Somebody Help! My 1TB is showing 126mb as storage capacity!

Hi I Just bought a 1TB hard drive, initially it wasn’t recognised by my laptop but after Initializing on Disk Management it’s now showing 126mb. Does anyone know why and what to do thanks

Have never ever had this happen to me … so i googled it

found this:

If none of those suggestions work … i would suggest if you’ve “just bought it” to Return It to where you bought it for refund or exchange.
