I ended up just moving to SnapRAID and this seems to have resolved the issue. The downside is there's no real-time parity, but I do like that I can configure it to scrub files routinely to detect corruption, which FlexRAID did not do.

I've got an SSD and a scratch disk set as SSDs in the SSD optimizer. I don't want certain files to go to the scratch disk, so I set up file placement rules such that those folders are excluded from the scratch disk but included on all other disks. However, now DrivePool is moving files off of my archive disks onto the SSD and back again. Very irritating, particularly as I'm using SnapRAID and this is making parity recalculation very challenging. Not sure why the program is behaving this way - doesn't seem like the correct behavior. Please advise.

Oh thanks - hadn't seen that option. Not sure why I'm running into this with DrivePool and not with FlexRaid pooling. After restarting my computer it largely seems to have stopped creating errors in files copied to my cache drive, but I'm still getting errors once the files are moved off the cache drive onto my array. How does Verify After Copy work? Will it try to copy again if there's an error? Just keep the file on the original drive and notify you that the balancing failed? Or move the file, identify an error, tell you there's an error but delete the original?

@Catch-22 were you able to resolve this issue? I'm running into something similar with MKV files (usually multiple GB).

I have DrivePool installed on two computers - one where I've had it installed for quite a while with no issues, and another where I just finally migrated from FlexRaid pooling. I have the SSD Optimizer plugin installed but am using it to cache files on a regular 3 TB hard disk before moving them to my array (the other drives, but not this disk, are still set up with FlexRaid transparent RAID to provide some protection via parity). Although the speed of this pool is much quicker than with FlexRaid, I'm running into some disturbing file corruption issues. I've compressed a few movies with StaxRip and the resulting file, when placed on the pool, will have corrupt sections (note this is on the 3TB cache drive that is not set up with FlexRaid). Some of the movies worked fine when muxed to the cache drive, but then when file balancing runs they'll get corrupted when they get moved to a different drive in the array. This makes the product unusable. Any help would be appreciated.
