попробуйте почитать man hdparm:

-d     Disable/enable the "using_dma" flag for this drive.  This option
               now  works  with  most combinations of drives and PCI 
interfaces
               which support DMA and which are known to the kernel IDE 
driver.
               It  is also a good idea to use the appropriate -X option 
in com-
               bination with -d1 to ensure that the drive itself is 
programmed
               for the correct DMA mode, although most BIOSs should do 
this for
               you at boot time.  Using DMA nearly always gives the 
best  per-
               formance, with fast I/O throughput and low CPU usage. 
But there
               are at least a few configurations of  chipsets  and 
drives  for
               which  DMA  does not make much of a difference, or may 
even slow
               things down (on really messed up hardware!).  Your 
mileage  may
               vary.

может это поможет, сам не пробовал/сталкивался.
