Hello przemmo,
I looked at the Devzone about the Desktop PC Hardware Requirements and it states that the problem has to do with size and the type. I have added the paragraph that deals with this issue below:
All LabVIEW Real-Time versions support Parallel ATA in IDE while LabVIEW 8.5 (and above) and LabWindows/CVI RT 8.5 (and above) support Serial ATA only in AHCI. LabVIEW Real-Time and LabWindows/CVI RT versions prior to 8.5 do not support Serial ATA. LabVIEW Real-Time 8.6.1 and previous supports hard drives up to 126 GiB. LabVIEW Real-Time 2009 and above support hard drives up to 1.99 TiB. The following options may be available depending on the specific desktop PC.
