Pioneer Correct Firmware

Just got Pioneer 2209/209UBK/209M. Shows the firmware on the drive as 1.34.
Pioneer firmware site shows the latest firmware as 1.50 which evidently corrects some problems.

Is it safe to change the firmware to 1.50? Looks like the changes are for high rotation problem and TL disc

Should I just leave it alone with 1.34. All 208 drives and 209 drives show FW of 1.50.

I don’t want to screw this one up.

There should be no problem updating the firmware to 1.50, the drive should be connected to an internal SATA port though, flashing in an external drive enclosure most likely won’t work.
