• New!Problem with burning CD's
Question by badsubby, Sunday 9th of November 2008 09:23
Hi,
I recently purchased a Lite On DH20A4P. The dvds burn fine but the cds are having a little bit of trouble. I am trying to burn about 15 songs onto a cd but it only burns around 7-8. The rest are scratchy and dont play well. Some are not even burned. It says complete in WMP but it is NOT complete. Some time it gives error while others it doesnt. I use TDK CD-R.

Please tell me what I can do to resolve this issue? Thank you.
Answer by bigmike7, Sunday 9th of November 2008 09:35
Yo-

LiteOn burners are known for not being the greatest CD-R burners out there - BUT - they are also known to be some of the best reader/rippers around - the 20A4P in particular-

The Optiarc 7200A is a very good CD-R and DVD burner-

Would suggest a setup where the 20A4P is the reader/ripper and the 7200A is the CD-R DVD burner - along with a good audio burning program like EAC - a free program that can be downloaded at www.exactaudiocopy.de -eh!!
Answer by mognegna, Sunday 9th of November 2008 11:27
I agree with bigmike7, A3 series is surely better than A1/A4 series, especially for the jitter. We don't know, at the moment, about the iHA* series.
For audio CDs I use my Plextor PX-755A.
Answer by Hemispasm, Sunday 9th of November 2008 15:08
Well, it wouldn't hurt though trying also with some other CD media and see what happens.
Answer by badsubby, Monday 10th of November 2008 03:14
I'll try a different type of media discs. I have a secondary samsung cd burner which only works when you burn at very slow speed but that'll work for now.

This burner was actually supposed to be the replacement lol but I guess not. Thank God the old burner still burns cds but not dvds.

So cd's w/ Samsung and dvd's w/ Lite On. Works out, I guess.

Thanks guys.
Answer by Telkar, Monday 10th of November 2008 05:39
Drop the burn speed down to 16x on your Audio CD's. One, jitter is kept to a minimum at that speed, and two, it burns a perfect Audio CD on my 20A4P.
Answer by negritude, Monday 10th of November 2008 10:54
The kind of problems that were being described don't seem to have much to do with anything regarding the 20A4. Sounds to me like the person is burning too fast and/or using crappy media. Before you waste money, make sure you're burning audio at 16x, and as was suggested, use a program like Exact Audio Copy (EAC) for audio burning.

And no, the 20A3 is most definitely NOT surely better than the 20A4. That's pure opinion and conjecture.

I have a DH-20A3H and I have had, just for some tests, a DH-20A4H and in my opinion the A3 series is better for CDs, especially for jitter.
For CDs A4 series is like A1 series.
See this thread.
Answer by badsubby, Monday 10th of November 2008 19:14
I burned at the lowest speed and I didnt receive any error. But, when I played the CD's the last few tracks were missing lol. I'll try some other kinda media beside TDK and I'll report back.

I'll also check out EAC. Isnt it a ripper program or something like that???
Answer by mciahel, Monday 10th of November 2008 21:22

Indeed. It also incorporates a CD burning engine.
Look here: www.exactaudiocopy.de
Answer by badsubby, Tuesday 11th of November 2008 03:37
Hi,

Is there an easy way of burning songs in EAC lol? I dont know how to make a .cue file and this seems way more messy than burning in WMP, Deepburner or Nero for that matter.

If someone knows how to burn cds by "adding files" in EAC, please let me know. Thanks.
Answer by yesgrey3, Friday 14th of November 2008 14:14
If you select Burn CD-R in EAC, a new dialog appears.
If you already have the cuesheet file, you simply load it in the File menu.
If you don't have the cuesheet file, you could setup your own CD using the options in the Layout menu. There are three option for appending files to your compilation. You have to read the Help file to learn the difference between the different options: Index 1, Index 0 & 1, ...

It's very easy, try it.

• New!Moserbaer Liteon DH-20A4P - Firmware Update
Question by adityamunshi, Friday 7th of November 2008 19:17
I just bought a Moserbaer branded DH-20A4P. Now it came with a stock 9M74 firmware (posted in announcement thread) and refuses to accept official Liteon firmware.

How do i flash it with the latest Liteon firmware ? And will it void the warranty, even if the flash is successful ?

