Drive Not Showing in Optimize Drives

Why need to defrag the PC disk?

As we all know, no matter how well-configured a computer is, it will slow down after a period of use. But maybe what you don't know is file fragmentation is one of the incentives.

In the beginning, the data on the hard drive is arranged in order. But when some programs are deleted and installed, some file fragments will inevitably appear on the computer. Since file fragments are scattered around, the disk will waste a lot of time searching for them when reading data, then your PC will be slow all of sudden.

In order to optimize their PC, many users try to defrag files with Defragment and Optimize Drives, but they meet the problem of hard drive not showing up in optimize drives. So in the following content, we will share 3 methods to solve it.

When the optimize drives are not available, you can take the following measures.

Solution 1. Use the chkdsk /f command of CMD

If you find that the target disk is not displayed in optimize drives, there may be an error with your hard disk. Thus, you can use the Command Prompt to check disk.

CHKDSK is a command-line tool, specially used to check the hard disk file system and repair a series of hard disk errors in the Windows system. You can also use it to check for bad sectors, fix blue screens, etc. Please follow the steps below.

Step 1. Press "Windows + R" simultaneously, then type "cmd" and press "Enter".

Open Run

Step 2. Type "chkdsk /?" to know the details in advance.
