I ran into an issue with at least a few CD's where the access to them mounted as cd9660 was very slow. dd of /dev/cd0 was also slow. However, if I run readcd (from cdrtools-devel-3.02a06,1) at least once, which would run at full speed, then any access to the disc whether mounted or not is at full speed. I do not recall this happening in the past, but this is with a newer computer (i.e., newer drive). It appears to be that something is determining the full speed correctly when readcd is run and is keeping that state until the disc is removed while mounting or running dd against the drive does not. OS: 10.3-STABLE (r304921) amd64. pass0: <HL-DT-ST BD-RE WH16NS40 1.00> Removable CD-ROM SCSI device pass0: 150.000MB/s transfers (SATA 1.x, UDMA6, ATAPI 12bytes, PIO 8192bytes) Any ideas?
