Problem to work with flexRAID disk pool

Help & Support
1

Hi,
I am using DirectoryOpus 10.5. I am testing a software RAID called flexRAID(Transparent RAID) but when I tried to copy files or folders via DirectoryOPUS to its disk pool. I got error message as attached. it says "The parameter is incorrect. (87)". The same action I did via Windows Explorer had no problem at all.

Is there anyway to resolve this?

That affects TeraCopy as well and looks like a bug in Flexraid:

Setting Prefs / Misc / Advanced / copy_nonbufferio_threshold = 0 should work around the problem, at a cost to cache memory use while copying large amounts of data.
