Comment 20 for bug 584052

I think this is now worse. Now I can't even mount the drive from the command line:

$ mount /dev/hde -t iso9660 /mnt/cdrom
mount: block device /dev/hde is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hde,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

$ dmesg | tail
[ 2515.575187] Buffer I/O error on device hde, logical block 9
[ 2515.581199] hde: command error: status=0x51 { DriveReady SeekComplete Error }
[ 2515.581214] hde: command error: error=0x50 { LastFailedSense=0x05 }
[ 2515.581223] hde: possibly failed opcode: 0xa0

[ 3280.675137] isofs_fill_super: bread failed, dev=hde, iso_blknum=16, block=16

It still shows up in lshw and I have no problems with the drive when booting into OS X.
