Yes, I know. Did this drive actually have a warranty to begin with, other than the reseller's 30-day return policy?
Hey, I can't help it. I love to take stuff apart.
Did the usual stuff. cleaned the lens, oiled the carriage rails and all that stuff. Lately it hasn't been making 100% C2-free discs so I decided it was time to do that. (got one clean write and the next disc had a bunch of C2s--it must be these Memorex/TY discs--then again, it did that with a couple of Fuji/TY as well )
On thing that I thought was going to be there that wasn't was the spindle auto-balancer ball-bearing thingy. I guess it doesn't need one. Maybe the W version has it? One thing's for sure: It's built a lot better than my old HP 8200a/CRX120E/140E.
I also like the stepper motor used for moving the carriage assembly. Sure beats a lot of crappy motors and gear assemblies that they use in other drives (see aforementioned HP), also the stepper with a screw shaft has a lot less rotational inertia (allows it to seek more accurately) than a "full-size" motor with a bunch of gears that ends up being a series of flywheels, hard to bring them to a stop when the correct location is found.
These Lite-On people really know their physics.
I also like the heavy piece of steel they used to help cancel out vibration--it's a nice touch.
Chipset? Big one is a MediaTek MT1508E and the smaller one is a MT1516E
