Question Doubts about HDDs ?

[cloudff7ps1]

Does the DVD burner drive have a magnet? If I store an HDD next to a 3 unit DVD drive, will the DVD drive's magnet generate badblocks and delete files from the HDD?

How many months can a notebook HDD remain unused without damaging its mechanics and data? to keep its mechanics healthy and the data turn on the HDD every day? do the manufacturers say something?

When transferring a new file to a notebook's HDD, is there a risk of corrupting files that are already saved on the HDD?


any type of small knock shock with the notebook HDD turned off generates bad blocks and damages?the beat I'm referring to is just a few centimeters long, for example. the HDD on the PC and the PC is located under the table so there is a space of centimeters between the PC and the wood. I lift the HDD and remove it from the top of the PC. This way it bumps into the wood and this will damage the HDD, generating badblocks even though it off?

NO, DVDs are written with a laser and can be read by an optical drive, not a magnetic one and is not magnetic itself at all.

Can be years. the technology is really good holding data, but after years can degrade.

Yes, could happen, that´s why important data has to be backed up redundantly on different physical drives.

A view cm will only have an impact, if the drive still spins and the head is not secured yet. While off (sleeping, spinned down), there shouldn´t be any defects. But over time can damage electronics parts inside the HDD.

To be safe, you should always be aware that any storage device can get defective every time

Update your post to include full laptop specs and OS information.

Also include specs (make, model, capacity, how full) for all connected DVD's and HDD's along with how they are connected.

I would not expect any magnetic fields originating within an optical drive (CD,DVD) being able to adversly affect data on nearby HDD's.

As for HDD's bumps etc. causing damage and/or data loss that depends on the seriousness of the "bump" itself and the quality of the HDD. Some are more rugged than others.

Presumably, the motor in an optical drive has a magnet in it.
But that is sooooo tiny in comparison to the actual magnet that is inside an HDD, it is totally irrelevant.

Today, you are much better off using a SSD in a laptop.
It will be more reliable with no moving parts, and the performance difference is noticeable.

All of that is irrelevant.

This is specifically what backups are for.

Is the mechanical part of the notebook HDD lubricated? If the HDD has not been used for years, the lubrication dries out and the engine and mechanics lock up, making the HDD unusable?

I have the HDDs Apple HDD HTS541010A9E662 current firmware JA0AB5D0 and WDC WD10JPVX-08JC3T5 firmware: 05.01A05
On the WDC HDD, software like Victoria and GSmart control has difficulty detecting the Smart, unknown appears but sometimes Victoria can detect it and shows Good health, Crystaldiskinfo always detects the smart of this HDD. I thought about updating the firmware but is it complex?

yes the DVD drives have magnets inside it at the top to lift the disc I have 3 drives stored in the same place and I thought about storing HHDs next to the drives but I thought the HDD has problems with magnets generating badblocks and deleting files

Yes.

Possibly.

No, putting an HDD on a shelf, on top of a DVD drive, will not cause any data loss due to the DVD drive motor.

Is there any difference in generating badblocks and errors between friction and knocking with the notebook HDD turned off or the HDD turned on? in my case the small knocks with it turned off

What is the mechanical construction of a notebook HDD? Does it have lubricant in the platter motor and in the reading heads? If you don't turn on this HDD for years, the lubricant dries out and the mechanics locks up forever, making the HDD unusable?

If I buy a used HDD and its SMart test results in Good, is there a risk that this HDD has been manipulated by someone to Smart and firmware hide badblocks and errors? Don't show secretly hidden badblocks and errors

What type of memory is used to store the Smart and the HDD firmware? Does this memory need to be energized constantly to avoid losing firmware and smart data?

Is there any problem with storing HDD inside furniture drawers and HDD on top of HDD?

When a drive is "not in use" it can withstand greater "knocks" than when it is in use.
But still, handle it as little as possible.

If you don't turn on this HDD for years, the lubricant dries out and the mechanics locks up forever, making the HDD unusable?

Yes, that is a possibility. And please don't ask about "how often".

If I buy a used HDD and its SMart test results in Good, is there a risk that this HDD has been manipulated by someone to Smart and firmware hide badblocks and errors? Don't show secretly hidden badblocks and errors

Unlikely. Changing the SMART data is a manufacturer function. Not some dude selling a used drive.
BUT....any drive can die at any moment. New, used, never used, whatever.

Is there any problem with storing HDD inside furniture drawers and HDD on top of HDD?

As long as it is not knocked around, no problem.

Any drive is liable to die within the next 0.25 sec.
Or, it may last for 2 decades.

 

[cloudff7ps1]

my tests opinions? two HDDs is good or bad for some storage files?

 

[cloudff7ps1]

If I store HDD next to 3 sata dvd drives and the 3 drives have magnets will these magnets generate badblocks and delete files from the HDD?

 

[TerryLaze]

For a magnet to be strong enough to harm your hdd it would have to be the size of the whole PC, a whole full tower PC.
