Hi, > 954499072/25000000000 ( 3.8%) @0.2x, remaining 218:19 RBU 100.0% UBU 12.5% > WRITE@LBA=720a0h failed with SK=3h/WRITE ERROR]: Input/output error
This is a failure of the drive to write to the medium. It has nothing to do with your preparations of BDBurn.udf, but rather with the relation of drive and medium. I.e. they do not like each other (any more). The speed is very low. Possibly the drive relocated many blocks to the Spare Area. Possibibly that Spare area is now full and further bad blocks could not be replaced by spares. > CLOSE SESSION failed with SK=5h/INVALID FIELD IN CDB]: Input/output error This is not the reason of failure. But it could be a known growisofs bug, that causes an error message at the end of a burn run. Andy Polyakov, the author of growisofs, stated that it is harmless. (Some doubts have arised meanwhile, though.) > Am I creating too large of a file to burn to the media growisofs is supposed to refuse in that case. But it started writing and failed early (after only 1 GB). > I note that growisofs is saying "preformatting to 24.8 GB"? This stems from growisofs' habit to format BD-R by default. To my own experience (with libburn, not with growisofs) BD-R are more likely to fail if they are formatted. This is contrary to the theoretical advantages of formatting ("Defect Management"). > _any_ help in getting this sorted will be greatly appreciated. It might help to try writing to unformatted BD-R. growisofs option -use-the-force-luke=spare:none will prevent formatting of a blank BD-R before writing starts: growisofs -speed=1 -use-the-force-luke=spare:none \ -Z /dev/sr1=/mnt/md9/bdburn/BDBurn.udf My own programs cdrskin and xorriso do not format BD-R by default: cdrskin -v speed=1 dev=/dev/sr1 /mnt/md9/bdburn/BDBurn.udf xorriso -as cdrecord -v speed=1 dev=/dev/sr1 /mnt/md9/bdburn/BDBurn.udf --------------------------------------------------------------------- Since growisofs announced /dev/sr1: "Current Write Speed" is 2.0x4390KBps. i assume that the drive does not offer speed 1. You may inquire the list of speeds by dvd+rw-mediainfo /dev/sr1 Look for output lines like Write Speed #0: 4.0x4495=17980KB/s Speed Descriptor#0: 00/11826175 R@8.0x4495=35960KB/s W@4.0x4495=17980KB/s (this is RITEK/BR2 media on Optiarc BD RW BD-5300S) Or perform cdrskin dev=/dev/sr1 --list_speeds or xorriso -outdev /dev/sr1 -list_speeds and look at the end of their text output. --------------------------------------------------------------------- Have a nice day :) Thomas -- To UNSUBSCRIBE, email to cdwrite-requ...@other.debian.org with a subject of "unsubscribe".
