New Hard drive - isn't recognised

Hi
I am running the New Windows 10 and all updates have been completed.
I have a Foxconn G31mx series mother board, which is SataII.
Normally I use 3 hard drives with it, for backups mainly but recently had a seagate 1tb crash and have tried to replace it with a WDC WD10EZEX 1tb SataIII hard drive. I was under the impression that it would be backwards compatible. ie would run but at SataII speeds.

Although device manager and Speccy all see the new drive ( reporting its working correctly ) it isn't recognised in windows. I have even downloaded the wd data lifeguard tools software which also says its working.

When I look at its properties via device manager it says in the events tab

"Device IDE\DiskWDC_WD10EZEX-00BN5A0____________________01.01A01\5&23228290&0&1 .1.0 could not be migrated.

Last Device Instance Id: IDE\DISK_____________________ ___\5&2023E8FD&0&0.0.0
Class Guid: {4D36E967-E325-11CE-BFC1-08002BE10318}
Location Path:
Migration Rank: 0xF000F8000000F120
Present: false
Status: 0xC0000719"

Any thoughts?
