Slow External Liteon 40x

Hi, first post so here goes. I have bought the above to run on my laptop via a usb2.0 pcmcia card. I have copied data from the drive and it seems to reading data at full speed. When I write to the drive I set it at 32x speed but it still took around 10-11 minutes do burn a full CD. The software it came with is Nero and whilst burning the record buffer level / state is all over the place from 10% thru to 90% ish. I have run the drive speed thing in nero and it came out at being able to write at 38x. Any ideas

Laptops have slow Hard drives so it could be your HD aint fast enough. You could try it on a faster Desktop PC.

Does the HD have DMA enabled?

Probably comes down to either the PCMCIA card, and/or the CPU.

I have a Dell Inspiron 8000 (1 GHz/512RAM) with native Firewire, and I also have a LiteOn 52246 in a firewire box. Burning at 52X is not a problem, buffer is above 95% all the time. Hard drive is a pissy 4200 RPM, so doubt the hard drive is your problem, and also 2000/XP enables DMA default for hard drives.

How fast is your CPU, RAM, and do you use good quality media?

Also what OS do you use, and which USB2.0 drivers do you have loaded, MS’s or card manufatorer’s?

Hi sorry i didnt give enough info for you to help. Right here we go
Laptop SOny VAIO FX 801 1400 amd athalon, 256 mb ram, 20 gb hard disk windows xp and i have service pack 1 installed. The PCMCIA card is PCMCIA (Cardbus) USB2.0 Controller KW-2002-2 from Kouwell Electronics and i have installed the drivers the card came with. Cant tell you what speed the Hard disks spins at because i dont know how to find out. Media not to sure about, although i do use the same media on my internal burner on my base unit and have never had any trouble. Hope that helps the diagnosis and thanks for all the replys so far

hey OZ,
my 8000 with a 750hz cpu 256mb ram W2000p will only read discs at 16x (on my liteon 40125s in firewire box) but will burn at upto 32x. - any ideas?

Your specs are certainly in top, I would agree with earlier post, try the drive on a desktop ot other notebook to see if it’s the drive itself, these things do fail, I have had several drives die on me, and some were only a few months old, DAO drives are not uncommen either.

Other than, all I can suggest at this stage is to try the USB2.0 drivers from Microsoft’s udate site.

Oh just remembered which version of Nero do you use, might wanna try and grab a newer one, but stay clear of latest seems to be buggy for many

I have no idea, have you checked in read options that it’s set to Max, Nero has a bug, sometimes after doing a couple of CD’s, on my Dell it drops read speed option to 12X without me telling it to, so manually resets it to max, and it does so.

Read speed on a clean disc sometimes go all the way up to 56X for me, and burning at 52X is not a problem either, but I stick to 32X though.

Which Firewire case do you have, I use one from a Sony CRX1600L, it originally had a 12X8X32X in it, but I have now tried a Sony CRX1611, LiteOn 40125W and finally current LiteOn 52246S

Eventually a LiteOn DVD burner will find it’s way into the same box :smiley:

Hi, thansk for the reple. I made the registry change for nero that I found on here somewhere to show the actual burn speed. I have upped the ultra buffer in Nero to 80mb and then tried to burn a cd. The burner sets of at about 24x and never gets over this and then with about 10% to go it bombs out right down to 1.5 /2 speed and then obviously takes an age to burn. I am going to try and see if I can try it on my friends desktop to see if thats an quicker but I am starting to think its the drive. I only bought it last friday :frowning:

Thanks for the help so far

Hi, Back again. Having convinced myself that the drive was faulty I took it back to the shop and swapped it. I have flashed the drive to the latest firmware (7s09) then burned a cd. Now it didnt burn at full speed but it was a lot quicker. I was wondering if someone could look at the LOG from nero and tell me if it looks ok, it means sod all to me. The burn was for about 700mb

Well so we are on the right track at least.
I’m no expert on Nero log files, but looks ok, no errors in it as far as I could see.

Did you set it to 32X, or did the media check drop the speed, as in do you use 40X rated media?

Was the buffer steady all the way during burn?

What did you burn, noticed it was in Mode2/XA

Your hard drive is a 4200 RPM

Do you have anything else open during burn, not much RAM free?

