Riesim ten isty problem:
Kód: [Vybrat]
$ sudo hdparm -d 1 /dev/sda

/dev/sda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Inappropriate ioctl for device


$ sudo hdparm /dev/sda

/dev/sda:
 IO_support   =  0 (default 16-bit)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 14593/255/63, sectors = 234441648, start = 0Sice sa tvari ze ho zapina, ale nic sa nestane.
Dmesg je cisty.

No co se tyce UDMA SATA a PATA, ono je to jeste malinko jinak.
