Files disappearing?

[obrien1984]

On several separate occasions, one of our users has had trouble with files "disappearing."

This only happens when she copies files between internal hard drives. After copying the files, she verifies that files exist in both locations. She then deletes the files in the old location. Then, newly copied files are missing from the new location.

I've never heard of this happening before, except for with improperly unmounted external drives. I have run disk utility and verified that there are no problems with either drive.

Could anyone help explain why this is happening or how to prevent it?

Thanks.
Joseph

If the file she is moving has a little arrow on the icon that means it is an Alias of the original file and not a copy.
