What is the deal with the firmware for the 4020i?
As far as I know, the 4020i was first shipped with version 1.14 firmware. From my experience, this original firmware, as well as the original release software, was buggy and was quickly replaced with version 1.20. I downloaded the 1.20 flash upgrade, and attempted to run it. According to the dialog boxes, it claimed to have completed successfully. However when I tried to burn CDs with the drive, I encountered several error messages, and when CDs did burn, they usually wouldn’t close correctly. I called HP about this, and they sent me a new drive, with 1.20 firmware on it. Version 1.20 firmware seems to be quite solid. I have burnt over 100 CDs with 4020i drives using this firmware and haven’t had any problems. Thus when the 1.25 flash upgrade appeared, I was rather reluctant to upgrade. However I’m told that version 1.20 does not do CD-XA discs correctly, and that 1.25 was the answer to this. Hence my reason to upgrade. I ran the flash upgrade, and it claimed to have flashed just fine.
