This is because an MBR disk can only support 4 primary partitions or 3 primary partitions and one extended partition with a number of logical drives on it. If you are running on an MBR disk, please check the number of partitions you have already had on the hard drive. What should you know before creating D drive?

✎ If one of the partitions is infected by viruses or crashed by malware, you just need to recover the corrupted one, your other partitions are still safe.Īfter considering all the reasons above, it's necessary and urgent to create D drive in Windows 11, 10, 8, 7.

✎ Different partitions storing different kinds of data may help you to manage them effectively, for instance, you can find what you need quickly next time. ✎ Too much data taking up the free space of the C drive (system disk) will slow down your PC. If you only have one partition with all data stored on it, you will lose all of them and can't restore them anymore. ✎ When you need to recover the system one day, the whole C drive will be formatted. However, according to users' feedback, no less than three partitions can give you the best experience: one is only for storing system files, one is used for downloads like applications or programs, and the others are created for your personal data.

That is to say, there is at least one partition on your disk if you don't manually create partitions before installing Windows 11, 10, 8, 7. If you install Windows operating system on it, Windows will generate C: drive to store the relevant files by default. When you purchase a new computer, the disk will be displayed as unallocated space which cannot be used directly before it's partitioned.
