First, consider the logic faulty. Flash card in this case will be recognized by the system as blank or not formatted. The recorded files will not be visible. Such a failure is the result of premature extraction of the card from the connector. Also, the cause may be a sudden power outage of the operating system. In the end, all documents will be in place, and the service table file system is corrupted. Thus, you will not be able to see the data stored on the media.
To solve the problem, there are special data recovery programs. It is best to use EasyRecovery. However, the program may not always help solve problems. Sometimes, to recover important files on the flash drive, you must perform laborious "jewelry" work.
To this kind of problem with the flash drive not occurred, it is necessary to use the "safely remove hardware" to complete the work with the media. Also do not need to pull the carrier out of the computer until the system considers the data from it.
Special attention should be paid to mechanical breakdowns. After an injury the carrier may temporarily operate with virtually no failures. Failure of this kind occurs from careless attitude to the device. First and foremost is the damage to the body of the flash drive, then shifted to the separators, contacts, and lands the catch of the ban and write permissions. If cracked chip memory, the data in any case will be lost. In other cases, the need to recover the contacts, to carry out the replacement of damaged parts, to strengthen the USB connector, to repair or replace the housing.
To avoid this problem, you must initially purchase a quality USB Flash, which are durable and not too slim. It is best to buy media in a one piece body. Popular flash drive with rubberized casing.
Advice 2: How to repair memory card
Statistics says that the main reason for the failure of most of the cards memory is faulty logic. It is not excluded that the cause of the damage can be mechanical damage, thermal or electrical effects. Sometimes there is a deterioration of memory, but this is quite rare. How to fix card memory?
Repair the logical failure. To recognize them is easy. In the case of the causes of failure map of the memory detected by the computer, but is perceived as empty or unformatted. The files that were on it were recorded during the last session will not be visible. The reason for this may serve as premature removal of the device from the connector or the power turns off suddenly. As a result, all documents are as before, but recognizing them is not possible because of damage to the file system table. Use special data recovery software. This operation can help repair card memory, but not in all cases.
Be careful removing the card memory from the contact happened only after the appropriate signal from your personal computer. Use the option safely remove the device. This will avoid the most common causes of damage to the card memory.
Protect the card memory from mechanical damage. For this you need to purchase a quality carrier, placed in a tight enclosure capable of withstanding mechanical impact medium degree. In this respect suitable card memory in rubberized and monolithic buildings. Failure does not always occur immediately after a mechanical impact. The map memory can also operate for quite a long time, so pay attention to all the visible changes. Prevention of problems is much better than its immediate elimination. To fix map memory, you'll likely have to turn to the experts. And it will take some time, which would you most likely be able to spend more usefully, having information stored on your media.
