I’ve just had a Sony Optiarc ND-3570A dvd burner installed in my machine (Dell Precision 390) by the Dell support guy (machine still under warranty).
But now, it comes up in only PIO transfer mode, which slows the whole computer down to a crawl whenever the drive is being accessed. (Which is driving me nuts.)
I’ve found heaps of sites talking about Microsoft’s 6 fails/timeouts at a DMA transfer then the drive will be demoted to PIO only. I’ve uninstalled and reinstalled the drivers in Hardware manager and reset the Registry checksum for the device, and I do see the 6 errors in the System Event Viewer, and from that point on it’s PIO only.
The dell guy never had any specific installers for the burner, and I can’t find any on a Sony/optiarc/NEC site for it either.
I’ve updated my BIOS firmware - no difference.
According to Hardware Manager, the driver for the IDE channel is:
and for the Optiarc DVD±RW ND-3570A is
Seems quite odd that there’s no newer drivers since 8 years ago for a DVD burner…
Does anyone know if there’s a more recent driver that will enable DMA mode for this burner?
