Hard disk input output error

Hello everybody, I switched from OMV 2 to OMV 3 a few month ago.
In happened me more than one time that suddenly hard disk data began to give input output error : don't know the reason because ale ALL NEW: 1 SEAGATE BARRACUDA 1TB and 1 WDRED 3TB.
Once unmouted the disk PASS the Wd Lifeguard test adn the Seatool test with no problem . As well, 100% functionality is reported in Hard Disk Sentinel and 100% health in HDTune pro .
In other worlds, the disks seem to be ALL RIGHT .
Never had problems in OMV 2.
Did someone else experimented such a situation?
Thanks in advice
