Ok, the disk has a host protected area and now I'm telling libata to
disable it.
The error messages has disappeared.
But... Is it safe to do it? I've read somewhere that the BIOS and
other softwares may use that area.
On some systems. Its also used for different things on others (rounding
off disk sizes nicely, clipping to avoid bios limits etc)
Also, I remember that with the IDE driver I wasn't seeing that
messages, which means either: it was disabling it by default or
was just ignoring it.
Old IDE disables it by default, libata is more conservative. Personally I
think libata should disable it by default too but thats an argument to
have with Jeff
