HD only recognized in dual slave mode

  After cloning the old Seagate HD to my new ATA Caviar Blue 160 with the free WD cloning software I took out the old drive and installed the new one on the first set of connectors where the original one was. The only problem is the compter will only recoqnize the WD Hd with the jumpers set for dual slave mode, all the other positions the computer won’t boot up. What gives? any ideas why?

  I can use it as is but wonder what went wronge, or if there is a performance issue or not. The WD HD was recognized and cloned with the factory settings for the jumpers.

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.

 I resolved it. Apparently the original HD was not on the right set of connectors ( the end of the cable), once I reconnected it and put the jumpers on the first two pins it booted up as a master.

Thanks
