this is the disc i burn recently

user posted image

its sold as Verbatim DataLife Plus 52X (SuperAzo)
the casing is different from the picture above
but the disc is exactly the same
the manufacturer is Mitsubishi Chemicals Corp.

I burn the disc with my writer (artec WRR-52X)
at 40X

C2 scan with samsung sc-152l cd-rom

C2 scan with the writer

C1/C2 scan for the same disc burn at 40X
by other ppl (from dolphine review)

QUOTED from dolphinereview
Compared to the discs burned at 48x, this is a MAJOR improvement! However we are still seeing way too many C1 errors being reported near the end of this disc, and still even a small amount of C2 errors on the low speed test, and a slightly larger amount on the highspeed scan. This does bode well for this media type however, since it means that they will likely perform better at yet slower burn speeds. I thought perhaps all the data on this disc might have been readable, despite the high number of C1 errors, and the appearance of C2 error, but when I ran scandisc on the CD, 2 files came up as unreadable... so perhaps the next test will succeed?

is the disc not suitable to be writen at 40X?
but my burner itself report no C2 errors.
its certified for 52X!
don't tell me i have to use 32X?

anybody else here use Verbatim
what's the result? is it compatible with other
readers when burn with high speed

I think I tried to burn exactly this type of CD-R, and my 24* burner determined that this disc could only be burned at a maximum of 16* speed. So there is something wrong with these discs (or at least with some of them).

But: the "Super Azo Layer" really makes them strong, I had a bad write, got angry and tried to break the disc, but it only bent and sprung back to the original shape

i did another c2 scan for
Yamaha for Disc T@2 16X (MetalAzo) i burnt last year (Dec 03)
the manufacturer is Mitsubishi Chemicals Corp.

the CD is burnt at 32X, 2 times over the rated speed, 16X

C2 scan with samsung sc-152l cd-rom

artec wrr-52x cd-writer

very confusing, this time samsung seemed to read
CD-R correctly, no C2 at the end

SuperAzo should be more "super" than MetalAzo!

but SuperAzo burnt at 40X is harder to read than MetalAzo burnt at 32X?????
I'm thinking of using MetalAzo again
but i don't see Verbatim sell MetalAzo anymore!

what?
My burner is a bit overconfident in everything

Yamaha disc T@2 certified for 16X, can be burnt at 32X

and of course, SuperAzo can be burnt at 52X

I had the same problems with Verbatim SuperAzo. I've got a Yamaha CRW3200. At 24x (max for my burner), they have C2 errors, which should never happen. I immediately stopped using them.

With a calibrated professional drive running at 1x, the maximum allowed is 220 per second averaged on 10 seconds.

The C2 error rate should be around 1 per hour or less.

can u explain why the SuperAzo i burnt
is "c2 free" when scan with my burner itself

but the reader, samsung show thousands of c2 errors at the end of the disc?

my Samsung is 3 yrs old
is it bcoz the laser is old, so it cannot read disc as
good as new

Different readers read differently. It is not uncommon to have differing results from different drives.

Jul 26 2004, 03:08

Either your burner or your reader doesn't like the cds.

Verbatim DataLife Plus gives consistently good results on the lite-on and plextor burners I've tried it with.

kotrtim

Jul 26 2004, 07:48

then,

should i keep this cd or just throw it away

as i said

my writer can read the disc flawlessly ( no c2),
samsung can read it flawlessly too (but too many C2 reported)
the read speed is also inconsistent at the end of the disc

should i keep this cd or just throw it away???

sven_Bent

Jul 26 2004, 08:25

maybe you shoudl throw away you samsung ? :-)
btw tjek if ther is a biig white sticker with a "R" on the drive.
that stand for refurbished and my experience selling theese is ...they SUCK bigtime..

They had a failure rate of above 50% in 6 months.

I'm probaly violationg the TOS #8 as i make statements about qualiyy (or the lack thereof) without ABX proffs... :-)

Jul 26 2004, 11:19

It's OK. I don't think that people returning broken drives were placebo.

Kotrtim, if this CD is the only one showing c2 errors at this absolute time of the track on your drive, then copy it on another CD that doesn't give any C2 error.

Mitsubishi Chemicals is Verbatim's parent company. The pages linked to above obviously need to be updated re: the dye types.

The C1/C2 counts will vary from drive to drive, thus the results of such test are best compared with those done on the same drive (at least the same model). The fact that different utilities will report different numbers (though the pattern should be the same) for the same disc on the same drive doesn't make it any more simple. E.g., PlexTools Pro will report more C1 errors than nero CD Speed. Furthermore, drive A may produce excellent results with media X but not Y; while the reverse may be true for drive B.

That said, I've had great results with Verbatim DataLifePlus 52X on Plextor Premium and Plextor PX-712A, though both drives like Taiyo Yuden media better. Surprisingly, burning at 16X as opposed to 52X increased the C1 counts, though not by much (~6000 and ~4000, respectively).

I'd say: ditch that Samsung and keep the CD-R. =)

The CD's sturdiness has nothing to do with the dye, of course. The extra protective layer (on the label side) probably does.

While the Verbatim/Mitsubishi disks are mechanically strong, they leave a lot to be desired in the reliability and error-free writing departments. I have had bad experiences with these disks. I once used Verbatim CDs ans Moser Baer CDs to back up the same data. After six months of use, the Moser Baer CDs showed little or no C2 errors and the Verbatims had plenty.
I guess the best thing to do is to back up files to hard drives and archive them. That's what I plan to DVD. Optical storage nowadays is too unreliable.

