Leopard Revives Data-Loss Bug From OS X 10.1

Pete Mortensen (10:01 pm PDT, Nov 5th 2007)

Buying an Apple product on the first day it’s available is a recipe for disaster. This universal truth was reiterated today as Macintouch reported a nasty bug in Leopard where if you move a file to an external drive and then unplug the drive before it finishes copying, it will delete the file from the source and the destination drive.

In our test, we used Command-drag to move several large folders from a MacBook internal drive to an attached FireWire 800 external drive. While the folders were being moved, we disconnected the FireWire cable. The folders disappeared from both drives!

Yikes. Not an incredibly common flaw, but definitely easy enough to do that it should never show up in a shipping product — especially because it was present in OS X 10.1, and not inTiger. That’s a step in the wrong direction.

Thanks, Andrew!
