If you have even the most distantly related to IT, you can not be unaware of the fact that in recent years the most common storage media are the usual memory cards.Prices per gigabyte (yes, megabytes of no one remembers) keeps crashing and reliability remain at the same level.
Today is no surprise situation where a flash drive for 4-8 GB can simply donate with information whose aggregate amount does not exceed a couple of megabytes.Earlier on this one I could not even think!
But this cheapness has its downside.We do not casually mentioned that "the reliability of the damage remained the same."Moreover, the reliability of this is directly proportional to the size of the flash drive.For example, if a memory card of 2 GB of "natural conditions" is almost impossible to re-record as many times that it is out of order, from the card to 64GB such trouble can happen easily.
particularly sad that even the brand-new flash so naturally break down as if they were used for a few years!Often, they carry with them a bunch of data ...
Why is this
you noticed how big the flash drive had been before, and what they have now?Today there is a memory card the size of a fingernail, which is placed as much as 32 GB of data.Unfortunately, the physics can not be fooled.
for huge data density have to pay.Thus, for error correction (which in this case will necessarily) correspond to complex mathematical algorithms.Because the same data density the number of its cycles greatly reduced.In short, all in the spirit of the modern economy: to release something, having seemingly attractive features, but forget to tell what it is fraught.
But enough of the lyrics.Suppose that you can not read the flash drive.What to do and how to proceed?To answer this question we must deal with theoretical issues.
What are the problems with memory cards are the most common?
Outset that all our solutions are valid for Microsoft Windows, as these operating systems are the most common.Note that the regular use of the flash drive and work with important files you need to constantly make backups of important information.
In this case, even if the flash drive is opened as a label, at least you do not lose important files irretrievably.
Most often the problems start when the user pulls out the flash drive without completing preliminary work with it (the function "Stop the unit").In this case, often suffers from overhead, resulting in a determined drive stops and read.
What should I do first?
There are many reasons because of which does not open the flash drive.What to do first?Make sure that you are not connected to any network drive.On Windows it happens often that the system assigns to the flash drive with the same letter as a network drive.In addition, if a memory card is formatted with a file system NTFS, you sometimes have to assign your own letter.
Notebooks
Most often these problems occur with laptops, especially the older ones.Look, you are not busy other ports if each of them sticking out of the splitter, which you plug in USB-lamp, fan and something else, then with high probability we can assume that the motherboard simply can not cope with the load.
Unplug unnecessary devices, and then try to re-insert the memory card unfortunate.
If even then you can not open it, connect it to another computer.And it is impossible to open it?Then, almost certainly a problem in the drive.Important!If you do not have a second computer to test it on a memory card, do not forget about the simple fact that he USB-connector could well fail.
Whatever it was, but today it is very difficult to find a car equipped with only one such connector.Try to connect the memory card are all available.Maybe even one of them read it properly.
Computers
Attention!If it is an ordinary computer with a front USB-connector, remember their most unpleasant habit for any reason fail.It is for this reason it is often not open flash card.What should I do in this case?Go to the store and buy a PCI-card with a whole bunch of new USB.
Again attention!Note that the power of the old power supply and features old motherboard (if you have a computer) may not corny enough to power such devices.So pre-verify its specifications with the purchase.
Card Readers
If you are wondering, why not open the flash drive does not hurt to find out is another question.Until now we have spoken only of their USB-species completely lost sight of the existence of Micro SD and other memory cards.
so.Card reader to work with them very often far from perfect.Many collectors of sin that even in expensive computers set very questionable Chinese handicrafts that are literally falling apart after a couple of months.
author himself I watched a brand new flash drive is defined, but not open.And this is connected it was just the same with the poor quality of the equipment.If possible, try plugging a memory card from another computer.
Note also the adapter.The fact that the Micro SD connected to the computer only through it.When a Chinese consumer goods are often caught faulty adapters.Just replace it and in most cases, all your problems will be solved.
What other cases?
Please click on the "Start" button, and then seek out the point "Control Panel".Left-click on the item "Administration", double-click the "Computer Management".
dialog box, in the right part of which should be to click on the "storage device."If you see a flash drive in the list that appears, and its volume was determined correctly, the whole point of the file system fails.
If the disc do not have any valuable files, it can simply be formatted using the regular system tools.In the case where it is impossible to do this, you can use the proprietary utilities for their forced formatting.
With many problems copes program HS2.0_Utility_Repair_2 (suitable for virtually all storage devices), or something with a difficult name CBM2090UMPTOOL.However, the latter program is remarkably bad flash formats of Chinese production, so neglected it should not be using.If you can not read the flash drive (to do that in typical situations, we have already discussed), it is best to look at the card closely.
little tricks on existing
Keep in mind that the official website of all self-respecting manufacturer of memory cards have special tools to force formatting.If you do not open the flash drive on the computer, use their help.In
when incorrectly determined the amount of disk, everything is much more serious.Rather, the point of failure of its controller or in a serious damage of the internal structure.
If the flash drive is manufactured by unknown Chinese experts, it is a risk that you have bought the old model, the true capacity of which is equal to 521 MB!Cunning Chinese simply re-stitch the controller, and then sell flash gullible buyers.
If you have such a flash drive (not open, asking format), then think about restoring it useless.It is better to buy a new one, and not to spoil their nerves.
