bloody SATA connectors (electrical)!

That's what you get if you buy drives intended for backplane use.
Buy the ons intended for desktop cases, those with regular Molex power plug.

Have you ever seen the SATA drive with old-ATA-style 5pin large power
connector?

If yes - can you name the models? I have only seens the SATA drives with new
style power connector, looking like the SATA data one but wider.

I don't think there ever were such drives. There were some that had the
traditional 4 pin molex connector in addition to the SATA power connector.
Some early Seagete models I think.

The new Western Digital SATA2 KS series of drives have
both SATA and standard 4 pin Molex connectors.

Is the usual disk/CD power connector 4pin or 5? Sorry, do not have this at
sightseeing distance, only remember that it has +-5V and +-12V (and maybe
ground too?)

4 pins: +5v, +12v, ground, plus the 4th pin which is also sometimes
ground (but may sometimes be unconnected, I think - at least one of my
USB external power connectors is IIRC)

i agree and have purchased WD SATA drives
for that very reason

my Seagate Barracuda SATA drives only have
the SATA power connector. :(

but it goes beyond just the damn lousy
power connector, it also applies to the
bloody SATA data cable/connector

+5-GND-GND-+12, i.e. 4 pins. SATA requires also 3.3V, but most drives do
not actually need it at the moment.

Bullshit, as always from the babblebot.
There is no such requirement.

Because it's usually generated from the 5V internally.
Drives that don't use 5V will obviously have a problem if it is used with a
PS that doesn't supply 3.3 V at the Sata Power connector or are used with
a SATA to Molex converter cable.

It shouldn't be a problem if you harness that data cable properly.
Cables should never run loose in any case.

How strange when below you just say they work utterly fine when used as intended.


Gee, what a surprise: you are using them as intended.

So you're saying, that all the PC solutions out there where the
power/data connectors go directly into the drive as opposed to a
backplane are not using SATA drives the way they are intended. If that's
the case, then perhaps you could provide a cite for this claim, since
pretty much every commercially available PC with SATA drives are
configured with direct connections from the motherboard to the drives
with no intervening backplane.

My 160GB WD 1600js SATA II drive has both molex(4-pin) and sata power.Not
sure what you mean about old style 5-pin?

I did?
I said that *you* were using the drives that *you* bought
(with backplane type power connectors) as 'intended'.
I said nothing about *all* Sata drives.
In the other post I specifically said to use drives with regular
molex power connector if you are not using them in servers or
other systems that use backplane type connectors or cages.
If that's the case,

First, if you want get all superior, you might want to look up
"apprehension" and "comprehension" in a dictionary!

Second you seem to be claiming that the PC systems from vendors like
DELL etc all use the 4-pin power connector (since they don't come with
SATA backplanes), and if they don't then they are not using drives the
way they are intended! I must say that hasn't been my experience. Also,
I've bought a whole lot of SATA drives in the last few years and I've
yet to see any indication on the box as to which type of power connector
I'm getting. Surely if the SATA drive vendors intended this distinction
they would make it clear on the packaging, which they don't.

Personally I think you are pulling this out of somewhere south of your
navel, and that drives with 4-pin power connectors are there for people
who have PSUs that don't have SATA-style power connectors. By the way if
you are right about this, care to explain why modern PC power suppliers
have SATA style power connectors?

Nik,


Please don't wind Folknutter up.

Laughter is most definitely the best medicine, and his posts crease me
up no end.

I love them! The most hilarious poster on usenet, as far as I'm
concerned!

Read them, learn to live with them, realise the desperation in them, lay
back and laugh!

*Please* don't spoil my fun by chasing him away - he's precious.

Hehe. No chance of that. The only thing I really admire in Folkert is
his persistence. Truely amazing.

Uhuh. Like you did, eh Nikki?
Obviously not.

Sounds to me that the use of 'reading apprehension' was totally appropriate, Nikki.

And now you know exactly what moves the odi(e)fe(r)rous, 'the stinking one'.

Sounds like a perfect description of yourself, babblebot. To a T.
Have you been gazing in that mirror again? I told you to stop that.
 
I note you failed to address any of the points I made about SATA power
connectors. Just in case you were having comprehension or apprehension
difficulties, I'll restate them for you...

If drives with SATA-style power connector are not to be used except in
backplane type situations, how come:

1. Why do the drive vendors make no attempt to distinguish between those
drives that require SATA type power connectors and those that don't on
the retail packaging?

2. Why do modern PC power supplies have SATA type power connectors as a
standard feature?

3. Why do major PC vendors ship drives with SATA type power connectors
without worrying about putting a backplane in for the drives?

Come on you're such smart fellow, entertain us, give us an explanation!
