Media Compatibility With CD-RW Drives - Which Media Is Best?

by **dodecahedron** on Tue Jul 01, 2003 9:41 am

this raises an interesting questions.

up till now the criteria for this topic was 100% green in CD Speed ScanDisc.
would'nt 0 Errors in CD Speed Quality Check be an equivalent (or maybe somewhat more strict) test, and also it's CDSpeed so it's universal for all drives (that report c2 errors) ?

by **dolphinius_rex** on Tue Jul 01, 2003 4:04 pm

Yeah, I've wondered about what drives were used for the testing too, if the drive doesn't support at LEAST 95% C2 accuracy, it's kinda not worth it in my opinion.

It's OK, actually, this isn't the first exception I have made. You make a good point about using the same to scan the disc that was used to burn the disc. There are a couple results in the list that were checked with CD Doctor on the same drive that burned the discs. I hesitate to go nuts with adding CD Doctor or even CD Speed Quality Test results because what is the cut-off point for C1 errors? Any C2 = no good, but too many C1 also = no good. With CD Speed ScanDisc, the results are plain to see, even to the novice: red, yellow, or green. There is no messing with numbers.

by **dolphinius_rex** on Tue Jul 01, 2003 6:34 pm

The problem is CD Speed has been known to miss C2 errors, because it slows down to read the disc when there are problems. I've had some pretty bad discs (not unreadable mind you) pass through with all greens. This is why I prefer more professional software like K-Probe or CD Doctor, since they attempt to keep the read speed specified.

is kprobe and cd doctor free software becuase i will download them.

They're free. But they probably won't work with your drive. KProbe works with LiteOn's only: for checking CDR(W)s use a burner, not a DVD. CD Doctor works with LiteOn's and some Sanyo drives.

So I guess you're out of luck with your LG.

if there is any software that works with my LG drive please tell me

by **dolphinius_rex** on Thu Jul 03, 2003 12:27 am

Nero CD speed, it ins't as advamced, but it is MUCH better then nothing

by **TheWizard** on Thu Jul 03, 2003 12:55 am

Ah yes, thank you for reminding me, dolphinius_rex.

Another reason why I chose Nero ScanDisc was because it could be used with any drive that supports C1/C2 reading. KProbe, CD Doctor, etc. can only be used with certain drives manufactured by a select group of companies. Yet another reason was because at the time I started this list, the only other known C1/C2 software was WSES, and that was not easy to get a hold of. This is not to take anything away from WSES/CD Doctor or KProbe, mind you.

by **dolphinius_rex** on Thu Jul 03, 2003 2:52 am

The real problem I see is that if the drive doesn't support very high C2 accuracy, then the test results people bring forth are completely meaningless.

by **TheWizard** on Thu Jul 03, 2003 4:20 am

Blame the drive and its manufacturer.

As was stated when I first started this list, these results are by no means set in stone. All they offer is a guideline, they are not the be all and end all of media compatibility.

It's even worse- there are drives (like the newest Mitsumi) that don't flag C2's at all. CD Speed is SOL on that one. Apart from these problems, though, I think that CD-Speed surface scan or quality check offer a good criterion. It certainly opened my eyes when I scanned some of the disks from my old burner :evil:

after getting the LiteOn.

No real surprises on the following. I was hoping for TY (like InstantInfo said), but I guess these are mostly Ritek in Europe now.

Code: Select all: LiteOn LTR 48246S Firmware SS0B...........Maxell/RTK 80min 48X....................48X

KProbe: C1 max/ave: 20/0.73, CD-Speed: all green (after I wiped some finger prints off). Since I'm doing the tests myself and not just pointing you at Ian's results, I used surface scan.

At first I got some errors (on quality check too) but a close look showed some finger prints (I was trying to read the engraved nos. on the disc

).
ATIP from MInfo:

Code: Select all: Disc Type = CDR (A-) Lead In = 97:15:17 Lead Out = 79:59:70 Nominal = 702.82MB (79m 59s 70f/LBA:359845) Manufacturer = RiTEK Corporation Cur. Speed = Wrt(48X),Rd(48X)

Smartburn calls this "RiTEK JS-dye", same as the TDK 40x (which are better). Is this just the last digit in the Lead-In being decoded?

this is what my LG 8520B Firmware 1.04, detected as optimal speeds

Imation 48x = 40x

TDK 48x = 52x
manufactured by Ritek
DataStream 48x = 48x

I will have to test some more cds soon, the ones in green have just been tested.

I enabled the display of real time speed in Nero. Apparently, even though I selected 52X, the disc reached only 39.8X at the end, with 699 MB of data, burnt in DAO.

And thanks cfitz, you saved me from a potentially ugly situation!

Thanks gents.

bhairavp: How did those discs look in Nero/CD Speed ScanDisc?

by **gregpmr** on Wed Jul 16, 2003 6:01 am

How about something on why TDK CD-RW80HS disks are not burnable with my NEW Iomega Predator. It's big, fast, noisy AND fussy . Why? :evil:

Hi Wizard. All green sectors. I think the Lite-On really likes this media!
Now only thing is, I don't know the longevity of these discs.

TheWizard: how do we take a speed reduction like this into account in your compilation? It didn't really burn @52x, but 40x. cfitz noted this on one of my previous contributions, and I pooh-poohed the remark at the time, but maybe we should take this more seriously ?

(Incidentally- I've had pretty good results with MBI too.)

by **TheWizard** on Thu Jul 17, 2003 2:28 am

I go by the speed selected by the user before the burning process actually starts. If the drive cannot actually reach the maximum speed, oh well. :-?

by **Burn2death** on Sun Jul 20, 2003 4:41 am

LG 8481B O/C to LG

Generic Rated@48x

ATIP: 97m 26s 11f
Disc Manufacturer: Postech Corp
Recording Layer: Dye(Long strategy;e.g. Cyanine,Azo etc)

Max burn speed 32x
Actual burn speed is only24x, and some times it's only able to burn @16x.
about 9 out of 10 CDs burn @24x is 100% green with ScanDisk, so I would say that it's safe at the max speed of 24x.
according to Liteon 52246s it's only able to burn @ 24x also, What Crap! stay far away from these cheap shit. :evil:

by **faithfoo** on Sun Jul 20, 2003 5:22 am

right to say that the best CDRW media is Verbatim( Mitsubushi)

( If I cannot get hold of TY )

the best CDRW drive is probably Lite on ??

by **aviationwiz** on Sun Jul 20, 2003 9:29 am

No doubght that Mitsubishi Media is top quality. As far as the best writer, I am going to disagree with you there. Plextor!

by **TheWizard** on Mon Jul 21, 2003 12:51 am

Thanks Burn2death.

Although I usually don't mind if this thread gets off topic at times, please do not start a debate of which drive is the best here. Do that in another thread, or better yet, don't do it at all. It always ends up in useless arguing. Best is a matter of opinion, we'll leave it at that.
