Problem with 1620 or Media?

#1

Hi all,

I am new here and just recently bought a BenQ 1620 and updated the f/w to B7P9.

Using CD-DVD Speed (v. 3.6.1) I burned a data disk from a Yuden DVD+R 8x. After reading numerous posts and quality tests of others it sounds like PI Failures are acceptable up to ~15. But, the Yuden I burned tested at over 21.

Anyone have any thoughts?

Many thanks,
Lance

Your TY could be a fake Yuden, as others have reported before, or it could just be a bad one (sometimes the first one in a spindle is damaged, although this is unusual with real TY’s). (BTW Most scans are made at 8x, so you could try that to see if makes any difference.)

I think its a bad scan not a bad disc. My drive shows VERY high PIE and PIO errors when the read speed goes above 14x which is about 3.5Gb, it seems to rise exponentialy and produce the ramp effect you see there.

Try your scan again at 8x and I think youll see the bad end of the disc will not be there

Burning at 16x speed is fast, really fast, and not all drive can keep up at this speed even when using quality media like Taiyo Yuden.

Mine NEC´s 3500 burn these discs without a hick all the way to 16x. BenQ for some reason has a little problem when past 14x speed. And this not only on Taiyo Yuden but also on other high speed quality DVD+R (plus) media… :confused:
I have tried the latest firmware but with no avail.

Scanning at 8x speed (with Nero CD/DVD Speed) seem to be the norm here in BenQ/Philips forum. Although when scanning a burned DVD-ROM, the speed is the same when set to 8x or at “maximum”.
qwakrz, there are no “bad scans”. The drive is only reporting what it is reading…
Transfer rate test and a disc scan is recommended when the drive reports a lot (high) errors and failures.

Finnally, here are mine experiances when burning same media. (Rescanned today.)
MID: YUDEN000-T02
Brand: Taiyo Yuden
Disc: DVD+R 8x rated
Burned at 16x
Burned as: create data disc
Burntime: 6:12

Thanks for the all of your responses.

Xterminator - I bought the disc from RIMA, so my guess is that it is a genuine Yuden.

Nero Info tool reported that my System ASPI was “Corrupt” so I uninstalled it and re-flashed the f/w. Not sure if this contributed to the improved burns or not.

I also did two other burns: Yuden @ 8X and TDK/Ricoh at 8X and got the following (better) results:

Some have had bad results when scanning at 16x (maximum) try scanning with Nero at 8x on that TY02 disk and see what you get.


#7

EagleClaw - I scanned the TY02 at 8x and curiously got more PI Failures:

Tell me about it. Sometimes I really wonder about error scanning and its validity. Thanks for posting the 8x scan though. :slight_smile:

Socrates - I guess I’m wondering now why my 1620 is getting higher failure rates than others using similar media.

Is this something I should worry about (i.e., consider exchanging the drive for a new one) or be content with lesser quality (per Nero) burns?

Thanks for your opinion,
Lance

I don’t think you’ve done enough testing to know for sure. I would test different firmwares, different media (even the same media but from different spindles), different IDE cable (a good flat 80 wire one), master/slave configuration and different IDE channels, and even different systems if possible. If I still got less than good quality scores when scanning, then maybe I would consider exchanging the drive for a new one. Do you defrag your hard disk regularly? Do you have most background programs and processes turned off when burning and scanning, etc.?


#11

Socrates - Thanks for the advice.

I will try updating the firmware to B7T9 (is it official?) and try burning a couple of more TY02s. I’ll report the results.

I am using the IDE cable that came bundled with the drive and I’m not sure if it’s 40 or 80.

I do defrag religiously and make sure all other apps and processes are kept to a minimum.

Here’s an Info Tool report. Does anything look wrong?

After re-flashing B7P9 (still haven’t tried B7T9), I ran a two more burns using TY02 media. Here are the test results:

Wow I wish I had as good results as you for the TY02’s. Here’s my scans.
