Weird problem with SATA+UDF

Software & Apps
#1

Hello, long time lurker here.

I have an LH-20A1S under win2k on an M2N32-WS Pro m/b. I’ve written a UDF disk with nero 6.6.1.5 (one of the files >2GB). This is the first time I’ve had to write a UDF disk. The disk wrote fine at 8x, but the LH-20A1S initially refused to read it back - windows complained “incorrect function”.

The disk is readable in four other DVD drives (two ATAPI lite-ons, a laptop teac and a laptop matsushita), and I can check the >2GB file md5sum to know the file is written correctly. Having suspected a problem with the LH-20A1S, I connected one of the ATAPI lite-ons, an LDW-851S to check the system, and found that if I load the UDF disk in the LDW-851S first I can then read it with the LH-20A1S as well, until I reboot.

I’ve also played with the roxio udfreader (v1.0.3) having read some old posts here. With that installed I can read the UDF disk in the LH-20A1S, but the md5 checksum of the >2GB file now doesnt match the stored value. It’s possible this is a 32-bit problem in the the udfreader. So far I’ve not tried the v7 update.

What I suspect is that windows is not attaching the UDFS functions until the ATAPI drive is accessed. I’ve not got any system ASPI installed, just nero’s, so perhaps there’s no SATA -> UDFS link present.

I have no other ATAPI devices in the system (it’s all SCSI). I really dont want to move away from win2k (xp: urgh), and I’d prefer to avoid the 3rd-party roxio fix since when win2k’s UDFS is active it works fine.

Any suggestions?

edit:

installed ASPI 4.60, no effect.

Have you tried different SATA controller drivers?

#3

Not something I’d considered, actually. I’ll look into it. Being nvidia maybe there’ll be an update, although the reason I’d not considered it is because I think the problem’s in the next layer up (then again, this is windows).

Thanks.

Also, many motherboards have an option to use PATA emulation for SATA … might make win2K use a standard PATA IDE driver, rather than anything special :wink:

Hi i have a similar problem…

I just bought a new LH-20A1S but i’m having problems with it, it doesn’t read any CD nor DVD, i updgraded the firmware to the latest version published on liteon’s page but it still doesn’t work; I wonder if there could be some incompatibility with my motherboard i guess the SATA ports are version I. What else do you think the problem could be? windows Drivers.

At this moment i’ve tried with almost 5 different firmwares…

Are your SATA ports part of the chipset, or an add-on chip to the motherboards guts?

Some early “add-on” sata controllers were only suitable for HDD’s.

#7

The SATA ports are part of the chipset, i think i have a defective DVD unit because i can upgrade the firmware using the SATA ports so there seems to be communication between the drive and the MB, when i insert the disc it tries to read it but windows says there’s no disc int the drive… :frowning:

Uninstall roxio -> Use the roxio install disc to start a fire.

Format the PC & reinstall windows. No roxio.

No seriously, see if you can uninstall the roxio packet writing software using change/remove in the software control panel. If you can’t, uninstall roxio & reboot.

And download imgburn. It’s more reliable than Roxio.

I have already formatted my pc and the problem continues.
I don’t think the problem is the burning software because i use both nero and roxio with another LG DVD without problems, this is my first Lite-on unit and i’m getting dissapointed with the brand :(.

As i said i cant’ even see the content’s of cd’s or dvd’s.

Does the drive work in a different PC?

Is the other drive SATA? or standard IDE?

#11

Nope, the drive doesn’t work on other pc.

i finally got a replacement, same brand, and model and it’s working fine. Don’t know what was the problem with the old one.

End of history :smiley:

update: installed nForce 9.16 drivers - no difference.

Does the drive work in a different PC?
If not RMA the drive.
