What is a hard disk crash?

crash the hard disk means, if the hard disk suddenly stops working or makes strange noises.
The cause of a crash is mostly on the hardware of the hard disk.
(The hardware is the part of the hard disk, which can be touched)

Possible causes are: overheating of the hard disk, age of the hard disk,
How do I know that my hard drive has a crash?

My computer displays an error message when saving or reading data.
The computer wants to make a diskchek at the start although the computer has turned off properly.
Short but loud noises, scratches during the computer while the computer wants to access the broken hard drive.
How can I prevent a hard disk crash?

Carefully handle the hard drive, do not allow it to fall down, do not allow the computer to overheat, make regular back ups, do not load programs that are not needed or are not safe.
What to do in a crash?

If the computer is not working properly, then turn it off.
If the computer still works, then all programs terminate, possibly make copies of the data, which are still needed but in no case overwrite backups.
For cool air, the computer might be overheated.
Make the list of files on the hard drive, which are most important.

Remove the hard disk only when the computer is switched off!
IMPORTANT! Do not even try to do something if you do not know how, the less you do yourself, the greater the possibility that an expert can save the data!

What is a “headcrash”?

A headcrash is the direct contact of the surface of a magnetic disk of the hard disk by one or more read / write heads, which leads to a mechanical damage to the storage layer and contamination of the disk. This makes the data loss possible.

 

Causes of a headcrash?

Wear, fat plate incorrectly installed, strong temperature fluctuation, vibration eg. By impact, operation at too high a height, power failures or contamination.

 

What to do in a headcrash?

Do not use hard disk, which is important data which still need to be saved to make a backup.
Data recovery in case of a crash of the hard disk

Since it is a mechanical damage, a dispenser plate is required (a dispenser plate is a hard disk which is exactly identical to the broken hard disk with respect to the model, firmware, serial number and date code). The damaged parts of the hard disk are replaced by new parts of the dispenser plate. Thereafter, the sectors are cloned,
the file system is reconstructed again and the data restored.
