In my previous project (4 years ago), I worked on HP/Philips' CDR/W drive's
(2600 IDE, SCSI 2x drive) firmware.
OPC is Optical (P something) Calibration. If the CDR program is designed
correctly (like Easy CD Creator), it issues the the calibrated command and record
the calibrated value and that CDR(W) disk ID in the PC. So the drive
doesn't have to recalibrate again if the same CDR(W) is inserted back for
packet writing or multi-session writing. CDR disk has limited (10) "calibration
area" to perform the this calibration procedure. When all 10 calibration areas are
used, you can't calibrate for that CDR anymore and you can not write to that
CDR disk neither. If you do disk at once or just writing a few session this is not
an issue. It is only an issue for packet writing or Track and once and you have to
reject and reuse the same disk > 10 times. CDRW disk can reuse the calibrate area.
You can try that drive with CDRW disk. But like Rogier Wolff said, it is very likely
be the CDR drive issue instead of SCSI/IDE issue.
