Nowadays, many notebooks (including tablets) no matter how big the hard disk is, but the manufacturer only leaves us a C drive, yes, a C drive with 500GB or even 1TB! In the event of a system failure, data on the entire hard disk will be compromised. So, is there a good way to cut a huge C disk into more partitions? Seeing this, it is estimated that many children's shoes will think of professional tools such as “Partition Assistant” or re-partition when installing the system. In fact, there is no technical content to cut the C disk, and no third-party programs are used at all. Windows 7 or higher has its own disk partitioning function. Take Windows 7 as an example. Right click on the computer and click on the “Manage” menu. In the list on the left side of the Computer Management window, select “Disk Management” and the current hard disk will be listed in the form of a graphic on the right side of the window. The partition status. For example, Xiaobian's notebook defaults to three partitions, including “Lenovo_Recovery” (for partitions that store one-click restore mirror backups, don't delete or destroy them, otherwise one-click restore will disappear), “SYSTEM_DRV”” Store the partition of the system and driver files, do not touch), and the C drive with a capacity of up to 454.82GB "Windows7_OS" is the object of our cutting. Right click on the C drive and select “ldquo volume” in the pop-up menu. The system will automatically calculate the compressible space later. The specific information will be listed in the pop-up “Compression C” window. The small notebook hard drive current C drive capacity is about 460GB, the system allows me to compress (cut) up to 218GB capacity for the establishment of D drive, E drive and other partitions, in short, the minimum capacity of the C drive will be limited to 247GB. The space compressed from the C drive will be named after the partition that is “unallocated”. Right click on the partition and click “New Simple Volume”. According to the system prompt, this space can be freely divided into D drive and E drive. ...and multiple hard disk partitions. Careful children's shoes may have been discovered, for the sake of this "compressed volume" function can only let us compress the C disk about half of the space? The 247GB C drive is still a waste! The reason is that this notebook has installed a lot of software before using this function, the allocation of hard disk sectors is disrupted, so the problem of limited compression space of C disk will occur. If you want to use the C drive as much as possible, you can use the "compressed volume" function in the first time when you find that the notebook partition is unreasonable. Do not install any programs during this time.
