I own a VGN-A317M Sony VAIO notebook.
The optical drive is a SONY DVD RW DW-D56A, which had worked flawlessly under Windows for about one year. Initially, I also performed the official firmware upgrade from PFS2 to PFS3.
A couple of days ago I tried to record a DVD-R under Linux, with K3b/cdrecord (this was the first time, I guess).
The drive simply stopped to work, under any OS. It only ejects the tray under software control.
I have re-flashed it with PFS2 and PFS3, both with the official tool, DFreaks Liteon tool and mtkflash, but to no avail. The drive does not even spin at boot time, if loaded with a boot disk.
Any advice? Thanks a lot in advance to everyone.
