1. What is it?

A plugin to indicate the status of the IBM Hard Drive Active
Protection System, or HDAPS.

2. Requirements

As of Linux kernel 2.6.28, a kernel patch is no longer required to
support the HDAPS functionality. As a result, this plugin will only
(officially) support kernels newer than 2.6.28.

It will also only (officially) support the hdaps module provided
by the tp_smapi project. The tp_smapi module is currently recommended
by the hdaps devs, so you should be using it. In the future, the
in-tree module will probably be supported as well.

Finally, you'll need to be running hdapsd (HDAPS daemon) if you'd like
the plugin to do anything. The HDAPS daemon is what updates sysfs with
the readings from the hdaps module. Get it here:

3. Installation

I think it builds like most XFCE panel plugins. Run './autogen.sh' in
the project directory, and hopefully it will configure itself. If it
does, run 'make'. With any luck, you will have an xfce-hdaps
executable in your panel-plugin directory.

Now, there should also be an xfce4-hdaps.desktop file in the
panel-plugin directory. You need to copy this to the directory where
XFCE keeps all of those things. For example, the system-wide location
on Gentoo is /usr/share/xfce4/panel-plugins/.

Finally, modify the X-XFCE-Exec parameter in the desktop file to
reflect the real location of your xfce4-hdaps binary. You should now
be able to add the plugin to your panel.


4. Settings

4a. Poll Frequency

This is the frequency with which the plugin checks the status of
HDAPS. If you set it to 500ms (the default), it will check every half
second and update the icon according to what it finds.

4b. Device Name

The name of the device whose HDAPS status you wish to monitor. This
will almost certainly be a hard drive, and will most likely be "sda".
With any luck, the plugin will auto-detect the supported devices on
your system. If you have more than one supported device, you will
need to select it on the configuration dialog.
