I don't think the RAID is the source of the problem (although a
RAID controller that does not have a clear user interface and
good documentation is more than useless).

Can you recommend RAID controller manufacturers who do it right ?

If it wiped data, it
should have wiped the whole disks.

That's what I thought...

More likely the crashes are
the reason your partition seems empty. Microsoft is notoriously
unreliable handling filesystems (and why anybody put up with
that is a mystery to me....).

At the time (2 years ago) we choose the system, time constraints
led use to choose a Windows server. I hope I'll be able to replace
it by something more modular, open and reliable, someday...

Look a bit thtrough the archives of
this group. Numerous people had the same problem (partition under
windows suddenly seems empty). You will find numerous things you
can do in the answering posts.

That makes sense, at least. I'm gonna check. Thanks.
