Hwinfo does not display my ancient Promise TX4650 fake-RAID SAS controller in disk list (neither as single huge disk or as separate disks). The connected disks are Sun/Oracle branded 3Tb Seagate Constellation ES2 (SAS interface).
For comparison, here is screenshot from Speccy, which displays it correctly, but have many other issues.
