Thanks for your response, which does give me more confidence. But things that cause me concern - Following is from "The Windows Advisor" re CD/DVD burner Firmware updating;
"Normally the file is zipped. After unzipping there should be two files, the Firmware Update and a flash program (.EXE file). Some manufacturers separate the flash file and firmware update."
So- first concern - the file from CDRinf is an .exe file - is it a zipped file, or is it only the flash? What is the difference between what Windows Advisor calls the flash and the Firmware Update? I had understood that the Firmware Update is the flash.
Next - to apply the flash - Windows Advisor says; (for XP) Create a MS-DOS startup disc and copy to it the Flash program and the Firmware Update. Put the disc in the computer and restart. At the DOS prompt enter the flash program name, and the flash program introductory screen will appear. Enter the path and name of the firmware file on the floppy disc. Enter the exact name of the Firmware File on the floppy. Once flash process complete restart the PC.
Windows Advisor also says some flash programs don't have a GUI, in which case you have to figure out whether the drive is a Primary Master, Primary Slave, Secondary Master or Secondary Slave.
Would appreciate your comments.
Another thing, - I was looking for an update for a Sony CRX320EE, but can only find a CRX320E. Do you think these are the same?
