Hi, I also tried the Disk Arbitrator, but I don't like loading even more unnecessary utilities, so instead I use the fstab file. Create a textfile called "fstab", no .txt or other extensions, in the /etc directory, and put one line per volume that you don't want to automount.
UUID=put-your-uuid-here-xxxx-xxxxxxxxxxxx none hfs rw,noauto You can look up the actual uuid from Disk Utility too. If you use multiple systems on external disks/pendrives/partitions, copy the fstab file to their /etc directory too to prevent slowness/further data corruption. But beware, the rescued image will have the same uuid, so it will also prevent mounting that. You can change the volume UUID on the copy (or on the original disk if you are brave), see here: http://superuser.com/questions/485105/unable-to-simultaneously-mount-hdd-and -its-copy-on-osx koll PS: I re-CC-ing this email to [email protected], maybe others find something useful in these emails. From: John So you check your disk identifier using Disk Utility? Hmm... I didn't know that was possible. I just looked and see that it *is* possible. I use the terminal and do diskutil list Do you use anything like Disk Arbitrator? Thanks again. John koll wrote: > The && symbol executes two commands.
