// Device states - To guard against races during trasitions to and from
// standby mode, a disk starts in the STATE_INITING state.  Upon entering
// standby mode, a disk goes into the STATE_DEAD state and can no longer
// be used.  Coming out of standby mode, the pcmcia system will force a card
// removal and this driver will get unloaded.  Between the time the device has
// left standby mode and the card removal notice gets generated, the disk 
// should not be used at all, since as the driver is unloading it unmaps the
// ATA registers in pcmcia I/O space.
