Full review of the new 7-inch tablet
The reasons for the appearance of an error with recognizing a flash drive by a tablet are different.
There are a number of reasons why a flash drive remains invisible to your gadget. This article is intended as a quick introduction to the most common problems.
- Possible reasons why the tablet does not see the USB drive;
- Problems with microSD drives;
- Blitz tips.
Possible reasons why the tablet does not see the USB drive
A convenient and compact USB flash drive has long become the most popular mobile storage of information. Naturally, we have the right to require our tablet to work correctly with external flash drives.
But if you have suffered an evil fate and your tablet refuses to see the USB flash drive, pay attention to a number of possible reasons:
- Majority tablet computers and smartphones are only equipped with a microUSB connector and do not have a standard-sized USB connector. In such cases, a standard USB flash drive is connected through additional fittings. This, in turn, adds to the number of places where contact can be unreliable. If the device was previously working properly, then probable cause failure may be the lack of contact at the joints.
A thorough external examination may, for example, reveal that the tablet does not see the flash drive through the OTG cable. The manufacturer saved on materials - as a result, external damage “chopped off” your flash drive. The vast majority of adapters, USB cords and OTG cables are made non-separable, which means that they cannot be repaired. If any malfunctions are found in the above devices, it is recommended to replace them.
- For different types external drives an electrical supply of 40 to 300 mA is required. The flash drive is powered via a USB connector (there are two extreme contacts on the connecting plate). By virtue of design features it happens that the tablet is not able to provide the necessary current for the operation of the drive.
There is only one way out of the situation - this is an adapter with a separate power source. To be honest, such a thing is a very impractical thing and makes sense only in exceptional cases. The most practical will be to choose a flash drive that will match the parameters of your device.
- The most common cause for concern may be the situation when the drive is attached, and there is no notification pop-up on the tablet. The natural conclusion is that the tablet does not see the flash drive.
Look into the Device Manager, if it displays a flash drive, then the problem of the lack of a pop-up window must be looked for in the tablet settings.
Problems with microSD drives
The microSD drive is designed in such a way that, from the point of view of mechanics, there is, in principle, nothing to break there. If the inspection did not reveal cracks and impact marks on the body, then most likely the reason is different.
- Perhaps the tablet stopped seeing the memory card through oxidation or contamination of the connecting contacts. A cotton swab dipped in ethyl alcohol will help clean the contacts.
- Another reason why the tablet does not see the microSD flash drive is the use of a card reader. To synchronize the operation of the tablet and a card reader that has its own software, you may need to install a driver.
- Recently, microSDHC and SDXC cards have become especially popular. These flash drives are characterized by a huge amount of memory and high data transfer speed. Only gadgets of the latest generations are adapted to work correctly with them. It is possible that the tablet does not see the SD memory card due to incompatibility.
- Different operating systems use individual markup file system. For example, if your Android tablet computer has stopped seeing the memory card, the problem may be formatting incompatibility. Most devices on Android software do not recognize files with the NTFS markup system; FAT32 file system markup is acceptable for them.
There are two ways to deal with this problem:
- Reformat the flash drive to the required standard.
- If the tablet does not see the memory card through a discrepancy in formatting, then one of the many programs that will “teach” your gadget to recognize different formats will help it to see clearly.
All sorts of problems with the electronics around us happen all the time. The first golden rule in such situations is not to panic. We must calmly try to deal with all aspects of the problem.
If the tablet does not see the memory card, what to do first:
- Start by rebooting the device (an action that will rule out a simple system crash).
- You need to check the flash drive on another device (this will confirm whether the drive is working or not).
- If it is possible to connect another USB drive to the tablet computer (this will determine whether your device is generally capable of connecting via a USB port).
- When purchasing flash drives, monitor device compatibility. Ideally, when buying with you, have a tablet and check it without leaving the checkout, so to speak.
- Do not exclude damage to wires and contacts. Intensive loads on the connectors are the cause of most malfunctions.
Friends, today we will look at the process of how to connect a USB flash drive to a tablet. But first, it’s worth figuring out what types of devices specifically can be connected in this way, what inputs can be used, and other important issues. This will help avoid misunderstandings and additional questions later in the discussion. Therefore, it is recommended that you familiarize yourself with this information too.
In general, it all depends on which tablet you are holding in front of you: it can be an Android device or a Windows device. And if with the latter in most cases everything is simple (later you will find out why), then with the first two there are many controversial points. This is especially true for the offspring of the Cupertino team, due to the protection operating system"apple" gadget. Each of the devices has its own special inputs, with the help of which, in principle, other devices and various devices are connected for further work. Neither the iPad nor any Android tablet has a USB input by default, through which flash drives are connected. What to do?
So, is it possible to connect a USB flash drive to a tablet? Definitely you can! Simply, as mentioned above, each type of device will have its own connection method. Therefore, which is on your tablet, and then look possible ways and options. You can choose any of them and apply the one you like in practice. Go!
iOS
- by the most in a simple way is to purchase a special device, one output of which has a Lightning connector, and the other has a USB output for connecting to a computer. It turns out that this is a simple flash drive that can be connected to an iPad or iPhone to view any available information on it. Such gadgets include, for example, Leef iBridge and JetDrive Go devices. Their cost, of course, is not very pleasant, but if necessary, you can buy. The essence of their work is as follows: you connect a flash drive to a computer, download the necessary files (for example, movies), then insert it into your Apple tablet and view the data through an application from the flash drive manufacturer. It is worth noting that if necessary, you can transfer or copy files from Leef iBridge and JetDrive Go directly to the iPad.
- The second option: connect the USB flash drive to the tablet through an adapter. You can purchase special Lightning cable to USB Camera Adapter, which by default supports streaming photos and videos from a USB drive to a tablet. If you have a jailbreak, then with the help of a special iFile tweak, you can bypass this limitation and drop absolutely any documents and files directly to your gadget. Please note that without hacking the operating system, you will be able to use the video format supported by the product from Apple.
- Using the same cable mentioned above, you can very easily connect a USB keyboard to your iPad. When you connect a device, a notification will pop up on the tablet screen stating that this accessory is not supported by the system. But if you press OK, then the keyboard will function just fine.
This is how the Lightning to USB Camera Adapter cable looks like, which will allow you to connect a regular USB flash drive to your gadget Android
- Compared to the previous type of device, it will be somewhat easier for you. It is enough to purchase, which will allow you to connect a USB flash drive to an android tablet. This connection is possible if your tablet is equipped with a microUSB input (the place where you insert Charger). Please note that you will need the app to view the information. file manager(for example, ES File Explorer). You can download it from the official store Google Play market. Without it, the system will not recognize the flash drive. In the same way, you can connect a keyboard, mouse, and other gadgets to your device.
- If your tablet does not use a MicroUSB input, then you should look for an adapter either from it to MicroUSB, and only then install an OTG cable, or find it right away for your input similar solution. The latter option is more preferable: in the first case, you will have as many as two cables and plus the flash drive itself. Carrying such a structure with you will be quite inconvenient.
With Android devices, use an OTG cable through which you can connect a USB flash drive Windows
- Consider yourself the luckiest of all: most tablet computers that run are equipped with a USB input. It turns out that you just need to insert a flash drive there and use it as usual.
- If the tablet itself does not have such an input, then check the docking station with the keyboard, where the manufacturer usually places USB. Then you will need to install the PC on the docking station, and only then connect the drive.
- If neither the first nor the second case applies to you, then the instructions from the first paragraph of the block for Android devices will come to your aid. It provides for the purchase of an additional cable that will support the user in carrying out the operation.
