Hi,

You have 4 hard drives connected to the IDE RAID-0, correct?
If yes, you can't access the drives directly via "\\.\PhysicalDriveX".

I'd suggest you using the ImageFile plug-in to create virtual file-based target(s) over the RAID-0.
Best regards,
Valeriy

X=? 4?

Or Just Use X?
It seems my answer was not so clear. :(

I mean you can't share RAID devices with the SPTI mode.
Ever if your RAID device is visible to the system as a single drive, it's impossible to share the system drive in Read/Write mode.

That's why I suggested using ImageFiles instead of SPTI.

FYI ImageFiles support clustering while IDE drives mapped with SPTI - do not.
Best regards,

But another kind of similar software could do that

They probably have single shared basic images and all changes are written and stored per-client.
According to your case, if you have 2 separate hard drives in your PC, the non-system one may be shared as R/W-enabled iSCSI target.
If you have the only hard drive (ever a hardware RAID) - StarWind does not allow sharing it in R/W mode to prevent your system data from corruption.
