New 40X CDRW won't write at 40X

Where did you see the VPW BIOS? I only seen the current VOW on Acer site.

I un-unstalled Nero and re-installed same problem. I tryed the same CD with Music Match and gave same results.

There is a new BIOS VPW and it is a windows flasher. I flashed the burner and was finally able to burn one of the CD's at 40X where as before Nero was only allowing 16X.

I have noticed the writing of the leadin and leadout is still slow. To complete writing 699mb took 3:47 but stopped writing data around 3:17 so took 30 seconds to do the closing of the CD.

I hope they fix this also as my 24X TDK will finish at about 4:08 total for a 700mb. Not a real big deal but I would think the difference between 24X and 40X would be more then a 20 second difference.

Rangove,

no 40X drive writes at 40X for the entire CD. 40x is the maximum writing speed.

They all start at a lower speed at the inside of the disk and increase to the outside. There are 2 ways of achieving this - Zone CLV (Constant Linear Velocity) and PCAV (Partial Constant Angular Velocity).

Zone CLV writers start at a set speed on the inside (maybe 24 or 20 depending on the writer) and after a preset time they step up to a higher speed. Finally they write at 40x.

PCAV writers start also at a lower speed, but they increase their speed continuously till 40x and then continue at 40X until the end of the disc.

The ACTUAL speed of the writing will depend therefore on the technology used, and the time at which the drive switches to 40X writing.

Drives rated at 40X will also deliberately burn certain discs at a slower speed if the drive believes that the disc isn't up to reliable 40X burning. Most 40X drives have these "features".

I cannot cd-copy on the fly. When not on the fly, it copies only at 4X.
Woeque,

Is your Drive in UDMA mode? It sounds as if your drives are running as PIO. That would explain your transfer speeds.

To: BIM2k and others,

Yes, it is on UDMA mode. VPW firmward is on BENQ site to those who interested.

Rangove, did you flash the VPW on your MSI?

Yes I flashed the drive. The drive will no longer know the speed down to 16X.

Still slow at closing a cd though. I tred to copy a cd on the fly and worked fine.

I flashed the VPW and it works fine now - I don't have 40X cds to try the speed but at 32x is 3.55.

I am hoping Acer/BenQ fixes the next version of the firmware to close the cd quicker.

When the CD is writing the data the speed seems fine but when the data is done and the cd is closed is were all the time is going. Sometimes it seems to take 30+ seconds to close.

Like I was saying above I can write a full CD with my 24X in 4:08 this is complete.

I like the drive as it rips ok.

Woeque,

I flashed with the VOW and I'm still having the problem of the write speed options fluctuating.

Did the other firmware file solve this for you?

I'm only getting 4x and 40x. Then take disk out and get 32x. Put in another disk and get something else.

This is driving me CRAZY! :O

Thanks in advance,

J. :p

Well i tried it and now the damn thing is only writing partial disks.

The amount of data is well under but only wrote 18 out of 20 tracks. First only wrote 11 ot of 20.

I even slowed down the write speed. which, if there is no disk in will give multiple options, but only then.

This is insane. :O

Well, I updated with the VPW firmware and it sucks ! :O

I went back to the VOW.

I kept burning costers. Don't have to worry about a place to put my drink now.

I think MSI needs to do somemore testing and get us some new firmware.

Hi J,

Sorry to hear it's still not working. I just saw too that you're running WinME with a 20 GB HDD (not to mention the VIA chipset mobo :evil: ). Have you tried Nero Drivespeed or ATTO's HDtach on your HDD to see what the maximum data transfer rate you're getting from the drive is?

In one of my earlier posts I pointed to a V.QW firmware available for the drive, but I just checked and saw it's missing, which is strange. Maybe they're still in testing, so here's hoping.....

J,

Another guy who had problems with even this V.O/P-W firmware made his life easier by exchanging the drive for one by another manufacturer. Try the Mitsumi drives or the LG 40x ones.

Ok, this is the message I'm getting after running simulation.

"There is a possible read error, do you wish to continue with the burn"

or something similar to that.

Question. Could this be related to the hard drive?

If I continue, It only burns about 11 tracks of a 18-20 track cd. There is plenty of room for this(MB).

Question. Could previous firmware versions work? Could the bios be the problem? Has anyone gotten this thing to work?

Mine works a lot better after I flashed the bios to newest.

Sounds like you have either low grade cd's or hardware issues.

All dma is turned on for all drives correct?
Have you done a scan disk of your drive?
have you de-fragmented your drive?

I bought a batch of 100 Compusa cd's once and it seemed only 1 out of 8 would write correctly and this was my other cdrw TDK 24X this was happening on.

All DMA's are on, although I read on NERO site that I should run in PIO4 due to VIA chipset.

Defraged the hard drive. Should probably scandisk it though.

Using Memorex and Sony disks rated at 32x. I'm not worried about 40x right now, I just want the damn thing to write a full disk.

Also, there is no setting in my bios for DMA/PIO. AMI (3.5).

bim2k said he saw a VQ.W release for the firmware but it has dissapeared.

Think I have to start from scratch on this one.

Woo Hoo, I fixed it. I fixed it. :) :] 8) ;)

I flashed BIOS, installed new 4 in 1 drivers and left off the S.M.A.R.T. for the hard drive.

It's burning full disks, my car stereo can read them and I have full speed burning option. Although, my media is only rated for 32x, so I'm not pushing it.

Oh yeh, still using V.OW firmware also.

I really cant see how the BIOS upgrade helped, but I would recomend the new 4 in 1 and turning off S.M.A.R.T. I think that made the difference.

I don't get the "Possible read errors" anymore either.

I am all better now. :))

Good luck to all, hope this helps.

J. :p
