Technical doubts hard disk 2.5"

[cloudff7]

If you eject the 2.5" HDD + case USB 3.0 in Windows 10 and then hit the HDD case with your hand, will it damage it and generate bad blocks? Did the shock move the HDD on the table?

Generally HDDs don't like shock, but they can take much more shock if there powered off than if its running.

 

Normal table vibrations probably won't hurt a hdd.

As far as I know, no. An HDD can handle some torture like drops from I'd say a meter high, just not magnets. They're more resilient than what people say. Just be as careful as people suggest you to.

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

 

In Windows 10 I ejected these 2.5" HDDs + Kesu 2530 or Orico 25pw1 cases USB3.0. When I removed the USB3.0 cable connector from the PC, my hand hit the HDD case and it moved on the table. I wondered if this impact is enough for needles and the mechanical arm to touch the magnetic disks and generate bad sectors and damage files.

Please do bot abuse HDDs. 
But cased hard drives can handle a little abuse while turned off. But if they are on and running absolutely do not hit it.

If it is the lovetap it seems to be, disk should be fine. Did you wait until it had finished spinning before unplugging?

I don't know if it was spinning, it's very quiet. I ejected it in Windows 10 for 3 seconds. I went to the USB3.0 connector on the cable on the PC and pulled the connector. It came out of the USB3.0 port and, by mistake, my hand hit the HDD case.

generally 2.5" spinning rust is designed for being in devices that move around (laptop, external hard drive enclosures, etc) and they have shock and vibration protection as part of their design..

 

but still, dont tempt fate, it's still a mechanical contraption and physics exist.. treat them carefully.

The answer is actually no it will not be damaged.

 

If you use the eject command properly, the HDD firmware will instruct the drive to finish pending tasks and park its heads properly. There is no possibility of a device level data integrity compromise or a head arm force retract.

Does ejecting a 2.5" HDD + USB 3.0 case in Windows 10 put the HDD in park mode? Some people said yes, and others said that ejecting only ends reading and writing processes but does not send a command for the HDD to enter park mode.

 

In my case, I ejected the HDD + case in Windows 10 and the LED on the USB 3.0 case remains on.

 

Some people reported that after ejecting an external HDD or 2.5" HDD + USB 3.0 case in Windows 10, the HDD remains on and operating.

 

 

Do 2.5" HDDs have any resistance or protection to prevent the heads and mechanical arm from touching the magnetic disks after contact or impact?

[Lurking]

HDD are designed to park the heads upon power loss. They generate the required power from the platters momentum turning the motor in a generator. I assume they sure do the same on a planned powering off.

 

It would be an awful design if they didn't park the heads under real life scenarios like ejecting or power loss.

I just ejected the 2.5" HDD + USB 3.0 case in Windows 10 but I read that ejecting has nothing to do with the HDD parking mode

It absolutely does as long as the USB SATA bridge is implemented correctly, either you read wrong or that person is writing wrong.

That is only true of really old HDDs as they are effectively dumb drives as all the control was passed to the drive from the controller card and you had to use an external program to park the heads if you wanted to move your PC because it didn't do it automatically.

 

Nowadays, that isn't the case as the heads are parked automatically when the drive is powered down which is exactly what happens when an external drive is ejected as it sends a command to the drive telling it to power down ergo the heads will also be parked and have NO contact with the platters (depending on how well the drive is manufactured, you can actually hear this action tasking place)

I have a 2.5" HDD + USB 3.0 enclosure case (Kesu 2530 or Orico 25pw1). I ejected it in Windows 10 but kept the USB 3.0 cable connected to the PC and the case. Then my hand hit the side of the case. Will this shock cause friction between the read/write heads and the platters, scratching them?
My 2.5" HDDs are 2013 models WD10JPVX-08JC3T5 and HGST HTS541010A99E662
