Created attachment 140248 [details] Partition properties SUMMARY Show unusable disk space reserved for reserved blocks, inode blocks in partition properties window of KDE Partition Manager for applicable filesystems like ext4 etc. On my PC for /dev/sda2 ext4 partition of 867.39 GiB, the reserved block count is "11368998*4096 bytes= 46567415808 bytes= 43.3693 gibibytes", inode count is "56852480*256 bytes=14554234880 bytes= 13.5547 gibibytes" which is lot of disk space. If above unusable disk space is shown in properties of a specific partition, then users can know where the disk space is utilized & can atleast modify the reserved block count, also when reinstalling the OS. New users can find this feature helpful. Also the partition properties of /dev/sda2 in KDE Partition Manager shows available disk space as 68.46 GiB, which includes reserved block usage etc, but actual usable free disk space is 10.4 GiB. Please see the attached screenshot. I am not sure everything above is correct. EXPECTED RESULT Show disk space utilized by Reserved blocks, Inode blocks, Journal blocks etc. or show it as filesystem reserved disk space in partition properties of KDE Partition Manager.
