Hi,
I recently purchased an external USB CD-RW to use with my Sony Vaio 505TR.
The drive seems to be recognized and I can read data from it. I can also
pretend to write on a cd-r using the dummy mode of cdrecord. But when I
try without the dummy mode option the drive and laptop crash when cdrecord
goes into "Performing OPC" function.
I have since updated to the latest kernel (2.4.14) and tried also the
latest version of cdrTools (1.11) with the same outcome.
Here is some debugging info. Any help is appreciated.
This is the output from cdrecord, first in dummy (OK) then in real
(crash). This is with cdrecord 1.10, but it is the same with 1.11:
