My laptop started acting weird. All net tabs in Chromium immediately crashed. So, I tried to start midori instead, but nothing happened. Trying to start it from a terminal, which happened to be open, gave some weird errors. It couldn’t even load the executable.
It seems, the hard disk went offline. (Windows would just have BSOD’d, Linux keeps running even without harddisk)
Looking at dmesg. I couldn’t |tail is, this would give a “bus error”, due the hard disk problem. So I had to get the entire log…. but I couldn’t save it to a file without running hard disk. Scrolling in the terminal window also stopped working, so I could only get the last few lines in the log, which were these lines

Now… what does this mean? Something wrong with the hard disk? the controller? or is this a bug in the kernel?
Besides, my battery is really starting to get bad. I don’t get it. One day it says ninety-something % capacity, and then a few days later is was fourty-something. and now it’s down to 36%. Why *suddenly*? Does it enter self-destruct mode after warranty expires?

That sucks!
The SMART status of the hard disk seems fine. I am keeping a USB stick mounted so I can try to store the full dmesg output, in case it happens again. But it hasn't.
Maybe the harddrive is overheated.
It is your laptop?
In that case, check if your cooling-pad is working properly. I expect you're using a cooling-pad with this hot weather, otherwise the harddrive is definitely overheated. My cooling-pad makes my harddrive over a 10 degrees colder (it's very close to it's maximum temperature when I don't use the cooling-pad).
Some years back I'd also got an overheated harddrive in a desktop computer. That was because two harddrives were mounted directly above each other. You should NEVER mount two harddrives directly above each other. ALWAYS leave some room between the harddrives so there's some air above each disk for cooling.
It could also be the data or power plug that came loose or a defect on the motherboard. Try the harddisk in a different machine.
Anyways, I hope you can fix it and your data is not permanently lost.
Good luck.
It is my laptop, and I don't have such a cooling pad you have. Never had any. If such a thing is necessary then, in my opinion, it's a design flaw in the laptop. It should not be allowed to overheat.
And in the time I had like 5 or 6 hard disks in my desktop machine, I had no choice then to use all possible mounting positions, so leaving a gap was not possible. And yes, it ran pretty hot. But always worked without a problem. (apart from a bad IDE cable, that is)
Besides, this is my university laptop. *If* it breaks down it's to them to fix it. And it has ran without a problem all week. So it was just a hickup.
Just saying. I don't bother about the temperature, as from my experience, temperature has never caused me any problems.
