Hello.

Today, one of the most popular types of media is a flash drive. And no matter what anyone says, the age of CD/DVD discs is coming to an end. Moreover, the price of one flash drive is only 3-4 times more than the price of a DVD! True, there is one small “but” - it is much more difficult to “break” a disk than a flash drive...

Although not often, one unpleasant situation sometimes happens with flash drives: you remove the microSD flash card from your phone or camera, insert it into your computer or laptop, but it doesn’t see it. There can be many reasons for this: viruses, software errors, failure of a flash drive, etc. In this article, I would like to stop on the most popular reasons for invisibility, as well as provide some tips and recommendations on what to do in such cases.

Types of flash cards. Is SD card supported by your card reader?

Here I would like to dwell in more detail. Many users often confuse one type of memory card with another. The fact is that there are three types of SD flash cards: microSD, miniSD, SD.

Why did the manufacturers do this?

There are simply different devices: for example, a small audio player (or a small mobile phone) and, for example, a camera or photo camera. Those. The devices are completely different in size with different requirements for the speed of flash cards and the amount of information. This is why there are several types of flash drives. Now in more detail about each of them.

1. microSD

Size: 11mm x 15mm.

MicroSD flash cards are very popular thanks to portable devices: players, phones, tablets. Using microSD, the memory of the listed devices can be increased very quickly by an order of magnitude!

Usually, when purchasing, they come with a small adapter so that this flash drive can be connected instead of an SD card (more on them below). By the way, for example, to connect this flash drive to a laptop, you need to: insert micsroSD into the adapter, and then insert the adapter into the SD connector on the front/side panel of the laptop.

2.miniSD

Size: 21.5mm x 20mm.

Once popular cards used in portable equipment. Today they are used less and less, mainly due to the popularity of the microSD format.

3. SD

Size: 32mm x 24mm.

Flash cards: sdhc and sdxc.

These cards are mostly used in devices that require a large amount of memory + high speed. For example, a video camera, a car video recorder, a camera, etc. devices. SD cards are divided into several generations:

1. SD 1 – from 8 MB to 2 GB in size;
2. SD 1.1 – up to 4 GB;
3. SDHC – up to 32 GB;
4. SDXC – up to 2 TB.

Oh, very important points when working with SD cards!

1) In addition to the amount of memory, SD cards indicate speed (more precisely, class). For example, in the screenshots above, the card class is “10” - this means that the exchange speed with such a card is at least 10 MB/s (more details about classes: https://ru.wikipedia.org/wiki/Secure_Digital). It is important to pay attention to what speed class of flash card is required for your device!

2) microSD using special. adapters (they are usually written adapter (see screenshots above)) can be used instead of regular SD cards. True, doing this always and everywhere is not recommended (precisely because of the speed of information exchange).

3) SD card readers are backward compatible: i.e. if you take a device that reads SDHC, it will read SD cards of 1 and 1.1 generations, but will not be able to read SDXC. This is why it is important to pay attention to what cards your device can read.

By the way, many “relatively old” laptops have built-in card readers that are not able to read new types of SDHC flash cards. The solution in this case is quite simple: buy a card reader connected to a regular USB port; by the way, it looks more like a regular flash drive. Price: several hundred rubles.

SDXC card reader. Connects to a USB 3.0 port.

The same drive letter is the reason why flash drives, hard drives, and memory cards are invisible!

The fact is that if your hard drive has a drive letter of F: (for example) and your inserted flash card is also F:, then the flash card will not be displayed in Explorer. Those. you go to “my computer” - and you won’t see the flash drive there!

To fix this, you need to go to the “disk management” panel. How to do it?

In Windows 8: press Win+X, select “disk management”.

In Windows 7/8: press Win+R and enter the command “diskmgmt.msc”.

Next, you should see a window that will show all connected disks, flash drives, and other devices. Moreover, even those devices that are not formatted and that are not visible in “my computer” will be shown. If your memory card is on this list, then you need to do two things:

1. Change its drive letter to a unique one (to do this, simply right-click on the flash drive and select the operation to change the letter in the context menu, see screenshot below);

2. Format the flash card (if you have a new one, or it does not have the necessary data on it. Attention, the formatting operation will destroy all data on the flash card).

Changing the drive letter. Windows 8.

Lack of drivers is a popular reason why the computer does not see the SD card!

Even if your computer/laptop is brand new and you just brought it from the store yesterday, this does not guarantee anything. The fact is that the store sellers (or their specialists who prepare the goods for sale) could simply forget to install the necessary drivers, or simply be lazy. Most likely, you were given disks (or copied to your hard drive) with all the drivers and you just need to install them.

