USB drive says access denied when you try to open it
Access denied is always a Windows permissions issue, not a broken drive. Taking ownership of the drive in Properties fixes it in about 5 minutes.
Windows uses permissions to control who can access drives. If a USB drive was formatted or last used on a different Windows account or computer, this computer's account doesn't have permission to use it. Taking ownership fixes the permissions and opens the drive.

- ✓Try opening the drive by right-clicking in File Explorer and selecting Run as administrator — sometimes that's all you need

Skip, I just want a technicianCommon mistakes to avoid
- Formatting the drive to fix access denied — this erases all your files forever
- Plugging and unplugging the drive repeatedly thinking it's a hardware problem — it's a permissions issue, not hardware
Signs you need professional help
- If the drive is encrypted with BitLocker and you don't have the recovery key, or if taking ownership doesn't work and the Security tab is missing, book a CommandIT session to recover access.
