Do not initialize, format, or write to the external drive to fix FreeImage.dll; that DLL belongs to a third-party image-processing library rather than Windows, so protect the important data and diagnose the drive separately.
1. Protect and test the drive
- Disconnect the drive until ready to test it.
- Connect it directly to another USB port—do not use a hub or dock.
- If possible, test it on another computer.
- If it opens anywhere, immediately copy the important files to a different physical drive.
If it repeatedly disconnects, makes unusual mechanical noises, or is not detected consistently on another computer, stop testing it. Do not run CHKDSK against an unstable drive; professional data recovery may be the safest option. A drive that continually disconnects should not be initialized or formatted while data is needed.^1^
2. Check its status without changing anything
Right-click Start → Disk Management, or press Windows+R, enter diskmgmt.msc, and select OK.^2^
Find the external drive by matching its capacity, then note what it shows:
- Healthy with a drive letter: Try opening that letter in File Explorer.
- Healthy without a drive letter: A missing letter may explain why it is absent from File Explorer.
- RAW: Windows cannot currently recognize the file system. Do not format it while the files matter.
- Unallocated or Not initialized: Do not initialize it; that writes disk metadata and can complicate recovery.
- Not displayed or repeatedly disappearing: Check Device Manager → Disk drives and Universal Serial Bus controllers for the device and its status/error code.
Formatting destroys data on the selected volume, so it is not an appropriate recovery step here.^2^
3. Recover the files before attempting repairs
If the drive remains connected, has a drive letter, and Windows can read it sufficiently to scan, use Windows File Recovery with a second physical drive as the destination. Source and destination cannot be the same partition; Microsoft recommends Extensive mode for corrupted disks and non-NTFS file systems.^3^
For example, if the damaged external drive is E: and a separate healthy destination is D::
winfr E: D: /extensive
To target common documents and photos:
winfr E: D: /extensive /n *.docx /n *.pdf /n *.jpg /n *.png
Run Windows File Recovery as administrator and enter Y when prompted. Recovered files are written to a new recovery folder on the destination drive.^3^
If the drive has no usable drive letter, cannot remain connected, or cannot be scanned, software recovery may not be suitable. Avoid repeated repair attempts and consider a professional recovery service, especially if the only copy of the data is on this drive.
4. Repair the separate FreeImage.dll error
FreeImage.dll is supplied by applications that use the FreeImage graphics library; it is not normally a Windows 10 system component.^4^
- Record the complete error and the program named in its title bar.
- Uninstall that program from Settings → Apps → Apps & features.
- Restart Windows.
- Reinstall the program from its original publisher, selecting its 64-bit edition if the program itself is 64-bit.
- Do not download an isolated DLL from an unofficial “DLL download” site. If manual files are genuinely required, obtain the matching build from the application vendor or official FreeImage download page.^5^
An x64 Windows installation can run both 64-bit and 32-bit applications, so the DLL must match the application architecture—not merely Windows architecture.
Only if other Windows components are also failing should Windows system repair be attempted. In an administrator Command Prompt, run DISM first and then SFC; these repair protected Windows components, not a third-party FreeImage.dll installation.^6^
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
