optical disk burning still working?

eccerr0r

Anyone burn CD/DVD's with Linux/Gentoo recently ( app-cdr/cdrtools-3.02_alpha09-r3 ) ?
Wonder if I'm just running into a bad batch of discs, bad recorder drives, or is it software bit rot?

What commandline is causing you grief? I'll be happy to try to duplicate.

Added: Just for grins, I made a quick 600+ MB CD using Brasero. I couldn't get Graveman to recognize the blank CD-R.

Been trying to erase CDRW and DVD+RW discs and they simply won't erase... it just times out and hangs or prematurely exits...

cdrecord dev=x,y,z --blank=all

I suppose I need a blank disc before I can start with the next step, actually trying to record...

I finally got graveman to work right. I had to manually add the CDRW device as /dev/sr1 because the autodetected device wouldn't recognize the media.

cdrecord is is slow, at least on my hardware, which is a TSSTcorp' 'CDDVDW SH-S223F ' 'SB03' Removable CD-ROM with 1x-4x CD-RW media.

But, so far so good. This worked OK, as root:

hmm... looks like it's working ok for you. I might even have the same TSSTcorp drive somewhere but not sure where it is at the moment...
Might have bad CDRW/DVD+RWs...

eccerr0r,

CD-R and dual layer Bluray work with Xfburn. I don,t know what it uses to move the data to the media.
I've done both over that last few days. I suspect that DVDs still work but its about 6 months since I tested.

It looks like xfburn and brasero use libburn and libisofs. graveman uses cdrtools.

And finally, "# cdrecord dev=5,0,0 blank=all" completes successfully at speed 4 with no drama.

Thanks for testing. The diagnostic output I'm getting is not clear at what the fault is (can anyone make heads or tails from the diag output?)

Do you have any associated output with dmesg?

I believe everything starts with the i/o error: "cdrecord: Input/output error. blank unit: scsi sendcmd: no error"

How does this drive do with reading existing disks and writing ordinary CD-R disks?

How about trying blanking the disk with Brasero or XFBurn which don't use CDRecord?

I've not had as many issues with write once discs most of the time. But if I'm experimenting, the cost adds up. It's these phase change/rewriteable discs that have been problematic. Was hoping that erasing would refresh the surface of these rewriteables but perhaps my expectations were too high of these discs.

Also I've gotten a lot of old/used rewriter drives that I don't know of their condition, and hoping testing with rewriteable media would reduce the number of coasters if the drive itself has issues... this too might be a fallacy.

These unserviceable DVD rewriter drives become balloon poppers if they fail writing discs...

You might try the latest (and definitely last) version of cdrecord (app-shells/schily-tools) from the mv overlay.
And in case you did not care before: Follow the recommendation of the cdrecord author to make the binary suid: Only then it can use all kernel features for improving communication with the device.

BTW are you guys using ATAPI, SATA, USB, or USB-ATAPI bridge recorders for testing?
The SH-S223F is SATA I believe, but IIRC the SOHW-1673S is also SATA. Not sure if it makes a difference...

I'm using SATA drives.

Regarding the cost of disks, about a dozen or so years ago, I had multiple opportunities to pick up from various bargain-bins large spindles of CD-R, CD-RW, DVD+RW, and even a 50 pack of double-layer DVD+RW disk. I'll never run out. My heirs will never run out. I was happy to toss a few into this experiment.

Know what, it might just be due to shelf life of these discs too... a lot of these discs are well past 10 years old and quite possibly they've simply just gone bad?
I as well have a bunch of spindles of the write-once variety, alas, it's the rewritables that seem to be problematic. Don't have as many rewriteables however.

Hi,

the error message from cdrecord means that the SCSI command A1h BLANK
failed with an error code which indicates that the command itself is
inappropriate or malformed.
A possible reason would be that the medium is not erasable, i.e. a
CD-R instead of a CD-RW.

What do you get if you insert the medium and do

Sometimes these discs don't even detect in some of my drives...
I think I have at least one of Lite-on, TSSC, HP (probably BENQ or Lite-On) and Pioneer drives. Tried the Pioneer the most recent on some of these discs and they don't even show up, seems the drive gives up when inserted. The Lite-On drive reports bad sectors when read when inserted due to udev probably searching for label information, maybe I need to temporarily stop udev from doing this (though one would expect brasero would automatically do this?)

Anyway these are definitely phase change media (gray) and have rewritable written on the label (CDRW/DVD+RW). Just that these discs seem to confuse the drive:

This looks like a bad burner or a bad reaction of the burner on a medium
with which it cannot cope.

This drive must be quite old. Nobody wants to sell some and the firmware
offers are from 2006.

What does the 'LITE-ON' 'DVDRW SOHW-1673S' (which can hardly be much
younger) tell about the medium ?
After all, cdrecord came to the attempt to blank the medium. So it must
have recognized it as something to which it can burn.

(Old burners don't necessarily have to go bad. My oldest one in service
is a LG GGW-H20L of 2008 which just survived the demise of its second
USB box.)

Another suspect would be the desktop and its possible automounting attempts.

Whatever, the combination of a medium and a drive where cdrecord cannot
report the detected medium type is not usable. Other burn software will
hardly yield better results.

At best we could learn about the sequence of SCSI commands and the replies
from the drive which get performed until cdrecord decides that nothing goes.
For that you would add option -VV to the cdrecord command and prepare for
a flood of messages:

Got one CD-R burned successfully finally, alas I forget which drive I did the successful burn in, but likely I think the 204 might be a dud drive... and have a lot of dud media (CDRW/DVD+RW)... so I guess I can safely assume the software can be ruled out of the search for which pieces are bad?

You have to blame the hardware when the proposed medium information runs of
cdrecord, cdrskin, or xorriso do not yield a plausible result. (Normally
without the super verbose SCSI log caused by -VV, -V, or -scsi_log "on",
respectively.)

The hardware consists of medium, drive, possibly SATA-USB bridge, cables,
and computer entrails from USB or SATA sockets to the CPU.
In most cases the problems sit in drive or medium, quite often in special
combinations of both. One needs to find a reliable drive and reliable
media to tell which part of the unrealiable hardware chain is to blame.

Have a nice day

Thomas
