Re: DVD: can't burn dual layer or at 4x
Can't find my original thread re: this problem, but this is close. I was having all sorts of errors trying to burn 8x media @ 8x. The burn would be physically bad, with blank bands, scorches, etc. Below that, they were fine, and 16x media worked @ 16x. I thought I'd tried everything, different media, burners, boxes, even distros. I noticed my BIOS would complain at boot that the IDE cable for the burner was only 40-wire. Since I had almost none of this trouble on the windows side (except 16x media @ 16x speed), I disregarded it. But lo and behold, when I switched to an 80-wire cable, all the problems seem to have vanished. I'm 3 for 3 in error-free burns at intended speeds thus far. -- http://www.livejournal.com/users/darkaudit/ pgp5tu36aBhRw.pgp Description: PGP signature

IIRC the post you're replying to was mine, and later I answered that I had solved the problem by upgrading to the latest dvd+rw-tools and k3b. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Anyway, if I am not mistaken remembering what Jens Axboe said, you should use dev=/dev/dvd instead of dev=ATAPI:/dev/dvd to access your drive. This is the way that I've been using to burn CDs and is working fine with my (very old) CD burner with my custom built kernel (2.6.10-rc3). Hope this helps, Rogério. -- Learn to quote e-mails decently at: http://pub.tsn.dk/how-to-quote.php http://learn.to/quote http://www.xs4all.nl/~sbpoley/toppost.htm -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

DVD: can't burn dual layer or at 4x
I have an NEC ND-3500AG DVD burner. The mfr specs say it can burn single layer DVDs (-R, +R) at 16x, and dual layer DVDs at 4x. But so far I can't get any burn speed above 4x, and I can't burn dual layer at all. I mainly use K3b for burning, but have fooled around a bit with cdrecord and growisofs. None of these have anything to say about DL DVDs, and growisofs complains if I try to burn an 8 GB ISO. It has an overburn option but this doesn't seem well suited to dual layer. (Though I admit I haven't tried, since dual layer media cost about $5-$7 each.) As for the slow single layer burning speed, cdrecord provides some information: $ cdrecord dev=ATAPI:/dev/dvd -prcap snip Warning: Using ATA Packet interface. Warning: The related Linux kernel interface code seems to be unmaintained. Warning: There is absolutely NO DMA, operations thus are slow. Using libscg version 'schily-0.8'. Device type: Removable CD-ROM Version: 0 Response Format: 2 Capabilities : Vendor_info: '_NEC' Identifikation : 'DVD_RW ND-3500AG' Revision : '2.16' Device seems to be: Generic mmc2 DVD-R/DVD-RW. Drive capabilities, per MMC-3 page 2A: snip Maximum read speed: 8467 kB/s (CD 48x, DVD 6x) Current read speed: 5645 kB/s (CD 32x, DVD 4x) Maximum write speed: 8467 kB/s (CD 48x, DVD 6x) Current write speed: 1411 kB/s (CD 8x, DVD 1x) Rotational control selected: CLV/PCAV Buffer size in KB: 2048 Copy management revision supported: 1 Number of supported write speeds: 6 Write speed # 0: 8467 kB/s CLV/PCAV (CD 48x, DVD 6x) Write speed # 1: 7056 kB/s CLV/PCAV (CD 40x, DVD 5x) Write speed # 2: 5645 kB/s CLV/PCAV (CD 32x, DVD 4x) Write speed # 3: 4234 kB/s CLV/PCAV (CD 24x, DVD 3x) Write speed # 4: 2822 kB/s CLV/PCAV (CD 16x, DVD 2x) Write speed # 5: 1411 kB/s CLV/PCAV (CD 8x, DVD 1x) So clearly cdrecord, at least, isn't seeing all of the capability that my drive is supposed to have. But even it thinks I can burn at 6x, while in fact I never get more than 4x, even with 8x-capable media. Questions: (1) Is the burn speed restriction a limitation of the current ATA implementation (libata?)? Related to the no DMA warning? (2) Are people getting better than 4x burn speeds? With what burner? I'd love to hear from someone with an ND-3500AG. (3) Has anyone out there successfully burned dual layer DVDs? How? With what burner? (4) How can I get more information about the medium that's loaded in my drive? E.g. max burn speed, whether it's dual layer. BTW, I'm using all DVD+R; haven't tried -R yet. Thanks in advance for any light you can shed on this. Andrew. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
