Comment 42 for bug 901215

'safely remove drive' via rightmouse. And it went off then came back!!!
More than once! And a rightmouse safely-remove-drive got a message about busy!
Waited a few seconds. Another 'safely remove' worked and as soon as the icon on desktop
went off I disconnected and all seemed ok. AFAICT.

One item possibly of interest: both cpu cores running 100% (seti at home) so
timing issues might show up.
