It's possible that if your drive experienced errors, it may have reverted to PIO mode. Check your transfer mode in Device Manager under IDE controllers.

sorry, the problem still exists.

First i did'n know what PIO was so i lokked it up. Seems that you can choose between PIO and DMA (which i do know a bit) but the IDE controleer was configured at (Use DMA, if available).
I couldn't find it in BIOS-setup system either but aparrently you can choose between 3 types of 'speed'-PIO. Can't choose it or can't find it.


Perhapts omething else

It might help is you posted what system you have. Does system setup report your drive correctly?

I seem to be having the same problem...

Just received a new Dell Demension 4700 with the philips DVD8701. Worked fine with Nero and was burning dvds at 16x. After about 3 or 4 burns, the drive has now dropped to 2x. Can't figure out what is wrong with it or how to get it back to 16x.

Dell support was not much help and has recently replaced the drive. Unfortunately, the exact same thing is happening.

Any thoughts?

I found a solution.
Apperntly, the driver has a kind of bug in it.
the solution for is going to your device manager and then to IDE ATA/... controllers.

There your have a main one (primairy) and other ones

uninstal the other ones and reboot your pc. Windows will detect these again and will reinstall (correctly this time) your dvd-writer

The main problem is that the dvd-writer has two modes, DMA and PIO and that the DMA v2 is not available. If you let windows reinstall this, it wil redetect this mode and adapt your writer's read and write speed

This workerd for me, i'm back up running at 16x

Let me know if this helped for you to...

Scuba:

Thanks alot for the advice.  I'm at work now but will try it first thing when I get home.

Will let you know.  I'm keeping my fingers crossed!!

 

Thanks again.

Scuba:

Thanks for posting that.

Thanks again for the advice.  I think that did the trick.

After burning about 6 dvds, the speed has been pretty consistent.

Thank Goodness for this forum!!!!

 

 

 

I also had this problem and it is a problem with Windows XP. Microsoft has an article that describes how you can permanently fix the problem. You must have SP2 and you have to add a registry entry to activate a fix in that service pack.

Article is here:

Title: IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur

There must be a LOT of people out there experiencing this problem. Wouldn't it be nice if Dell's automatic support tool fixed this for us?
