Mine does the same thing, and it's harmless.
As I understand it, the device claims to be an IDE drive.
Linux assumes that a removable IDE drive will be a CDROM drive, and
tells it to close/lock the drive door. Not having a drive door, it
complains.

Presumably the appropriate code (I'm not sure if it's pcmcia-cs or kernel)
needs to be told how to distinguish between devices with & without doors,
and not try if the door isn't there.
A side note: I've had some trouble after unmounting and ejecting my CF
card, in that Linux complains about a lost interrupt. This tends to cause
filesystem corruption as well, so I recommend the workaround of only
removing the card when the laptop is powered off.
