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 188.8.131.52 (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.
installed ASPI 4.60, no effect.
