Hard Disk partitioning for Windows and Linux systems

In Windows, hard disks are expressed by disk 0 and Disk 1, indicating the first and second hard disks, and then partitioned on disk 0, drive letters, such as drive C and drive D, are used for partitioning ...... Wait. Generally, the drive letter is postponed from C to Z, But I tested it in Win7. The drive letter can be A, B, but I don't know if A or B can be used as the primary partition.

Next, let's talk about the Linux system. There are two types of Hard Disk representation in linux: the first type of IDE disk, represented by hd, hda, hdb, hdc ...... Indicates the first IDE hard disk and the second IDE hard disk ......, While hda1, hda2, hda3 ...... Indicates the first partition on the first hard disk, and the second partition on the first hard disk ......; The second type is SATA and SCSI disks, represented by sd, sda, sdb, sdc ...... Indicates the first hard disk, the second hard disk ......, Similarly, sda1, sda2, sda3 ...... It indicates the first partition of the first SATA hard disk and the second partition of the first hard disk .......

Partition mounting for windows and linux systems.

In windows, partitions are not used unless the system is used for partition ~ When all the 26 drive letters are used up, this creates a problem. Is there no way to use unused blank partitions? You can create a new folder in the allocated drive C or other disks and mount unallocated blank partitions to the folder. This allows you to use unallocated blank partitions. Subsequent read/write operations on this folder will be performed on the blank partitions attached to this folder, without occupying the storage space of other disks. (For details, right-click "disk management" and choose "Change drive and path"> "load blank NTFS file"> "Browse"> select a path> "OK"> "OK ". the system is Win7_x64 ))

In linux, there is only one drive letter, that is "/". All partitions in linux are mounted under the root directory "/", such as/boot,/bin,/etc ...... And so on.
