  • Most of the people just work with the C: aka the main drive, even if the total capacity of the hard disk is 500 GB or even more.
  • This is not the best way to set up a laptop.
  • Even if your new laptop has a small hard disk – read 250GB – you should ideally partition it as soon as you can.

This will help you in two ways: – Partitioning the C drive will separate the primary drive (aka C) that has the operating system and application from the other drive (it could be D or any other available letter that you choose). – Two drives in the system will help you manage your data better.

  2. Just remember that the size can’t be lower than what the tool has suggested.
  3. We suggest that you set around 120 to 200 GB for the C drive.
  4. Even if you install a lot of heavy games, it would be sufficient.

  • Once again, specify the size of the volume.
  • If you just want one more virtual drive, select all available space.
  • If you want more than one extra drive, you can decide to divide the available storage into multiple volumes.
