Two related(?) problems: slow dvd write & no enable dma checkbox.


E

electron

1) When writing to CDRs or DVDRs Nero writes more slowly than the
maximum
speed allowed by the media in question complaining that it cannot read
the data from the hard drive fast enough to write at a higher speed.
For example, in the case of DVDRs it will fire up at 4X (5520KB/s) but
drop back to 2X. A SiSoftware Sandra speed test on the hard drive
indicates that it can transfer data at 46MB/s. The "hard drive" is a
set of two Maxtor Diamond, 7,200 rpm, 80gig drives in a Raid 0
configuration.

Well, it seems to me that if the hard drive can transfer data at
46MB/s and the burner at 4X would be writing at 5.52MB/s the hard
drive speed should not be an issue.

Anybody have any ideas about speeding up the burning process?

2) When I presented this problem in the .cdr group, someone suggested
that dma might not be turned on for the dvd drive channel. So, I went
into device manager and looked at the primary and secondary channels
in ATA/ATAPI controllers. These windows each have only three tabs:
general, driver, and resources. My understanding is that there should
be five tabs, one of which (advanced, if memory serves) should have
the "use dma if available" checkbox.

If anyone has ideas about either or both of these issues ....

Thanks, but the Promise Raid reporting utility reports that they are
operating on UDMA Mode 6.

I think I've figured out what's going on with regard to #2. The
computer has Intel Application Accelerator software installed and it
controls the primary and secondary IDE channels. That software
reports that the DVD drive is operating at UDMA Mode 2, which is 33.3
MB/s. But that still leaves #1 -- why is the burner slow.
Incidently, the NEC burner I was using previously also had the same
problem.

Check this information on the Intel website: http://tinyurl.com/4vjzt

My initial feeling is that Application Accelerator is the culprit. I
would uninstall it and see if the problem goes away.

Thanks for the pointer. It sounds promising. I'll try it out next
time I'm going to burn a dvd or cd.
