3TB drive only showing as 746.52 GB

Hi All,
I have got a WD red 3 TB drive in an enclosure. I have initialized (GPT) and formatted the drive however it only shows as 746.52 GB. Using windows 10. Any advice on how to get it to show the correct capacity?

 

Is it partitioned?

r/c on windows start and choose disk management.

 

Is the enclosure old?

 

I initialized the disk and created a single partition

 

Enclosure is about 2 or 3 years old but has been working fine with my 2TB drive

 

Had a quick look, seems there are 3 common reasons for this:

1. Your enclosure may have a 2tb limit

2. You formatted in MBR rather than GPT

3. Intel RST driver 10.0.0.1046 may be causing this and needs updating.

 

Thanks for your reply.

Was formatted to GPT

Over the weekend I'll try connecting it directly to motherboard

 

Let us know how it goes.

I can see how a duff Rapid Storage driver may mess things up but i'd never even heard of the fact that some enclosures can have limits.
