libata is not specific to Serial ATA. It works for Parallel ATA (a.k.a. IDE) as well. Certain SATA controllers such as Promise and SiS include PATA ports on their SATA controllers.
libata has gained full support for PATA, including older chipsets and devices with buggy/problematic designs. Alan Cox has done a lot of work on this. PATA is be fully supported, alongside SATA. libata PATA drivers exist for almost all PATA chipsets.
libata PATA drivers will not be turned on by default for a long time, to avoid conflicts with CONFIG_IDE (the traditional IDE driver).

I got this while I was trying
$ sudo hdparm -c1 /dev/sda
/dev/sda:
setting 32-bit IO_support flag to 1
HDIO_SET_32BIT failed: Invalid argument
IO_support = 0 (default)
This is how my drive stacks up . This is a seagate 160 GiB
$ sudo hdparm -i /dev/sda

Hi all,
Leann Ogasawara
Is there possibility of some of the problem might be due to the libata driver
