Hello.
I know that each HDD has a standard life and after it HDD maybe burn or fail, But how can I understand How much of the remainder of its life? Any program? Can "HDDlife Pro" help me?


Thank you.

The answer is: NO ONE

I guess some tools are exist that can show you the HDD health!!!!

Agree with you here, But WILL NEVER tell you when it`s gonna die/stop working.
like the Dr. Opinion will tell you how good/bad is ur health based on some tests, but never tells how much time you have left.

just backup your files and ur good :wink: my opinion

There are certain SMART attributes which estimate the remaining life based on the actual number of PE cycles as a percentage of the rated PE cycles.

I guess S.M.A.R.T is a option that I need. Can you show me a good tool for estimate it?

Smartctl is probably one of the better tools for SSDs.

If you think that watching SMART will give you any real indication of when a HDD or SSD is going to fail you are sadly mistaken. There are really only certain types of issues which cause failures which SMART can even detect in advance. The sad reality is that most HDDs and nearly all SSDs fail suddenly and with absolutely no warning.

Need to have a backup, you can't just rely on the health of a device.

"Lifetime" and "health" are two different things. An SSD's life is limited by its P/E cycle rating. That said, one would need to really thrash an SSD to rack up 3000 P/E cycles. It just wouldn't happen in normal use.

Quote:
ID # 177 Wear Leveling Count

This attribute represents the number of media program and erase operations (the number of times a block has been erased). This value is directly related to the lifetime of the SSD. The raw value of this attribute shows the total count of P/E Cycles.

I know HDD have a useful time and after it they can't working properly but why HDD manufacturers doesn't provide any useful information about their life in hours? For example, Write on HDD a text like "This HDD can working properly for 1 million hours".

Manufacturers provide an MTBF spec. It is intended to estimate the failure rate of drives in a large population, but is essentially useless for estimating the life of a single unit.

What is your idea about this photo? It show me my HDD life time. I can remember that many years ago this life time printed on HDD but nowadays it is not.

lets just entertain the idea this WAS possible(which it is not to any realistic time based estimation)

lets say HDDlife = x hours.

to find "x" you would need to enter into the equation:

- power supply quality as some kind of variable.
- reliability study of all components used in that particular drive (there are hundreds).
- climate conditions (how hot is it there, dusty, any static around, very cold, moisture etc etc)
- physical conditions.. (you have it in a stationary desktop or bang it around in an external case or laptop)
- Blind luck (some things just die wothout ever cause attribution)
- are there any unforseen firmware mistakes? you wont know until it is found or not found, and if found AFTER this lifetime estimation then bad luck)
- was the drive made perfectly well enough so the assumptions about lifetime are true? who knows, probably not

There are too many variables.

I challenge you to tell me exactly how long it takes to walk to the end of your street. Now do that exact thing 100,000 times to simulate a run of a number of hard drives.. same every time? one of these times you are going to get hit by an out of control watermelon falling from the back of a green chevrolet pickup driven by a chimpanzee because the dispatcher (firmware coder) wrote send(chimp) instead of send(chime)

it's also possible it will burn or fail inside it's warranty, let alone it's expected lifespan.

As Fzabkar notes, on an individual drive basis you can't g'tee anything with any reasonable level of accuracy.
You can get a general idea using statistic (largest sample size over longest time) but given that any particular models components can change many times over its production lifespan that too can only be regarded as best guess.

I'm sure there are more folks than just me still see drives from the WinXP era coming out of machines still working quite happily alongside cases of both mechanical and SSD's that have failed inside a year (or sometime even DOA )

with a view to what? saving your data or reselling as "usable" or ...?

In conclusion… back up your data!

So, there you have it: If you buy a hard drive today, there’s a 90% chance that it will survive for three years. If your drive makes it to the three-year point, you would be wise to back up your data, as there’s a 12% chance per year that your drive will die.
