Then I don't know why the HPA was disabled previously. It should not be
disabled by default as some BIOSes will overwrite data in the HPA in
some circumstances (possibly only on matched HDs). There is a
workaround for cases where an HD was partitioned while the HPA was
disabled: if a partition is found to extend into the HPA then it will
automatically be disabled.
You should be able to disable the HPA for this disk by following these
steps:
1. Create a file under /etc/modprobe.d containing the lines:
options ide_core nohpa=1.0
options libata ignore_hpa=1
2. Run 'update-initramfs -u -k 2.6.32-3-686'
3. Reboot
It is also possible to permanently disable the HPA using hdparm, but
that requires a custom kernel with CONFIG_IDE_TASK_IOCTL enabled.
