I find:

:~ hdparm /dev/sda

/dev/sda:
 IO_support   = 0 (default 16-bit)
 HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
 readonly     = 0 (off)
 readhead     = 256 (on)
 geometry     = 48641/255/63, sectors = 781422768, start = 0

I would say yes, but there appears to be a problem with it on my 10.1
x86_64 2.6.18.8-345-default system.

As well you should be.  You are on linux, satisfy your curiosity.
There are literally thousands of ways beginning with google, man and
info, and the cl '<command> --help' functions.
