Do all LiteOn drives read into the Lead-in and Lead-out? (Lite-On LH-20A1S)

[qanda]This thread is about the Lite-On LH-20A1S. Click here to see full specs[/qanda]Hi there, can you guys tell me if all the LiteOn drives read into the Lead-in and Lead-out?
More specifically, does the LH-20A1S read into them?

Thanks in advance


#2

The other drives of the LH-20A1 series do read lead in and lead out, I so think the 20A1S will read it too


#3

I think so too, I just want to be sure

Are you sure? My LH-20A1H does not read into lead-out, only lead-in. I used EAC to test the overreading capabilities and this is what I got.

#6

I think I remember something about my earlier LiteOn drives (1635S, 165P6S) not working properly when enabling overread into lead-in/lead-out in Exact Audio Copy, even though CDSpeed claims that the drives support this.

So it’s possible that CDSpeed and EAC disagree on this also on the 20A1 series.

I cannot test this right now however, so please take it with a grain of salt.


#7

So do you guys think it’s safe to assume that all drives in the 20A1 series will have this feature (at least according to CDSpeed)?


#8

When I enable the overread into Lead-In/Lead-Out option in Exact Audio Copy when using my LiteOn LH-20A1P drive, the last track ripped has a “timing error” at the end and the rip is not accurate according to the Accurate Rip database.

When overreading is disabled, all tracks rip without errors and are accurate according to Accurate Rip (in Burst mode).

So at least as far as EAC is concerned, this drive doesn’t (properly) support reading from Lead-Out, and the same is probably true for the 20A1S.

In Secure mode I’m having a problem getting an accurate rip of the first track on my testing CD!?! :confused:


#9

Thanks for the report DrageMester, I guess I’ll be looking for another drive


#10

I run the CD Speed test and this is what I got. It supports overreading as posted in the review. But why CD Speed says that it supports overreading into lead-out and EAC says that it only overreads into the lead-in? I don’t get it.



#11

juancdg can you try ripping the last track of that “The Police” cd in EAC with the Overread into Lead-in and Lead-out option on and off and see if you get different CRCs or any error (like DrageMester)?

Thanks


#12

@ssjkakaroto: I ripped the cd with EAC enabling and disabling the overread option, and the results were like DrageMester said, there was an error at the very end of the track and it wasn’t ripped accurately. I have posted the logs, you can check.

Thanks a lot for the report juancdg


#14

Could someone test this on a 20A4 series in EAC to see if the results are the same? This is a big reason I placed my order for one. Cancelled until I find out for sure that it’ll read into lead-out in EAC.


#15

Hey Telkar, I guess we’ll have a hard time finding new drives that have this feature. It seems that the only brand that used to have it on all their drive was Plextor, but now there is none :frowning:


#16

If you can find an old Lite-On CD-RW Burner, all of the 48x or 52x’s supported it. Even some of the earlier DVD burners did, I had the things. They just wouldn’t write DVD’s worth a S***.

No audio caching, C2 error info support and accurate stream, overread support, ISRC/UPC reading and writing support. This drive seems to be ideal for ripping audio CDs with EAC.


#18

packetloss, I think you have to test with one CD that EAC recognizes as a test CD in the Offset / Speed tab. It can happen that there’s no info in the Lead-out with the CD you tested, so even a drive that can’t overread will work.
You can create a offset CD in the Write tab.


#19

@ssjkakaroto
I just did a test with the EAC offset CD I created, and it failed (accurate rip with overread off, sync error with overread on).

However, I tested a couple of other commercial (pressed) CDs, and the iHAS 120 ripped them accurately with overread on (the example I posted above is from a commercial CD also). This is weird to say at least, but since the drive could not accurately rip the test CD with the overread option enabled, the conclusion has to be that it does not (fully?) support this feature.


#20

packetloss, did you rip the last track of the cd? Because when I rip any other track with overread on, the rip is accurate.
