Indeed, my drives had a 'SC_ONE_LU' entry in the old scsiconf.c file.

It seems that the PHILIPS CDD2600 reply 'not ready' rather than 'medium not present' to the READ CAPACITY command if the medium is not present. > If increasing the bus settle delay doesn't fix it, there are other things > we can do that will probably fix the problem.
