Hello,
I recently tried to burn some datas on CDs and DVD using a SATA burner
and the latest 2.6.18.2 kernel... using NeroLINUX. (It is controlling
the device by sending SCSI commands over the 'sg' driver)
Please note that the sg interface is depreciated. It is now recommended
that you send the CCBs directly to the normal device, i.e. /dev/hdc.
The burn process works like a charm, no problems at all. But it seems
that there are some slight problems with the READ scsi cmd:
Inside our software, we have a verification routine that will make a
sector-by-sector verification to check that everything that has been
written is OK.
The problem is that, on SATA devices controlled by libata, on some big
files (like for example a 600 MB file) the READ command seems to fail
and outputs garbage (not 1 or 2 bytes diff, but the whole buffer).
-> This problem does not come out everytime, and each time on
different sectors.
I'm not sure what you mean by "on some big files" as the sg interface
has no notion of files; you're just reading the disk sector by sector,
as you said earlier. Also by fail do you mean that the request returns
an error status? If so then the read buffer will not be valid.
