I installed DrivePool 64bit on 4/4/2015, since then my application log is just filled with 'Volume Shadow Copy Service error: Unexpected error DeviceIoControl'. Today alone there are easily more than 100 log entries for this. Why am I getting so many Volume Shadow Copy Service errors? This is the last one I received:
