Need User Manual for WD Smartware P/N WDBAAF001

I haven’t used my WD backup (p/n WDBAAF0010HBK) in years. I plugged it up and see it still works. Can’t find User Manual and want latest updates. Can anyone assist how to get these?

You can download WD Universal Firmware Updater to let it check if there is a new firmware for your drive and do the firmware update. About the WD backup software you can download a copy of here https://support.wdc.com/downloads.aspx?lang=en
