[SOLVED] - Uncorrectable Sector Count: 112

Admin

& current pending sector count: 112 (linked?)

Does that mean that 112 sectors cannot be remapped?

Constant high HDD usage.

Computer is very slow despite being newer with nice specs (7th gen i5, 8GB DDR4).

Put in an SSD with a fresh installation of Windows?

That means you have 112 sectors that have been identified as bad, and are waiting for re-allocation. That won't happen until the sectors are written to, as the firmware assumes data may be needed, so it won't remap until the OS marks the area for deletion by writing to it.

112 is high, replace. The high disk use is Windows trying to read data and having errors most likely. If you check your event log you may see errors related to the disk.

Fresh installation of Windows or clone?

Depends. If user is ok with fresh that is better for stability, you know you are not migrating corrupt files unless it's personal data, in which case can't help that.

1 would be high, replace!

ANY hard drive problem is an automatic replacement with me. HDDs are too cheap to mess with, it's faster to clone then the cost of my labor to work with it. SSDs are still more expensive but the massive upgrade in speed is also worth the time there.

^^^This. Given the size of drives these days, which means they take much longer to scan/check/data transfer/backup/restore, and the low price it's a no brainer in my book to just replace when there's even the slightest whiff of a drive problem.

Well, yes and no.

You are essentially expecting perfection from your storage media, which just isn't going to happen all the time.

I agree that a large error count does warrant a look, but that is what spare sectors are for. I've seen drives with 10-25 pending and have them re-allocated and drive lives a happy long life until customer recycled machine and got new one.

Now, I serviced both consumer and business, so consumers don't always like to spend money or don't have money to spend, so it's all how you pitch it to them.

Now, if you replace it, and a month later the new drive says 10 pending (say for example you went HDD) what then? The customer is going to start questioning. At least that's what we experienced. Plus getting things RMA wasn't always pretty.

So we always gave customers a choice. Allow the drive to finish it's built in error correction, replace or maybe something else. Often it wasn't our prodding saying "it's broken" and "you have to replace it or your data will die" that got customers to replace, it was our comprehensive options, warranty and support no matter which way we went. That often triggered the "hey I get a new drive and warranty!" feeling and they went for a replacement.

Sometimes it was hard not to be jaded. Because certain systems came in that we knew would fail again, like the time my boss ordered a HP AMD motherboard (refurb) for a customer, had us install it then 4 months later it died. But that's a different story, point is, if you go full throttle being jaded, you can end up costing your customer more. My two cents.

The day of the HDD as the OS drive is done. Replace with an SSD whether problems exist or not.

ANY hard drive problem is an automatic replacement with me. HDDs are too cheap to mess with, it's faster to clone then the cost of my labor to work with it. ... the massive upgrade in speed is also worth the time there.

^^^ This.

ANY drive problem...especially if it's an old spinner drive...we clone to a new SSD.
Heck if it's an old spinner, the speed increase of an SSD shortens the time you spend working on a computer so if it's still a spinner...clone to SSD...enjoy much shorter time to work on the computer thus a smaller labor bill which will offset or at least partially offset the total price of your work. SSDs are cheap enough these days.

Always worth the attempt to clone. We pretty much hardly ever get a rig returning after cloning a failing drive. If the drive was that tanked to begin with the clone wouldn't complete.

Well, even though I will upgrade to SSD on request (or sometimes suggest it) it's not automatic.

If you just read here (and there are plenty of elsewheres) it's pretty obvious that SSDs have a "fail without any warning" rate that's far higher than HDDs do. And, note well, I didn't say "failure rate," because that's not what I'm talking about. They also make data recovery from an HDD look like a cake walk.

SSDs are not a panacea.

Sorry but 'pretty obvious' isn't really an argument. The "fail without warning" rate might be higher, but is it really 'far higher'? The HDD overall failure rate might well be higher than SSDs, so for some that is a major factor too. And as an OS drive you have massive performance gains which is the biggest attraction of SSDs. The possibility of sudden failure exists for all storage media, that's what I tell my customers. 1TB OneDrive included with Office 365 is a great way of reducing the risk of data loss because once set, the user doesn't need to actually do anything.

I don't supply computers without an SSD for the OS. If not you're doing your customers a disservice.

This is my worry about SSD. People buy them figuring because they don't have moving parts and are faster, there is a relationship with quality and longevity. But that couldn't be further from the truth.

The fragmented nature of SSD production, undocumented control chips etc., makes it a nightmare to recover data. Most customers that I dealt with with data recovery and SSD were actually shocked and had the impression that they were inherently better.

