Don't put the "1" at the end of your device name.

The correct command is:

sudo hdparm -d 1 /dev/hda

HTH...

The command is drive based, not partition based..

"hdparm -d1 /dev/hda"

thanks it worked from 2mb/s to 11mb/s, however my hdd is meant to work with dma2, but is only compatible with the -d1 command

-d1 command is just the "ON" button for DMA. It does not specify the DMA/UMDA performance level.

See below for additional command line options regarding this program, especially the commentary next to the "-X" option:
