Resolving Windows ERROR_SAME_DRIVE 143 (0x8F): A Comprehensive Guide

The ERROR_SAME_DRIVE 143 code indicates a failure when attempting to associate a drive with a directory on the same drive. This guide provides effective solutions to resolve this issue.

How to Resolve ERROR_SAME_DRIVE 143 (0x8F)

Step 1: Choose an Alternative Drive Letter

To avoid the ERROR_SAME_DRIVE conflict, ensure the drive letter you intend to use isn’t already in use by another path on the same drive.

Press the Windows key, type cmd in the search bar, then select “Run as administrator.”
Type the following command to check existing drive substitutions, and press Enter : subst F: C:\MyFolder
If F: is assigned to another location on C:, you’ll see the ERROR_SAME_DRIVE message.

Pro Tip: Consider using a drive letter that is clearly available to avoid confusion.

Step 2: Move the Directory to Another Drive

If you run into the ERROR_SAME_DRIVE message, try moving the folder to a different drive.

Open the Windows key, type cmd, and launch “Run as administrator.”
Attempt to map a new virtual drive (like Z: ) with the command: subst Z: C:\MyFolder and hit Enter.
To rectify, transfer C:\MyFolder to a different drive using: move C:\MyFolder F:\ and press Enter.
Now that C:\MyFolder is in F:\, map it using: subst Z: F:\MyFolder .

Step 3: Verify Spelling and Avoid Circular References

Double-check the command for typos to prevent further issues. Also, steer clear of circular references that can create confusion in your mappings.

Pro Tip: Ensure that the folder you are mapping does not have any references back to the drive letter.

Step 4: Use an Available Drive Letter

If you need to reclaim a drive letter already in use, delete the existing mapping first.

For example, to free up F:, use the command: subst F: /D , allowing you to assign it again.

Additional Tips

Regularly verify drive mappings and ensure clarity to prevent confusion.
Familiarize yourself with Windows command prompts for easier troubleshooting.
Consult Microsoft’s documentation for in-depth command usages.

Summary

The ERROR_SAME_DRIVE 143 (0x8F) can be effectively resolved by selecting a different drive letter, relocating directories, checking for errors, and utilizing available drive mappings. Awareness of these steps is crucial for seamless navigation in your Windows environment.
