New SATA drives using jumpers??

[CE750]

Over the next month, parts of the MacPro order I just did will start to come in. Today, I got 3 hard drives (a 74GB Raptor, and 2 Deskstar 500GB) that I plan to put into the MacPro.

The computer will itself ship with a 500GB in bay 1, and that is going to also contain the OS.. My goal is to replace that one with the Raptor for my system/OS drive and then use the 3 500's for storage (two in RAID 0).

The problem is the drives all came with no jumper pegs.. the Deskstar has nothing anyway by way of jumpers, and the Raptor has 5 sets of 2 pins, but again, no peg.

The Raptor I have in my current Dual G5 does I recall have a jumper set..

I wonder, do these newer SATA machines require jumpers?

No?...

If they are SATA - no jumpers at all. Each goes on a separate channel.

I am being told that it's plug and play now with SATA.. and if I understand your reply.. that information is correct. Great news, I love plug-n-play technology.


Thanks.

There are jumpers for SATAII and SATAI though are there not? At least depending on the drive make

No jumper = SATA2 (3GB)
Jumper = SATA (1.5GB)

The deskstar has no jumpers, and the Raptor has them (but nothing is jumpered).. so am I to assume the Raptor is also a "no jumper" needed drive? Has the raptor changed at all in the past 2 years? my last one was jumpered I recall.

another qoute for you today

edit: also the op is an asshole for having a rig that nice ::jealous:: when cider is realeased you should be able to play games on mac os x for now i bet you are dual booting with windows? I would of considered getting the mac pro if it came with a single dual core processor so I could afford it even than i'd have to put a graphics card and ram in. I than decided when it came out i wasn't going to get a Mac Pro

SATA hard drives don't use jumpers 'cause they all operate on their own channel. Does the back of your raptor look like this?

 

[Budman]

no master/slave so no need for jumpers.

This is confusing - are the cited jumpers to chose between SATA I and II? What are they for? And, as an aside - why must some resort to name calling? That's not cool.

Yes basically, I believe the reason they have jumpers for selecting between SATA I and II is because the manufacturers were too stupid to think ahead so that the technology could accomodate advancements in the bus speeds etc.. It's really pathetic that despite how new SATA I and II are, they've had to resort going back to jumpers again with the second revision, when SATA V is out, I'm sure we'll have 5 jumpers then again...

(If you guys remember at all, back in the PATA days when faster buses came out, all you had to do was plug it in and set the drive to slave or master, there weren't any speed selections or anything stupid like that...

Pretty sure all Raptors are SATA1 1.5GB/s and thus they don't have an SATA1/2 jumper.

If this is the case, they should have a jumper according to Baked.

No jumpers on any SATA drives. The pins are mainly there for debug purposes.

1.5 and 3G terminology are preferable to non-existant "SATA II" which was the former name of the standard committee and not the specification.

It is not required to install the jumper to limit to 1.5G unless there is a problem. For a volume builder that may mean it is (or was during the transition) worth testing and if the combination of drive and controller passed then not bothering with the jumper while the home user may as well install it if they know the controller is not capable of 3G in order to preclude a problem (certainly just installing the jumper on a drive or two during installation is easier than worrying, let alone actually encountering problems and having to do it later anyway).
