Hi, > I would like to just try to burn one big file into a DVD+R DL (about > 8Gb), what command using cdrskin would you recommend ?
In general it should work on DVD with the same options as cdrecord accepts for DVD and some options known from cdrecord with CD. Well, meanwhile you found out yourself: > COMCD="-speed=$3 -v dev=2,0,0 -dao fs=1000m > ... > mkisofs $OPTS -V $1 $2|cdrskin $COMCD tsize="$SIZE"s - This should be ok. > Track 01: 4211 of 8138 MB written (fifo 100%) [buf 99%] 4.0x.cdrskin: > FATAL : SCSI error on write(2156064,16): key=3 asc=0Ch ascq=00h That's the same write error as with growisofs. Only at a different sector address. >From the specs: 3 0C 00 WRITE ERROR More is not explained by this code. The address is suspiciously near the layer break address. The error occurs at 2156064 * 2048 = 4415619072 bytes Media capacity of both layers together is reported as: > > > Free Blocks: 4173824*2KB The error spot is 69152 blocks = 140 MB _after_ the middle of this size. That is much more than any buffer delay in the drive could cause. So i can see no systematic correlation between layer break and error spot. (The layer break is what mainly distinguishes DVD+R DL from all other widely used DVD media.) To me it looks like bad media. If only Nero would be so nice to produce a misburn too ... (The cdrecord error which you reported on May 9 happens quite exactly at half image size and issues an error code 0 00 03 which is not listed in MMC-5 specs. So that error is still suspicious of systematic correlation with the layer break.) > ata3: limiting SATA link speed to 1.5 Gbps > ata3: hard resetting link > ata3: COMRESET failed (errno=-16) > ata3: reset failed, giving up > ata3.00: disabled I am not a kernel expert. Hard to say whether this documents the cause or the consequences of the write error. > Any other ideas ? cdrskin announces the size to the drive in advance if -dao is given or the size is known. With -tao or with unknown size, it would start a write run with unannounced size. (Here it deviates much from cdrecord on DVD.) So you could try this: COMCD="-speed=$3 -v dev=2,0,0 -tao fs=1000m ... mkisofs $OPTS -V $1 $2|cdrskin $COMCD - But i do not really expect that this is the decisive difference. If it works, i would suspect it to be a lucky incident, as i suspect with Nero. You may check whether my prediction is correct that the next error will happen at a different sector address or that some write runs even succeed completely. (I believe your growisofs run nearly made it.) You should verify that Nero really reproducibly can write the full media without errors. Verify whether the image file on disk is really identical to the image on media: diff /dev/sr0 disk_file If you can get different media, try them.
