Randy, This is perfectly normal. The a and c represent partitions (in the UNIX = sense of the word). The a partition is just the 1st partition on the drive and= the c partition represents the "whole" drive. The reason the mount works on both, is because in the case of your cd-rom= s the a partition takes up the whole drive. In the case of a harddrive the a a= nd c would generally be different, but I personally heard of a partitioned cdr= om (I could be wrong). Anyway, it is normal, take a look at man disklabel -Chris P.S. Sorry for the netscape mail, my regular work e-mail is down because = of that worm virus.
