Nope it's NTFS. "Bypass file system filters" is enabled. I'll try to reproduce the problem after disabling it. That aside, i'm just curious - what does the large memory cost in DrivePool come from in these pathological cases with AV scanners?

DrivePool's footprint ranged from 2-5GB before I added all of the pool's drives to NOD32 anti virus's exclude list. At least I'm pretty sure that's what fixed it. Attached is a poolmon screenshot showing a few pools owned by covefs.sys (I think...please correct me if I'm wrong) at or near the top of the list, totaling over 4GB. I wish I didn't have to disable antivirus for those drives, so would love any information from the developers about the cause of this problem or any other way I can mitigate it. Thanks, James

FWIW, the two WD Blue disks in the pool are both "Healthy" in Scanner, as well as my SSD boot drive. I had wondered if it could have been a false error from (in my case) not having many non-duplicated folders, or having too many empty folders, etc... Some corner case you can hit before the pool gets populated.

I copied some more data to the pool, ran "re-measure", and now Pool Organization is green. ¯\_(ツ)_/¯

Okay, I just ran it. Thanks for the help.

I purchased all three tools yesterday and set up a pool with two new WD blue 4TB HDDs. I've copied around 140GB to the pool so far, a subset of which is configured as "x2", but mostly non-duplicated. I have v2.2.0.762 BETA installed (the latest as of today) as well as the latest beta of Scanner. Scanner reports no issues at all. I've run "Re-measure...", "Re-balance", "Re-check duplication" multiple times, and rebooted a few times as well, but Pool Organization is still yellow and the tooltip says "Duplication inconsistent"
