Im sorry that this post is off topic, but I find this NG to be the most knowledgeble on just about everything computer\nrelated. I just got my 160gb SATA HD, and while usually the drives will have a diagram on them to show where the jumper\nshould be for Master, Slave etc, this one doesnt. It has 2 rows, 4 across. The Jumper is vertically positioned on the 2 on\nthe far right. The only diagram on it shows the jumper on the 2nd set from the right side, and says "PM2 Enabled".\n\nI want to run this drive as Primary MASTER on my MOBO. Is the setting correct already? Its a WD1600JD.\n\nThanks..
