Hi,
more mail will follow. This one is only about the outcome of the proposed
cd-paranoia tests.
The results look good (with my two changes for "Table of contents" and
"Attempting to determine drive endianness from data").
The long run time of "cd-paranoia -Q" with my track 1-3 CD turned out
to be caused by poorly readable or unreadable sectors on the CD.
-------------------------------------------------------------------------

> cd-paranoia -B
$ cd-paranoia -v -d /dev/sr4 -B
...
Data appears to be coming back Little Endian.
certainty: 100%

Table of contents (audio tracks only):

===========================================================

6. 2682 [00:35.57] 5364 [01:11.39] no no 2
TOTAL 8046 [01:47.21] (audio only)

Done.
$ ls -l

-rw-r--r-- 1 ... ... 6308108 Dec 12 10:08 track06.cdda.wav
The file sizes match the track: (file_bytes - 44) / 2352 = track_size.
44 bytes is the WAV header.
$ file track*.cdda.wav
track04.cdda.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16

track06.cdda.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16

-------------------------------------------------------------------------
The same with the CD that has track 1 to 3:
$ cd-paranoia -v -d /dev/sr4 -B
...
gnawing again on:
Attempting to determine drive endianness from data....
and then
010: Unable to access sector 2682: skipping...
...
outputting to track01.cdda.wav
INFO: ioctl CDROM_SEND_PACKET for command READ CD (0xbe) failed:
Input/output error
...
Medium and drive are not in love. I abort.
-------------------------------------------------------------------------
Another CD with track 1 to 3 (this one shows quick determination of
endianness):
$ cd-paranoia -v -d /dev/sr4 -B
...
1. 3290 [00:43.65] 0 [00:00.00] no no 2
2. 3061 [00:40.61] 3290 [00:43.65] no no 2
3. 1293 [00:17.18] 6351 [01:24.51] no no 2
TOTAL 7644 [01:41.69] (audio only)
...
Ripping from sector 0 (track 1 [0:00.00])
to sector 7643 (track 3 [0:17.17])
outputting to track01.cdda.wav
(== PROGRESS == [ | 003289 00 ] == :^D * ==)
outputting to track02.cdda.wav
(== PROGRESS == [ | 006350 00 ] == :^D * ==)
outputting to track03.cdda.wav
(== PROGRESS == [ | 007643 00 ] == :^D * ==)
Done.
$ ls -l track0[123]*
-rw-r--r-- 1 ... ... 7738124 Dec 12 10:29 track01.cdda.wav
-rw-r--r-- 1 ... ... 7199516 Dec 12 10:29 track02.cdda.wav
-rw-r--r-- 1 ... ... 3041180 Dec 12 10:29 track03.cdda.wav
The file sizes match the track sizes.
$ file track0[123]*
track01.cdda.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16
bit, stereo 44100 Hz
track02.cdda.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16
bit, stereo 44100 Hz
track03.cdda.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16
bit, stereo 44100 Hz
So at least the track range is handled properly.
-------------------------------------------------------------------------
> 2) Rip a span of a CD:
> cd-paranoia 6-8
Again with the CD that has track 4 to 6:
$ rm track*
$ cd-paranoia -v -d /dev/sr4 4-6
...
Ripping from sector 0 (track 4 [0:00.00])
to sector 8045 (track 6 [0:35.56])
...
outputting to cdda.wav
(== PROGRESS == [ | 008045 00 ] == :^D * ==)
Done.
$ ls -l
-rw-r--r-- 1 ... ... 18924236 Dec 12 10:44 cdda.wav
The size matches the total size from start of CD to start of lead-out.
-------------------------------------------------------------------------
With the nicely readable CD that has track 1 to 3:
$ rm cdda.wav
$ cd-paranoia -v -d /dev/sr4 1-3
...
Ripping from sector 0 (track 1 [0:00.00])
to sector 7643 (track 3 [0:17.17])
outputting to cdda.wav
(== PROGRESS == [ | 007643 00 ] == :^D * ==)
Done.
$ ls -l
-rw-r--r-- 1 ... ... 17978732 Dec 12 10:53 cdda.wav
File size and CD size match.
-------------------------------------------------------------------------
Trying to read the bad CD with cdrskin:
$ cdrskin -v dev=/dev/sr4 extract_audio_to=. cdtext_to_v07t=./cdtext.v07
...
cdrskin: Writing audio track file: ./01.wav
cdrskin: SORRY : SCSI error on read_cd(48,0): [4 3E 02] Drive error. Timeout
on logical unit.
cdrskin: SORRY : SCSI error on read_cd(59,0): [4 3E 02] Drive error. Timeout
on logical unit.
cdrskin: FAILURE : Failure to read audio sectors
So the failure of cd-paranoia is explainable.
(Only its error messages are not very enlightening. libburn uses on Linux
ioctl(SG_IO) rather than ioctl(CDROM_SEND_PACKET).)
On a different drive i get from the same CD
cdrskin: SORRY : SCSI error on read_cd(2850,0): [3 11 00] Medium error.
Unrecovered read error.
I'll keep that CD well marked as example of a bad one. :))

Have a nice day :)
