Got a 3TB Seagate...want to set it up as an external USB3 backup HD...I also purchased a USB3 HD enclosure...

Went to Disk Management, HD shows up with 2 unallocated partitions...2gb and about 750 gb...
I Convert To GPT disk and it creates one unallocated partition about 2.8 Gb in size...
I go to New Simple Volume...I take the defaults...perform quick format...
Disk Management assigns a drive letter...then I get
error message...."The format did not complete successfully"......

So I delete the volume and I get one 2.8 Tb unallocated partition...

I convert to MBR disk...I get 2 unallocated partitions, 2 Tb and about 750 Gb...same as when I started...
I can create a New Simple Volume on the 2Tb partition...but I cannot on the 750 Gb partition...
And when I try to format the 2 Tb partition...the format fails...

So...what am I doing wrong...is there a way to correct this...

PC does NOT have UEFI...just std BIOS...but if nothing else I should still be able to format the 2Tb parition...shouldn't I...????
