WD 2 TB HDD not accessible

so i bought this 2 tb external hdd today and first thing i downloaded the wd discovery app, i could see the space and i tried to copy photos and it worked, i tried to set up a password and i successfully did from the app, but once i did, photos stopped transferring, i disconnected the drive and connected back again, but it shows up as a cd rom without space and now i get A:/ is not accessible, the request cannot be perfomed because of an I/O device error, i tried disk management where the drive shows up without any space, disabled the VC but didn’t work, unistalled the drivers didn’t work and i’m lost how to even get this thing to work.

如何“重置BIOS”???我的10T Mybook 也有这样的问题,快疯了!
