I just replaced 1 Maxtor and 2 Seagate hard drives with Western
Digital. All are internal 3.5inch, 7200RPM, 8MB cache.

The replacements were made based on SMART data on the drives read by
www.grc.com SpinRite application. The Seagates and Maxtor
(manufactured by Seagate) all reported massive Seek Errors, ECC
Errors, Write Errors, and others that I don't recall. One of the
Seagate drives was only 1 month old. I contacted Seagate on the new
one, and was told to send it in for warranty replacement. I received a
refurbished drive that had more errors than the one I sent them. YIKES
- no more of this. The Seagate and Maxtor drives were all under
warranty, and I chucked them.

I now have 4 Western Digital drives. Not one is reporting any SMART
errors; the oldest one is a 40MB and has over 30,000 hours reported by
SMART data.

Is this a fluke? Does Seagate make defective drives? Does Western
Digital report SMART data correctly? I am a bit suspicious since none
of the WD drives show any SMART errors.

Nope.

Certainly some of them do die, just like with any manufacturer.

Yes.

Post the SMART reports that Everest produces.

Seagate has turned out some really bad drives lately. They used to be
dependable, but no more. Maxtor is owned by Seagate.

With seek errors, you can have external sources, such as a bad PSU,
though. I would be surprised to see seek errors in three different
drives at the same time without an external reason.

The ECC errors (ECC recoverd) are normal. Drives do not to
a precision seek on reading and often need to apply ECC
or re-read. ECC is faster these days. Write errors are
troubling, but can be the result of seeking problems.

Aha, that must be it.

Utter nonsense.

No. Really? Who would have thought, eh.

Clueless, as always.

Seagate drives appear to report big numbers for these parameters.

Here are some examples.

Good 120GB Seagate HD:
http://www.users.on.net/~fzabkar/SmartUDM/120GB.RPT

13GB Seagate HD with bad sectors:
http://www.users.on.net/~fzabkar/SmartUDM/13GB.RPT

Good 6GB Fujitsu HD:
http://www.users.on.net/~fzabkar/SmartUDM/6GB.RPT

See this old post of mine where I attempted to make sense of my
Seagate SMART data.

Seagate SMART, Raw Read Error Rate, Seek Error Rate
http://tinyurl.com/38nxmj

My testing suggests that the Seek Error Rate number is actually a
count, not a rate, and it appears to count seeks rather than seek
errors. Hence it comes as no surprise to me that your refurbished
drive has larger values for these parameters.
