Windows 7: 3rd SATA hard drive won't format correctly

3rd SATA hard drive won't format correctly

m/b: ASUS P5Q-EM CPU: Intel Core 2 Duo E8400, 3000 MHz (9 x 333) O/S: Microsoft Windows 7 Ultimate RAM: 8GB Hard Drive: 2 x SATA 250GB - Hitachi Deskstar T7K250; Seagate Barracuda 7200.10 250310 DVDROM: ASUS DRW-2014S1 ATA Device x 1; ASUS DRW-24B1LT ATA Device x 1 I have two SATA hard drives as can be seen above, and today bought a third drive - a Samsung 1TB SATA drive. I attached the drive and booted the machine. BIOS can see the drive. Windows Disk Management can see the drive. But... When I format the drive, it always comes up as a RAW partition and Windows cannot see it. Can someone help me to solve this problem? How can I successfully format this drive with, say, 4 partitions that are NTFS, not RAW?

Tell us the exact steps you are using to format the new HDD.

Or, you can follow this guide,

Create and format a hard disk partition

When formatting use NTFS and 'Quick Format'.

Or this Win7 tutorial How to Create a New Partition or Volume in Windows 7.

Try a full clean & full format in command prompt.

Disk - Clean and Clean All with Diskpart Command
Partition or Volume - Delete
Partition or Volume - Create New

1) Elevated Command Prompt (for command prompt)
2) Boot DVD, & Press Shift+F10 (for command prompt)
3) Command Prompt at Startup (for command prompt)

Type in command line
LIST DISK OR List Volume (If you have partitions)
