Hi

I have used all patches above but i can't get it to work.

When i add it to the desktop i had only a small black dot.

Any ideas?

Try this one:

It looks way better and it works out of the box.

I think the following might be better, the only change to above is one line commented out, although I could not yet fully test this.

void AppletHdaps::init()
{
//Plasma::Svg* m_svg;
m_svg = new Plasma::Svg(this);
m_svg->setImagePath("widgets/drive-harddisk-running");
m_svg->setContainsMultipleImages( false );
updateGeometry();

searchDevices();

connect(m_pTimer, SIGNAL(timeout()), this, SLOT(doSomething()));
m_pTimer->start(250);
}

You guys who added the fixes, do you mind if I commit this to KDE's SVN in playground?

I use this fix to run the applet successfully, so as far as I see it works.

For 4.2 you also need this patch, because Plasma is part of KDE now:

This applet has the problem as khdapsmonitor for KDE3:

As you can see you need to change /queue/protect -> /device/unload_heads

I tried all patches here, but it always just shows a green arrow. I have KDE4.2 and kernel-2.6.28.

I try
# echo -1 > /sys/block/sda/device/unload_heads
and now it works for me.

Unfortunately this applet crashes Plasma, when I try to add it. KDE is 4.1, distro is openSUSE 11.0.
Any suggestions?
Btw. I've applied the patch, suggested here to get it compiled.

I had the same problem, just change the function void AppletHdaps::init() with this:

void AppletHdaps::init()
{
m_svg = new Plasma::Svg("widgets/drive-harddisk-running", this);
m_svg->setContentType(Plasma::Svg::SingleImage);

searchDevices();

connect(m_pTimer, SIGNAL(timeout()), this, SLOT(doSomething()));
m_pTimer->start(250);
}

Now it should compile. I sent the patch to the developer but he didn't answer.

Good luck :)

I'm sorry, I think I posted the original code :P

This is what I have:

void AppletHdaps::init()
{
Plasma::Svg* m_svg;
m_svg = new Plasma::Svg(this);
m_svg->setImagePath("widgets/drive-harddisk-running");
m_svg->setContainsMultipleImages( false );
updateGeometry();

searchDevices();

connect(m_pTimer, SIGNAL(timeout()), this, SLOT(doSomething()));
m_pTimer->start(250);
}

One of those should work :P

BTW, I'm using KDE4.1
