SPOILER ALERT!

After the really hard disk or mobile difficult disk is broken, how can ordinary customers from a non-professional point of view, immediately after passing a specific test, also confirm no matter whether it is actually necessary to open the tough disk and

This short article will clarify in detail and teach you the way to do the test. According to the test final results, it really is analyzed no matter whether it truly is truly necessary to alter the head or motor by opening the disk to recover the information on the really hard disk.
Certainly, essentially the most precise test is always to use an expert hard disk information recovery tool to test. Folks certainly do not have this condition. At this time, you are able to use some totally free software and judgments downloaded on the web to test. Although dv images 's not probably the most correct, but You'll be able to also remain ten or nine.
Beneath what situations does a mobile challenging drive in addition to a desktop difficult drive need to be opened for information recovery purposes? When the challenging disk head is broken or the motor is locked, what's the common efficiency of your hard disk head damage?

The broken head is bumpy

The intact head is smooth and bright
1. If the difficult disk emits 'squeak', 'kaka sound', 'kacha, kacha' or 'very quiet hum' when the hard disk is powered on, from time to time the hard disk must be turned on ahead of power on Paste it on your ears and listen to the sound with electrical energy.
two. Right after the really hard disk is powered on, place the challenging disk or mobile really hard disk within the hand and find that it'll not move following shaking for any even though, or there's no response. In these two circumstances, the difficult disk motor might be locked and trigger no functionality on the touch , See the picture beneath for the difficult disk spindle motor.

3. Following the difficult disk is powered on, the motor rotates, however the head of your hard disk doesn't emit a seek sound (a little related to Dada, Dada, and Dada). In this case, it truly is most likely that the head is stuck around the head rack of the hard disk. There is certainly also a serious deformation from the magnetic head just after the magnetic head is stuck within the parking position.

four. The really hard disk can scan the whole disk (such as DiskGenius tool) by means of the scanning computer software, and then look at the bad track scanning situation. If it is a normal poor track, among the heads within the head assembly is broken, but not all heads are Bad, that is, negative tracks seem at intervals or when scanning undesirable tracks, and so long as terrible tracks are skipped, the head is generally damaged.


Since the current difficult drives are fundamentally far more than two heads, that is certainly to say, there is a head on the prime and bottom of a layer of discs. It is possible to appear in the figure under.

The common point is the fact that this disk is often a lap or a handful of laps when reading and writing huge files. In the event the small file could be a specific head, it is actually adequate to run one particular lap. Then it is also precisely the same when testing. If it's A disk with 4 heads (respectively 0.1.two.three), head 0 is no challenge, head 1 is terrible, so it ca n’t be read each time the head 1 is broken, so it will show additional regularity when testing undesirable tracks Terrible way.

So soon after determining that the marketplace must be opened, can the data be successfully recovered? It can be not that the hard disk is replaced using a very good head or motor following the disk is opened, and also the data on this challenging disk may be restored. There is also a problem of probability, primarily determined by several crucial variables.
1. The degree of damage towards the disk of your difficult disk. When the hard disk is broken seriously, sometimes there are scratches that could be recognized by the naked eye. Generally this disk has no chance of recovery, but if the scratches only seem on a single layer in the disk, then There is nevertheless a certain likelihood to read the significant data from the couple of scratched discs.

two. When the firmware region is also damaged, and it is actually particularly critical, then the data area is useless, because the firmware area may be the microcode reserved by the manufacturer when the tough disk is shipped in the factory. dv images is usually to tell the buyer information region of ​​the hard disk firmware location. Some significant data for example the beginning position, the flying height of the magnetic head, the position in the marked bad track, the total size with the really hard disk, etc.
3. In recovery file video of your disk generated soon after scratching the challenging disk contaminates the cavity from the really hard disk, there is absolutely no need to replace the magnetic head, plus the information can't be recovered completely.
