I believe it should work with 2.4.0 or newer.
But some kernels have a buggy implementation of it.

That failure indicates that your drive is not using libata drivers.
USB/SD drives/drivers do not support this flag at all,
but drives using the ancient IDE drivers should work.

For drives using the ancient IDE drivers, you will need
to use a kernel configured with the CONFIG_IDE_TASK_IOCTL flag.
If you see the message above, then that means your kernel
was probably built without that configuration option selected.

Look in /proc/config.gz and see if the option shows up there,
or in "cat /boot/config-`uname -r`".  If you don't see it
in there, then the kernel would have to get rebuilt with
that config option to enable the feature.

Or just switch to the modern libata drivers for IDE/SATA drives.

Note also that hdparm has now been updated to version 8.4,
with some unrelated bug fixes.

Cheers
