You might want to rearrange your hardware after reading about the -immed
option in the cdrecord man page:
-immed Tell cdrecord to set the SCSI IMMED flag in certain commands
(load/eject/blank/close_track/close_session). This can be useful on
broken systems with ATAPI harddisk and CD/DVD writer on the same bus or
with SCSI systems that don't use disconnect/reconnect. These systems will
freeze while blanking or fixating a CD/DVD or while a DVD writer is
filling up a session to the minimum amount (approx. 800 MB).
Setting the -immed flag will request the command to return
immediately while the operation proceeds in the background, making the
bus usable for the other devices and avoiding the system freeze. This
is an experimental feature which may work or not, depending on the model of
the CD/DVD writer. A correct solution would be to set up a correct cabling
but there seem to be notebooks around that have been set up the wrong way
by the manufacturer. As it is impossible to fix this problem in notebooks,
the -immed option has been added.
A second experimental feature of the -immed flag is to
tell cdrecord to try to wait short times while writing to the media. This
is expected to free the IDE bus if the CD/DVD writer and the data source
are connected to the same IDE cable. In this case, the CD/DVD writer
would otherwise usually block the IDE bus for nearly all the time making it
impossible to fetch data from the source drive. See also minbuf= and -v
Use both features at your own risk. If it turns out that it
would make sense to have a separate option for the wait feature, write to
the author and convince him.
Hope that helps,
