This pair just dont get on at all, if i stick the nd-2500 dvd-rom on the same channel my 52246s stutters whilst reading and refuses to burn, the 52246s is running at Ultra DMA mode 2 and the ND-2500 at Multi-World DMA mode 2, ive tried forceing the ND-2500 to run in PIO mode but it makes no difference to the 52246s arggh i want them both in this system!, i dont know how my HDD will take to having the DVD-ROM paired on the same channel but ill try it later, also i am using 80 wire cables and i have tried swapping the drives over from master to slave etc, heres the system specs
