The speed of CD Speed...

I've backed up a bunch of data to DVD+R discs using my Plextor PX-708a and I
want to check the backups. I used the back-up program's integrity check, and
just to be safe, I'm running Nero CD Speed's file test and surface scan.

What I can't figure out is the latter two tests are only running at 2x. CD
Speed itself tells me its running at 2x and that means each disc takes about
an hour. The drive is certainly able to run faster so I'm wondering if
something is wrong or if CD Speed needs to run at this reduced speed to do
its work.

Any ideas?

Rick.

It shows that you should get 8x with a DVD+R disc.
Did you check the DMA settings?

That's one for the first things I did check. The transfer mode is set to
"DMA if available" and the current transfer mode is displayed as "Ultra DMA
Mode 2."

I can burn at 8x but the scan disc checks are completed at 2x. Granted that
the integrity checks do more than simply read the data, I didn't think
they're so much checking going on that it would have to move so slowly!

Try DVDInfo-pro, it's a great program and seems to be more "picky" about
errors than CDSpeed. BTW, the file check in CDSpeed is a waste of time, it
only verifies that the file exists.

I think the speed which is shown in the ScanDisc function only applies to
the file test.
It's normal that the file test is slower, especially if there are many
(small) files on the disc.
Reading files on a high level (ie. Windows) is just slower than reading all
sectors sequentially.

That is not true.
CD Speed reads the files completely.

And compares them with what? It only tells you they are readable, not that
they are intact.

Looks like a pretty cool program. Can you tell me something though? I'm most
interested in the DVD error test and while it does look thorough, I don't
know what errors it's reporting when a red block appears. Ideally, I'd like
to know when C2 errors and C1 errors are detected.

BTW, the file check in CDSpeed is a waste of time, it
only verifies that the file exists.

I'm not sure I can believe that because on a DVD of 13 350MB files, it takes
about a half hour to do the file check operations! Surely it wouldn't need
all that time to just make sure the files exist.

I gave DVD Info Pro a shot and while I like the program, its speed test
gives the same results. 2x across the board.

Now I'm getting concerned. I've been a bit freaked out at how the media
recognition is so slow (7 seconds with mastered DVD+R media) so maybe I've
got a bum drive.

Read speeds depend on what is being read. I think all DVD burners are pretty
slow to mount a disc, so that wouldn't concern me. Slow reading speeds *can*
be due to a poor quality burn, but can also be cause by the data itself.

As to DVDInfo, if you hit "help" in the testing window, you get something of
an explanation of what it's checking and how. It's pretty straight forward.
What is the data? Are you able to use the disc and copy the data, or
whatever you do with it? Try a movie or some other type disc and see how the
drive performs. You can use the speed test in DVDInfo to see what the drive
is doing on various type discs.
