Thanks for your message and confirmation, glad to hear that now things are working!
Just to help other users, I write the message to here also, as it can be helpful if some information is missing:
The issue may be related to the fact that certain detection routines (which required to access SCSI / USB / RAID arrays) of Hard Disk Sentinel disabled. This is why we do not see anything, just "Hard Disk Device 0" and so.
I'd recommend to open Configuration -> Disk Control and un-check "Disable detection of USB and SCSI drives"
This way the complete status information may be quickly detected and displayed (again). It may appear immediately but it is possible that a restart required, depending on the configuration.

On special RAID controllers (like this one) usually the power management of the hard disks are managed completely by the RAID controller.
I mean that (for example) if you configure Windows to power on hard disks after a period of time, usually the RAID controller ignores this and manage the drives by its own settings.
For some situations, to keep the drives spinning (preventing from entering sleep state or parking the heads) it is a good idea to use the Configuration -> Disk Control -> Do not allow spin down of hard disks
field: enter a *
in that field. This way Hard Disk Sentinel periodically send a command to all hard disks, preventing them from entering sleep state and keeping the drives active (without decreasing performance of course).

Me thanks too, glad that I could help
