Is this Raid-5 recovery Possible?

[Seriouz]

I just upgraded a 64gb ssd to a 128gb ssd installed windows and my raid drivers.I have 4x2tb drives in a raid 5 array. Windows asked to initialize the 4 disk and I did, not realizing this would be a bad thing. Amd's raid expert utility shows the R5 array as normal with the volume name unchanged R5Repository, The Bios sees the R5 array normally as well with same naming convention.When I go into disk management it sees the raid disk as a single disk but two volumes one being 2.048GB and one 3.539GB. I can not see me Raid in windows and i am out about 6tb and 10yrs worth of work. How do i get windows to assign this array and access my data once again?

Before you fiddle with it anymore, download r-studio and see what you can piece together (free version will suffice for now). It will probably be a lot less risky to dump the data to another set of disks than trying to modify what you have already (which is a bad idea considering it's presumably your only copy).

Initialize = reformat.

r-studio it is. Ill see what I can find. I do have the ability to dump the data to individual disk if it is still there.

Not true, if you do a quick init it does not reformat. The trick is to initialise the array with the exact same settings as you used before. The stripe size needs to be identical, I have successfully initialised a deleted array in this way. For example, I had an array with 2 failed disks as a result of power failure, the disks themselves and the data contained therein was perfectly fine, so I deleted the entire array then did a quick init with the same settings and the array came back online as healthy, the data was intact and there was no rebuild necessary.

Before you do ANYTHING (If you are unwilling to $$$up and get professional data recovery) you should get 4 new 2TB disks and make a bit-perfect backup of each of your existing 4 2TB disks so whatever you attempt you can always go back to the baseline you are at now prior to recovery attempts.

I highly recommend this.

If you do not switch the disk order or change any of the parameters (like chunk size...) an initialize does not have to overwrite the data on the disk. I have seen this in linux software raid at least.
