I’ve noted an interesting behaviour where Data Lifeguard Diagnostics for Windows v1.24.0.0 is listing certain drives with " (USB)" at the end of the Model Number field (when they are not attached via USB).
The drives in question (tested with WD3000HLFS, WD3000HLHX and WD2002FYPS, as well as reporting non-WD drives attached in the same manner with the same suffix) are connected as follows:
Drive → AIC XJ3000-4243S ( http://www.aicipc.com/ProductDetail.aspx?ref=XJ3000-4243S) → 2M LSI/3ware SFF-8088 to SFF-8088 cable ( http://store.lsi.com/store.cfm/External_Multi-Lane_Cables/All_Cables/CBL-SFF8088SAS-20M/) → LSI 9200-8e (8-Port SAS/SATA 6Gbps HBA) x8 PCIe 2.0 ( http://www.lsi.com/channel/products/storagecomponents/Pages/LSISAS9200-8e.aspx) → x16 PCIe 2.0 slot on motherboard (ASUS M4A785-M)
The system in question is running Windows Server 2008 R2 SP1 Enterprise (64-bit)
