I am a new Manjaro user, my 1TB hard disk is showing two overlapped partitions, its shows two more partitions at the end that I don't recognize. I can't delete it using KDE partition manager. How do I fix it? thanks.

Partition 4 is extended so its alignment does not matter in practice, some partitioners do that and it can be ignored.

However the partition sdb6 seems to be out of bounds (starts at 3.18TB on a 1TB disk) and the graphical partitioner seems to be confounded by it (shows 1.98TiB unallocated space on a 931.51GiB drive, which is not possible).

Now the question is, how did this partition come about and what kind of data would you expect to find there? Sometimes there are programs that do shenanigans with the partition table (to hide partitions or map filesystem files as partitions) but I'm not sure about the purpose in this context.

It does show /dev/sdb6 as being mounted to /run though. Not sure what's happening there.

Double check cat /proc/mounts (what's mounted where) and head /sys/block/sdb/sdb*/{start,size} (partitions as the linux kernel sees it).

  • I was just checking out the KDE partition manager. I am not fully sure of what I did but after that, the 1.98 TiB unallocated showed up (they were not present initially). I have data in other partition but don't think there is anything in the unallocated partition. Commented Oct 22, 2021 at 4:53
  • Hope this is what you meant. let me know if anything more is needed. Thanks for responding. Commented Oct 22, 2021 at 5:01
  • Also, GParted is showing: "cant have overlapping partitions", "cant have partitions outside disk". and i believe the sda6 mounting to /run is the swap partition that i created for manjaro. Commented Oct 22, 2021 at 5:12
