Here are some:

The in <linux/hdreg.h> say this about 330:

...
/* 0x330 is reserved - used to be HDIO_GETGEO_BIG */
...

So it's HDIO_GETGEO_BIG, which doesn't exist in newer kernels.
I wonder when that got removed?  Minor userspace breakage there.

hdparm issues it first as a backward-compatibility thing,
before falling back to the even-more obsolete HDIO_GETGEO,
which curiously enough is still in modern kernels.

Cheers
