FYI, this error code means "Not ready; medium not present". It refers to the fact that you don't have a card inserted in the card reader. > According to: > dmesg|grep 'usb-storage: -- code:'|wc -l there are 73 of them and its not > incrementing the count, so I'd assume its either actually quit, or that's the > size limit of the ring buffer.

The HAL daemon does this. It polls devices with removable media (like card readers) 4 times per second to see if you have inserted anything. > And the drive has not spun up.

You could turn off HAL. But it looks like you don't need to...
