CCS specifies sense code 0x28 as "Media has changed" and sense code
0x29 as "Device has been reset". If you have a drive that uses ASC 0x28
to indicate a reset, then it does not follow the CCS spec and should not 
be advertised as a CCS drive.

I have never encountered a drive that displays the behavior you state.
