I bought some blank Memorex DVD-R to try in my new HP 840x DVD writer. I have a 4.1 GibiByte image to burn on the disk, so I tried it the simple way first:
dvdrecrd -dao -v dev=1,0,0 iso.image After writing 511 MB, dvdrecord reports a scsi error, and quits. Output is: 1st time: ------------------------------------------------------------------------------- Starting new track at sector: 2036854 Track 01: 511 of 3977 MB written (fifo 98%) [buf 92%].dvdrecord: Input/output error. write_g1: scsi sendcmd: no error CDB: 2A 00 00 23 12 7E 00 00 1F 00 status: 0x2 (CHECK CONDITION) Sense Bytes: 70 00 05 00 00 00 00 0E 00 00 00 00 21 00 00 00 Sense Key: 0x5 Illegal Request, Segment 0 Sense Code: 0x21 Qual 0x00 (logical block address out of range) Fru 0x0 Sense flags: Blk 0 (not valid) cmd finished after 0.001s timeout 200s write track data: error after 535838720 bytes Sense Bytes: 70 00 00 00 00 00 00 0E 00 00 00 00 00 00 00 00 00 00 Writing time: 116.416s Fixating...

Fixating time: 4.251s dvdrecord: fifo had 8504 puts and 8441 gets. I tried it again, with another blank, thinking it was just a bad disk. Same exact result, at the same exact place (511 MB). I dowloaded cdrecord-prodvd, tried it with yet another blank, and no problem. Cdrecord-prodvd does give some interesting warning information, though: Using generic SCSI-3/mmc-2 DVD-R/DVD-RW driver (mmc_dvd).
