i changed the write speed from 18x to MAX, and it appears to have worked… kinda…

first burn on MAX, the drive spooled up very quickly (and sounded about twice as loud,) but as soon as it started to write, the burn nearly instantly failed.

second burn on MAX, same as above, but instead of failing instantly it started to write! very fast, with the speed rapidly increasing! shortly though, around 10%, the rate dropped to 0x for a moment, then increased to 6x for the remainder of the burn.

:frowning:

disable smartburn

disabled SmartBurn… burn maxing out at 8x now with MAX selected.

reset the SmartBurn setting to default (enabled,) so the configuration was the same as in post #2, but the result was different… the same as in the first post and the last post, MAX selected; burn still tops out at 8x.

try clearing opc, and check all 4 checkboxes. do a test burn in cd-dvd speed and post the burn graph.
are the dvd and hd connected to the same ide channel?

cleared the OPC history before the last test i did.

Online HyperTuning would defeat the purpose of overspeeding, and Forced HyperTuning & OverSpeed are the only two required options to overspeed according to Lite-On, so that would be irrelevant anyways.

i have scanned each burn that didn’t fail (the ones that maxed out 8x, and the one that started burning really fast, dropped, then maxed out at 6x,) and they were all fine. no PIE spikes over 10, no PIF spikes over 2.

writer is on a separate IDE channel, and i have no speed issues writing DVDs normally.

here is a log of a DVD i just burned with everything defaulted (unselected) in SmartBurn. there is nothing wrong with my hardware configuration (note average & max write and verify rates,) or the drive when burning normally.

what on earth gave you that idea.

SONY16D1 and SONYD21 seem to only be easily oversped when made in Japan. Every batch of MI Taiwan I’ve had has [B]maybe[/B] had only one disc successfully overspeed to 18x. 16D1 made in Japan was able to be written at 18x and 20x readily.

Trying to burn a D21 MIT right now, actually. The drive chose to write at 16x, but I have had it fall back to 8x and 6x with 18x selected. The only thing I have forced is OHT.

[Overspeeding and OHT with this media MIT does seem to cause the drive to take longer, with it spinning all the way down & back up during a relink. But with the proper quality of these disc, OHT actually HELPED my drive burn at 20x faster than it could have, otherwise, & with quality of 16x and slower burns.]

[BTW, the burn took 6:45 due to Smartburn falling back to 16x during the leadin, longer than some 12x burns.]

OHT doesn’t work at 20x. or maybe it does in ll0c, but it didn’t in previous firmwares. I’m out of 20x capable media to test.

With 16D1, it did. Otherwise, the PIE and PIF began to stack up, and neither of my drives could scan it before throwing an error at me.

It also threw one of my 20x burns back to 18x and managed to finish successfully.

(Maybe my drive is just weird, 'cause it just forced HyperTuning for another of my burns, and allowed HT/OHT for TYG03 20x and 18x burns.)

hmm maybe it’s ll0c. the last time I tried 20x was ll0b.

edit: you’re right, it does. score 1 for local radio shack

20x OS
OS/HT/OHT enabled




20x overspeed
OS/HT enanbled, OHT disabled




@ seeker

I’m not sure if those burns make me want to overspeed anything other than TY media anymore…

At least it let you overspeed the first time w/OHT and fell back when it couldn’t relink (although it would have done well to fall back again]. The second time, as always, the drive fell back to an 6x speed. But it was successful.

[off-topic] Are those TDK good for burning at their rated speed? [/off-topic]

From my experience, i do not suggest burning media like CMC MAG M01, RICOHJPN R03, TDK 003 and MCC 004 (these DVDs are sold in my local store, so i couldnt test others like TayoYuden) at more than 16x speed.
The results of burning it at 18x can be

  1. High chance that lead-in will take up to 2 minutes
  2. Low chance that writing at 18x, burning will take 2x more time
  3. Medium chance for the burn process to fail
  4. Medium chance that burned media will have lots of errors
  5. Low chance that media will burn with excellent quality

Although writing at 16x, burn quality of these DVDs is excellent and takes 5:40 to 6:00 minutes to burn (lead-in ~40 seconds)

Highly agree with that. Only get media that the firmware has a default 18x strat for, and even then, stick with MCC, TY, MIJ SONY, and MAYBE really good Maxell and MBI MIDs*. [Each MID should be found under the respective brand, and Sony & Verbatim/Mitsubishi use TY from time to time. I don’t remember the good brands for higher quality MBI right now, except for MBI-made MCC codes.]

*note that I probably left a really good 18x media out, but that’s all that I’ve seen so far. Most of those can also do 20x with the super-good batches. [Some good TDK TTH02 DVD-R can overspeed to 18x, but it has to be a really good batch. The first disc of my batch kinda messed up in the last .5 GB of the disc at 18x, but I blame that on a bad relink.]
