So the RAID in my laptop crashed…

by on Feb.01, 2011, under Projects, quickhack

I told you about the brand new RAID in my laptop. Well… Yesterday it didn’t boot anymore. After some time of trial and error I figured out that the ext4 filesystem was broken. Trying to fix it with fsck.ext4 resulted in… Kernel Panic! So I tried dd‘ing it to my server so I could work on the copies. After about 250GB… Kernel Panic! Then I tried mounting the filesystem Read-Only and pulling out my files. It worked! But after about 200MB… Kernel Panic! So I had no Idea what to do now. How can dd lead to a Kernel Panic? Something must be wrong with my laptop hardware.

To fix this, I decided to attach the drives directly to my server. One of them is now mounted in an external case, just without the case. The other one is directly attached to one of the controllers in my server machine. There was no spare power plug, so I just took one from my gaming PC. How does this look? Kind of odd. See for yourself:

I am using ddrescue to pull of images from the disks. The speed is kind of slow but that is better then losing my data.

I’ll now try to assemble and mount the RAID read-only while it is copying… Wish me luck!


I could actually assemble the raid and mount the ext4 partition on it. I am now copying my important files. I hope it runs through!


It worked! I got my files.

OH and I forgot to show you that:

One thing I learned from this is: No raid and no fucking ext4 in a laptop!

Recent changes to my laptop

I ordered a caddy that replaces my cdrom-drive and allows me to add a second hard disk to my laptop a few weeks ago. Then I bought a 500gb hdd and put everything in my laptop. The cool thing is that I now have a raid. The caddy looks like this:

I am getting about 120mb/s reading speed with my brand new raid. Some applications start notably faster now, however, I don’t really feel the software is faster when already running. After all it is just about huge guts.

New Blog

by on Jan.14, 2011, under Random

Hello there, fellas!

I finally decided to create a Blog. I also decided to keep it in english. I actually don’t really know why, but I did. It was like a 5-minute-thing anyways and now I just have it.

I’ll be blogging lots of different things, mostly about projects or other stuff I am doing, but it almost certainly won’t happen on a regular basis.

Now I’m just going to be happy about the new raid in my notebook while tweaking wordpress to my likings.

Have fun with the internet and remember not to overdo it!
