hdparm woes

Checking hdparm settings on my drive gives this...

/dev/sda1:
IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 14593/255/63, sectors = 12691287, start = 63

Obviously this is subpar. Here is my drive.

The error.

root@me:/home/chris# hdparm -qm8 -qu1 -qc1 -qd1 /dev/sda1
HDIO_SET_32BIT failed: Invalid argument
HDIO_SET_MULTCOUNT failed: Inappropriate ioctl for device
HDIO_SET_UNMASKINTR failed: Inappropriate ioctl for device

or

root@me:/home/chris# hdparm -c3 -m16 /dev/sda1

/dev/sda1:

IO_support = 0 (default 16-bit)

Is my drive unsettable?
