Question HDD 2.5" internal construction and shock protection ?

[cloudff7ps1]

Do 2.5" HDDs have any protection against impact or accidental shock hdd 2.5" in power on operates to prevent the needle and mechanical arm from touching the magnetic disks?

Do 2.5" HDDs manufactured in 2012/2013 have this protection or only the most recent ones?

Does shock to the 2.5" HDD case when moving it on the table make a big difference to the HDD falling from the table to the floor?

Make and model HDDs?

Are you referencing "head parking"?

Shock is a matter of G-forces" acceleration/de-acceleration.

Strength and direction matters with respect to the internal components.

Overall if an HDD was "kicked" hard enough across the table the end result would likely be the same as if the HDD dropped from the table.

A car hitting a telephone pole at 60 mph would likely have the same shock as if the car nose rolled off of some parking garage level and hit the ground at 60 mph.

There are variable: a car hitting a telephone pole head on at 60 mph may crumple. If the car hits the telephone pole while sliding sideways at 60 mph then the car may be cut in half.....


As a starting point:

Generally the "real world" damage or consequences of dropped or hit HDD's are due to losing data on the drive.

Hence the need for having multiple, proven recoverable backups.

Just my thoughts on the matter.

In your previous thread regarding external drives, you were informed about the shock protection, in G's, of various drives.

Even though this is for an 'internal' drive, how is this markedly different?

My 2.5" HDDs are a bit old, from 2013, models Western Digital WD10JPVX-08JC3T5 and HGST HTS541010A99E662. I couldn’t find their datasheets. i have other new hdd 2.5" seagate ST500LM030

Automagic head parking has been a thing for every hard drive sold this century.

If you are worried about dropping a laptop with a HDD, consider using a ssd instead.
Performance as a C drive will improve your desktop quickness greatly.

After dropping a laptop, broken hdd will be the least of issues.
Probably will have a broken screen also.

I asked Microsoft and they said that Eject in Windows 10 does not put the 2.5" HDD + USB 3.0 case in parking mode, ejecting only ends read/write operations

The drive does that on its own.

Going back to ALL your previous questions....what is the risk you think you face?

 

[cloudff7ps1]

After ejection I wonder if the HDD will not perform the parking command because ejecting does not turn off the 2.5" HDD + USB 3.0 case only ends reading and writing but the case remains powered and operating

I asked Microsoft

Microsoft does not make HDDs. Windows sends an ATA sleep command to the drive on eject, and what the drive does with that + how quickly is up to the HDD manufacturer. Complicating matters is the USB enclosure, which may not pass through such a command properly or in a timely fashion.

This is why you must test these things yourself, instead of asking companies about another companies' product, which is clearly a waste of time. Why would they guarantee a 3rd party drive in a 4th party enclosure always behaves in a certain way? It is also a waste of everyone's time to ask the same question over and over again until you get the answer you want, because even if you do---how can you trust that person's opinion? They don't make the OS or the HDD or the enclosure, or even have them all.

If it's preponderance of opinions you value most, well the majority vote can be wrong too and is not consensus. But given that you usually post the same question all over the internet, you could set up a poll on some forums. Not here though--that's been disabled here for non-admins for at least 8 years.

Is this ATA command responsible for the 2.5" HDD + USB 3.0 case entering parking mode?

My cases are Kesu 2530 and Orico 25PW1
The HDDs are WD10JPVX-08JC3T5 and HGST HTS541010A99E662. and 2.5" Seagate ST500LM030
What is the average number of seconds for the HDD to enter parking mode after ejection in Windows 10?

Probably 1 or less.

I have a drive on the desk next to me.
500GB Seagate.P/N: 805217-021
2.5" format.
Removed from an office laptop.

Manufactured - 18 Oct 2016
First stood up in the office, mid-2017.
Said laptop was moved between work and home dozens of times. Laptop bag or backpack.
Last powered up in that laptop, early 2021.
Removed from the laptop, early 2021.
Tossed in a desk drawer.
Moved between various desk drawers, maybe a dozen times over the years.
Dropped in a shopping bag, to survive a 10 mile drive home.
Plugged in to a toaster style dock...hey look...it still works.

I can go for a potentially greater destruction level if you want.
