projects are lost in eclipse workspace after restart - eclipse

I need some help!
I am using eclipse 3.7 and mylyn 3.6.2 with JIRA connector 3.0.2
Sometimes after restart eclipse forgets all the projects in the workspace. Workspace is not totally recreated all the mylyn connections, and java working sets are present, but all the projects are gone.
So I need to re-import them each time this happens.
I am blaming mylyn, because this never happened before I started using it.
And in log file I see that it has some problems on start:

The problem was with my HDD. After formatting everything works fine.

How to install the RED Robot Framework Editor plug-in manually into Eclipse?

Our corporate firewall is not allowing traffic directly towards SourceForge so we were supplied the plug-in JAR file through a fileshare. We have used the following download link.
We found several instructions to install plug-ins manually but we were not able to. It looks like this JAR file is not suitable for manual installation? Or what are the steps we need to take?

Eclipse Indigo Crashes Very Unstable

I am using Ubuntu 14.04 with JRE 8. I am a newbie tying to learn javascript, but I have the rather annoying problem that my Eclipse Indigo SR2 x86_64 installation crashes every few moments.
Solutions I've tried:
Purging / reinstalling Java (sometimes after a crash I get an error message stating that Java crashed, but most times Eclipse simply crashes and no message.)
reinstalling Eclipse
Adding " -Dorg.eclipse.swt.browser.DefaultType=mo­zilla " at the end of the eclipse.ini file (no change in crashing behavior)
Checked for updates
My error log says the following:

Startup with -clean option didn't work. Any idea on how to fix the .metadata directory?
Thanks in advance
I am not sure whether this error is related to your workspace or the STS installation. What happens if you select a different or fresh and clean workspace? Does that work?
If not, I would re-install a fresh copy of STS, since the error looks a bit like an incompatibility between different parts, maybe an incomplete update or something like that.
If starting STS with a different workspace works just fine, I woudl completely delete the .metadata directory of your workspace while STS is NOT running. Then restart STS (the workspace will be empty, but the projects are still around on dics since you deleted the .metadata directory only). Go to "Import Existing Projects into Workspace", select the workspace location in the upcoming dialog and re-import those existing projects into your workspace.

Can't export deployable features in Luna

I am trying to export a couple of deployable features in Luna, but I always get the error message below. I have two plug-in projects, a corresponding feature project for each and a category definition. With this set up Kepler exported the deployable features into a folder flawlessly, but with Luna there is always this message.
How can this be solved? Is there any other relevant information I can post?

This is a known issue with release 4.4.0 reported in Bug 438652. A fix was shipped with release 4.4.1, thus an update to Eclipse gets this functionality working again.

Programmatically installing plugins from Eclipse plugin: error processing mirrors URL

We've tried a couple of things, like setting in the pom.xml for tycho that we don't want to use mirrors, or giving it as a JVM argument, or simply setting the System property to not use mirrors. However, as far as I understood, this will only cancel out non-eclipse.org sites and this is an eclipse.org site...
The updatesite to install from is: http://download.eclipse.org/modeling/emf/teneo/updates/2.0.0/interim/ (for Teneo).
What can I do to prevent this error from happening? To be clear: this doesn't prevent the code from running as it should. Teneo gets installed. I just don't want this kind of errors popping up in the Error Log.
Thanks for any tips.
