Raid, how to on HP DC7900 Convertable Minitower

pitterpat · Apr 7, 2014

Here's the story:
I got this CPU from a friend; it was Raid1 with Vista as the OS. I did a half assed job of researching b/4 I upgraded to Win7 - 32 bit. the HD's are Segate ST3250820A , I don't have any files or programs installed on it yet. I also have a Segate ST330 that I would like to use in this system if possible, all drives are 7200 Barracuda's. As I was reading on this forum I have to Raid it b/4 installing win7. Not sure what steps to take first.

Right now in Bios only one ST325 drive shows that it is mirrored as RAID1, with the RAID ID as 0. It shows I have 2 physical disks in my cpu on Port 0 and Port 2

If I am reading correct I would need to reformat both drives (ST3250820A) first; then raid each drive then install win7.

I would like to use the ST330 from my old system to hold my program files only and put the data files on the 2 Raid drives. Can I do that?

Thanks

yes you can do what you want.
Go into the raid bios, look for the key-combo to press during the boot up sequence and deleted the raid 1 and create a raid 0. Instructions are in the users manual for your motherbd.
make sure you have the raid drivers on a usb stick, you will need them to install windows to the raid.

Why would I create a raid 0 when I want raid 1 (I have 2 drives that are the same) I want to mirrow thme for my data.

Ok I'm confused. You said it was raid 1 and you want to leave it that way? Thats fine. No need to raid drives that are already in the raid you want.
Install your drive, install windows & install the raid driver when asked if you need to. If windows doesnt see your drive you will need to exit and go into the raid bios and configure your drive as raid ready, single, or sometimes even a single drive raid1 array. (All depends on the raid bios). And then go back and install windows again using the raid drivers naturally.

It only shows one of the 2 twin drives as raid; is that the way it's supposed to be?

So what you are saying is to install the 3rd drive and install Win 7on it. Noob question here but should I uninstall Win 7 from the one twin drive that I have....something like this:
1. Format the twin drives
2. Install the 3rd drive and install Win 7 on it.
3. Raid the twin drives or will they already be raid?
Confused/
Thanks!

The twin drives are in raid already and will remain in raid so long as they are connected to the computers raid controller.

What you can do to avoid problems is disconnect the data cables but make sure you mark them so you know which one goes where.

install the 3rd drive to a different sata cable and port and try installing windows. If the win install doesnt see the drive then you will need to reboot into the raid bios and set the drive up as raid ready, single, passthru, or maybe even a single drive raid1 (depends on your raid controller) and this time you will install windows but use the option to install additional drivers (your raid drivers)

Ok, have to get cage for the other HD, then I can mount it up top.

Ok, now that I have Win7 on the new larger drive should I delete win7 from the Raid1 drives? The Raid1 drives will be my data drives.

popatim :

I didn't unplug the Raid1 HD's while doing the install of Win7 so now I have Win7 on both drives, Raid1 and the HD that I want to use for OS and prog files. When I reboot it comes up with that black screen and asks me which Windows 7 I want to boot to. How do I get Win7 off of the Raid1 drives?
