708a & Verbatim 4x dvd+r AHHHH!:eek:

Hello Everyone,

  I just got a 708a and bunch of Verbatim 4x dvd+rs with manufacture code MCC 002.  Can someone please tell me if this media really burns at 8x?  I've seen it in posts that this is possible, but when I ran a Nero DVD speed test (version 6.3.0.2)and burned some dvds, it averaged 4x :(  I have the latest firmware, 1.04, and it's running on UDMA mode 2.  My test came out something like this:

General Information

Operating System Windows XP Professional
Drive PLEXTOR DVDR PX-708A
Firmware Version 1.04
Serial Number 110945
Disc DVD+R
Capacity 4.38 GB

Write Transfer Rate

Write Mode DAO
Start 6.04x
End 6.04x
Average 4.33x
Type CLV

Log

Time Elapsed Action
[06:40:22] Creating Data Disc
[06:54:12] 13:52 Speed:6 X CLV (4.33 X average)

As you can see the test says it's done around 7 minutes, but the disk is only about 55% completed, that's where the timer keeps running and 13.52 is my end result. I really don't know what to do if these disks are capable of being burned at 8x! Any help would be greatly appreciated, thanks everyone :bow:

P.S. Sorry for this post if it's not the best, I'm a total newb to forums.

If your doing a transfer rate test, it could be something else other than media. It’s starting out at 6x, which is what it should for Verb 4x media. looks like it ran out at 4x.

Use the Create Data Disc from the tests menu to graph the actual write response. Should start at 6x, jump to 8x about 700MB into the burn, then continue at 8x all the way to the end. If it drops to 6x or 4x before the end of the burn, the media is marginal for high quality. You lose a CD but gain a benchmark.

Hi Bob,

 Thanks for the reply :) The results I posted were actually from a "Create Data Disc" test.  So basically I just got shafted on these disks because they have been known to be burned at 8x?  Does that mean that there is no gaurantee as to whether or not most +r 4x media will burn at true 8x, even if Nero and DVDinfoPro says it's capable, it just depends on the particular spool?  That would be real dookie :confused: If this media has been burned at 8x, does anyone happen to know the media code and is the media code the same for each disk in a spool?  Hmm really wish things weren't this complicated, I just want an 8 min dvd burn VS a 14 min one!  As always, your responses are always welcome and appreciated, thanks.

I read from I think the Plextor’s web site, is that media quality can vary EVEN fom the SAME spool.


#5

Start 6.04x
End 6.04x
Average 4.33x
Type CLV
This is strange… it starts at 6x and ends at 6x but still the average speed is 4x. Could you post the graph here setorock? You can attach the image when you reply.


#6

Hey G@M3FR3@K,

 I saved my results as an http file because I thought it would be easier to post it in this message board.  Unfortunately...... I guess it didn't save the picture, or I just don't know how to view it :Z Is there a way to get this graph without having to burn another dvd+r?  Oh and do you agree with what was previously mentioned concerning the quality within a spool varying?  I think it's so bad for someone to buy some media and not be gauranteed a certain performance, but I guess I can't be too disappointed because they at least do what they say they will and burn at 4x :a Hope to hear from you soon!

#7

There is no other way to get the graph other than to waste another DVDR disc unfortunately. And I agree with what has been said: quality may vary, even if the discs are from the same spindle. I personally use DVD-R discs mostly since 4x recording is fast enough for me. I’m currently using Samsung DVD-R 4x discs made by BeAll. They work excellent so far in the 708A drive.

with google and read the date backwards so I thought it was from a few days ago (its from the beginning of the year)

but…
I am having the same problem, from my other post:

I have burned like 20 disks at 4x with no problems.

But, while it says its buring at 8x, it only burns at 4x (it is taking twice the time it should at 8x)

I have only tried this with one disk so far. Its a data disk of ISOs with like eight ~500MB files and a few txt files.

