Yes, I had found that out from other posts on the list. My
"cryptic" aside was just a commentary on how counter-intuitive
it is.
Also, the numbers just don't match up with the media I have. I
had to use trial and error. The media I burned has:
Write Speed #0: 8.0x1385=11080KB/s
Write Speed #1: 6.0x1385=8310KB/s
Write Speed #2: 4.0x1385=5540KB/s
Or in the speed descriptor section:
Speed Descriptor#0: 00/1466335 R@6.3x1385=8672KB/s W@8.0x1385=11080KB/s
Speed Descriptor#1: 00/1466335 R@6.3x1385=8672KB/s W@6.0x1385=8310KB/s
Speed Descriptor#2: 00/1466335 R@6.3x1385=8672KB/s W@4.0x1385=5540KB/s
In no case should speed=1 match to 4x, or speed=2 match to 6x, unless we
are counting in speed-order, not listing or number order. No speed setting
(or setting speed=3) would then give 8x? The manual page is not really
helpful on this issue at all.
Does anyone have any idea if there is a patch in the pipeline to correct
this 8x issue if it is ide-scsi at fault? Is there a work around involving
using hdparm to set a lower DMA mode?
