I do not believe that it is a termination problem.
The transfer speed of the u2w disk was reduced to
40 as in the scsi bios negotiate wide was switched off
for the host adapter (id7) and as suspected this
limited everything to 40.
But the problem with the CD´s is still present.
Probably it is a problem of the cd driver.

now with the new version the transfer rates of the CDs are
quite different and the plextor is switched to async again:
