Corse they can but they arent that stupid.

I'm using the small, freeware SMART monitor at
http://www.beyondlogic.org/solutions/smart/smart.htm if anyone is looking
for one.

They could, but probably don't.

However, Maxtor do something like that with their OneTouch drives.

Guaranteed to overheat and fail loooooong before the warranty runs out.

RMA will do the same.

They could, but it would be illegal in many places. And it
is not like the evidence would be hard to obtain.

Shoddy manufacuting, bad QA, bad cooling (as Odie pints out
elsewere in this thread) are all acceptable. Deliberate,
planned destruction is not, unless the customer is told very
clearly when it will happen and what will happen. It may
still be illegal if there is no good technical reason for the
limited lifetime.

Having a HD continue to operate after its warranty period is over may
represent a loss in potential new revenue to HD manufacturers.

I tried WD's SMART monitor (DLGDIAG), and my firewall caught it trying to
connect to the WDC.com site with some of my drive's information.
What are they trying to do?

So does a reputation for dying once the warranty has expired.

And its illegal in all first world countrys anyway, and
trivial to work out that the manufacturer is doing that.

They wouldnt be that stupid.

Maybe collecting usage and reliability data on their product? If so,
informing the user, even asking permission, would be courteous.
Instead they're likely to create suspicion, paranoia and bad press.

I agree. Unless the cutomer moves its business elsewhere as
a result of this.

Interesting. And potentially criminal in Euroope.

For hardware to have a fixed and limited life, you would have to be
buying a licence to use the hardware, rather than purchasing the
hardware. In order to do buy a licence, you would have to agree to the
conditions, like you do before you use software like when you install
Microsoft software.

Mean Time Between Failure is just that, a mean, an average, so some will
get 50 percent of the mean time and some will get 150 per cent.

I have not had much experience of the purchase of mainframe hardware,
the only case I was close to, the company I worked for paid Honeywell
for an annual licence for the operating system and for the hardware. If
the fee had not been paid the hardware and operating system would have
ceased to work. This was however upfront and part of the original
purchase contract, and was therefore legal.

While that is true, having them fail like clockwork at the end of the
warranty period (which is measured in calendar time and not operating hours
by the way, so I fail to see how a power on hours count can reasonably be
used for this purpose) and having that traced to deliberately implemented
firmware counter would cost them far more in legal fees, court costs, and
actual and punitive damages than they would be likely to make by selling a
few more drives.

Was it in fact providing information or was it, perhaps, checking to see if
there was an update available?

Regardless, might have been gathering statistics.

I had a friend help me analyze what they were trying to do.
DLGDIAG connected to websupport.wdc.com and sent the following information
to them via HTTP without my approval:

serialnum=[my drive serial number]
model=[my drive model number]
manufacturer=[drive manufacturer]
firmware=[version number]
result=PASS
LastTest=[Day] [Month] [Date] [Year] [Time]
Date=SMART_STATUS
EID=0
EDATA=0

Aha, seems to be statistics gathering. No personal information.
Still not nice to do without explicitely asking you for permission
first.

It's a bit more complex than that. While there's no personal information as
such included, the information is unique. This is akin to tracking cookies.
Not a big deal, as you're probably not running it often, but still...

OTOH, maybe there's something in the license or readme file that tells you
that it does this? Did you check those?

True. It does not make this outright illegal in Europe, I think,
but it is borderline. Only if they can identify the user from the
serial number, then it would be likely illegal here.

As far as I understand US law (IANAL), that would make it probably legal
over there, even if they can identify users from serial numbers. It
would change nothing in Europe, since you have to actively allow them
to gather and keep personified data.

Are there people who register the purchases of their hard disks? Sounds as
if WD provided a means to register hard disk purchases (with serial
number), this would make it illegal.

Do HD manufacturers have rebates in Europe?
HD rebates are popular in the U.S., and the manufacturers get your name,
address and drive serial number in the process.
So they know who I am from my drive serial number.

Not that I am aware of. Manufacturer rebates would be against the law in
many (all?) European countries, since they obscure the true price to the
end-user.

Hmm, bad! I think the US needs better privacy laws urgently to keep
the likes of WD from snooping secretly.

No they dont.

And rebates are seen in europe, even if not common with hard drives.

Nope.

Mindless bureaucratic silly stuff thats one of the main
reasons industry in europe is so uncompetitive.
