February 10, 20251 yr Hello, I am relative new to the UNRAID game and I just setup my server and I ran into an issue I could not find so far in the forumsm - sorry if I missed it. The issue: I added a new SSD, tried to format - failed, so I formated it with Unassigend Devices Plus from vfat to xfs. When I tried to put it back into the array it still showed up as vfat and was still unmountable and was still failing formating. So I thought - just remove it from the array - nope… it won't remove and won't start because too many disks are missing, and there is no checkbox to start it anyway. Maybe relevant info: I did not install a parity drive yet because i had to move my data from my old external drive onto the new one, and the old one should become the parity later. I am getting it, that I can't have a single drive failure like this but the drive I want to remove was never used because it is unmountable, idk why it won't start without a drive what was never able to write to. I also could not figure out how to download a log file, but this could be because my brain is not working very well anymore after hours and hours of troubleshooting... It would be nice if someone could tell me how to solve this issue.

February 10, 20251 yr Author Thank you for that, I saw that but I assumed it will delete all data. Can I be sure, that the data will be preserved, because I already formated the original drive. Edited February 10, 20251 yr by Uddie
February 10, 20251 yr Community Expert All data from any array data drives will be kept, the only danger is if you assign a data drive to a parity slot.

February 11, 20251 yr Author Yes I know that, but it is already better than what I had before, and I will get a Drive for actual backup soon, maybe I just leave that unmountable drive in there until I have that and can make an actual backup before doing that! Thank you for your fast help and tips!! I will let you know if I could have solved the issue as soon I tried it.
