Cannot install Snow Leopard on a certain HD

Hello,
I really hope you can help a newbie!
I have two internal hard drives on my ancient Mac pro 2008.
One I want to keep with Yosemite, but the other I want to reinstall Snow Leopard on, so i can run FCP 7 without the problems I have running it with Yosemite.

I have erased the drive, so there is nothing on it at all and it is formatted to Mac OS Extended (Journaled), but when I run the install disc for Snow Leopard, I cannot see the drive to install it onto.

When I boot up with the alt key and got to recovery-I can see the drive in Disk Utility, but it is greyed out when I try to partition it. Please see photo.
I can erase it again, but that is all I can do to it.
I think I need to add a partition for the computer to see it when I try and install the Snow Leopard install disc?

Can anyone suggest how I can install the Snow Leopard OS onto this drive as I am stumped! Many thanks

Is that the start up drive?
[doublepost=1476462610][/doublepost]Sorry=being really thick-the drive I want to install Snow Leopard onto is Highflyer A
thanks!
 
Maybe since the recovery partition resides on the Startup drive maybe you could use the CD or put it on a USB2 drive and boot from that to repartition the startup drive and then reinstall OS X after the partition!

Thanks.
I have tried that- booting from the start up disc and an external drive- disk utility always sees Highflyer A but won't let me partition it.
Any ideas?thanks so much
 
OP -

My suggestions:

First, shut down, power EVERYTHING off.

Next, DISCONNECT all those non-essential drives that I see in your pic of Disk Utility.

The ONLY DRIVES you want connected are the target drive and the DVD from which you'll be installing.

I see you're on a Mac Pro.
You MAY have to open it up and pull some cables.
Once all the non-essential drives are disconnected, close up.

Now, boot from the install DVD.
a. press power on button
b. hold down option key until startup manager appears
c. select install DVD, hit return.

When you get to the installer....

FIRST, you want to re-initialize the target drive using the copy of Disk Utility that comes on the DVD (with the installer).

NOW try doing the OS install.

Try exactly what I've proposed, and get back to us.
Any better?

Thank you
ok-I have turned everything off, disconnected all the external drives-I tool the side off-

I cannot see anything else to disconnect.
I booted up off the install disc-went to disk utility, but I still cannot do anything to the other drive-now it is 4.5TB Untitled-I can see the raids, but not sure if that makes any difference?

I also went to Startup Disk on Utilities and it doesn't see the drive there either.

Sorry to seems thick-am I missing something? thanks so much

Where did high flyer go? I think it's because the 4.5 is a RAID array - so you may have to install on a RAID slice depending on the setting?

That's what I see when I boot from the Snow Leopard disk. When I boot up
From the recovery drive- as it calls itself- I can see it called Highflyer A?!?!?
 
When I boot up holding down alt, this is what I get

Then if I go to Recovery 10.10.5 and then disk utility, I can see this

So here I can still see Highflyer A, but cannot do anything to it-partition is greyed out still.

Any suggestions would be so welcome.
Thanks so much
 
Hi,

You have a Core Storage on HighFlyer A disk.

You won't be able to install Snow Leopard on it because SL can't "see" a Core Storage volume.

To install SL on it you'll need to get rid of the Core Storage first.

Please launch the Terminal and post the output of :

diskutil list

Then :

diskutil cs list

You can copy and paste the results from the Terminal window.

OP:

If you have ANOTHER Mac available to you, you might consider taking the drive OUT OF the Mac Pro, putting it into an external enclosure (for the time being), taking it to the other Mac, and try to install the OS that way...
 
I don't have another mac....
is there any other way I can do it?
Thanks so much
