-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Since I have two DVD/CD rewritable drive units in two different boxes, it occurred to me to swap the two and see what would happen. Here is the result:

The question now is why one drive would work but not the other. The working box has a Gigabyte GA-EP43-UD3L mainboard with an Intel dual core CPU. The operating system is Debian Lenny. The DVD/CD drive which worked is a LG model GSA-H55N dating from 2007-09-12. The one that did not work in this box is a Sony model DW-D26A dating from March 2005. Previously this drive was used and worked in an Intel P4 box, the mainboard of which was a DFI dating from before 2002. This box has been out of service for at least a year and is due to be recycled. In the Gigabyte box I had put the Sony drive instead of the LG one because I preferred the colour of the face plate on the former -- beige instead of black. It would seem that in this case practicality trumps aesthetics. I would still like to know why the Sony drive would not write (it did read) in the Gigabyte box and fix it if possible. Could it be a firmware problem?
