Delete Partitions with parted

Before deleting a partition, back up your data. All data is automatically deleted when a partition is deleted.

run the d command in the fdisk command-line utility.

Verify Partition Deletion

Reload the partition table to verify that the partition has been deleted.

run the p command.

The terminal prints out the partition structure of the disk selected in Step 2.

Save Changes and Quit

run the w command to write and save changes made to the disk.

Formatting Disk Partition with ext4 File System

Format a disk partition with the ext4 file system using the following command:

sudo mkfs -t ext4 /dev/sdb1

Next, verify the file system change using the command:

lsblk -f

Check disk performance

hdparm -Ttv /dev/sdb1

out:

/dev/sdb1:
 multcount     =  0 (off)

 Timing cached reads:   12072 MB in  2.00 seconds = 6041.48 MB/sec
 Timing buffered disk reads: 1214 MB in  3.04 seconds = 398.73 MB/sec
