I've always been able to do this on my mac. I type this in terminal defaults write com.apple.screencapture location /path/ and then log out and log back in and the default location of screenshots is changed to the location I select. I just set up a two disc RAID 0 and would like to change the location of my screenshots to this new disc. The problem is, it won't work for some reason. I can change it to any other location on my mac, but not this new disc array? I thought it was because it was in a RAID 0 but my other RAID 0 works just fine. Any suggetions?
