From reports I got for Cdrecord-ProDVD, cdrecord does not need an update
for the Sony drive, it just works

 Which one(s) do you like/use and why?

I use gtoaster when making audio CDs. Haven't found a need to use a GUI
otherwise. gtoaster is the first one I found which burns audio from mp3s. I
don't think it's a particularly good GUI, but it does make it possible
to pick and arrange songs as I wish.

 Not when it comes to burning DVD+RW/+R media. cdrecord-ProDVD works only
 with DVD-RW/-R media. A.
 
 But DVD-* media is cheaper and I see no advantage in using DVD+ media.

I didn't post the announcement to be dragged into this discussion so I'm
not going the comment on this. Cheers. A.

 Hi all:

 This is a wish.  Why the burnfree option is disabled by default?.
 Why is not enabled by default?

 Bye.

Because it increases the chance of bad CDs. No, I don't know how or=20
why either, but that's what J=F6rg says, and there's no arguing=20
against that.

Right, depending on the writer it may create CDs that are not readable 
anywhere.

Re: Problems with readcd and Aopen CDROM drive

2002-11-04 Thread Joerg Schilling
From: [EMAIL PROTECTED] (Tom Crane)

Dear All,
   I have the following problem with readcd: Using the command,

$ readcd  -vv dev=0,0,0 -f /tmp/test2.raw
scsidev: '0,0,0'
scsibus: 0 target: 0 lun: 0
Linux sg driver version: 3.1.24
readcd: Warning: controller returns wrong size for CD capabilities page.
readcd: Warning: controller returns wrong size for CD capabilities page.
Capacity: 181489 Blocks = 416857 kBytes = 407 MBytes = 426 prMB
Sectorsize: 2352 Bytes
Copy from SCSI (0,0,0) disk to file '/tmp/test2.raw'
end:181489
addr:   181489 cnt: 411
Time total: 593.027sec
Read 416857.55 kB at 702.9 kB/sec.

generates the file,
-rw-r--r--   1 root users426862128 Oct 30 20:10 test2.raw

However, the image is corrupt. The source CD (actually a CDR) is OK and
repeated applications of readcd give the same written image. However, using dd
to dump the source CD completes without error and gives,
-rw-r--r--   1 root root 371689472 Oct 30 19:51 test.raw

Reading your report again gives the following results:

-   Your CD drive returns an invalid sector size of 2352 bytes.

-   As Linux does not support DMA residual counts in the kernel, readcd 
cannot detect the problem and is most likely writing a file that
is made of many chunks with the following layout:

| n * 2048 bytes of data|  -  n * (2352 - 2048) bytes of nulls |

One advantage I find is the ability to burn directly from NFS mounted
partitions. It's slow but it works well. I've got gobs and gobs of data
spread across many machines, many filled to capacity. It takes me less
time and a lot less work to cross mount our aging workstations and burn
directly than it does to copy and create iso files, and then burn. 

Other advantages are the ability to completely fill the disks ( 4 GB
iso files are a problem on 32 bit systems) and not needing free space
for the disk images.

Although its possible to pipe mkisofs output to cdrecord and avoid
producing an image, (which I usually do for CDR), buffer underruns
are a problem when the files live across on a NFS partition.

Of course, YMMV.
