Data needs to be kept confidential, protected and compliant with corporate retention policies. If a drive fails while covered under warranty, Lenovo's Keep Your Drive Service (KYD) allows you to keep your drive, improving data security and potentially alleviating civil liability risks for organizations handling sensitive information. Under the terms of the Lenovo Limited Warranty, when Lenovo replaces a defective part, that part becomes the property of Lenovo. If a customer's drive fails and it is still under warranty, KYD lets them keep their old drive and hold onto their data.
