I've submitted dump for service. Checked all disks with chkdsk - no problems found.
There are one disk in pool without disk letter, others - with letters.
Installed CovecubeInc.OrderedFilePlacementPlugin.dll v1.0.2.3 (31.07.2013).
I try to clear all settings tomorrow
Just installed software yesterday and receive this cpu usage on morning. At 04:00 started acronis backup service. Nothing new was installed after DrivePool.
Reboot doesn't helped.
P.S.: OS Windows 8, all latest fixes applied today - not helped.
