How to Stop OneDrive Scanning an External SSD After Reconnection
Question details
The user wants to stop or minimize OneDrive's automatic and lengthy file scanning process when an external SSD is reconnected to the computer.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Reconnecting an external SSD that contains folders actively synchronized with OneDrive.
- Observed behavior
- OneDrive automatically scans the entire external drive upon reconnection to verify synchronization, causing delays and keeping the drive constantly active.
Ensure your external SSD is securely connected to a stable USB port and check that your computer has an active internet connection to communicate with the OneDrive servers.
Manage Sync Habits and Reduce Selected Folders
Since it is impossible to completely disable the scan without turning off synchronization, the best approach is to minimize the amount of data OneDrive needs to check and to pause syncing before unplugging the drive.
OneDrive is designed to verify all files upon reconnection to ensure data integrity and track any offline changes. While you cannot bypass this necessary change check entirely, you can significantly reduce the scan duration by limiting the number of synced folders and adopting better disconnection habits.
Click the OneDrive cloud icon in your system tray, select the Help & Settings gear icon, and click 'Pause syncing'. Choose a duration (e.g., 2 hours). Safely eject your external SSD only after the sync is paused.
When your SSD is reconnected and OneDrive is running, right-click the OneDrive icon in the system tray again and select 'Settings' from the menu.
In the Settings window, click on the 'Account' tab to view your connected services and local storage usage.
Click the 'Choose folders' button. Uncheck any large or unnecessary folders that do not require continuous synchronization on this specific external SSD. Click 'OK' to save. This limits the total number of files OneDrive must process during its next reconnection scan.
Experience Seamless File Management with WPS Office
If background syncs and heavy drive scans are slowing down your workflow, having a lightweight, efficient office suite is crucial. WPS Office is a highly compatible, free alternative to Microsoft Office that lets you smoothly manage and edit documents directly from your external SSD without heavy background scanning delays.
- 1. Download and Install: Visit the official WPS Office website to download the free installer and follow the on-screen setup instructions.
- 2. Open Local Documents: Plug in your external SSD, launch WPS Office, and open your documents instantly without waiting for cloud verifications.
- 3. Save with Ease: Edit your files and save them securely back to your local SSD in standard Microsoft Office formats.
Frequently Asked Questions
Can I completely disable OneDrive's scanning when reconnecting a drive?
No, there is no supported setting to completely disable the change checks while continuing to synchronize the drive. OneDrive must perform this scan to ensure files match exactly with the cloud and prevent data loss.
Why does OneDrive need to scan my external SSD every time?
When a drive disconnects, OneDrive loses track of the file system's live activity. It must scan the entire drive upon reconnection to detect any modifications, additions, or deletions that might have occurred offline.
Will unchecking folders in the 'Choose folders' menu delete them from my cloud storage?
No. Unchecking folders simply removes them from your local external SSD, stopping them from syncing to that specific device. The files will remain safely stored and accessible in your online OneDrive cloud account.
How can I prevent accidental disconnects that trigger a rescan?
Ensure your external SSD is connected to a high-quality, stable USB port (preferably directly to the motherboard on a desktop PC). Avoid moving the cable or drive while in use, and make sure your computer is not set to turn off USB power to save energy.
