Why Do You Need to Partition or Repartition a Hard Drive
The disk of most computers or a new hard drive only has a single partition by default. For hard disks without the default partition, you should create partitions and format them by yourself. Otherwise, you can’t use the disk to store data.

If there’s something wrong with the index file of the partition, your computer won’t boot. Even though it boots up with the help of a recovery disc or external drive, you still can’t access the rest of the data. Hence, it is vital to partition a new hard disk.
