I have a 1-TB drive that I installed in my desktop as my master drive. I would like to add (2) Western Digital Caviar SE WD2500 SATA. One as a second master drive and the second and the slave to the second master drive, but I am clueless as to the pin/jumper settings for these 2 drives.
Any input??

For details on setting jumpers on IDE (PATA) drives, see my post dated today (11-05-2009) in this thread:

http://www.tomshardware.com/forum/273978-31-settings-in...

It is focused on a person who had IDE drives and needs to move them from
external to internal connections.

BEFORE you do all that reading, answer this: are ANY of your drives IDE (PATA)? Because with SATA drives (and you say BOTH of your new drives are) THERE IS NO MASTER TO SLAVE!

So without any doubt, you do NOT set Master or Slave on the two new SATA drives, and you probably do not want to change any jumpers they have.

The older 1TB drive you have MAY be on an IDE port as the Master (set by jumpers) of THAT PORT ONLY, or it MAY be a SATA drive, too which in fact is NOT a Master of anything.

What I suspect you mean is that you have an existing 1TB drive (probably SATA, but does not matter) that is your BOOT DRIVE called C:. In your Bios Setup screens it should be set in the Boot Priority Sequence as the device to boot from (maybe second choice after your optical drive). That make it your BOOT drive, not your Master drive. From there you want to add two new SATA drives on their own ports. Unless you specifically Partition one or both as Bootable Drives and install some Operating System on it (them), both will simply be drives to used for data. Neither will be Master of anything.

On SATA drives, unlike IDE's, any jumpers present are NOT used for Master, Slave, etc - there is no such thing for SATA. There ARE jumpers on some SATA drives (I thnk WD inits have them) for other purposes. One jumper is used for uncommon cases where you need to force a newer SATA II drive to slow down for compatibility with an older SATA controller. If you KNOW your controller is also SATA II, you can set that jumper to run at full SATA II speed. Most other jumpers are things you do NOT want to change, so leave them alone.

paperdoc,

I have an older WD1600AAJS with windows xp/sp3 installed. Windows went bad and I tried to repair it. Did not have good luck so I bought a WD
5000AAKX and installed my OS using the OEM disc. I got windows to work in safe mode on the old hdd and I want to slave the 1600 to the 5000 to transfer my data. Both Hard drives are SATA and neither of the have jumper labels. There are no shunts in either unit but I have a few of those. I have searched for hours and the only thing I have been able to find that is close is to jump 5-6 on master and 7-8 on slave drive but that is not specific to my drive model numbers. Can you get me any closer?
