Apologies if this has already been answered, I searched and couldn't find anything. I'm trying to remove a drive from my pool and I get the message above. The is what the log says My first thought is that the NTFS permission are somehow messed up but looking at the file they seem fine? (Screenshot attached). I found this link about resetting the owner but this doesn't seem to be the issue. (StableBit DrivePool Q5510455 - Covecube - Wiki) Any thoughts on how to resolve this? I'm runniing DrivePool 22.214.171.1247 on Windows 10 64. The drive I'm trying to remove is part of an unduplicated pool which is itself part of a duplicated pool. I know that's a little hard to read but to explain imagine Pool A is a duplicated pool made up of Pool B and Pool C. Pool B is an unduplicated pool made up of Drive A and B. I'm trying to remove Drive A.
