Question Sentinel suddenly warn me about bad HDD Health? Should i be worried?

[jcchimaera]

Spoiler: SENTINEL

I mean why the performance still at 100% then?

For months everything was 100% and then 2 days ago suddenly the health drop down to 17%

I'm just using this external HDD for storing ISO's files.

But when i re-checked with WD Dashboard the health still showing at Green (Normal)

Spoiler: WD DASHBOARD

I'm Confused. 😵

Can you verify the poor health with another application such as Crystal Disk Info?

You don't need to worry at all if you don't care about the contents of the drive.

Continued health decline will eventually affect performance. When is speculation.

Drives can and do fail with very little warning.

Here it is sir.

Poor health confirmed.

Caution on the reallocated sectors count is not what you want to see.

Frequently, that number will increase significantly rather quickly.

I'd replace it immediately.

It could last days, weeks, months, or years.

But if the stuff on it is of little or no value to you, maybe do nothing. Your choice as you are the only one who knows how valuable that stuff is.

Relocated Sector Count means that there were some bad sectors and data is relocated to spare space on disk, When bad sectors occur likelihood of new ones is greatly increased and once spare space is over reached your data is in peril.

Alright, i got the gist of it... thank you guys. 🙏

Here it is sir.

I'm curious... do you power your PC down daily? I'm asking because your drive has a power on count of 1691 with a power on hours of 7464... out of curiosity I just downloaded and ran the same program to look at my 4 year old Seagate Barracuda Pro 12TB drive... and it's quite a difference.

Of course... my PC is on 24/7 but basically what I am seeing here is 5x less power on counts with 5x more power on hours.

There was a discussion the other day about whether or not leaving your PC on 24/7 was helpful/harmful to hardware... and I must say this is an interesting observation.

That depends on Power saving plan in OS. There is a setting for idle time after which it goes to "sleep". If set to 0 it will never do that, when time is set it will still wake up when accessed. That can drive start count higher. Some drives may have that set in it's firmware too. Usually the "green" ones.

Ahhh ok, yeah that makes sense. For whatever reason the difference just jumped out at me... I was like WOW! Haha... and yeah, I don't turn mine off. It gets rebooted periodically but other than that it stays on... under the high performance/ultimate performance power plan.

Mine is External HDD sir... i taken it out from broken laptop and just slap enclosure on top of it.

So maybe that's the reason why it got a lot of start-stop count.

I mean it's still even lower count compared to me other HDD...

I know it's external... doesn't change the count any. Massive 5x difference in yours and mine... and mine is in "good" health.

Maybe it was your power settings.

Dunno about that... it's already around 1500-ish when i got this HDD from my friend broken laptop. 🤔

Well... let's call it "Different Circumstances"

Your drive IS failing. 220 bad sectors is well past the point of unsalvageable. I'd be stunned if they aren't spreading. Any data in the surrounding sectors is at high risk. I would backup anything of value and retire the drive. It's only going to get worse.

The reason WD Dashboard isn't reporting an issue is because SMART hasn't tripped. It's VERY hard to trip SMART. I've only seen SMART trip in the most extreme cases, after significant data loss has already occurred. You could run a Long Self-Test. There's a good chance the drive will fail it, but even if it doesn't, that doesn't change the fact that the drive is damaged.

Yeah... i already ordered brand new 2TB WD Elements because of this bad news.