In general, there are special programs that can scan your computer (or rather, all its devices) and find the latest drivers for each device. I have already written about such utilities in previous posts. Here I will give only 2 links:

1. Programs for updating drivers: ;
2. Finding and updating drivers:

Connecting an SD card via USB using some device

If the computer does not see the SD card itself, then why can’t you try to insert the SD card into some device (for example, a phone, camera, camera, etc.) and connect it to the PC? To be honest, I rarely remove the flash card from devices, preferring to copy photos and videos from them, connecting them to my laptop via a USB cable.

Do I need special programs to connect my phone to a PC?

New operating systems such as Windows 7, 8 are capable of working with many devices without installing additional software. Installation of drivers and configuration of the device occurs automatically when the device is first connected to the USB port.

For each brand of phone/camera there are utilities recommended by the manufacturer (see on the manufacturer’s website)…

1. Try connecting the card to another computer and check if it recognizes and sees it;

2. Scan your computer for viruses (). Rarely, there are some types of viruses that block access to disks (including flash drives).

That's all for today, good luck everyone!

SD file is corrupted

If, after installing the required program from the list, you still cannot open a file with the SD extension, the reason may be that it is damaged. The solution may be to find a new copy of the SD file you are about to open

SD file extension is not associated with the corresponding application

In this case, the easiest way is to use the tools built into the operating system for connecting the SD file with applications to support it. Double click on the file you cannot open - the operating system will display a list of programs that are likely to work with your SD file. Select one of them, or indicate on the disk the location where you installed one of the offers from our list. Windows should open the SD file using a pre-installed program.

The entry relating to the SD file in the "Windows System Registry" is deleted or corrupted

The SD file is infected with a virus

It may happen that a computer virus is filed under the SD file. In this case, it will probably not be possible to open such a file. Download any good antivirus program and scan the SD file. If the antivirus program detects dangerous data, this may indicate an SD file indication.

is a portable computer. The same computer as a desktop one and it has the same parts, only smaller in size. That's why laptops are more expensive. It can be compared to a mobile phone, and a regular computer to a regular home phone.

In order to open a disk or flash drive on a laptop, you need to insert them first.

Let's start with a CD or DVD disc:

Look at the laptop:

Either on the side or front there is a device for disks. It's called a CD or DVD drive.

To open it, you need to press the small rectangular button.

When you press this button, a click will be heard and the drive will slide out slightly from the laptop. Gently “help” him move out all the way. Then you need to literally “put” the disk on it, shiny side down, and “push” it into the laptop until it clicks.

After you have inserted the disc, wait 15 seconds: the disc may open on its own (this happens with discs on which movies and music are recorded). If this does not happen, open the My Computer icon. It is either located on the Desktop, that is, on the screen, or it can be opened from the Start button:

Then double-click the left mouse button on the “CD drive” icon (can also be called CD-RW, DVD, DVD-RW drive).

What is recorded on the disk will open.

Now let's learn open flash drives. They look something like this:

In order to open a flash drive on a laptop, you need to insert it into a special hole:

You will find several of these holes either on the side or at the back.

After you insert the flash drive into one of the holes, open “My Computer” (let me remind you, it is either in “Start” or on the Desktop).

A new icon should appear there. For example, like this:

This icon is usually called "Removable Disk". Double-click on it with the left mouse button. You will see what is written on the flash drive (files and folders).

Before removing the flash drive from the laptop, click on the special icon at the bottom right (next to the clock) once with the left mouse button.

The message "Safely remove USB storage device" appears. Click on it once with the left mouse button. The message “Hardware may be removed” will appear. Now you can remove the flash drive from your computer.

I'm embarrassed to ask what kind of phone it is? Well, in general, somewhere it should say Memory Card
On my Nokia I go to files and there Memory Card

well... you have to pass oO

ps. what is search, search is search

Current account, Internet banking and payment cards are separate banking services. At any bank First they will open a current account for you, then they will connect you to Ibank, then they will impose a card on you (themselves), because any operator has a task from above - to impose a second pension and a credit card, here you can safely send them the hell away.

Ignore comrades a la Isaul, who consider the bank to be something like a temple, where they did everything - thank you for that, otherwise you will end up with a 3rd pension and a pair of expensive credit cards in your pocket.

So put it aside, use online banking, what’s the problem?


It's worth a lot of money. Why pay if you don't have to?

• If I'm not mistaken there is Android 2.2. then there probably should be some kind of explorer or file manager there. You can also look in the settings
  people also advise just downloading and installing a file manager

  There is a disk drive, that's for sure

  And open it
  look for a hole in its panel
  where the drive is on the right side, a little lower, (the hole is about under a gypsy needle, a little smaller), insert it (quietly until you feel the latch), press lightly and the drive will slide out on its own.
  P.S. Never push
