Hard drive shows in device manager and at at boot

I have two identical Western Digital SATA hard drives both 250GB. The
PC knows both devices are there in the bios and device manager but
when viewed from my computer it only shows a single SATA drive with
250gb storage ??


Vista was installed as a new install not upgrade.

Hello,

could it be that your hard drives are built in a RAID? This would mean that
your data is mirrored onto the second drive for data security and therefore
there are only 250 GB available.

Greetings,

Hello

If it is I didnt tell it to and dont want it !!

How do I tell the PC not to use RAID?

Hello,

if it is being used, you can switch it off in BIOS.

Been messing around with that and cant see where to turn it off

Out with the manual I guess.

Just for info MB is a MSI 975X Platinum power up edition

I know for Intel motherboards, there's a setting in the BIOS that reads
something like: "Show SATA as:" and then the options are IDE or RAID. You
should have it set for IDE if you don't want to use RAID.

Cheers

Is the second drive formatted?
The OS won't display it if it isn't

In computer management/disk management, right click and mark the disk as
"active".
Reboot.

Manual says...

BIOS > Integrated Peripherals > SATA Devices Configuration

Your settings should be something like:

SATA Mode: IDE or AHCI (AHCI should be faster, IDE used to install Windows
that doesn't have SATA controller drivers like XP)

On-Chip Serial ATA: Auto or Enhanced Mode should work.

That should be all ya need. If that fails then could be something wrong with
your second HD or the SATA controller. Try a different SATA port like SATA3
or 4.

Good luck,
A.

Lest this confuse anybody, that is *not* strictly correct. There is
more than one kind of RAID. What you are describing is called RAID1,
or mirroring. RAID0, on the other hand, or striping, is not redundant,
and does not work the way you describe.
