SATA card-reader unusable after eject? (was: Nashua LUG and linux question)

[Mac]

Thanks for coming up with a good subject line. I knew mine was lame. :)

If I use "Eject" the device /dev/sdf1 remains with leds on, plugging
the SD card back in mounts the device again.

If I use "Safely Remove Drive", the device disappears and leds out.
Pluggin the SD back in results in nothing.

Regards,
Mac
