Massive Data Loss Bug in Leopard
November 5 th, 2007
Update: The bug occurs regardless of the type of destination being moved to (whether it's local USB, local Firewire, SMB, etc.). Also, I have been informed that this bug goes back all the way to Panther.
Update 2: Here's a video of the same thing happening to a USB drive: leopardmovebug.avi
Leopard's Finder has a glaring bug in its directory-moving code, leading to horrendous data loss if a destination volume disappears while a move operation is in action. I first came across it when Samba crashed while I was moving a directory from my desktop over to a Samba mount on my FreeBSD server.
I've now run tests on a Windows XP SP2 SMB mount, as well as a local HFS+ formatted USB drive, and the bug surfaces every time the destination disappears while the Finder is moving something to the destination.
