A Lite-On LH-20A1H, but none of the ones I ripped is included in the "dirty list" that includes those infected with the infamous rootkit (I wanted the G3 one at one point, but decided to buy another album).
Even then, although I ripped quite a few copy-protected CDs, those which are clearly marked as such, are HARD to obtain perfect results from, with constant spin-up and down of the drive, resulting in 1x speeds like you say, and the CRC never matches those stored in the AccurateRip database, so I bite the bullet, changed to burst mode and ripped IT (only one, for the sake for my patience) in a few minutes. Even though it's not a bit-perfect copy (by technical standards), it sounds perfectly fine to me, which is what matters. The type of music also helps :P
