Unhappy Plextor Problems!!!! [; ; winME]

sponsored links
Just bought a new 40/12/40A Plexwriter to put in my system with my old 12/10/32A , I've noticed a couple of people on here with similar problems , but none seem to have found a solution!

I was planning on using the 12x for reading and the 40x for copying , the 40x is set as a master and the 12x is set as slave.

Here is my list of problems:-
1. CDRWin (4.0a) won't recognise the 40x
2. Really slow copying
3. Really slow reading
4. Nero reports upto 150 avoided buffer under runs when burning a 80 minute audio disc.

Think thats about all !!! I couldn't wait to copy at faster speeds but its just altogether slower.

The discs I'm using are 24x verbatim and I've been trying to burn at 16,20 and 24x.

Any help would be gratefully appreciated , thanks in advance.

First, you should be posting this in the CDR/ROM forum.

Second, CDRWin only works with the supported recorders, I dont think the Plexy 40x made it to the list yet.

For starters the Plextor 40x burner is designed to burn Audio at a max of 24x (this is stated in the specs). Then in order to burn at 24x, the burner starts at a zone of 16x. Unfortunately the 12x Plextor burner does not start DAE fast enough to support this it starts at 14x. It will be at least 30% into the CD before it achieves 24x. This is where the buffer underruns are probably occuring.

If you want to burn at 24x (about 22.5x average) on the fly, you will need a faster reader. Not sure why your drive would be reading slow. Have you benchmarked this. It should be faster than your old Plextor. Download the speed test (Data and DAE) from [url][/url] and run the test. You can also check for CD drives that start DAE at 16x or more.

I'm not suprised that CDRWIN doesn't recognize a drive just introduced. However, check your ASPI layer (CDRWIN gives you the option to use the system ASPI layer or ASPI drivers installed by CDRWIN). Also make sure DMA is enabled.

Duffy is correct as usual. I'm going to move this to the cdrw forum for you.

Thanks Elaine!

Sorry ,I thought it was a system problem.

I've checked my ASPIs (sounds painful!) and they seem to be upto date , in my CDRWin devices and Setting Box it will only let me select the option to 'Use the Aspi drivers installed by Microsoft or Adaptec' it won't let me select any Golden Hawk drivers.

I'm not trying to burn on the fly , I'm temp imaging first.
DMAs are all on.

Any more suggestions? I think its gonna be a late night!

You stated you were using the Plextor 12x for reading and the Plextor 40x for copying. This sort of implied that you were copying on the fly. If not you should use the Plextor 40x for reading and burning since the Plextor 40x is also the faster reader. Run the CDSpeed tests as suggested and post the results. This will give us a clue as to what the read problems are. What speed can you burn data at without Burnproof kicking in?

Also make sure auto-insert notification is off.
