A lot of people have been reporting problems latley after flashing there Hitachis with LT 2.0 If after flashing your Hitachi plays random discs after flashing then the fix is simple. All you need is to tweak the laser or replace the laser. I have had this issue now with x2 Hitachis and fixed both in a matter of minutes. Rather than buying a new laser or messing with tweaking i just changed the whole carriage from another drive... 40 seconds and your done Also tested flashing another hitachi after with the laser cable removed and never had the problem of not reading discs aftwards.... Coincidence? Maybe... but also worth a try for the future.
