I need help on how to configure my WD 1TB external HDD. once i plugged in the drive it's not showing in my computer. when i tried going to diskmgmt.msc, changed the volume letter an it works but after deleting/moving some items in my desktop, it froze up and could not recognise the device anymore. also right after unplugging the drive, getting an error 'need to reformat the drive'. thanks in advance.
