Windows 7: Gaining access to old Operating Sytem drive.

Gaining access to old Operating Sytem drive.

Hi Everyone

Apologies in advance if this has been posted in the wrong place, but having a look around it would appear to fit with what my problem is.

My problem is simple. I had 4 HD's in my Computer 2* 500G in Raid as an operating system and 2*1tb drives for storage. Everything was working fine but the OS needed a formatt and refresh basicaally.

So to take advantage of this and free up 1TB of space I bought a 64G SSD, physically installed it and went about setting up this as my OS from scratch. However, in my haste I forgot to remove a couple fo folders of important documents from the old OS drives.

The SSD is the Boot drive now and I can see all other HD's in my computer, but the problem is I can not gain access to, lets call it H:, which was the old OS drive. I have been able to initiallise one of the old OS raid drives through disk management, but am unable to gain access to H.

It tells me I need to Formatt the drive first, and then comes up with a speil about access being denied. I gather this has to do with the old OS being installed on it, I am happy to formatt the drive enventually. But I really need to get some docs off it first.

Is there anyway to do this, I have been searching for an answer but not getting anywhere?

I tried to change the boot order also, as all other system specs remain the same. But I think because I have removed the Raid set up of the drives I am unable t load the old OS.

Thank you for your help.

Try putting things back the way they were. You might have to do a startup repair.

The only change is the install of the SSD as the operating systems and the removal of the Raid of the two drives.

I will mess around again tomorrow but I was hoping I could aviod, disconnecting the SSD to get into the old OS Drive. I would imagine it has to be something that can be done from the new OS. The old drive is there with all the files on it, I know it works as it was wokring this morning before I put the new drive it.

Obviously you have to rebuild the RAID to have any chance to regain access to the data, and even that is not certain since you've unRAIDed.
