Storage Capacity

I bought a My Passport Ultra a few years ago. How can I tell the size of the storage? Serial # starts with WX6. Thanks.

Serial numbers provide no information on the capacity on the hard drive

Model numbers almost always do

eg.
1 TB

WDBC3C0010BSL-WESN

2 TB

WDBC3C0020BBL-WESN

2 TB

WDBC3C0020BSL-WESN

4 TB

WDBFTM0040BBL-WESN

4 TB

WDBFTM0040BSL-WESN

5 TB

WDBFTM0050BBL-WESN

failing that … plug the drive into your PC and right click on it and select “Properties” which shows the total capacity and the capcity used.
