Okay, so I lost one of the really tiny jumpers on my HD, it still works with no jumper on it, but....how do I get another jumper for it? Will the manufacturer actually send me a single jumper..or can I run down to Fry's electronics or something and pickup a random jumper?
 
SEAGATE, 250GB Barracuda 7200.10, SATA 3.0 Gbit/s, 7200-RPM, 8MB cache

That's the HD I have that I lost the stupid jumper for.

My other question is...are all jumpers created equal? Can I steal one from a completly different drive?
 
You don't need a jumper for a SATA hard drive, as each drive operates on its own independent channel.

If you're really picky about it, you could probably ask a nearby computer parts place for a jumper for the hard drive.
 
So, SATA drives don't use jumpers at all to distinguish between Master and Slave? Is there any reason why they came with jumpers then? o_O?
 
One of the major reasons for jumpers on SATA hard drives is to allow the SATA/300 (3.0GB/s) hard drive to operate on a motherboard that has SATA/150 (1.5GB/s) ports. (There are other reasons, but they largely depend on the particular hard drive model in question.) If you have a motherboard that has SATA/300 ports, chances are that you don't need to worry about the jumper.
 
Well, here is why I ask...currently I have 2 of the same HDs, connected to a raid card in raid 0. I took the raid card out and put both HDs into the mobo sata ports, and when I went to re-install Vista, it was only detecting one of the HDs, however both showed in the BIOS. Was Vista just not seeing it due to the drives being in Raid 0 previously?
 
Vista didn't see one of the drives? are you sure? It should have detected all physical drives, regardless if they were previously setup in a RAID array.

Tiraides is correct, Seagate uses a jumper for SATA150 compatibility, but it is typically not required, especially if you have SATA300 controllers.
