Solution

1. Make sure the drive has complete permissions to create the Deduplication storage on the selected volume.

2. If it is Windows server 2008, make sure User Access Control (UAC) is disabled.

3. Try to create the Deduplication Storage folder on a different drive. If it is successful, it could be a problem with the drive.

4. Format the drive which has issues and try to recreate the deduplication folder again.
