This is not a Plextor problem, but I’m running out of places to turn to find a solution. “Saphire”, one of the pros at the VIA forum suggested I might get help here, so, I take liberty in posting this here.
I recently bought a PX-716A drive, and installed it as master on my secondary IDE channel. I have an AOpen DUW 1608/ARR DVD burner as slave on that channel. My pri channel has a Maxtor 120 G HD by itself. My HD runs along fine in UDMA on it’s channel, but the 2 optical drives are in Multi-Word Mode 2. Both drives are capable of UDMA. So, I put each of them, one at a time, on the pri channel as slave, and each immediately switched to UDMA. So, it’s not a drive problem. I checked my BIOS, and both IDE channels are set to “Auto” for Ultra DMA. I have reinstalled both IDE channels several times, put in the latest VIA chipset driver (18.104.22.1682 for VT8237 chipset), tried a new IDE cable all to no avail.
I have tried to get an answer from ECS, but I don’t think they know anything about the problem. The guys on the VIA forum have run out of ideas, so I turn to you in hopes that someone here may have seen this problem before, and found a solution.
ECS PT800CE-A mobo (latest BIOS 1.1E), 3.0 G P4 Processor in hyperthreading mode
Maxtor 120 G HD
1 G (2 X 512) DDR 400 RAM
NVidia FX5200 video card (8198 driver)
Soundblaster Live Value Sound card
2 optical drives as described above
If all else fails, I may have to ditch my ECS (El Cheapo System) mobo for something better.
Any help you can pass on would really be appreciated.
