Is there a problem with my card reader? 10

If you can't read it after changing several card readers, it's not a problem with the card reader, but a problem with the card

The lock next to the USB flash drive is closed.

Generally, there will be a lock key next to the USB flash drive.

I want to access things into a USB flash drive.

You want to ensure that the USB flash drive is not locked.

Take a look at the card reader, if the card reader is fine, it should be a problem with the memory card (see if the memory card has a password, and delete the password if it is set).

If it's all right, it's a computer problem.。。。 Hehe.

1. A single card reader, if you don't insert the card, insert the U disk interface, it can be read, but double-click it can't be opened, because there is no storage space, so it must be used with the memory card.

2. If the card is inserted and still can't be opened, it should be the place where the card reader is inserted is broken. It is recommended to try a different card reader.

3. There may be a problem with the card, it is recommended to try a different memory card.

Answer hello According to the information you provided, I found for you that this is generally because the card reader is not in good contact after oxidation, so use an eraser to erase it. If the eraser doesn't work, or you don't want to change the card reader, it's because the memory chip on your card should be burned, and the card reader can't be recognized, so change the card. The card reader is not responding.

Or maybe your card reader has a lot of ports, and the port without the card is clicked on this reaction. If there is only one port, it means that the card is not plugged in tightly, and some of the contacts are not touched. The card reader is not responding.

The card reader can't read it out for the following reasons:

1. The card reader and the memory card are not in contact (you can insert the card reader into the computer without inserting the SD card to see if there is a prompt for an external device to be inserted, if there is, then the card reader is useful.) You can use an eraser to wipe the metal part of the SD card before inserting it.

2. The memory card is damaged.

3. The card reader is not recognized by the computer, and the driver can be installed.

4. SD card poisoning. You can do the antivirus or formatting operation by yourself.

If your memory card is in poor contact with the card reader or the memory card chip is worn, check whether the memory card chip is complete. Take a clean cloth to wipe the chip or change the card.

No means that there is nothing in your card is blank or only a folder left, if it is a blank you first click on the H disk attribute to see if there is a capacity display, if there is no card reader broken, there may be that you accidentally checked the memory card, I hope it will help you.

The card reader is broken, buy a new one.
