Yes we know, you told us that in your previous post here.
i cant believe that rapid test takes more that 4 days
Of course it doesn't. It should finish in a few minutes.
could it be that some software prevents test to finish?
I repeat, the test is run on the disk by the disk. The NAS only reports the result.
The first important information to know is if multiple disks are affected or only a few...
If you suspect a NAS bug it would probably be a good idea to reveal what NAS model and exactly what firmware and build date is used so that others could check and see if they can reproduce your issue.
I did also in my previous post explain how you could test the disk in an alternative way that totally exclude the Qnap:

Then ask them how they resolved the issue.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!
