CD recording problem (Ricoh drive, Linux)

[Stephane Bortzmeyer]

I record CD on many different machines, with many different drives, and I 
always thought I knew how to use cdrecord. But I have a problem which I cannot 
solve. Since the drive is connected to an Adaptec 294X, and since I use the 
same model of drive without trouble with a 284X, there is may be a SCSI 
adapter problem and that's why I write on this list, after an unsuccesful 
attempt on comp.os.linux.hardware.

On one machine, recording seems to be fine (cdrecord doesn't complain) but 
reading the disk makes many errors in the kernel.

For an ext2 disk:

scsi0: MEDIUM ERROR on channel 0, id 5, lun 0, CDB: Read (6) 03 50 06 01 00 
Current error sr0b:00: sense key Medium Error
Additional sense indicates No seek complete
CD-ROM I/O error: dev 0b:00, sector 868378
EXT2-fs error (device 0b:00): ext2_read_inode: unable to read inode block - 
inode=107745, block=434189

For an ISO one:

Max size:128716   Log zone size:2048
First datazone:32   Root inode number 65536
ISO9660 Extensions: RRIP_1991A
.. Directory not in first block of directory.
Backlink not properly set 150 a9b70.

The problem is reproducible. I've never been able to record one CD properly.

I believe I tried everything, reading xcdroast and cdrecord documentation, as 
well as <http://mp6200.home.ml.org/>:

- driver Adaptec 4, 5.0 or 5.1 up to pre11,
- lowering speed of the drive in the Adaptec BIOS setup (since the Ricoh is 
asynchronous, I believe it is useless?),
- checking that disconnection is indeed enabled,
- checking termination several times (the other disks on the bus have no 
problems).

Here is the current setup:
