I have DVD-RAM/PD drive (LF-100) and its performance, especially
writing performance, become very bad in linux-2.2.16.
Up to 2.2.15, scsi.c was responsible for the DVD-RAM driving. I found
this is changed in 2.2.16. In 2.2.15, I could make partitions to the
the read/write performance was not very bad. At lease I could do other
jobs while copying to DVD-RAM. But in 2.2.16, fdisk says that I have to
set heads sectors and cylinders manually, which I do not know, and
when writing a 600MB class file to PD, the foreground job can be quite
a lot disturbed by the copying.
Please let me know how can I help to solve this problem. Thanks.
