Hi All, I was trying to fix the problem about "not properly unmounted message " with Sleepwatcher. I use this script from another thread : #!/bin/bash if [ -d /Volumes/Name_of_HDD ] then /usr/sbin/diskutil unmount /Volumes/Name_of_HDD fi When I run it in terminal , it works well. But when I press sleep button, my desktop turn off very quickly and I still keep getting this error message. My .wakeup is okay. Thank for any help!!!
