My (SAMSUNG Black 20X DVD+R 8X DVD+RW 16X DVD+R DL 20X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA 20X DVD Burner with LightScribe LightScribe Support - OEM)connected to a PCI SATA card didn't show up at all. I finally found the TSST Win Inquiry tool to determine it was really called a "TSST corpCDDVDW TS-H653N" I probably don't need drivers for my optical drive but it wouldn't work at all until I fooled with it for weeks and applied a firmware update, which I was able to find. It is workng now, but driver is Microsoft 2001 and doesn't display correctly in Device manager. Google of TS-H653N turned up a driver (ts-h653n-driver.2.4.1.zip) at: http://www.bioticaindia.com/. I tried to register yesterday to two e-mails and haven't gotten an activation from either one so I could download this driver. Finally to my question, does anyone know where to find this driver.
