Welcome Antonio Mota,
Thank you for reaching out to Microsoft Q&A. I understand that Windows 11 is showing duplicated disk drives.
To help narrow this down, could you please confirm:
- Do you see the duplicate drives under File Explorer > This PC, in the left navigation pane, or both?
- Do both drives have the same drive letter, such as D:, or different letters?
- Is the affected drive an internal drive, USB/external drive, or network drive?
While checking, please try this quick test:
- Press Windows+R, type
diskmgmt.msc, and press Enter. - Check whether the duplicated drive appears as one volume or two separate volumes there.
- If it appears only once in Disk Management but twice in File Explorer, please let us know the drive letter and name shown for both entries.
- If it appears twice in Disk Management, please do not delete, format, or change either volume yet, particularly if it contains important data.
Looking forward to your update.
