How to read files with camera sd card

Unable to read the SD card on the camera.

First, the memory card problem.

A. the memory card is physically damaged.

If it is determined that the memory card is physically damaged, only another memory card can be replaced. If the memory card is inserted into another normal camera or card reader, it can be judged that the memory card is physically damaged.

B, metal contact problem on the memory card.

Both the metal contacts on the memory card and the contacts in the camera card slot may be oxidized to produce dirt. This will lead to poor contact, which will certainly affect the camera's reading of the memory card.

To deal with the dirt on the gold finger of the memory stick on the computer, first wipe the above parts with leather, and then wipe them with white paper, which can solve the fault caused by this problem.

Second, the SD card file system is wrong.

The file formats of computer system are "FAT32" and "NTFS", but the compatibility of digital cameras with the above file formats is not good, only the "FAT" file format is relatively stable and compatible.

You can format the memory card once on your computer.

If the above measures are ineffective, you can only consider changing the card.

Extended data:

Users who use SD to expand their mobile phones often encounter some distress. Sometimes the card is inserted several times, but the phone still can't read it correctly. The specific analysis is as follows:

(1)SD card chip is not clean.

Being stained with dust or oil, resulting in abnormal card reading. Observe whether the metal area on the card is dim or spotted. Gently rub the cotton cloth with alcohol or water, and then re-insert it when the water is dry.

(2) The battery voltage is unstable

Because good quality card reading requires very strict power supply, sometimes the battery bought in the market is used instead of the original electricity, which can easily lead to card reading failure.

In the case of using non-primary electricity, the standby state is not ideal, and it is necessary to doubt the cause of the battery. Try again with another motive force.

(3) Squeeze the slot

For some ultra-thin machines, the card slot is cleverly designed. If you use some irregular batteries in the market, the card slot will be squeezed when the thickness exceeds a certain requirement, which will lead to unsmooth card reading. Change the original electricity and have a look.

Still use the original electricity. And hold the card slot with something to move up and down.

(4) The conductor in the groove is rusted or excessively bent.

Because some card-reading mobile phones support hot plug, frequent card plugging and unplugging will lead to excessive bending or rust of the wires reading card data in the card slot.

Align the card slot with the sunlight and observe whether the wire contacts are at the same height. If they are not uniform, this may be the problem. Try to pick the wire down a little with a needle.

(5)SD is infected with virus.

For some smart phones, SD is infected with a virus on the computer, which will also lead to the inability to read cards normally.

Read SD on the computer and scan it. Format cards on computers or other low-end storage (such as cameras). ). If you format it on a computer, you should use the FAT format instead of the FAT32 format.

(6)SD card is not formatted normally

Just use the computer to redefine the file format according to the instructions and then format it. If there is a card reader on the computer, check the SD card, please be sure whether the check card format is FAT, because FAT32E680 can't recognize it.

(7)SD card is broken

Insert the card into the computer with a card reader. If you can read it, the card is good.

(8) There is something wrong with reading the mobile phone card.

The mobile phone is broken and can only be repaired.

Why can't the camera SD card read the pictures on the computer?

Personal suggestions and opinions for your reference:

1. Connect the camera's own data cable to the computer correctly. If the computer can't recognize your camera, you need to load the camera driver into the computer. After the computer can recognize your camera, open the camera letter displayed by the computer, open the folder where the photos or short films are stored, and import the photos or short films into the computer.

2. Put the camera memory card into the matching card reader, connect the card reader to your computer (the card reader costs more than ten yuan), open the folder where the photos or short films are stored in the memory card, and import the photos or short films into the computer. Using the card reader is convenient, fast and safe!

After confirming that the above 1 or 2 points are correct, if the situation remains unchanged, there may be the following reasons. Please try to analyze them one by one.

1. The camera driver is not installed on the computer, or the driver is not installed correctly.

2. Check whether the USB port and data cable contact between the computer and the camera is normal and reliable. You can try changing other USB ports on your computer, or try another computer.

3. The card reader can be directly connected to the computer to import photos, which is convenient, fast and safe.

4. Restart the computer before connecting the data cable or card reader. Open any window on the computer, select tools, folders, view and display all files and folders, and see if the files on the memory card are hidden.

Some cameras should be turned on after being connected to the computer.

The above situation is generally caused by a virus on the memory card.

Memory card virus treatment, confirm that the photo files on the memory card do not need to be saved or have been backed up, just put the memory card into the camera for formatting! Remember to get rid of the virus in the computer, or you will be infected when you connect again! Don't put the memory card into the computer, format it in other cameras, and don't need to use anti-virus software (anti-virus software will delete some original data on the memory card when deleting the virus on the memory card,) to avoid the hidden dangers that the camera can't identify the memory card.
