So basically i was messing around in Linux and i wiped the fileystem from a partition with wipefs and then decided to delete this partition (/dev/sda2) so i went on parted and deleted it.
After this i went to fdisk and created it again. I then went on to add a file system to this partition using sudo mkfs -t ext4 /dev/sda2 and this created a etx4 filesystem on the partition.
I then went onto fdisk again by typing sudo fdisk /dev/sda2 and then a message in red text came up, which is this:
Welcome to fdisk (util-linux 2.29.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device /dev/sda2 already contains a ext4 signature. The signature will be removed with a write command. Device does not contain a recognized partiton table. Create a new DOS disklabel with disk identifier 0x3a701490. Command (m for help): p Disk /dev/sda2: 46.6 GiB 50000297984 bytes, 976 Units: sectors of 1 * 512 bytes Sector size (logical/physical) : 512 bytes / 512 bytes I/O size (minimum optimal) 512 bytes / 512 bytes Disklabel type: dos Disk identifier 0x3a701490
** My question is, why does fdisk show that the disk has a previous ext4 signature even though i removed all signatures on the disk with wipefs**
Also why does it say that a partiton table is not recognised, it clearly says on the **Disklabel section that the partition table is a dos one**
