See parity swap.

it wont let me keeps saying to many drives missing

 

I missed that in your screenshot disk2 is showing as new, you cannot add a new disk at the same time you are trying to rebuild another.

I have tryed this it just says it missing a drive the disk 2 when there was a disk in there it never formatted it just failed and I removed it

this is when looking at the super.dat if you look at the first screen shot that's the drive that never worked and yes I know its a SSD I have a rma for it but have not mailed it yet

If there was a disk there and you let it remain disabled, now you will be stuck, since you have two invalid disks with single parity.

is there a way to remove that disk from the config as it had no data?

you are right I am stuck lol its why I have asked to help

Unfortunately not as the system would have been assuming its presence in all parity calculations.

 

Are you actually sure that you had a disk failure or did you just assume it had failed because it was marked with a red 'x' to indicate it has been disabled?   The red 'x' means that a write to the drive failed so it is no longer synced with parity, but often the write failure is caused by an external factor and the drive is actually OK and most of the data on it can still be intact and recoverable.

It won't attach the drive and it makeing a funny nose click clonk click

Can I get the data if I send it away will providers work with xfs ?

is it possible to read the data on the parity without unraid using a tool there is like a hand full of files I need and it was almost used like mirror as the other drive did not have files on it

Having no data doesn't really matter, do you know if that a new never used before disk, or a disk that was precleared or cleared before adding to the array?

so it tried to pre-clear on the 500gb but the drive never cleared and the drive still had windows on it, unraid never got the drive to clear but when switched to unattended it never got removed either unraid would attach the drive (500gb) and keep requesting to format it and could never format it and that's why I need to remove it from the super.dat or replace it with another 500gb I have it doesn't matter as long as I can get a few documents I need off the drive so I can recover the drive that has died I hope this makes sense

 

another question can I put 2 8tb drive in place of the 14tb that died is that a option there was 12tb used on it

That won't help if the drive wasn't clear, but if you want to try, since at this point there's nothing to lose:

 

-Tools -> New Config -> Retain current configuration: All -> Apply
-Check all assignments and assign any missing disk(s) if needed, including the new disk1, replacement disk should be same size or larger than the old one, don't assign a disk2
-IMPORTANT - Check both "parity is already valid" and "maintenance mode" and start the array (note that the GUI will still show that data on parity disk(s) will be overwritten, this is normal as it doesn't account for the checkbox, but it won't be as long as it's checked)
-Stop array
-Unassign disk1
-Start array (in normal mode now) and post new diags
