Final answer:
To run a disk check on a write-protected drive, disable the write protection via a physical switch or system settings. Once write protection is removed, use 'chkdsk' on Windows or Disk Utility on Mac to run the check. If write protection can't be removed, a disk check cannot be performed.
Step-by-step explanation:
To run a disk check on a write-protected drive, you will first need to disable the write protection. This can typically be done by adjusting the physical switch on the side of the drive if it's an SD card or USB thumb drive. If there's no physical switch, or if you're working with an internal hard drive, you might need to adjust settings within your operating system to remove write protection. Once the disk is no longer write-protected, you can run the disk check utility.
On Windows, open the Command Prompt as an administrator and type chkdsk E: /f (replace 'E' with the correct drive letter). On a Mac, you can use the Disk Utility program to run a disk check. If the disk is still write-protected and you cannot change this status, you will not be able to perform a disk check because the tool needs to make changes to the file system which is not possible on a write-protected disk.
