I have a ssd drive with the OS, and two hdd in raid
this will be the reason why my OS still worked, in RAID and in AHCI, and mij RAID configuration didn't
the OS isn't on the RAID, so is a reinstall necessary?
The SSD obviously is not part of the RAID array, but has been run in AHCI mode for a while, although the OS had been installed in RAID mode. So there may be some data even on the SSD, which cannot be detected by the OS.
So I recommend to do a fresh OS installation.

can i solve this problem by disattach (unmount, disconnect) the raid configuration in the intel RST interface, and reattach without loosing data?
You may try that additionally, but I don't know, if you will loose data. Do a complete backup first!
