>From julian@jules.DIALix.oz.au Fri Sep 10 22:58:30 1993
>Date: Sat, 11 Sep 93 12:59:39 +0800 1/ fix bug where cd0a was unusable because it was compared against the number of 2k blocks not the number of 512byte blocks.. gave an error for all reads past 1/4 way through the disk (cd0d was ok). 2/ fix open code so that it now notices if a disk has been changed and updates the disklabel. 3/ use the new error handling code from st.c 4/ start adding stuff to get ready for using cd_scsi_cmd from cd_start (like is done in st and sd) 5/ more general cleanups including making dmesg report sector size of disk.. (believe it or not SUN drives use 512 byte)
