Go to the C: prompt and type CHKDESK
You can use the chkdsk command with the /f or /r switch in a command prompt window to check and fix errors on a disk without requiring a restart, as long as the drive is not the system drive. For example, you can run chkdsk D: /f to check and fix errors on the D: drive. However, if you attempt to run it on the system drive (usually C:), you will be prompted to schedule the check for the next system restart.
The check disk command that does not require a restart to run is chkdsk with the /f option, executed from the command prompt. For example, you can run chkdsk C: /f to check and fix errors on the C: drive while the operating system is running. However, if the drive is in use, some repairs may not be possible until a restart occurs. To ensure a thorough check, it's often recommended to run chkdsk after a reboot.
To switch from drive A to drive C in a command prompt, you simply type C: and press Enter. This command changes the current working drive to drive C. If you need to switch back to drive A, you would type A: and press Enter.
Rita can use the built-in disk checking tool called "Check Disk" (chkdsk) on Windows or "Disk Utility" on macOS. On Windows, she can run chkdsk by opening Command Prompt and typing chkdsk C: /f, replacing "C:" with the appropriate drive letter. On macOS, she can open Disk Utility, select the drive, and click on "First Aid" to check for errors and repair the disk.

There are two ways to scan a hard drive for errors: the normal way or the old-fashioned way. The normal way: Go to My Computer (it might be called just Computer if you've got Windows Vista or 7) and right-click the drive you want to scan. Click Properties in the drop-down menu and then go to the Tools tab. There should be a button labeled "Check Now". You can click this to open the Check Disk utility. The old-fashioned way: Click Start, Programs or All Programs, depending on your OS, then Accessories, Command Prompt. In the command prompt, type in chkdsk c: and press enter. If you don't want to scan your C drive, replace the c with the drive letter that you want to scan. If that doesn't work, try replacing chkdsk with scandisk. If the scan finds errors, try the same thing, only add -f after the c:, for fix errors.
depends on the OS, but for most it is : defrag <DRIVE> example: defrag c:
When in Command(prompt) [Cmd] type: MD C:\Data <enter> It's as simple as that! Note: You must have the permission to create folders on C-drive..
Defrag c:
