You need to find out. You may not believe it but one of the major
reasons for write failure is using a disc brand & product rev. not
on the list recommended by the drive manufacturer. Most drives will work on
some discs but not on others.

Download this little proggy and get the disc brand name.

then check the discs that failed against the drive manufacturers'
recommended disc brand.

As long as you have supplied enough buffer space for the data
set NO_QUEUE_FREEZE on the SRB.

all brands.
