I’m using a Macbook Air running Windows 7 SP1 via BootCamp.
I bought a WD Green 4TB desktop drive and placed in an external WD MyBook enclosure that I’d been previously using with a 500gb drive.
I formatted the new 4TB drive using WD’s windows drive formatting tool.
And the drive only shows as 1.63TB total. No other space or partitions or anything.
I have tried converting the disk to GPT but that is not an option in any disk management system I have tried. That option is always greyed out.
There is no other partion to delete or remove or reduce in size.
I googled this for hours last night and found no solutions.
I’d appreciate any help.