Anyone else notice this? [/B]

Burned a data DVD using a Memorex 4x DataLifePlus DVD+R (MCC 002) @ 8x with a LDW-851S. Used a “hacked” GS0A firmware and Nero 6.3.0.2. DVD+R burned in about 8:28 minutes.

Verification failed. DVD+R ended up being unreadable. :frowning:
Noticed that the dye looked foggy after the burn at a section of the DVD+R. Had no problem burning at 4x.

Can successfully burn a RICOHJPNR01 (Memorex 4X DVD+R) at 8X with no error.

Hi Super Mod G@M3FR3@K =)

Thank you for always replying, your of great help!  I'm going to try and get a create data disc graph up here as soon as possible.  Hopefully it'll turn out just like my past one and not burn at 8x!  Funny I'm actually wishing it to be a bum disk:eek: Can you tell me how beneficial this graph will be in helping me solve this problem with the media?  Well talk to you laters.

P.S. OpaOPa, try to do these tests too and post your results because with 2 of us working on the same problem things might get figured out faster :wink:

Hi Guys,

 Thanks OpaOpa for the info, don't know what it means though :p  Maybe someone can lend us their expertise?  Here is the graph G@M3FR3@K from my most recent "create data disc" test.  Hope it helps and give me all of your input!  [img]http://www.teamoreo.com/files/nerotest.png[/img]

#13

hey, does running that test waste a disk, or can I test a burn of files so that I end up with a useful DVD?

(I could try and find the answer, but I am lazy, um, I mean efficient, so I ask you)


#14

Oh yah does it waste a disk :frowning: but oh well I just hope it provides useful information to someone out there who can help. Good luck to you OpaOpa if you are trying to figure stuff out as well and keep those responses coming!


#15

its worth it to me – I’ll use a disk – but not till this weekend


#16

What kind I Atapi Cable r u using??? the one that came with the drive??? Try a different cable, which input are u using the middle or the end??? If your using the Round type try the flat type. I have heard of some problems with the round type, but they do look cool.


#17

setorock, thanks for the graph since now I understand your results. The weird thing about Nero CD/DVD Speed is that it reports the end speed as the highest measured speed instead of the speed at the end of the burn process. That’s why I was confused… I thought the drive started burning at 6x, decreased the speed and then increased it again which is something that the Plextor PX-708A normally doesn’t do.

Anyway, the graph you get a quite normal for a disc the Plextor ‘thinks’ it can burn at 8x but actually can’t. All I can suggest is to try some other media that works at 8x. Even though the media you’re currently using can work at 8x, there is no guarantee it actually does! For a list of media that works at 8x you can check here and here.

That’s all I can do for you unfortunately…


#18

This is normal for a lot of different discs.

The plextor always checks quality while writing and if it detects problems it slows the speed down to 4x. This may happen as early as at the point where it should shift to 8x (as shown here).

So it’s all about the media.

MCC 002 is varying greatly in quality, depending on the manufacturer. Look at the package:

Made in India: Made by Moser Baer.
Made in Taiwan: Made by CMC Magnetics.
Made in Singapore: Made by Mitsubishi themself.

Made in Japan: Made by Taiyo Yuden, these also have Taiyo Yuden media code: YUDEN000T01


#19

SIGH

 Well I appreciate all of your help, especially G@M3FR3@K and OC-FREAK, thanks for the input.  I guess I'll just have to try different brands of media and keep the "hit or miss" mentality.  I have another quick question for OC-FREAK.  You mention that the disc's quality varies depending on manufacturer.  Can you tell me which ones are the best of the group?  All of mine are made in Singapore making them Mitsubishi Chemical discs.  Again I thank you all for your constant help and support.  Until next time...hopefully the last time :p

#20

It varies greatly.

MCC 002 from Singapore have been ok for me, but MCC 003 from Singapore sucks. So it may be just production batches differences.

MCC 002 from Taiwan is not so good.

MCC 002 from India is good except the last 5-10% of the disc, which in the worst case may be completely unreadable after written.
