asus dvd drive issue

I know this isn't the place for a dvd problem but I ran out of places to
seek help.
I have an asus dvd drive that is supposed to read at 48x. I have been
importing music cds into itunes and at first the reads were reaching 40x
which I was quite happy with. I had stopped importing music to copy some
data from other dvds. One of the dvd was defective and the copy returned
a checksum error. One note is that during the copy of this disk the copy
froze for a long time at the point of the error before the copy finally
returned the error. I then resumed importing music cds into itunes. At
this point cds were no longer being read at ~40x but now were being read
at ~7x. I tried to reinstall the driver with no luck. I also tried using
Nero's DriveSpeed program to set the speed back to 48x but that didn't
work.
This is a sata drive if that might have anything to do with anything.

if either you can help or know where I could look for help for help I
would appreciate the feedback.

thanks

john

When windows detects a data error (such a CRC) on such devices,
it can drop the operating mode of a device from a UDMA (fast) mode
to PIO (slow) mode without telling you.
What version of windows are you using?
If it is this, what might work is to remove the device in Device Manager
and reboot. Windows will re-detect the device and re-install the drivers.
HTH,

I am running windows xp.
I did try removing the device from the device manager, rebooting and
adding the device. this did not seem to do the trick. It does seem to be
what you describe though. I thought that by trying to read the disc with
the error it put drive into another mode. That is the only thing that
makes any sense. I can't seem to find anything on what that might be.
Argh!

thanks for the reply

I missed the fact that it was a SATA drive when I first replied. Hmm,
not sure how the access modes work with SATA optical drives - PIO
mode only relates to PATA, AFAIK.
I'm wondering if one of the two (one frequency for CD, another for DVD)
lasers has degraded. If it works near full speed with DVDs but slow with
CDs, it could be that I suppose.
HTH,

well considering new drives cost $25 it seems like a new drive is the
answer. At this point I am more curious on what happened and I can't let
go of an unsolved problem. I repeat, argh!

Maybe the read heads are just dirty? You could try one of those cleaner
CD's...
