Questions about hdparm

[Douglas Phillipson]

hdparm doesn't seem to report, for SCSI drives, the asme stuff it does 
for IDE drives.  I'm specifically looking to see if DMA transfers are on 
or off.  I presume since I don't see a "using_dma" attribute that it 
doesn't apply to SCSI???

IDE:

/sbin/hdparm -vt /dev/hda

/dev/hda:
  multcount    = 16 (on)
  IO_support   =  1 (32-bit)
  unmaskirq    =  1 (on)
  using_dma    =  1 (on)
  keepsettings =  0 (off)
  readonly     =  0 (off)
  readahead    = 256 (on)
  geometry     = 65535/16/63, sectors = 156301488, start = 0
  Timing buffered disk reads:   96 MB in  3.00 seconds =  31.97 MB/sec


SCSI:

/sbin/hdparm -vt /dev/sda

/dev/sda:
  readonly     =  0 (off)
  geometry     = 4420/255/63, sectors = 71020544, start = 0
  Timing buffered disk reads:  64 MB in  1.43 seconds = 44.76 MB/sec
