Missing cables - Where and what to buy

I found a WD harddrive and do not have the cables, power or USB. Where can I buy these and what size do I need. The SN I believe is WCASU3655138 - 4508A R/N: AOC

S/N and R/N numbers are of no help …

you need to provide the P/N or Model Number of the drive … and a Full Description of what it is

The My Cloud Home does not USB to connect to a computer … so i suspect you’ve posted in the Wrong Forum.
