| Possible Reason | Explanation | Solution |
|---|---|---|

| 2. Uninitialized/Unformatted Drive | New drives must be initialized and formatted before use. | Initialize the disk to MBR or GPT and format (NTFS recommended). |
| 3. Missing/Conflicting Drive Letter | Drive lacks a letter or conflicts with existing assignments. | Assign a unique drive letter via Disk Management > "Change Drive Letter and Paths". |
| 4. Unsupported File System | Optimize Drives skips exFAT or non-NTFS/FAT drives. | Reformat the drive to NTFS (back up data first). |
| 5. Drive Errors or Corruption | File system errors or bad sectors on the hard drive prevent recognition. | Run chkdsk X: /f (replace X with the drive letter) in Command Prompt. |
| 6. Outdated/Corrupt Drivers | Drivers are deleted, missing or outdated. | Update drivers via Device Manager or the manufacturer’s website. |
| 7. Failing Drive | Physical damage or impending failure causes detection issues. | Replace a new disk. If you want to reserve all the data, you can clone the hard drive first. |
