How do you fix the disk check could not be performed?
According to the possible reasons, this part lists the corresponding solutions for you.
Fix 1. Check the connection

Fix 2. Change drive letter and paths via Disk Management
Every hard drive plugged into your Windows computer will be assigned a specific drive letter of the alphabet because drive letter assignment is a process of assigning alphabetical IDs to volumes.
Without a drive letter, you’re likely to receive this error message: the disk check could not be performed because Windows cannot access the disk. In this case, you can assign a new drive letter to this drive via Disk Management because this Windows system tool is designed to execute varied advanced storage tasks easily.
