I've found the solution but it's really stupid and some kind tricky. Background of problem The thing is that I have an backup system (Simple Backup) that runs in background and doesn't show it's presence, so I didn't know that it was running. The backup was suppose to store about 4-5 GB of data on an external drive pluged-in by USB. The thing is that I setup the backup directory on /media/Backup1 where the drive was firstly automounted. After a couple of plugins and outs' (where there could be some without dismount) the mounting directory changed to /media/Backup1_ then Backup1__ and so on, without my knowledge (the name of the shortcut remained the same).
Now the main thing When I was working I didn't know the backup was working (in a kind this means that this is a good backup system :]), I just saw a filling up disk space. Then I saw in Baobab that only 'windows' and 'media' are big. Because this external USB drive is about 500GB amount of 110GB was enough for him and too much for my Linux partition. I didn't check that part of this media directory was stored on my local drive and not on USB. So this was the problem - summary of linux mounting system + background jobs without notices + my false conviction.
