One drive hotter than the rest; write errors but no S.M.A.R.T. errors

[Percival P. Cassidy]

I have four Seagate ST32000641AS drives (plus other Seagate drives) in a
FreeNAS machine. One (only one) of those drives shows write errors from
time to time but no S.M.A.R.T. errors. Now I notice that that one drive
is running at 5 to 6 degrees C hotter than the others (35C vs. 29C or 30C).

What are my chances of getting it replaced under warranty (2+ years to
go) with no S.M.A.R.T. errors?

Is SeaTools likely to show errors that S.M.A.R.T. doesn't? (I'll have to
install the drive in another machine temporarily to run SeaTools for DOS
or for Windows.)

If they are CRC errors, it's likely to be the cables, not the
drives.
All my Seagate HDs that have run hotter have kerplunked sooner
than later. But Seagate will not replace them unless you have some
pretty drastic smart errors.

PS according to the "specialists", HD temp does not influence
durability. That has not been my personal experience, which is limited
to only 10 or 20 drives. So I'm no expert.

That isnt possible, you must not be reading the SMART data properly.

Now I notice that that one drive is running at 5 to 6
degrees C hotter than the others (35C vs. 29C or 30C).

Its very common that some drives get
more airflow over them than others
and clearly the end drives don't have
another drive on both sides of them.

What are my chances of getting it replaced under
warranty (2+ years to go) with no S.M.A.R.T. errors?

Really depends on who you make the warranty claim with.
If you just claim that it has stopped working, some will just
exchange the drive and assume its got an intermittent fault.

Is SeaTools likely to show errors that S.M.A.R.T. doesn't?

No, in fact it can claim that the drive is fine
when the SMART data shows that it is not.

(I'll have to install the drive in another machine
temporarily to run SeaTools for DOS or for Windows.)

Post the SMART report for the drive that you believe
is getting write errors and use Everest to do that.

FWIW, I have always found Seagate reasonably willing to replace
problematic drives. I'm curious about the circumstances causing you to
believe otherwise.

30 to 40 reallocated sectors was not enough to get my drive
replaced. It broke a few months after the warranty expired. (and a few
months after the bad sectors started appearing).
Seagates have 1, 2 or sometimes 3 year warranties. I have not
figured out why so much difference between models.

Ich they check anything, zero. If they just replace the drives
without checking anything, 100%.

SeaTools just queries SMART.

SeaTools just queries SMART.

The short test queries SMART. The looooong test is a surface
test, I've had it fail when the SMART test is OK.

Quite a bit of the time is lines that have been
continued from operations they have bought.

You don't have any heat errors wait till you get some think like my Ext
USB Segate drives 45c to 55c they are not flitted with a fan to cool
them or a metal box to get rid of the heat, I will never ever Buy a
Seagate again..

I'd say not very likely.

The long test is a SMART long selftest that any reasonable
SMART tool can run. There is no reason to use Seatools.
