So recently I had two drives in a three drive array fail. I was wondering if I am able to image the drives, how could I replace them without losing data or corrupting the array? Can I just dd the image to the new drives and throw them in my Unraid box?

Your proposed solution is completely on the wrong track.

 

Do not remove the drives.

 

Before changing anything at all, go to Tools - Diagnostics and post the complete diagnostics zip.

 

My description is very vague, I should clarify. About a week ago I began building a new server to replace my aging server. During the transfer process, my power supply failed and shorted out the motors in two of my three hard drives. As such, I can't restart my Unraid array and I can't replace a drive to have my parity drive recreate it. I was going to have a data recovery service attempt a platter swap into a donor drive but, if they do that the serial numbers won't match. So, with that all being said, is there a way for me to swap in the donor drives after the fact?

 

I appologize for the initial shotty explanation, it's my first time on the forum.

Which is why I thought you might not be familiar with the normal ways of working with disks in unRAID.

 

If you get the platters with their data back but the serial numbers are different, then you will have to set a New Config. Then unRAID will just accept the disks with their contents. It's possible it won't be able to mount one or more disks if there is any corruption. In that case, don't accept the offer to format. Instead, try to repair the filesystems.

I was hoping this would be the case, thank you for the info!