The media dropped to 32 by itself, the buffer was up at 85 - 95 for about 2/3 of the burn and then it started to drop down to about 20-25. I burned about 120 mp3 files. Do you think its just the fact that the hard disk cannot transfer the data quick enough. I cant think what else I had opened at the time so not so sure about the ram. Thanks for the quick response oz btw

OK, that should mean your media is not rated at more than 32X

Get this and check what it says:

http://www.liteonit.com/zip/SMARTBURN.zip

Also, you should burn in Mode1, NOT Mode2/XA.

Mode2/XA is for VCD/SVCD.

Obviously when burn gets closer to end speed increases, and the data flow cant keep up. When was the last time you did a defrag? If your 120 MP3’s are all over the hard drive in a couple of thousand fragments, that could be the cause.

A 4200RPM drive should be able to keep up without working up a sweat, as mentioned I can burn at 52X with same 4200 ROM HDD.

Mayby you could go into settings in Nero and increase the UltraBuffer to it’s max of 80MB, and then do a test/simulation to see if that beefs things up.

But first of all run a defrag!

Oz, you are on the ball today. Defragged the hard disk last night so i dont think its that. I will change the mode setting, thanks for the tip. Heres what smartburn says for my media

     ATIP Lead-in = 97m 27s 19f
   Norminal Capacity = 702.83MB (79m 59s 74f)

Disc Manufacturer maybe = Unknown
SMART-BURN Speed Limit = 32X

I will this a go and let you know

things get stranger, i ran a simulation burn and it an age and ran at no more than 4x. I then ran Nero cd speed and that took over ten minutes b4 it did anything and when i tried to cancel the program ended abnormally and I couldnt stop the Liteon without switching the power supply of. I eventually had to reboot the laptop too. Once i rebooted i managed to get 1 cd speed to run and then the same thing happened. I think i might try some other software becuase i am begining to think it might be nero.

Did the above happen after you changed Ultrabuffer? Then revert to Automatic!

Have you had a chance to try out the drive on a desktop with native USB2.0?

Still suspect the PCMCIA is not up to scratch, did you try and upgrade the USB2.0 driver with the one from Microsoft’s update site, you said you used the one from the maker of card?

Yes many variables in this 'game" :eek:

c_m:

I have the exact same problem. My drive was working fine. I don’t recall exactly when it started to go bad, though. Originally, the ‘record buffer level/state’ was in the high 90’s. After something went bad, its anywhere from 18 to 92 and constantly varying.

Its not any slower that when I first got it. I can copy a CD in about 6 or 7 minutes (I have a TDK 12x burner) when its reading off of another (dvd) drive. It takes twice as long (obviously) if I image it to my hard drive, then to the CD-R.

Knowing all of that, it can’t be my computer or hard drive, since they haven’t changed. I have gotten all of the upgrades (currently 5.5.10.56), so it could have been one of them. But you’d figure this would be reported if it was common enough to be an upgrade bug.

I’ve tried everything except turning of the HDD S.M.A.R.T. Capability on my hard drives. Do you know if that is running on your system? I don’t really think its my problem, if when I do a CD Copy, its really not using the hard drive.

I’m all out of ideas.

hey connor_macloud:

I had similar problems with my 48125w in a usb case and a usb2 pcmcia card. No matter what the hell I did, I couldn’t get it to burn straight thru unless I did it at 24x. I’ve been thru 3 usb cases, not seeming to get the good ones that some other ppl have and decided to just scrap the whole usb thing and go firewire (especially since I have that natively). Might not be the answer u want to hear, but u probably either need a better usb2 card or case or both, or stick to 24x burning or just go firewire. Took me about 10 months to figure that out.

WOW completely forgot about this thread. I eventually gave up and took the liteon back and got a freecom one instead. Alas still no joy with that either. The best I can burn at is about 10x using suitable media and everything. I can only think that its a compatability thing between the laptop the pcmcia card and the burner. I can use the external fine on my desktop at full speed so who knows. Why dont laptop makers stick UBS2 ports on.

Oh hum the joys of PC’s

Difference betweem 24x and 40x is only about 20seconds. Are you really that worried about a cd taking 2mins 50 vs 3mins 10? :expressionless:

Usually dedicated USB burners have extra cache as well.
The USB interface is generally CPU intensive and don’t respond well to time critical demands. it may just be the delay due to windows USB/USB2 drivers!

Methinks Update with M$ USB2 update patch.
