Hi there.
I have a small question regarding libata.
Using the plain IDE subsystem the Host Protected Area of a given HD is
disabled and this gives me more room for my files:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
hda: Host Protected Area detected.
current capacity is 156299375 sectors (80025 MB)
native capacity is 156301488 sectors (80026 MB)
hda: Host Protected Area disabled.
hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=65535/16/63
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
What is the current status with libata for PATA devices?
Regards, Rogério Brito.

You can choose to ignore it with libata.

Some clarification here: do you mean with ignore_hpa=1 here?
>From a quick reading of the code in libata-core.c, it seems that the
code tries to disable hpa, if possible. Is that correct?
I now regret having partitioned an HD under a 2.4 kernel. :-( I'm
wasting 10MiB according to bc. :-(
I wish that USB enclosures would also allow things like hpa to be
disabled.
Thank you very much for your help, Rogério Brito.
