Dead Hitachi drive?

I had two 1Tb Hitachi drives that were in a RAID0 system for a few months. Then I upgraded to an SSD and new CPU and board.
I'm repurposing them in teh new machine but one seems faulty. It shows up in the BIOS but not in Windows.

I've tried to install Win7 to it again but it doesn't show up during the install.

Any ideas?
 
Does it appear in Disk Management?

Right click on 'Computer', select manage and then click on Disk Management.

If it does, but the space is unallocated, then right click on the unallocated space to format the drive and assign a drive letter.
 
hmmm...something really weird is going on. The drives are ok, I've installed Ubuntu on them to test each one and they seem fine.

When I reconnect them and the SSD drive they all show up in the BIOS, but only one of the Hitachi's as a boot disc, I have to force the PC to boot from the SSD.
In Windows Explorer they don't show up.
Using Computer Management they don't show up either except for a 1.8Tb Unallocated Disc0. It's Uninitialised and won't either...

I've tried using EASEUS Partitin Manager and it sees the same thing, Disc 1 is Unallocated 1.8Tb, the SSD is Disc 2.

Is there some data on my SSD that is screwing things up?
 
The 1.8TB space is your two 1TB drives which it would seem are still being seen as RAID 0 unless you have any other drives connected.

You need to break the RAID array.

Before you do that I assume you didn't have the HDD's connected when you installed Windows on the SSD?

Edit:

I assume you have no data you want on the drives?

No, I backed everything up to another drive (and an external drive) which is sitting unconnected for the time being.

The SSD was installed on its own, then I reconnected the two Hitachi's to format them asI wanted to use them separately within the machine.

Try just connecting the HDD's one at a time and see if you can intialise and format them that way.

That's the odd thing, even one at time it shows up as a 1.8Tb Unallocated disc. Which is why I'm wondering whether there is some data written to the SSD that is causing this.
When connected on its own the SSD shows up as a single disc with only one partition. With the Hitachi connected a second 100Mb partition appears.

If the HDD's weren't connected when you installed Windows I don't see how there can be anything on the SSD which relates to them.

If the RAID array was created on an Intel chipset then if you change the SATA mode to RAID you may be able break the array.

Change to RAID mode, access the RAID setup using "Ctrl I" during the boot process and then delete the RAID array.

Change back to AHCI mode afterwards if you're not going to be using RAID again.