Download Flash Utility v2.2.4. Run it and where it says status, it will say either A or S.
Answer by C0deKing, Saturday 8th of November 2008 07:28
Try using the "DUAL" 9P59 firmware in this thread to flash to LiteOn firmware:

• New!Liteon DH20A4P
Question by KingGnome, Wednesday 5th of November 2008 11:21
Ok so I replaced an old burner that stopp burning with this liteon dh20a4p and all was well. Well except that it stopped burn any type of DVD+r discs which really doesn't bother me to much but if anyone know how to get it to do that it would be great. The main problem started whyen it didn't want to burn anything anymore. It gave me a burn fail when i used nero, or sonic or power iso or any other software i was using. I finally read somewear t try to update the firmware and proceeded to do so with the 9P5P firmware update which I can't rememebr if it actually was an update or if I was current. I rebooted when asked an everything started to burn just fine on my -R media. However now it still wouldn't burn onto my old +R media and now it wouldn't burn any CDR's. At that point I said fine at least it burns something and went about my life. Once again it's giving me trouble no matter what the media type is I've tried fdiffrent maunufactures of media and tryied to update the firmawar several tymes and rebooted in hopes that hey maybe it'll let me burn just the -R media again. Can someone please help me? I'd love to get full use out of this "superallwrite" or at least let me burn a dvd, ... any dvd. Here's a few specs on my comp:

Answer by pfloyd1, Wednesday 5th of November 2008 13:58
What brand media are you trying to burn with?
Answer by KingGnome, Wednesday 5th of November 2008 17:13
Nexxtech 16X DVR-R (circuit city brand)
Nexxtech 8X DVR+RW (circuit city brand)
Memorex 4X DVD+RW
TDK 16X DVD-R
Sony DVD+R unlabeled on the disc as to it's speed

Philips CD-R

all of these are failing
Answer by KingGnome, Wednesday 5th of November 2008 17:27
I should prolly clarify a little. When i use sonic it caluclates the speed and then says 64K burned and then it fails everytime. When I use DVD shrink I belive it uses nro for the burning and it fails. POwer iso fails as well after clicking burn. It doen;t make coasters even for sonic when it gets to 64K just an error and an ejected disc. Hope that helps.

Most of those are crap media, and I even wonder if the Sony media is genuine. The NexxTech is the absolute worst and should be thrown in the trash. The TDK DVD-R burns horribly. The Sony media should have some indication of it's speed rating, and if it doesn't, it could be that it's only 8x media and you're burning it to fast (overspeed) or it's fake.
Answer by KingGnome, Thursday 6th of November 2008 02:16
Actually I use nexxtech because I'be have the least amount of problems out of any type of media i've ever used and it's like 50 DVD's for $9 dollars, palys on any player and has never given me a problem.

Well so is you single core processor, tiny hard drives and dated video card that can't even play any of the current games. Do you have anything constructive to say like what media you recommend I use, what program you use to burn and rip dvd's or expianing what the MIDS number is? and I'm well aware my computer isn't top of the line but it plays Far Cry 2 and Fallout 3 prefectly fine... yes both are available by torrent.

1. I dont play games. I do video work and the system works just great for me.

2. Like stated above, you keep contradicting yourself.
3. Buy good media like mentioned above.
4. I dont pirate.
Answer by Albert, Thursday 6th of November 2008 13:23
Uninstall whatever program made the virtual drives. [Daemon Tools, Alcohol, etc]

Try better media.

Try writing a disc with ImgBurn. It's a free application, and its log is usually good for troubleshooting.

• MY DH-20A4P may be dead
Question by sorley1975, Friday 17th of October 2008 12:12
Help Please

I just recently bought the above DVD burner, I am using it via a usb caddy,

Windows wasnt reconizing it as a DVD burner only a Cd burner,

I tried updating firmware to 9P59 now it does nothing,

When I use Flash Utility or The 9P59.exe file,

I just get error msg saying, "Unable to Flash 'Contact Vendor'"

It's current firmware is OP5A

Any help would be great, or is it toast

Thank

Pete

Hi, try connecting the drive on an IDE connection on your machine, and then flash. Some USB caddies doesn't work very well.

I hope you mean you currently have 9P5A in there and O was just a typo. If so, then 9P5A is NEWER than 9P59, so official flasher won't allowing an older firmware to be flashed.
Answer by Albert, Friday 17th of October 2008 19:32
0P5A is the "bootcode revision" as shown by MCSE [see screen shot below]. It is the firmware version displayed for a drive that is in "safe mode", as far as I can tell.

I'd try to do what juancdg says; connect the drive internally instead of the USB enclosure to flash it, and it should work.

And as for your original problem: that is a quirk with Windows. Windows XP's built in burning engine does not support writing to DVDs. You must use a standalone burning program.
Answer by superhero, Friday 17th of October 2008 19:36
Are you sure the firmware is "OP5A"? If it is 9P5A, it would be newer than 9P59.

Sorely1975,

Sorry about your problem with the drive. I too on the same boat with the same drive. Hope this is not a common problem with this drive. I just had it less than 7 mos, and now my lab tops would not recognize it either.

