The phone does not see a microSD flash drive: what to do, how to fix it?

Often owners of Android devicesface an unpleasant problem when the phone does not see the microSD flash drive. What to do in this case, what methods of elimination of the problem to apply? To begin with, determine the root cause and analyze possible situations.

Why can not the phone see the microSD?

Needless to say, the reasons for such disruptionscan be any number. There are program failures of the system itself, and the banal lack of contact between the memory card and the card reader, and violations in the file system of the USB drive, and even physical damage.

However, the situation may look twofold. On the one hand, this may concern a newly purchased card, but on the other hand, the problem may be that over time the phone has stopped seeing the microSD flash drive. What to do in this case, now and will be considered.

By the way, the issue will not be discussed herecompatibility of the card and the phone itself. This is worth paying attention to separately, because obsolete gadgets are not able to determine the SD-cards of the latest generation. Moreover, it can also be that the memory card is larger than the one declared in the device support. So in this case the card is not defined.

The phone does not see a microSD flash drive: what should I do first?

If you have problems with an already installedmemory card, no matter how trite it sounds, the reason may be the usual pollution of the device, say, getting dust. Agree, not every user is constantly cleaning his phone.

Here the output is the simplest: pull out the card from the phone, wipe the contacts on the flash drive and on the card reader, and then insert it again. Incidentally, this option is suitable for new maps. Well, you never know, the contacts just did not work. Therefore, do not rush to flee to the service center or throw out the card you just bought.

Using the Recovery Mode

If the simplest manipulations with contacts are nothelp, you can use a special recovery mode (Recovery), provided in any Android-device, although you can start a normal reboot first.

To access the mode we need, we usesimultaneously hold down the power buttons and decrease the volume. This is the most common option. But, in principle, each manufacturer can himself appoint another combination. The point is not this. After the start of the device, a special service menu appears, where you need to select Wipe cache partition, after which you just need to reboot the device. If, after this, the phone does not see MicroSD, we turn to more effective measures. They will radically differ from previous steps.

Problems with the microSD card on the computer: what can I do?

Well, firstly, it is worth noting an exceptional situation in general, when both the computer and the phone do not see the microSD flash drive. This is worse. On the phone, this problem is almost never corrected.

To start, you need to insert the card into anotherdevice or computer and make sure it is working. If it is detected, the problem is only with the phone or the names of the disks on the computer. If the card is not detected, the problem is either with the file system or with the memory card itself.

So, first you should use the controldisks, which in Windows are called quite quickly. You can use the combination of Win + X with the subsequent choice of disk management or enter the command line diskmgmt.msc in the field of the "Run" menu bar.

This method is good because in the main window there will beabsolutely all connected disk devices are displayed, even unformatted ones. It is quite possible that the literature of a removable card, for example "F", coincides with the designation of an optical drive. Right-click on the map and select the letter change command.

However, after such an operation, too,There will be a situation when the phone does not see the microSD flash drive. What to do, because it is already recognized on the computer? The simplest way to fix the situation will be partial or full formatting of the media. However, full formatting with the removal of all data and the re-creation of the file system still looks preferable.

It can be produced either here or fromstandard "Explorer". In both cases, the right click brings up the context menu, where the format string is selected. In a new window, remove the tick from the quick formatting, and then specify the creation of the FAT32 file system. But, in principle, FAT32 is installed by the system by default. Now it remains to confirm the start of the process and wait for its completion. After that, you can safely insert the card into the phone.

Recovering the microSD card

Now a few words about one more situation, when the phone does not see a microSD flash drive. What to do if it is detected on the computer, but not on the mobile gadget?

First, you must connect the card again.computer and laptop and conduct a standard device check for errors. We use the same "Explorer" with the subsequent transition to the properties menu. There we select a section of the service and check the disk with the mandatory indication of automatic error correction. Also, although it is not necessary, you can use a surface test with automatic recovery of damaged sectors.

Another option involves a correctionaccess to the memory card on computer terminals, as well as the normalization of the parameters and keys of the system registry in the HKLM branch. You should find the SYSTEM directory in the directory tree where the StorageDevicePolicies directory is located. On the right side, the defining parameter must be set to zero (usually 0x00000000 (0)). After that, the problem should disappear.

Finally, if the card has minorphysical damage, which is usually associated with a malfunction of the microcontroller, you will have to look for special utilities for formatting, having previously learned the parameters of VID and PID. The same can be done with the help of special programs, such as USBIDCheck, or by disassembling the card (where the data is indicated on the internal microcircuit).

Then, from the Internet, for each card of a particular manufacturer, according to known parameters, the program is downloaded, and then the formatting is performed.

Conclusion

If for some reason the removable device does notit is determined, it is not necessary to panic. First you need to determine the root cause of the failure. As practice shows, any of the proposed methods helps to solve the problem. Speaking specifically about phones, the cleaning of the device from pollution, the formatting of the card or the restoration of operability, as it was described in the last version, is more likely.

By the way, the question was not considered herecompatibility of the card and the phone itself. This is worth paying attention to separately, because obsolete gadgets are not able to determine the SD-cards of the latest generation.
