Huge pre-delay needed for WDC 250 gig PATA drive?

even 10 sec. is not enough for my Intel 875PBZ to recognize the drive on
cold boot. Is that normal?

What delays are you guys using (owners of WD2500JB)?
 
No change. I tried with the standard 40 wire cable. I tried switching to
secondary connector. The problem follows the drive.

I called WD. They suggested the following:

1. remove all jumpers. This is their "single drive" mode. I had the single
drive jumpered as Master.

2. run their diagnostic software. It's running now (takes a long time on a
250 G drive!).

Thats likely it. You can get some odd results with the drive
jumpered as master when its the only drive on the ribbon cable.

now (takes a long time on a 250 G drive!).

Yeah, thats the main downside with the big drives.
 
WD HDs should be jumpered alone if they are alone. Master, if they have a
slave on the same ribbon cable.
It will probably work now if that's the problem.

80 wire ribbon cable is a must in any OS environment that utilizes UDMA.

That was it. Everything is normal without any jumpers.

Isn't there a standard practice of jumpering single drives as master? Why
is WD the only manuf. who does this?

This is what you get for buying OEM drives .. no instructions.
 
If you have access to newsgroups, you most likely have an internet browser.
Is it broke?

Nope.

I bought a 200g WD, and I recall there were several conflicting
suggestions for the jumpers in the various documentation. I went with
the label on the drive which corresponded to the config (someone
posted) WD support suggested.

I thought it was kind of odd, but I was lucky I guessed right the
first time.

I'd imagine a lot of people will be searching for jumpers when they
want to add a drive ;)

There isnt any good reason.


Bullshit, the label on the drive spells that out and the web site does in

spades.

I wasn't complaining about not having instructions with OEM drives. These
are cheaper than retail packaging.

There isn't enough room on the drive for all the jumper combinations,
(including those that make large drives look like 2 smaller ones, for older
BIOS and OS's).

In absence of any information, one tends to go with the "standard" practice.
When that failed, I looked up the WD web site and found the solution..

Standard operating procedure, but inconvenient .. and unnecessary (if WD
followed industry practices).

Sure.

Yes, but the label does show the jumper config for single drive.

In fact WD drives default to cable select now and
you can argue that that is standard practice now.

I always check the web site first, just because
there is a limit to what can be included on the label.

Sure. And you could have read the label on the drive too.
