The 100% does not refer to use of disk space, it represents disk access. Any time you do disk-intensive operations (actively reading and writing), you can briefly hit the limits of the drive's capacity to access contents or move data. That's normal. It works as fast as it can until the job is done and then the utilization goes back down. Those MB/s ...

@wurtel's information fixed it. Output of `lsof -n | grep deleted` ================================== rsyslogd 943 root 1w REG 253,0 20649662640 122793 /var/log/messages.20140731 (deleted). 20649662640b translates to 20.64G. Restarting rsyslog fixe the issue! Thank you everyone!!

If you delete (unlink) a file which is kept open by a process, you'll see the usage disappearing from du, but still in use by df. As soon as the last process closes the file (which happens latest when that process exits), the space used by the file will be deallocated and available in df as well.

Linux keeps a buffer space, that can only be used by root. Running sudo tune2fs -l /dev/sda1 will show the number of reserved blocks in its output. To turn off reserved blocks altogether just use the following command: sudo tune2fs -m 0 /dev/sda1

According to the man page, zerofree won't work on read+write (rw) mounted filesystems (/ is typically mounted as rw); it requires the volume to be unmounted or mounted as read-only (ro). Two options are available: Create a "zerofree dedicated VM", where you can dedicate to zerofree other VM images; then attach the disk to that vm but do not mount or boot ...

You need some more space to work with. In the case of your qqq file you can append to it with dd. Once you have some more free space to work with rebuild the superblock of the filesystem which will detect the block count of the filesystem is wrong. With the new superblock written you can rebuild the tree. Assuming your file is still unmounted: $ dd ...

Audio CDs do not have a filesystem, that is why explorer will not show the tracks. Instead you should install a music cd ripper, like CDex (http://sourceforge.net/projects/cdexos/) which can display the size of the audio tracks.

And what have you expected? :) It will show zero free space because you can't write files to an audio CD. Similarly, you can't delete files from it, or move them to another location on the CD. As an audio CD has a different format from a Data disk, you can't see in Windows Explorer its capacity:

Try emptying your Trash - as files in there still take up space.

That is a file that is generated by the Microsoft Windows Resource Checker (SFC.exe). No, it should not be that large. The CBS.persist.log should be generated when the CBS gets to be around 50 meg in size. CBS.log should be copied to cbs.persist.log and a new cbs.log file should be started. You can try compressing the file: If you right click on the ...

Since turning off the updates is not a wise choice, my solution is to reinstall the whole Office from time to time using an installer that already includes all of the updates. A few days ago I have freed up 5 GB this way (my previous Office installation was in November 2013). Note: if you cannot get such an installer you can always slipstream your own ...

If you perform backups of your iPhone or iPad regularly, OSX keeps these handy and doesn't overwrite them so they start to clog things up once you're into "space management mode". If you are an iDevice user, check: ~/Library/Application Support/MobileSync/Backup
