Library is in invalid state

[stab99z22]

I get the same error on some of my libraries. I have read that the cause might be that I upgraded some my hard drives in my server, and that has caused this issue (even though most, not all, of the content are in folders named the same and with the same drive letters).

I haven't found a fix for it yet - perhaps a total fresh install and new library database will help, but I haven't done that yet...
