Hello
I bought this new Western Digital Green 5TB drive as a storage but somehow Windows 7 Professional 64 bit on both my Dell Optiplex 990 (with A19 Bios) and Dell Studio XPS 8100 (with A05 Bios) cannot see the capacity beyond 561GB (instead of 5TB). I have tried just putting it in the USB docking station and connecting internally via ATA cable but there is no change.
On my Dell Optiplex 990 I even tried to change the primary 1G drive (it is an lab machine so I can wipe and reinstall OS) to using AHCI in the SATA drive options in Bios as I read it may be able to see the full capacity. Yet the problems I am running into now seem to be
1. BIOS don't even see the 5TB drive in the Dell Optiplex 990.
2. Windows cannot even install in the 1GB primary drive once I switch from default rapid storage to using AHCI.
Please kindly advise on how I can use this 5TB drive either as internal SATA or external USB drive in Windows 7. Thanks.