Please share your experience here when you do get a chance to hook it up with a desktop.

I was hoping that we could use C0deKing's flash utility to do, even in an external enclosure. But notes above seems to indicate that it can't be done so, please confirm.

Any way, as I don't have a desktop nor have any access to one around here, please share your result here.

Wish you all the best.

Oh, that explains it. Laptops always have port related problems due to weirdness with power saving and chipsets. I'll bet if you hooked the same drive up to a desktop PC, the problem might disappear. Never flash an external drive with a laptop. Find a desktop to flash it with. Laptops are dangerous.

• No sound from Dvd player
Question by demon41, Saturday 27th of September 2008 12:44
Hi, I have just installed a DH-20A4P08c in my desk top running XP Pro, plenty of Ram and HDD , and when playing DVD's there is no sound. the dvd drive plays CD music OK, also it will play sound from a made up DVD, but not from bought DVD's.
I copied a bought DVD just to try it and when played back no sound played, the sound is there , it plays with sound on a DVD player OK.
I have installed it as the slave unit, using my normal CD drive as the main, they show it in the instuctions as the main, but I didnt want to shift that.would this make any difference?
are the connections on the IDE cable both the same?.
I have done a reinstall ( repair) from the installation disc ,just in case it missed something on installation. still no joy.

It reads other installation DVD's Ok.
Hope you can help, Cheers Des.
Answer by demon41, Sunday 28th of September 2008 10:47
Hi, Just to let you know that I have solved the problem , it was because there wasn't a DVD programe on the desktop, the disc that came with the unit is only Nero 7 essentials, . So I loaded on Cybrlink Power DVD and it now works , once I have opened the DVD in that program in will then play the sound in Media Player.
Thanks , Great site, Cheers Des.

• Lite-On DH-20A4P: Burning Problems - Power Calibration Area Error
Question by SyntheticSocks, Sunday 7th of September 2008 03:03
I've had this Lite-On DVD/CD burner for a little less then a year then it started to not work.

Nero would stop right in the middle of burning an abort. I switched over to Burn4Free and it still won't burn.

When I click on the D: in My Computer I get this Error:
"D: Not Accessible Incorrect Function"

I figured it was the new burner so I switched to my disc drive that only burnt CDs. Alas, the same message.

I read the error that Burn4Free would give and it was

"Writer Error [Medium Power (Power Calibration Area Error)]

I'm currently running Windows XP

Any ideas guys?
Answer by ripit, Sunday 7th of September 2008 05:09
Disks have a test area on them where the drive can test write to calibrate laser power for the disk. power calibration error means that this test write has failed. The most likely causes are crappy media, a dead or dying drive, and a bad power supply. Try different media. If it is getting that error on two drives with different media, check out your power supply fast!!! If it is an oem computer, they tend to use cheap power supplys (even expensive brands like sony often use cheap power supplys). If your power supply fails, it can kill anything/everything in the computer (motherboards are very commonly killed). Download something that can monitor voltage (mb5, speedfan etc). Be aware, they are not always accurate but its a starting point. Perhaps try monitoring voltage while you try a burn. You can also try reducing power usage (unhook usb/firewire devices, unplug power to extra hard drives etc). You can also test with a multi meter if you have one. If it is testing with bad voltages and/or if reducing power usage fixes it, stop using the computer and replace the power supply fast before you kill something.

I flashed with 20A4P.9P59.patched-fb-eos-eoht.exe (the most recent dual version) and I got this scan after one succesfull burn at 12x. I then cleared the learnt data with Eprom, but it still produced errors. Next I reverted to the Lite-on 9P59 firmware and then it produced the second scan (even after clearing the data. Is there anything I can do to fix this. Before the upgrade, I could burn the Prodisc R04 without issues.

• return policy for lite-on drives
Question by marcodeo, Saturday 26th of July 2008 11:09
HI,

My DH20A4P (9P59) behaves strangely, and I'm taking into consideration the hypothesis of returning it to the seller. Here in Italy, within 15 days you can have the product changed, if defective, or you can even ask for a refund. But now it's already 20 days I have it, so I must send it through mail (I bought it from a WWW shop), then wait God knows how many months, etc..., so you may understand why I'm hesitating. Moreover, the drive actually works, except that:
- CDs are burned very badly, with several C2 errors even on TY media (like Verbatim Pastels), which is innatural. Nero "verify Written Data" function discards the discs in every case. However, the drive reads easily CD-Rs written by other burners, CD-ROMs, etc. It doesn't recognize CD-RWs as such, and these must be erased with other drives, then they can be burned, again with bad results.
- DVDs are burned fine (according to scans made with other drives). However, the lite has many difficulties in reading DVDs. If I try to copy a data DVD - known good - just some files would be copied, before an "Invalid MS-DOS function" error appears. Nero Verification also fails in every case. However, as I said, all DVDs, until now, had been burned correctly, with quite low PIF/PIE error averages, and are easily read by other drives.
- If I try to flash the 9P59 firmware (not an upgrade then, just the sole firmware available on the Lite-on site) I get immediately an error, and the flashing doesn't start. Also, several utilities from Codeguys don't work (e.g., the EEPROM utility doesn't save anything).
Well, of course DMA mode is enabled, I swapped cables, I've tested the drive with two different PCs (Win2KSP4 & WinXPSP2), etc. etc.

