Thanks for the information. The HD-QLU3R5 appears to be an older model of the newer HD-QHU3R5. Almost every place that sells the HD-QHU3R5 model also advertises SecureLock as an available tool (likley Copy/Paste from the Buffalo site). So Buffalo Tech made a new model of the drive, removed ability to encrypt and did not update their product literature for the new model?
Any advice on best way to lock the drive down for transporting between sites?