It doesn't seem to me that optical media are more reliable that hard drives in any way. In my case, it was exactly the opposite. I used only Mitsui Media CDRs, one of the most reliable brand with Kodak and Tayo Yuden. Nearly all of them, about 40 out of 50 , were completely dead after 4 years, from three different storage locations. They were all kept perfectly scratch free, and actually quite never used in this period, while my oldest hard drive, used about one day out of two during 5 years, is still running perfectly.
All hard drive fail. Nearly all CDR fail. Only Tayo Yuden have such a low failure rate that we can't draw any conclusion yet (exept that they are very reliable).

There is only one way the preserve digital data for years : periodical backups.

I have very very good experience with the dark dark blue dye
Its sold as Yamaha for Disc T@2

I burnt them at 32X and read them with Samsung Cd-ROM which normally never report CD-R without C2, and guess what? Samsung report no C2 at all for the dark blue ones.

I checked back the dark blue disc i burnt last year with both of my drive, and both report no C2 at all!

same here - my IBM DJNA 13GB (about 5 years old) hdd is still running and in use 16hours per day on average. Just imagine the lifespan, if it would just be a backup-hdd which is only plugged in for transfering data.

My 2 hints about increasing the lifespan of a hdd would be:
- on win32, defragment your hdd, make the swapfile being rewritten at a FIXED size (this also increases general speed of windows)
- on win32, defragment weekly BUT only defragment the files (do not do space-optimization). Defragmenting without space-optimization happens much faster(on my system on a NTFS-partition in less than a minute) so it stresses the hdd much less. Of course for this to work you need an app which supports to only defragment files without doing space-optimization. You can still do space-optimization in larger intervals(like, every 2-3 months).

To stay on-topic: i decided to switch from verbatim superazo to tayo yuden and just ordered 100 Plextor CDRs. The disadvantage is that in germany, you can get verbatims almost everywhere, but getting plextor or fuji made in japan is difficult unless you do a mail-order.

Moser Baer and CMC will use the similar dye and ATIP from MCC,
they will pay toll to Mitsubishi for dye and ATIP

They are said to have good quality control by Mitsubishi but who
can guarantee this? CMC is well known for producing worst

I tried to write another Verbatim DLP (MCC Superazo)
I write the disc at 32X instead of 40X or
the manufacturer rated 52X
this time i tried to write a self-compile 80:43 Audio CD!

the result is really good,
even the overburnt part is free from C2
when read with samsung which hates to read CD-R.

i think Verbatim is best to be burnt at 32X with my
writer and 40X with member "Sven-Bent"Lite-On liteon52327s

the 52X rated by Verbatim is obviously too high, expensive drives like
Plextor might be able handle them at this high speed,
but not all burner can do this, Verbatim should have rated their disc
32~40X

C1 Error Scans for 48x VDLP

*snip*

Lev, these numbers are not very useful without the total C1 counts and stating the program they were obtained with. But no C2s is a good start.

Don't worry, you can also get Tayo Yuden Fuji Spindles

Thank you for the info. However, i will probably stay with plextor - more easy than all the hassle to identify other brands as TY. For the extra-ease i'm willing to pay a few euro more.

Yeah, like any info, about anything in the computer world would still be valid two years later. Let alone something as volatile as OEM branding of optical media.

You can, however, buy TY media here: www.rima.com

CDR-Writer: AOpen CRW5232 (2 months old, so its brandnew)
Write-Speed: 32x
Burn-App: Burnatonce 0.99.5

All 3 CDRs were written using the same data & settings. My drive does not support C1-error reporting. The CDRs were scanned with CDSpeed immediatelly after burning.

My first Plextor-CDR (Tayo Yuden):

Okay, maybe i just had bad luck, so lets try another one - notice the higher scale:

No thanks to tayo yuden for me. So i went into a shop and bought a spindle of Verbatim DatalifePlus SuperAzo's:

I will return my mailordered Plextor-CDRs and ask them to give me my money back.

Did you try scanning them at lower speed yet ?

It's no secret that different drive manufacturers produce drives that work better with one media type, or another. If AOpen doesn't have good results with TY, then you're doing exactly the right thing...

As soon as i go below 12x scanspeed, the errors disappear - however, the speed really goes down below 1x at the places where the C2 errors are displayed when scanned at higher speeds.

I sometimes do experience this behaviour, too ... there seem to be some drives (including my LiteOn 52246S CDRW) that have problems reading parts of TY discs at higher speeds - might be a problem of low reflexivity or jitter peaks.

It would be interesting to see how these test discs of yours perform with plextools q-check feature ...

Bad results with Taiyo Yuden media are a pretty good indication there is something amiss with the burner's firmware.

Have a look at the test archive at CD Freaks - out of some 50+ entries there are only two entries reporting C2 errors (not counting rdgrimes' buggy drive that will always report 100 C2 in the middle of the disc). Of those, one is put down to the drive's fault by the author. Rather conclusive evidence.

Besides, you cannot see the C1 counts on those Verbatims - and those are typically several times those of the Taiyos.

Still, Verbatim DLP is pretty decent media if you don't push it too hard. Despite being "52x drive approved" it craps out at 52x on both of my Plextors, but results at lower speeds are encouraging. When I'm done with my tests, expect to see some new entries at the above-mentioned archive.

Well, I guess you are stuck with Verbatims then.
