Does the Ultra need scanned?

Do external HD’s like Ultra need to be scanned/defraged regularly like the PC hard drive does?

If you are talking about AV scans it would depend on how you use the drive. I only connect mine when I make system images after scanning. When I sync up data I scan the individual files first. I also don’t have a browser open when unsing the externals. If you are constantly connected and downloading straight to the drive I would scan frequently.
