I have recently purchaced a SATA DVD-R drive, its Pionner DVR 215D.
I have trouble burning DVD discs with it to more than x2.
I think the fault is with the onboard SATA of my motherboard, this Pioneer is too new for it.
My motherboard is kind of old, 3 years old in about, its the Gigabyte 8S648FX.
I had the same problem with a [B][B]Promise Ultra 133 TX2[/B][/B] and IDE DVD-R at the past, but it was just because that Promise does DMA just for Hard drives.
If anyone is familiar with this, the DVD-R is appearing at device manager as : SCSI CDrom Device.
The excact same was with the Promise Ultra 133 TX2.
SCSI CDrom Device was appearing after the device’s name on the DVD/CD-ROM at device manager. And yes it coulnd’t do DMA.
So, is it the sis 180 capabilities limited for DVD-R DMA, or is this possible?
Promise controllers are a NO GO with optical drives (few exceptions, but only with CD).
