I am bamboozled. On Monday I was burning discs on the fly @ 7.5 using herrie fw. On Tuesday, it started taking 30-40 minutes to accomplish on the fly again. I had the burner in a USB2.0 enclosure, using a 2.0 card in my laptop. I then took out the burner and installed my tdk420N inside the enclosure and it burned a perfect disc @ 4x's no problem in 13 minutes. I took tha nec out of the encolsure and hooked it to my desktop and am burning on the fly @ 8x but it still took over 18 minutes to complete using herrie's new dl fw.Has the drive gone bad? What else am I to do? Please help me. Can the TDk420N be flashed?
