The incrementing of ataX is unrelated to anything else...  Each "new" 
ata interface gets a new id.

"failed to stop engine" is where the driver is attempting to talk to the 
card, and gracefully shut things down.  If the card does not exist (ie. 
has been removed/ejected), then this is normal behavior.
