Liteon LH-20A1P or Lite-On LH-18A1P

LiteOn / PLDS / Sony Writer Discuss, Liteon LH-20A1P or Lite-On LH-18A1P at CD and DVD Writers forum; As title says im looking at one off these 2 drivers. So far the Lite-On LH-18A1P seems to be getting more posts and media here, but also the 20 seems to have some great scans. Them main priority is dvd-dl and dvd writing. Cheers for your help

Both are the same. If you can get the 20A1P for little more I would go for this drive. The 18A1P can be crossflashed to 20A1P but you lose the warranty.

I am really jealous, I have tried all firmwares for this drive and cannot get a good burn @ 18X or 20X. Its fast alright but I am a little disappointed in the quality of the burn.

I own the 18A1P and the 20A1H. The 20A1H is much quieter.

I understand that noisy 18A1Ps are being accepted back under warranty.

FYI, there is no crossflash firmware for a 18A1P to a 20A1P, that I know off.

That's a little hard to answer. Something you will have to judge. I can tell you that my 20A1H is very quiet. On the other hand the 2 18A1P's I have are very loud and vibrate way too much. The 18A1P's I have are early production units and I would guess the later one's have been improved. Mine will not go back for warranty replacement but I may order a new one to see what improvements may have been made.

I have a Nov 06 manufactured LH-18A1P - makes about the same amount of noise as my other 16x drives e.g. Benq 1650 or Lite-on 16x 16P9S dvd-rom. Definitely sounds like some are louder than others.

Hello, I posted here before seeing this thread. I have this noisy type, it's really driving me mad with its vibrations. As I said, I need it only for watching, reading dvds and scanning (for burning I use asus1608P3S@Pioneer111L, which is a great burner), is 165P6S a better choice then in terms of silence? Cause I'm really thinking of an exchange in the shop I bought it.

Neal,

Mine is like an airplane taking off lol. Mine doesn't really vibrate since the drive fits in a bay very tightly. Just super loud especially during ripping, but not that loud during reading and writing.

I did not think mine was either....
I wonder if have another burner on the same ide cable as a slave is having any affect

I may throw a second ide cable in and set both H22N and LH201aH(master now) as master

So far I have tried...

1). Set H22L to master & LH-18A1P to slave

2). Set LH-20A1H to master (only drive connected to the IDE cable) & SH-16A7S (SATA)

3). Set H22L to master (only drive connected to the IDE cable) & SH-16A7S (SATA)

4). Set LH-20A1H to master & LH-18A1P to slave

hmm noise is actually off no importance to me, as i run a core2duo 6300 @3.3 ghz on air =P

As for pure drive write quality though, i went for the Liteon LH-20A1P. Hope i made the right decision :P