TLDR; in some cases magnetic media can have higher reliability and disaster recovery availability than chip based storage.

SSDs are inherently better, but that doesn't make them immune to the thousand natural shocks that flesh is heir to.

One day your client's SSD or HDD is going to fail, and on that day they'll have a choice of restoring from backup, paying for professional data recovery, or losing their data. As long as the first case is covered then you don't need to worry about the second two.

If you have a backup the SSD is always better. If you don't have a backup you should expect to lose your data either way.

And anyone here, everyone here, that deals with residential and small business clients on a routine basis knows that "having the first case covered" is, sadly, all too rare.

That matters. That matters a lot when it comes to catastrophic failure of storage media and the ability to recover from it at a reasonable cost afterward. When SSDs are at the same price point for data recovery, then you have a point about them always being better. Until then, that's your opinion, and you are free to hold it. Given what I've seen when un-backed-up SSDs suffer sudden death, I am absolutely not sold on the always better assertion. Not even close.

Speed is not the ne plus ultra for a lot of people. There are lots of other considerations, and the age of the HDD is far from over.

Let me use a car analogy. Everyone likes a good car analogy.

We sell a car that can travel at 100mph. We check that the car is in good mechanical order, that the seatbelts and airbags work, and that the customer knows how to drive it. We make sure that the customer knows that wearing a seatbelt is important. Then we send them on their way.

We don't fit a speed limiter to make sure that the car never goes above 30mph in case the customer later decides not to wear a seatbelt and gets into a crash.

I think we disagree on this last point.

Back to computers.

Yes, we all have clients who can't be bothered to back up their computers - but I'd be surprised if anyone has many clients who aren't aware that they should. As long as we've provided the correct advice and set up the correct systems then really that's all we can do. We're not responsible for our clients' behaviour, or their choices, and I think it's appropriate to let them behave like adults and experience the world accordingly. Some of those choices lead to unpleasant consequences but as one of my wisest clients once observed "I've lost all my data but no kittens were hurt", and nobody seems to go through a significant data loss more than once.

We routinely replace HDDs with SSDs, both as upgrades and as repairs, and we always make sure that there's a backup strategy in place - automatic cloud backup if possible, automatic backup to an external drive if not, manual backup to an external drive for really weird cases - but there's always a backup before they take the computer away. I consider anything less to be unprofessional, anything more to be mollycoddling.

I understand why you might prefer HDDs under some circumstances but those are the same circumstances under which you might need to make a shim out of a beer can (sorry - unannounced motorcycle analogy), and we try to avoid those circumstances. I'm not saying you're wrong, just that we're both right in different ways.

No, you and some others routinely replace HDDs with SSDs. Not everyone does.

Clearly, you are not alone in your approach and attitudes. And, clearly, neither am I.

And if you think that, "we always make sure that there's a back up strategy in place," after having said what you said before, then you're logically inconsistent. I can't, and don't set up backup protocols unless the client explicitly asks me to do so after I've explained how important it is. Some refuse.

And if there's something simple I can do to make a disaster less of one, well, I'll happily do it. And that means leaving HDDs in place on systems I'm convinced will not be backed up.

Routinely, yes. Recklessly, no.

And if you think that, "we always make sure that there's a back up strategy in place," after having said what you said before, then you're logically inconsistent.

Oh, it's always in place. I can't promise that the clients use it, but it's there.

Sometimes (very rarely) the strategy is "hope that nothing bad happens", but that's the client's choice, usually under special circumstances, and never our default option. We document those cases very carefully on the client's invoice, partly because nothing beats saying "I told you so" when you can prove that you did but also because seeing it in writing will sometimes convince people that you mean it. If I could get them to sign a DNAR for their computer at the same time, I would.

And that means leaving HDDs in place on systems I'm convinced will not be backed up.

If you decline to upgrade an HDD to an SSD because you don't think your client can handle it then I'd probably agree with you, though we don't have many of that kind of client. We're perfectly happy to refuse work that we don't believe is in the client's best interest (or in ours) and if that means that our client moves to another technician (or "technician") with different standards then so be it. On the other hand, if you replace a failed HDD with another HDD because you expect the new one to fail in the same way then you're doing your client a disservice by not insisting on a backup. You'll never find your client more responsive to the idea than just after a data loss or an expensive data recovery.

Oh, and you know that bit where I said "I'm not saying you're wrong"? That doesn't mean I don't sometimes think it.

(Edited for clarity and softening. Yes, I know it still rambles on a bit.)

I have had only had 2 users on 20 years willing to pay for data recovery.

There are lots of other considerations

Like not being affected by drops and vibrations in laptops as well.
