You've got SCSI bus problems. Either you don't have things cabled correctly
or you have bad cables or you have bad terminators. The drive is running at
40MByte/s because it is running in SE mode instead of LVD mode (which is
required for 80MByte/s operation) and the CD-ROM is running in async mode most
likely due to transfer errors on the SCSI bus at any higher sync speeds.
