WD Pasport 500GB

Hi for the past few hours I have been trying to figure out why my Passport WDBBEP0010BBK-01 KEEPS TELLING ME MY TOTAL gb are 31.9 total and 31.9 free space, I have formatted in NFTS and restored defaults and yet it still gives me 31.9 of free space, is this unit now junk
Regards,

What does the partition manager / disk manager of your OS say?

I am sorry but what is that disk manager of my operating system, how do I find that out.
Mike

Ok I am looking at MY Passport allocation size and it says primary partition 31 Gb and 891 GB unallocated so how do I cange that so I have all 1 Gb of storage.
Mike

Delete the 31 Gb partition.
Create a new partition using all available space.
Reformat that new partition.

Ok Tony I will do that and if you do not hear from me again I thank you very much for your help, sometimes I wish I was much younger than 77 I might have been able to figure it out, Regards,
Mike
