Cannot format 4 TB drive into two equal partitions

[dg27]

I have an HGST 4 TB drive that I use for storage. Right now it's in an external case. I use a WD TV Live, which only recognizes drives up to 2 TB. Since I'd like that device to see this drive, I've been trying to reformat it (I have the data elsewhere) into two ~1863 GB partitions (Windows sees this as 3725.9 GB.)

I use Acronis WD Edition, which I've used to repartition drives many times. Usually there's no problem splitting the drive into two partitions that are the same size. For some reason this is only letting me do one partition as 1.639 TB and the other as 2 TB.

Wondering if anyone else has ever run into this sort of thing.

When I go to Device Manager and check the driver properties for the Samsung 840 Pro it is showing a Microsoft driver dated 6/21/2006. This seems really weird (way before SSDs, right?) Should I replace with a Dell driver?

Yes, you should definitely try with the original hardware manufacturer's drivers, @dg27. As I mentioned Windows tend to install more generic drivers. There is an article about whether or not you should use the hardware drivers from Windows or download the manufacturer's ones. Hopefully, it will shed some light on the reasons why and help with your system's performance in the future.

Good luck!

So for this issue, should I replace all the SATA drivers? It's really hard to pinpoint.

Thanks again.

Hello... Just try and use Windows OS drive tools... any Install disk has Partition/drive tools on it too, if you wanna do it outside Windows OS.
are you starting by Deleting all partitions first?
what format do you need?
1) Try changing the Block size and see if that get you closer.
2) Do this in DOS mode bootable OS.
