Comment 4 for bug 486024

Sequence Clarification:

Attach drive > Popup box to decrypt drive > Drive mounts and shows on desktop.
rsync data to drive
Some time later - minutes or even hours.....
Right click drive on desktop > "Safely remove drive"
Sometimes there is an animated popup asking to wait while the file write is completed. Some times there is no such popup.
Animated Verification of write complete or not -
the error message of "device busy unable to unmount" always pops up, but the device is in fact unmounted.
If I remount the drive and rsync again, there is no indication that a file did not complete the transfer.

Just a thought, but it could be rsync that is holding something open, or perhaps "cryptsetup luksclose" gets hung up.
