wait_cmd_sense: Input/output error

cdrwtool -d /dev/sr0 -q
using device /dev/sr0
7716KB internal buffer
setting write speed to 12x
Settings for /dev/sr0:
        Fixed packets, size 32
        Mode-2 disc

I'm going to do a quick setup of /dev/sr0. The disc is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now.
ENTER to continue.

Tried with a BD-R and CD-R

Tried with a BD-R and CD-R

cdrwtool is for CD-RW discs only.

Command failed: a1 11 00 00 00 00 00 00 00 00 00 00 - sense 05.30.06

• command a1 11 means to do fast blank operation
• sense 05.30.06 is return value of operation and means CANNOT FORMAT MEDIUM - INCOMPATIBLE MEDIUM

So error is correct there as optical drive can format/blank only rewritable CD medias.

[Gooberpatrol66]

Oh, the man page says it works on CD-Rs

[pali]

Uff, maybe some of the options could be used also for CD-R (like printing track information).

But blanking media is RW operation.

[Gooberpatrol66]

Does BD-RE work?

[pali]

BD-RE uses UDF in overwritable mode, like DVD-RAM. So formatting to UDF does not require special access to optical drive (like for CD-RW via cdrwtool) and therefore you can use any mkfs.* tool which operates directly on block device.

Unfortunately, UDF specification requires that Blu-ray must use at least UDF rev 2.50 and this UDF rev for requires for all non-recordable media to use UDF Metadata partition, which mkudffs does not support yet (issue #20).

So you can use mkudffs on BD-RE only by forcing older UDF rev 2.01, which is against UDF specification and so do not have to work with other implementations / operating systems. It works on Linux as Linux can use any UDF revision on any media type.

[Gooberpatrol66]

Is it possible to format a BD-R as UDF without using cdrwtool?

[pali]

Recordable media types are not supported directly for writing by tools which are parted of the udftools. Just mkudffs can prepare (empty) UDF disk image for recordable media type, but for writing it to media you need to use other application.

OK, thanks
