My Toshiba Satellite A660 has been in for servicing quite a bit over
the last 8 months for ongoing problems, and it seems over them now. I
just managed to do a SMART report, and all seems normal except for a
rather large number that I'm not sure what to make of I already
followed the wikipedia breakdown of the parameters). I've attached an
extract of the report below, and I removed the VALUE column preceding
the WORST column because all the figures were the same except for #10,
Spin_Retry_Count (102 instead of 100). Also, #194,
Temperature_Celsius as the note "(Min/Max 24/53)" after the RAW_VALUE
figure. This edits are attempts to keep text rows below 80 characters
in order to avoid wrap-around.

What I really caught my attention was Power-Off Retract Count raw
value, 2293768. The normalized values seem to indicate that all is
well, and I tried googling typical values. The only hit that seemed
relevant is http://community.wdc.com/t5/Desktop-Portable-Drives/HDD-and-BIOS-detection-issues/td-p/359927,
which reports a raw value of 63.

The Load_Cycle_Count 3871 also seems high, but Wikipedia says typical
HDs can sustain 300K to 600K.

Further googling says that some linux systems can drive up the count,
but this is Windows 7.

Is the large raw number ignorable considering the healthy-looking
normalized number?

I've since had another Toshiba Satellite with a hard drive failure,
replaced under warranty, only just by one week, quite literally.

That's not really all that bad with a laptop.

Likely its just some quirk with how Toshiba chooses to do that
particular value, its not a simple count like some of the others are.

And according to wikipedia its likely the number of head retracts
that don't involve powering off the drive, so that's not at all unusual
for a laptop drive given that they do tend to do that for safety.

I don't see that one as relevant, because its not a Toshiba drive.

Not for a laptop its not. They do power down
the drive to increase the time on the battery.

Specially with laptop drives.

But is a laptop, nothing surprising about that with a laptop.

Yes, it's ignorable.
That's a fine, the drive is doing fine.

2293768 = 0x230008, which suggests that the actual count is 8 and
something else (decimal 35) is being stored in the high-order bits.

Higher is better.

Ah, yes. This is probably some funky count-down. Raw numbers are
tricky. I suspect the drive would long be dead otherwise and
it would definitely not have a coocked value of 100 (i.e.
perfectly fine).

for 2.5" HDDs typically 500'000-1 Million. 3871 is pretty low.

The problem with Linux (or rather the brain-dead HDD engineers,
e.g. at WD) is that Linux accesses disks every 30 seconds or
so. If the disk does a head retract after 25 secs, it gets
a lot of head-loads. I just barely caught one of my 2.5"
drives at 800'000 of them. Also google wdidle3 in this
group for more on that stupidity.

> Is the large raw number ignorable considering the healthy-looking

Depends. But from the raw output below, I would say your
drive is perfectly fine. There is absolutely nothing
even slighly suspicuous I can see.

But note that depending on the nature of problems, your
disk may be entirely innocent, even if it looks like
disk trouble. Bad RAM, overheating of other components,
bad power, etc. can all look similar to disk troubles.

I agree. And the cooked value of 100 suggests it is fine.

Boy, my attempts to avoid wrap-around failed miserably.

Sigh.

Thanks to you all, Rod, Robert, Arno.

Neat speculation on 2293768 = 0x230008 and the possibility that the
higher order bits might be used for something else.

I was think that the short idle times before standby might contribute
as well, but not in the order of millions!

I paid for the shipping the last 2 times. When you consider that the
only thing originally wrong was the HD....if only I had known, I would
have gladly dished out the heightened prices at that time to replace
it myself. That's how I would do it now. The reinstallation alone
for just one repair would have been worth it (I think I reinstalled
5~7 times times this year, including the 2 trips to the local place
and the temporary replacement machine they kindly provided).

Anyway, I don't mean to sound like I'm faulting Toshiba, they did good
despite mistakes. I had a good agent. For a while there, I had a
temporary stand-in who I didn't even understand (I mean on the
phone). I feel lucky despite the misfortunes.

Hopefully, you could replace the HD yourself. All my problems started
when I brought it into an authorized 3rd party repair place. Horrible
8 months. After bringing it back without success, Toshiba had me ship
it to their own depot. They did a good job, though it took 3 returns
to them to get rid of all problems. I think most of the problems that
occurred was due to rough handling during shipping. So even though I
don't trust the locals and I trust them, it's crap shoot when you use
UPS. The fact that they didn't take packaging seriously on the first
time was probably a contributing factor though (possibly the sole
factor -- I don't know).

No, had to use Toshiba because of the warranty claim.

This one worked fine the first time.

Sounds plausible.

Not clear what happened here, it was returned
by the retailer to get the warranty repair.

Legally they have to pay for it here.

Yeah, I would have with a mega disaster like that.

Just had someone else buy an i7 Toshiba, it will be interesting to see how
that goes.

I'd be interested to hear about that too. I spoke too soon about all being well. The "k" key is starting to stick, and it's freaking annoying when you're trying to quickly compose messages. Makes me wonder if they replaced it with a new keyboard with a used/repaired one, or simply rushed the jobs. Perhaps the design isn't service-friendly, or perhaps the overall quality simply isn't good. At this point, I have lost any sense of charity with regards to benefit-of-doubt. I simply do not care anymore what the exact cause is, and in truth, I don't think it matters what the freaking cause is anymore when so many time-demolishing negative experiences are encountered one after another with no significant periods of trouble-free usage in between.

My next model will in no way be by this vendor, and if the "k" key is any indication, this will happen sooner rather than later.
