From: fbsnr on 27 Jan 2006 23:42 I have an old Samsung SC 148F CDROM drive, which may need to be re-jumpered as I'm adding an ATA drive to the cable. There are 3 pairs of pins on the back of the device. The trouble is that there are no markings on the CDROM drive to tell me which are the master jumper, slave or CS pair of pins. Does anybody actually know how to identify which pair equate to the above positions..

There is a manual here, but it might not be the right one. http://www.samsung.com/download/FileView.aspx?cttfileid=162690&type=CD+%2f+DVD-Rom&typecode=13&subtype=CD-ROM+(Half-Height)&subtypecode=1301&model=SC-148F&filetype=UM&language= That short document shows: C S M S L A X X X X X X and that is looking at the connector on the back of the drive. On some drives, the legend is stamped into the metal on the drive casing. It is possible you might also see some labelling on the PCB material. I think I own one drive that has nothing on it, so it does happen. Paul
