Basic Disk


Basic Disk Drive is a traditional disk drive that is divided into one or more partitions, which contains basic volumes (partitions on a basic disk) such as primary partition, logical drive, and any extended partitions for efficient data organizing. On a basic disk, each partition is considered as an isolated unit and one cannot share or spilt data with other partitions.

Basic disks support IEEE (Institute of Electrical and Electronics Engineers) 1394 disks, clustered disks, and universal serial bus (USB) removable drives. These disks can be accessed by all versions of Windows, MS-DOS, and Windows NT. Also before using a basic disk, it must have a disk signature and should be formatted with either the File Allocation Table (FAT) or NT file system (NTFS) file systems.

Task that can be performed on Basic disk are as follows:

  • Create and delete primary and extended partitions
  • Create and delete the logical drives within an extended partition
  • Format the partitions and mark them as active
  • Repair failed legacy FT volumes such as mirror sets or stripe sets with parity

Number of Partitions created on basic disks:

In general, basic disks can have either four primary partitions per disk or three primary partitions and one extended partition with multiple (up to 128) logical drives.  However, the total number of partitions that can be created on a basic disk depends on the disk's partition style:

  • Master boot record (MBR) disks: On MBR disks, one can create up to four primary partitions, or three primary partitions and one extended partition. Within the extended partition, you can have unlimited logical drives.
  • GUID partition table (GPT) disks: On these types of disks one can create up to 128 primary partitions. This is because GPT disks are not limited to contain four partitions and one need not create extended partitions or logical drives.
  • To add more space to existing primary partitions and logical drives, extend the volume using the extend command in DiskPart.

Limitations of Basic disk

Basic disks cannot be used to create any kind of multiple volume sets, FT volumes or striped, mirror, RAID-5 sets etc. and they do not support the more advanced functions of Disk Management. To get these functions, one has to convert the Basic disk to dynamic disks.
