Neither do I, and yet here we are

And yet that's exactly what happened. Yesterday I was trying to get the cache drive working and for that I connected my NVMe-2-usb reader, however Unraid was unable to detect it which is why I ran commands like `dmesg`, `lsusb -t` etc. in the console but nothing destructive (I'm am advanced GNU/Linux user), the only command I wasn't sure of which may have caused something, was from this thread: https://github.com/raspberrypi/linux/issues/4130 echo "0bda:9210:" | sudo tee /sys/module/usb_storage/parameters/quirks Later I switched the internal drive in the reader and then Unraid was able to detect it, so the other drive was not properly plugged. However, none of this explains why my internal drive which I had never touched, was formatted... Happy to provide more info (tried `journalctl` which doesn't seem to exist)

I 100% did NOT tell Unraid to format it. I once accidentally selected it in a Dropdown but *quickly* deselected it (as I was plugging an external disk). I selected the external disk, and I formatted *that*. I didn't check the primary Windows disk at all so I have no idea if it happened sometime during these operations or if it is completely unrelated. Either way, I was able to recover the partitions using TestDisk (first answer in https://superuser.com/questions/133799/how-do-i-restore-a-partition-without-losing-the-data), it was able to find my partitions and write the partition table and thankfully my data is back however I'm not struggling to get the disk bootable again... But this should not have happened in the first place, that is definitely a bug.

Hello I have the same problem. I tried Unraid on my Windows desktop and used my (secondary) 500GB SATA SSD as the primary array disk. After connecting an external disk and using it as the cache, my primary 2TB internal NVMe SSD which had Windows 11 / NTFS got formatted apparently. I made sure to not assign that to any disks. Is there any way to undo that? Specifically what sectors would I need to provide? There were crucial files on that disk, please help
