I am trying to reduce my number of disks down to 8 in total so I do not need to power up the diskshelf. So the 3 , 4Tb and some of the 8Tb drives will be going. I have a 14Tb and another 18Tb to add.
What sort of corruption on disk24?
I have looked at what is on the other appdata folders on non cache drives and they appear to be (almost) empty, just a folder structure.
The system folder on Disk 2 is a folder called docker with 400Gb docker disk image file in it, the docker folder on the cache drive is empty.
