Why does not the tablet see the USB flash drive?

Blinded by the popularity of trendy device - the tablet - does not see the flash drive. What could be the reason, and what actions to take to help your device "see through"? The most common misunderstandings we will touch on within the framework of this article.

What's wrong?

Before blaming the manufacturer for incompetence, you should carefully understand the very essence of the question: "Why does not the tablet see the USB flash drive?" After all, sometimes the consumer is incapable of understanding the actions required of him, which ultimately affects both the functionality of the gadget and the efficiency of the operation of the electronic machine. Agree, not every user possesses extensive knowledge in the field of computer hardware. But the tablet is a miniature computer, in which the possibility of connecting peripherals, as well as external memory drives, in particular Flash-carriers of various types, is realized.

Invisible format

If they talk to you in a foreign language, which for you is a mystery with seven seals, will you understand the interlocutor? Hardly! This misunderstanding is inherent in the situation when the tablet does not see a flash drive having an undetectable file format, that is not known to the gadget system. It is enough to format the flash drive in FAT32-standard using a computer, so that your device recognizes the expected "guest". It is the above-mentioned file system (File Allocation Table) that allows portable devices to work correctly with a variety of flash media. However, let's talk about everything in order ...

If the tablet does not see a microsd flash drive:

1. Ensure the physical integrity of the memory card. Visual inspection for mechanical damage such as chipping, deformation or deep scratches can convince you of the inexpediency of using a deliberately faulty information "custodian".

2. If an adapter (adapter) is used, pay attention to the contacts: they must be clean, free from oxidation and fat.

3. Sometimes the tablet does not see the flash drive due to the fault of the card reader - a special device that facilitates synchronization of various formats and types of Flash-cards. Check if he perceives a "familiar" memory before. If the result is negative, you will need to reinstall the device driver.

4. The connecting cord can also be the culprit for "misunderstanding." Again, verification is required, both for the physical and technical integrity of the cable, and for the software correspondence of the established data to work with the device through the connecting element.

5. You need to make sure that the Flash you bought does not belong to the micro SDHC or SDXC standard. This is an extremely important point, since the volume of such drives is often incompatible with the hardware capabilities of the device, especially if you take into account that your device does not belong to the category of prestigious. Usually the type of micro CD cards is limited to 8 GB. Most budget tablets are designed for eight additional memory.

Important! A huge role is played by operating conditions: the metro (crush), public wheeled transport (inertial risk of damage), an open bus stop (rain, damp, heat, dust) - all these factors are predetermining in the situation "the tablet stopped seeing the flash drive."

Universal Usability

USB connectors today are equipped with almost all electronics. A portable device is not an exception to the rules. An incredibly popular and universally applicable serial interface, plus a Flash drive, has become an integral part of the user world of high-tech digital devices. At the same time, the comfort and efficiency of using such an information carrier can sometimes be a serious embarrassment for those whose devices do not support "heavy" volumes. Therefore, it often happens that the tablet does not see a usb flash drive of a critically unacceptable size. And still, in case you are sure that the connected Flash-memory meets all technical and system requirements, and the fact of the presence (detection) of the drive by the gadget remains for you a "mystery", pay attention to several important points:

• In the autonomous power mode , most tablets give insufficient voltage to the USB bus; It is connected, first of all, with the implemented by the developers, so to speak, an economical scheme of energy consumption.
• Some gadgets do not provide or disable the system notification function for an embedded device that extends memory properties. In this case, it is advisable to install the file manager, or activate the detection option in the device settings.
• Often the tablet does not see the USB flash drive just because the OTG cable used during the connection is too long or mechanically damaged.

Finally

In the case when all the methods have been unsuccessfully tried, and the confidence in the readability of Flash-media is confirmed by undeniable evidence, your "blinded" gadget requires professional repair.