So, what do I do? Have it replaced? Would they make some stories?

Thanks a lot for you patience.

Just my opinion:

If you are within the warranty period, the manufacturer can repair it if they think it is defective or they can replace it with a refurbushed model.

If they find evidence that you flashed your drive, especially with a third party firmware, they could void your warranty.
Answer by larc919, Saturday 26th of July 2008 16:01
If the drive is flashed back to stock f/w, I doubt anybody is going to check that closely. Especially if it hasn't been cross flashed to another model.

• Inconsistent dual layer scans
Question by Eiji, Thursday 24th of July 2008 05:32
Believe it or not the scans below are from the same disc scanned at the same speed only hours apart. Why is there such a radical difference in scan quality?




Answer by Albert, Thursday 24th of July 2008 06:09
I'm just guessing maybe a result of drive temperature [semi-extreme guess, but it happens].

Do they get any more consistent at 4x?

Well the quality is better at 4x scan speed but which scan is a true representative of this discs quality generally?
Answer by Eiji, Friday 25th of July 2008 10:19
bump!
Answer by Womi, Friday 25th of July 2008 10:56
I think its a temperature issue, too.

What brand are these discs?

They are branded Aone Plus Double Layer.

So is it due to hot temps or cold temps?
Answer by Albert, Friday 25th of July 2008 15:24
When my LiteOn drive run hot, they tend to encounter more errors.

So if I burn a disc and immediately scan it, I will get more errors than if I waited.

When I had issues with my old A1H, they would occur after the drive had a chance to heat up a bit.

Did you burn the disc and then scan it, or...? Did you scan one when the computer had been on a while, and the other after a cool-down? Or some other situation where the temps might be different?

Yeah I burned the disc and then scanned it the first time and then the second time I scanned it after a cool-down.

Does this apply to burning too? If I burn one disc after another will there be more write errors on each subsequent burn due to heat?
Answer by Albert, Friday 25th of July 2008 20:32
There's a small possibility that it could occur, though I'm not sure it would be as pronounced as this scanning difference would be.

Nevertheless, I ALWAYS recommend you avoid burning discs 1 right after the other for that very reason. Giving the drive a small break to breath [5 minutes with the tray open, at the least, assuming you're not in a dusty environment] will give your drive a chance to do a better job and last longer.
Answer by Eiji, Saturday 26th of July 2008 01:11
Is this the case with all DVD writers or only Liteons that decrease in scan and burn quality if you do consecutive burns?
Answer by Albert, Saturday 26th of July 2008 01:46
Sorry, but I don't know. I haven't seen anyone question how heat affects quality directly. It's just been suggested that all drives get a break for cooling purposes.

• Lite-on Atapi DVD A DH20A4P won't read blank media
Question by mfabzak, Wednesday 23rd of July 2008 02:52
I just purchased the OEM Lite-on Atapi DVD A DH20A4P from Newegg. I installed it and was really excited until I found out the drive will not recognize any blank media put into it (DVD +R, DVD +R DL, CD-R all are unrecognized). When the drive is opened or explored, the computer displays the following prompt:
"E: is not accessible
Incorrect function"

I'm running firmware version 9P59, and I am at a loss as far as how to help the drive recognize what is going on. One interesting thing is when blank media is inserted, the drive (looking in My Computer) says it is a CD drive. When no media is in the computer, it says it is a DVD-RAM drive. The drive does play back movies though.

Please Help!
Answer by Albert, Wednesday 23rd of July 2008 04:29
Welcome to CD Freaks.


The error you get is normal for blank DVD media, although not for blank CD media [usually].

The drive will switch to "CD Drive" in Explorer with a blank DVD inserted.

The drive will show as a DVD-RAM drive in Explorer with no disc inserted--as it is a DVD-RAM drive [in addition to the other things].

Try with a dedicated burning software such as ImgBurn to see if the drive will recognize blank CD-R properly. It could be that your drive is just not set up to record CDs with Windows' built in burn engine--which is how most of us around here recommend it.
