I guess it's not a problem of the Areca controller since it's bios sees the
created drive just fine with the correct size.

That was badly stated, see my other posts. Booting from a grub disk still
won't work (grub doesn't see any disk)
as soon as i boot from an external usb drive all is fine and from the point
where linux boots I have full access to the drive. Seeing all available,
partitioned and unpartitioned disk space.

no windows here, debian/etch x86_64, being totally new to this i just found
that a few pages at MS explained basics actually quite good.
