I could be mistaken, but I've been firmly under the impression that setting most performance-related modes like 32-bit transfers and DMA is not necessary for SATA devices, since the host interface should take care of tuning to a much greater extent than was possible for legacy parallel ATA. I have a Western Digital Raptor connected to the SATA inteface on my Asus motherboard using the sata_via driver and "sudo hdparm -c 1 -d 1 /dev/sda" also fails for me, though performance is great: dparm measures almost 70MB/sec reading.
Of course, if you aren't able to use hdparm to set those values for a parallel ATA device (which may also be called /dev/sd? if it's provided by a libata driver), that's a completely different issue. -- S-ATA cannot be set to use DMA and 32-bit mode https://bugs.launchpad.net/bugs/174322 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
