Okay I had a problem with one drive burning dvd’s so I purchased another drive and it works great burning dvd’s by itself. Both drives work in UDMA mode 2 and 4 if they’re hooked up one at a time. The drive that came with my Dell system was setup as cable select.
When I hook both drives up, the new one as master, the old one as slave. The slave only has a 1x burning option (unfortunately i didn’t see whether it was in PIO or DMA mode at that time)
When the old drive is hooked up as master by itself only 1x burn option is available, hooked up as cable select all burn options are available.
So hooking both drives back up again the new drive as master and the old drive as cable select they both have all burn speeds available however the old drive hooked up as cable select and is in PIO mode. (new drive is in DMA mode)
I know if one drive is set as cable select they all should be, but I’m leery about changing my new drive to cable select since it works great setup as master and the old drive seems to work better setup as cable select.
Do I need to change both drives to cable select to get both drives to work in DMA mode? Both drives are setup on the primary IDE channel one in location 0 - the one that works at DMA and the other in location 1 which seems to only work in PIO mode.
