I want to set a password for my WD Password external Harddisk

I want to set a password for my WD Password external Harddisk.

Hi DigitalGoutam,

WD Security tool provided by Western Digital, is used to password protect supported WD external hard drives. You may refer below link to check the compatibility of drive with WD Security:

I just bought a WD Easystore Drive. I installed the security software, but when I open it it says I need to “Attach a supported WD Drive” My computer is recognizing my drive, but the security software is not showing it.
Can anyone say how I “attach” the drive?

Thanks
