Two days ago, a colleague had a ancestral 6t mechanical hard drive broken。
It took him about 700 bucks to buy the hard drive, and it took him more than 3,000 bucks to send it back。
Four times the price difference is painful, but the video material in it is important and the failure to recover is even worse。
And the trick is, after asking a couple of hard drive fixes, it's a little cheap。
It is estimated that some of the bad guys have experienced hard drive maintenance and data recovery。
Some of them could get their next software done; others could cost hundreds of dollars to find a shopkeeper; others could cost thousands of dollars, like this colleague's brother。
So, is the data priceless, or is there a "smuggling" in the hard drive
Tony today, just talk about the mechanical hard drive. If you're done with patience, you might be able to raise your position
First, in order to find out what's in the "hard drive maintenance" doorway, we still need to learn about the "mechanical hard drive," a modern industry that makes the technocrats ecstatic
Mechanical hard drives, the most popular computer storage hardware in the present, have the advantage of being large in volume and cheap in price。
The system files in your computer c drive, the learning materials in your d, e, f drive, are stored in it. And it's called hard drive, by definition, because it really has a "disk."。
In short, the mechanical hard drive consists of "disc" and "magnetic head"。
The disks are used to store data, while the magnets are responsible for retrieving, reading and writing data, working formats and recorders。
But the mechanics of hard drives are much more sophisticated than record recorders, and they're all nanoscale。
Because magnetic heads are not actually exposed to disks while reading and writing, they are suspended on their surfaces, using electromagnetic exchange of data information. This distance is about 5 nanometers。
How small is the nano? About two dna chains of width, a thousandth of thick hair。
And the magnets will retrieve data through high-speed motion. For example, when we use mechanical hard drives, it can be understood that an aircraft is flying at a 1 millimetre pedal at every 25s orbiting the earth and covering every inch of the surface。
Harddisk manufacturers will seal the structure when it is produced (so that the dust does not affect reading and writing, leaving only one filter for air exchange). Then you connect the circuit board with the home algorithm chip, and a mechanical hard drive is basically alive。
A simple understanding of the mechanical hard drive, we'll know it's a very sophisticated thing。
At any point in time, there are issues that could lead to error in hard drive reporting, loss of data, etc。
So, the difficulty of data recovery, ranging from easy to hard --
* it's usually easy to fix the first one without paying, and we can understand that there's a problem with the "software level" of the hard drive。
Data are generally lost as a result of errors in partitioning, misformatization, deletion, cloning, loss of partition table information, etc。
It's not hard to restore the data, but the next diskgenius kind of hard drive fixes, which probably can get the data back。
As a result, the first scenario is less problematic, and the hard drive can continue to be used after repair。
The rationale is that when we delete documents, the data is not directly erased。
The data is still stored in the distribution table of the hard drive, but is marked as "empty" and is not shown anymore。
Unless the information is rewritten to cover the old information, the data recovery can be achieved by removing the "empty" tag。
This is why it is not recommended to continue copying documents in the event that hard disk data are lost。
♪ maybe it'll take a little money ♪
The second kind of malfunction is a little tricky。
Because it means that your disk surface is worn out or ageing, and the magnet is no longer readable. The usual performance is frequent i/o error-reporting tips, and slow-to-exceed hard drive reading。
At this point, remember not to continue to use it, and if you hear a sound from the hard drive, you must also cut off the hard drive immediately。
Otherwise, it is likely that there will be an increase in the level of the bad faith index, which will affect subsequent recovery。
In this case, unless it is the hardware boss, it is recommended that everyone return to the factory for maintenance or to a shopkeeper。
This step would require not only the preparation of a new hard drive, but also the use of specialized mirror software to mirror old disks to new disks。
It's hard to do without a certain pool of knowledge. But if you want to get back to the information, it'll be a few hundred dollars。
* this is going to cost a little bit, and if you want to restore the data, you'll have to be ready to bleed。
The hard drive, the water, the magnetic head damage, or the main plate doesn't work and the electric machine dies. Such maintenance has to be done and the technical requirements for maintenance staff are high。
And without opening, never knowing exactly what went wrong. Just like going to the hospital, the doctor always asks you to make a film。
That's what happened to our bad colleague's 6t hard drive。
So why do you have to pay more than twice the price of a hard drive when you open it? It is mainly expensive in these areas: dustless opening, professional labour costs, hard drive parts of the same type, etc。
These conditions are met by professional data recovery teams or companies, where fixed costs are set, and, naturally, higher fees. And much of the data recovery is time consuming. Half a month of hard drive is too common, and these labour costs have to be factored into expenditure。
Even so, it can't be said that 100 percent of the data is going to be successful. It's hard to imagine。
At that point, maybe the best friend would say:
It's a solid-state hard drive. It's small, it's reading speed-second-killing machine hard drive, it's anti-shock
That is correct, but the capacity of a solid hard drive is a price relative to the inch of the earth. A single one-t solid enough for a two-dollar two-t mechanical hard drive。
And the key point is that if the solid-state hard drive breaks down, there's little hope for recovery. Recovery is not only more difficult but also more expensive。
Thus, in the case of storage of information, mechanical hard drives are considered safer and more expensive。
Of course, the first game is a solid hard drive
In tony's view, however, recovery prices are generally high, mainly because it is a “low-frequency seller market”。
No one is willing to take over the market at reduced prices, even less if it is not the case that the price is not more expensive. The ultimate pricing depends on the difficulty of restoring the data and your connection to the boss。
Fortunately, the shopkeepers met with a formal professional and fair fee; but in the event of an individual “smuggling” you were anxious to lose the data, and could be killed at a price. After all, it's hard to get the data back, or the hard drive's broken。
Moreover, the priceless logic of data must be understood。
If it's just a few little movies, it's gone. However, the losses caused by the removal of important data are sometimes much more severe than thousands of pieces. This is also why data at the enterprise level are lost, often at prices of tens of thousands or even hundreds of thousands。
In sum, the recovery of data is not only expensive but also lucky. In order to spend less money, tony recommends that you be able to "back up in time." either it uploads important information to the cloud, or it's conditional to form its own raid。
While the cost of network services and the cost of buying hard drives is not cheap, the recovery of data is clearly much more cost-effective than the recovery of late data。
Of course, the mechanical hard drive market is now mixed, with the number of second-hand ores, stacks and stickers, many of whom have been buried. Sometimes the hard drive goes wrong, not because it was misused, but when it was bought as a piece of junk。
To find out how deep the water is and how to select a mechanical hard drive, the material might be enough for tony to do another two or three issues。
It is only fair to say that you have to look for a few more when you have to fix the hard drive。
