Just put a WH14NS40 in our HTPC (Biostar A75MH mobo, A8-3850 APU, 8Gb DDR3-1600, Samsung 830 128Gb SSD, Win 7 x64).
Drive doesn't always seem to "see" a disc (so far just DVDs, retail and DVD+r). Sometimes reinserting the disc works, sometimes not but will work after I reboot HTPC. Tried with VLC, Windows Media Center and PowerDVD (paid version).
Drive at fault or ......?
