Help: Running DVD-R burner on USB 2.0 ext. case

[pakman]

Hi,

I just bought a USB 2.0 external case for my burner LG GMA-4020B. I am having a dang time getting to work properly. First off, it is connected to my Epox 8rda+ mobo (nforce2 chipset) thru its onboard USB2.0 ports. I am running winxp pro sp1 with the appropriate usb drivers installed. My ext. hdd via usb2.0 works without a hitch. However, when I install the DVD burner, DVD movie playback stutters, music CD's skip and stutter, and when I run a DVD movie disk thru DVDSpeed, I get a read error. Same thing when I tried installing an extra DVD-rom player in the same enclosure. Winxp recognizes the drive properly, but...

Firmware's are all updated, winxp usb drivers are set properly, mobo bios updated and settings correct. I have done various tests and think I have narrowed it down to the onboard USB chip on motherboard.

Does anyone know what could be the problem? I have the drive set as master (tried slave and cable select as well but get same problem). Listening to the drive, its seems it is reading in bursts. The drive itself is not the problem as I can run it without a hitch on IDE.

Is there something about USB2.0/winxp that doesn't like DVD players/burners? Should I just give up and go with firewire (mobo has both firewire and usb2.0 ports). Or is it something particular to my motherboard.

I run mine in an external firewire case and it works perfectly. The only issue I have is Ulead MovieFactory SE can't burn to it, but I just burn the files with RecordNowMax....

I have some usb2.0 enclosures with DVDRW, HDDs or CDRWs. No problems at all, but I do not use WinXPee but win2ksp2.

Can record DVDs no problem, all works.

dragonong, since I posted that I found out my onboard usb2.0 (mobo epox 8rda+) was faulty. I ended up swapping usb2.0 for firewire external enclosures and haven't had any problems since. After the fact, I found I was having problems with a usb2.0 scanner crapping out as well. ended up buying a separate usb2.0 card to cure the problem.
