RAID 0 is very risky if used with old HDDÂ´s.
Event log usually shows entries when a disk becomes faulty.
We had that in the test lab, the machine threw test errors.
After replacing the Disks it runs smooth again.
To recover data from the old system youÂ´d need to temporarily
add it as secondary disk in a RAID 0 configuration again.
