Re: Does the linux kernel contain support for ATA Security feature set?

So when I do a hdparm --security-set-pass NULL /dev/sda
I get a
SECURITY_ERASE: Input/output error
This is with a kernel that doesn't have CONFIG_IDE_TASK_IOCTL=y defined
I'm also told that for SATA drives that's not necessary anyway. Is
that correct?
What should the response be for hdparm if CONFIG_IDE_TASK_IOCTL isn't
defined for a drive that needs it?
The drive is an Intel X-25M
HDDERASE won't work since I'm on a Mac.
I don't want to create a customized lived CD witth a new kernel unless
it's necessary.

So you're implying that it is possible to do a SECURE_ERASE using
hdparm then.
I don't know why but HDDERASE tool requires legacy IDE mode.

idea of
a any boot CD that I could boot and run a program that can issue a
SECURE_ERASE (SE) to the drive is only applicable to PC's.
Why is the lack of legacy IDE an issue? hdparm works fine with SATA
setups.
