Has anyone had their 36gb WD Raptor fail? One of my 14 month old
Raptors has just died. Click Zing, Click Zing six times and then spin
down, even with the data cable disconnected. With a quoted
"Unsurpassed Reliability: 5-year warranty and 1.2 million hours MTBF",
I am a little surprised it went after ~ 5000 hours (425 days * 12
Hours). My box is well ventilated and the drive stack runs cool to the
touch and this is the first drive failure I have had since the IBM
DeskStar days.
I did a Google search for other Raptor failures but did not find any.
WD gave me a hard time about warranty replacement, said it was an OEM
drive and to go back to the vender. Newegg.com clearly states warranty
by manufacture and WD finally relented and sent me a replacement (
still waiting to arrive, shipped in two days but still waiting for UPS
ground for a week). Just wondering if I should consider RAID 1 even
though I ghost every other day.

I dont see the problem! It has a 5 yr warranty and you got a new drive. Did
you expect the drive to die at 1.2milliion hours + 1 second. The MT of MTBF
is Mean Time between failure.
I think that drives suffer from the "bath tub" failure curve ie lots at the
start (we hope the manufactures catch these, and lots at the end (old age)
in between there will be a small number that will die every so often. I have
said before that there are only two types of disk those that have died and
those that will! the trick is to pass on the disk / system to someone else
before it dies!!

Other people (in mags) have said that any RAID with less than 3 disks is not
worth having (in RAID1 how do you know which disk has the good data and
which the bad if things start to go wrong? ie not a total loss of a disk and
if it starts to rebuild the array with the duff data!!).

Me I go with RAID 5 on 4 disks. So I now have four dsiks that can fail
:-( ( and backup to other media) it all depends on how much you "need" the
data and when! Can you do without it for hours, days, weeks. If the PC gets
stolen can you still recover from this? Only you know how much the cost of
time and effort as well as money is required to make "you" happy.

That's nonsense. Two drive RAID 1 is very effective.

Huh, one drive will be reporting read and/or SMART failures and the other
wont. The non-failing drive becomes the dominant.

> Me I go with RAID 5 on 4 disks. So I now have four dsiks that can fail

Yep, if two drives fail then you've lost it all.

I've had it with hard disks failing - hardly any make past the end of the warranty! Tried all the makes, they all get really hot and wear out. Got myself four of em now - a stripe/mirror set, each with cooler fins attached.

You say "425 days" - that's over a year - never heard of a retailer doing over 1 year! 1 year - end of warranty it's up to the manufacturer surely?

Just wondering if I should consider RAID 1 even

Any raid controller worty of the name will tell you which disk is
failing. Even the Promise controllers on motherboards tell you that
much. Leastways the ones in the two machines I built for the office
have done so when a disk when tits up in both of them recently.

Very good point ted These are the sort of calls people should make
when deciding Backup/redundancy stratagies It's fat too easy to spend
serious bucks on this sort of thing when in reality the value of the
data held is in the cold light of day not really that "vital" after
all.

I agree that the theory says you "should know" but if I can quote in part
from an item in PC Pro (UK) nov 2003 by Steve Cassidy, in talking about
RAID failures...
"I have never, ever, encountered a mirrored RAID setup that worked as
advertised"
"The gotcha isn't in the theoretical design, but rather in the failure mode"

He goes onto say that while the systems might say they are working OK behind
in the background they can be writing all sorts of duff data to the mirror
before they fail.

He says that in effect you get what you pay for, big expesive RAID cards are
"good" if you need data 24/7 and simple on motherboard systems/cards are
good if you wish to feel good at being with the "big boys" but dont think
you will get the same level of service from the system if things go AWOL.

As a caution, in the company I worked for a few years ago (no names!) "we"
had a system with an expensive RAID setup but the email notification of
errors was not set up no-one had any idea that the RAID 5 had lost one of 4
disks until the second died, ho hum! (backups are great when they work!!)

My dad worked for a company that had major data loss. They didn't verify
the tape backup and it turns out the tape drive hadn't made a valid backup
in months or years-didn't throw an error message either. As far as raid
working or not, I try not to consider raid a backup solution, just a more
robust storage method.

There are some people here that positively seem to hate anybody with
true competence or insights. Possibly because they try to impress
people with half-knowledge and those that truly know make it
hard for them. Indicators are e.g. the lack of manners, the
putting down of things said with no or insufficient explanation,
the classification of some people (e.g. me) as "trolls" and the
often amusingly naive technical opinions.

My solution is to mostly ignore them. Works well.

people are called trolls for a reason?

Getting back to the original thread, received the replacement drive
and installed. It is a refurbished drive and that is ok, but boy is
this drive LOUD. It is out of balance, shakes the whole cabinet. It is
MUCH louder than my other two Raptors and gets much warmer to the
touch. I had to remove it from its normal mounting place and place it
on a piece of foam rubber in the bottom of the case otherwise it
causes the side panels to buzz and rattle.
Heat and vibration are the two things that can kill a hard disk and
this drive generates both on its own. I was afraid it might hurt my
other drives, so yet another replacement is on its way.

Blowing your own trumpet again, Arnie, since noone else does it for you?

> Possibly because they try to impress people with half-knowledge

The sort of half-knowledge that Ultra DMA mode 2 doesn't have CRC
detection, Arnie? That ATAPI command set is much simpler than SCSI?
Like IDE-flashdisk somehow not being removable flash disk?
That glass platters can be bend, like a pretzel?
That Command queuing is only in the next SATA standard?
That the DOS drive letter system is braindead?
That only IBM can unlock Travelstars?
That the IDE interface specification does not support
an unpowered drive because of short circuiting?
Hot-plugging is a newer trend?

That sort of half-knowledge, Arnie?

> and those that truly know make it hard for them.

Sounds like a pretty good description of yourself, Arnie.

> Indicators are e.g. the lack of manners, the putting down

Like "Expect it to die soon", Arnie?
"Obviously you don't know how a modern differential junction temperature sensor works", Arnie?

Which of course you are when you admit to litter your
messages with typoes every time, " to keep us happy".

Poor Arnie who hasn't got the sole right to do that himself.

Ofcourse it does.
Why draw more attention to yourself when you had to be
corrected once again, right, Arnie "babblemouth" Wagner?

This guy has a _list_! ROTFL!
I must be a real threat to him!

Not that everything on his list is actually a mistake and disregarding
that a zero-mistake requirement is completely unusable to identify
competent people...

Challenge and you might get what you don't wish for.
Actually, you are giving yourself more credit again for something that
sits in my Sent Items folder for free. I only have to run a search on

Actually I stopped at 1/3 that list, Arnie. There was lots more.
You are miles away from zero-mistake and hardly competent.
