I tried upgrading my HP 8200 (4x4x24) to a 9300 (10x4x32). I know it’s a bit of a drastic change, but the drive was just sitting around useless, so I figured what could it hurt. The flash went well and neroinfotool reports all the new capabilities. Wrote succesfully at 10x and then opened nerocd speed. On the HP, scandisc shows all green except the last sector, which is bad (doesn’t support damaged). I didn’t trust the results, so I tried it in my generic cdrom drive, which surprisingly does support damaged sectors. Came up as 97% damaged, the last sector still damaged, and a single good sector near the end.
Not to worry, I have the 8200 firmware which I am going to flash back. But does anyone have a 9100 series firmware in .bin format? And also, which was the first HP writer to have buffer underrun prevention technology? Even if I have to stick at 4x, the buffer underrun protection would be a nice additional feature. The drive is supposed to be based on a Sony model, which one and what was the first sony to have buffer underrun prevention?
