That's the question I'm asking. I am an owner of the LiteOn iHAS524-T98 A which I have since 2010 and I love that drive, especially the LabelTag feature. Unfortunately this model seems to be discontinued, and some weeks ago I had the unfortunate event of having a CD-R explode inside the unit. Don't ask me why, but it did exploded while using the SmartErase feature. Well, after opening the drive and take out all of the shattered plastic inside, it happened that the laser went bad after I put a CD and DVD inside. At first I saw the iHAS124 was still being sold, but unfortunately this isn't an acceptable solution since my drive is an A revision and the 124 drive is already in its E revision, so no crossflash seems to be possible. Luckily, after searching I found out the laser pickup unit so I went and purchased it. Took 2 weeks to arrive, but after it was here I replaced the drive laser and I gave it life again. I just hope my iHAS524 don't die or else I will loose the LabelTag feature for good.
Here I post some screenshots of the drive internals for those interested:
