How can I copy data from Disk 1 if it’s an emulation and it’s not mounted? Sorry, have just discovered the copy function.

A question: does a basic array consist of a data disk plus a parity disk? I think I have become confused about the difference between an array and parity.

I am sorry, I’m used to dealing with disks on a Linux system, but I feel somewhat out of my depth dealing with Parity disks, arrays and the like. To try to answer your questions, one of the parity disks is SSD and the other is a regular disk. The failed disk was originally ntfs, but I thought it had been reformatted. Maybe when I first set it up, this disk was just a data disk and the SSD was the parity disk. I can connect another drive and copy the data from Disk1to it. I’m not sure exactly how to do this, but I can figure it out. Then I can rebuild the array, as you suggest. Maybe I should use the hard disk for the array and use the SSD as a data disk? Your help is very much appreciated.

I am puzzled by the 'ntfs' as I said in my post. I thought the parity drives had their own formatting standard? Anyway, here is the diagnostics file. thinkcentre-diagnostics-20260824-1436.zip

My setup has two 2Tb parity drives. One of them failed, and I was left with a single parity drive and an emulated drive, 'Disk 1'. I installed a new replacement drive, following the advice in https://docs.unraid.net/unraid-os/using-unraid-to/manage-storage/array/replacing-disks-in-array/. However, I encountered a problem where in the advice it says "If you started in Maintenance Mode, go to the Main tab and manually click Sync to start the data rebuild." I couldn't find anything at all that said 'Sync' in the Main tab under Maintenance Mode. I clicked on something which seemed similar and the parity process started. It took about 24 hours to complete. Then I rebooted, everything came up correctly, but Disk 1 is still there with its little X next to it. According to the Shares tab my data is still there (and it also shows up with the little blue box icon before Disk 1). It is listed as being held in 'Array'. Has it transferred to the two Parity disks or is it still being held in the 'emulation' in Disk 1? I also can't understand why Disk 1 shows the FS as being ntfs. I have a suspicion that all is not well and that my data is at risk. How do I make sure the data is being held properly on the two Parity disks and how do I then get rid of 'Disk 1'? There is probably an answer to this, but I have done a lot of searching and nothing promising has shown up. I may be using the wrong terminology. Anyway, any help is much appreciated.
