After formatting the SD card, it still shows that the memory is insufficient.

Now there are two kinds of mobile phone memory: RAM

Dynamic memory, commonly known as running memory, is the same as the memory in a computer; rom

Formerly known as static memory, with the development of technology, now ROM usually refers to non-volatile memory, or in other words, they can still hold data when the system is out of power. Also known as mobile phone memory, it is used to store the mobile phone system and some user data (including the programs installed by the user), and the role is basically the same as the hard disk, but the hard disk is definitely not a ROM.

Usually, the phone prompts that the memory is insufficient, generally because the mobile phone has too many applications or too many mobile phone cache files, so it is good to clear the cache or close a few applications. The easiest way to free up memory is to turn it on after shutting it down. If it doesn't work, it's that the memory of your mobile phone is too small.

A smart phone is actually a small computer·· He also has a processor... Graphics·· Memory, etc., insufficient memory refers to the memory used by the mobile phone to run the process, which is equivalent to the computer memory, the SD card and the card that can store things in the mobile phone, the mobile phone memory card, which is equivalent to the computer hard disk, and the SD card is the extended memory, which is the ROM. Running memory, called RAM, is similar to a computer in that any software must be run in RAM. In layman's terms, ROM is the equipment room where things are placed, and RAM is a platform where these things are used.

There is a difference between these two. Therefore, there is a certain reason why a smart machine can also become a small computer.

Personally, I suggest that your next software is to occupy the ROM, that is, the SD card and the like as virtual memory, in that case, when you use it, the software will run a great improvement. Hope it helps.

There are two kinds of mobile phone memory, one is in the external SD card, and the other is a small memory of the mobile phone itself, which is used to store the system, so the reason why you can still use the mobile phone without an SD card is this, the so-called insufficient memory refers to the insufficient system memory of the mobile phone, not the insufficient memory of the SD card.

It is recommended to perform the following actions to balance:

1. Troubleshoot the memory card: right-click the memory card letter, select the "Properties" item to open its properties panel, switch to the "Tools" tab, and click the "Check" button. The system automatically checks for errors and then fixes them.

2. If there is no important data in the memory card, it is recommended to directly format the memory card.

3. The most thorough solution is to use mass production tools to mass-produce the memory card to restore the factory settings.

There are currently 3 levels of SD card capacity, which are SD, SDHC and SDXC.

Like other memory card formats, SD cards are protected by numerous patents and registered trademarks, and licensing can only be done by the Secure Digital Card Alliance. The Secure Digital Card Alliance's 2013 license agreement did not allow open source to proxy SD drivers, which has led to a lot of debate about open source** and free software.

The common practice is to develop an open-source** shell, but at the core is a platform-specific, closed-source** SD driver, which is too different from the desired open standard. Another common practice is to use the older MMC mode, because pure filial piety is based on the SD card standard, all SD cards must support MMC mode.

This means that SD cards are less open than CF cards or flash drives, and the above two formats are almost free of charge, requiring only a license fee to use the Union logo and registered trademarks. But much more open than an XD card or a memory stick, both of which don't offer public document support at all.

Summary. Reasons and solutions for the memory card prompt to be formatted 1. The gold finger of the memory card is oxidized. Just wipe it with a softer piece of paper.

2. The card reader is a problem, the place where the card reader and the gold finger come into contact is oxidized, and the memory card can be connected several times. 3. There may be a problem with the card reader, try a different card reader. 4. Finally, before pulling out the card reader, remember to safely remove the hardware and then pull out the card reader.

Expand dataWhen you use a digital camera flash memory card, USB flash card, etc. to store data, you often encounter the need to format the display when inserting a USB flash drive, and the data inside cannot be opened, but once formatted, the possibility of data recovery is not large. In this case, in many cases, it is not that the flash memory card or USB flash drive is broken, but the boot file is wrong, it cannot be booted correctly, and it cannot be correctly identified, in fact, the data in it is still there, and we can still get it back by taking certain measures. A free recovery software, which can perfectly recover all the data---partitionguru pro, select the storage path to start the recovery, the data is perfectly recovered, all are not lost, at this time we can rest assured that we can boldly format the flash memory card or U disk, and resume normal use after the format is completed.

If the memory card shows that it needs to be formatted, it is recommended to back up the important data in the memory card first, and then format it. Here are some commonly used workarounds:1

Use computer formatting: Insert the memory card into the computer card reader or connect the phone to the computer, open the computer explorer, right-click the memory card icon, select "Format", select the file system and format method according to your needs in the pop-up window, and then click "Start". 2.

Format with camera: Insert the memory card into the camera, open the camera menu, find the "Format" option, and select "OK Huaijia" to format. 3.

Use a professional formatting tool: Some memory cards may not be able to solve the problem by regular formatting methods, you can consider using professional formatting tools such as DiskGenius, Easeus Partition Master, etc., which can do a more comprehensive repair and repartitioning of the memory card.

Hello, glad to answer for you, if your memory card shows that it needs to be formatted, it may be because it has been corrupted or there is an error in the file system. In this case, it is advisable to back up all the data on the memory card first and then format the memory card using a disk management tool on your computer. Here are some steps:

1.Connect the memory card to your computer and open Computer Explorer. 2.

Locate the disk where the memory card is located, right-click, and select "Format". 3.In the dialog box that pops up, select the appropriate file system type (such as FAT32, NTFS, etc.) and click the Start button.

4.Waiting for the format to complete can take a few rough minutes or longer, depending on the size of the memory card and the performance of your computer. 5.

Once the formatting is complete, copy the backed up data back to the memory card. If the above operations do not resolve the issue, then the memory card may have been damaged by the Portable Attendant and need to be replaced with a new one. The above is my reply, I hope it can help you!

Try to change the card reader, if it doesn't work, it means that the memory card is defective, in order to ensure the normal use of the stored files, it is recommended to change the card.

Hehe, if you really can't get it, just change it, there's nothing you can do about it.

Like the USB flash drive, it is really not possible to mass produce.

Formatting a memory card is to initialize it, and it must be formatted before it can be used like other storage hard disks and disks.

Formatting is the work of initializing the disk, simply put, it is to divide a blank disk into small areas and number them for the computer to store and read the data. Without this work, the computer would not know where to write or where to read.

The concept of formatting was originally only applied to computer hard disks, with the continuous development of electronic products, many memories have used the term "formatting", in a narrow sense, it is equivalent to data clearing, deleting all data in the memory, and restoring the memory to its initial state.

The hard disk must be partitioned before it can be used, and after the disk is partitioned, the next step is to format the hard disk, and the hard disk must be formatted before it can be used.

Formatting is the creation of tracks and sectors in the disk, and after the tracks and sectors are established, the computer can use the disk to store data.

- You can format the mobile phone card by inserting it into the card reader, formatting it on the computer, or inserting it into the mobile phone and formatting it with the program in the mobile phone.

For these two methods, it is generally better to choose the latter, because it can ensure that the formatted file system can be recognized by the mobile phone normally.

There is some truth in what the landlord said.

Probably poisoned.

If the phone can't be formatted.

Just format it on your computer.

Don't ask for the files in the card.

It is recommended that you use the card after detoxifying.

The watchtower lord adopted.

Change to a different mobile phone, it's best to set up a miscellaneous brand, that's how I got it......Hope it helps.

Then you can connect to the computer and delete it all with the computer! There will be a little bit of memory that you won't have if you don't have anything.

I have also had this kind of problem, how can it be formatted on the mobile phone, you can use the card reader to connect the card to the computer, format it on the computer, it is not enough, just see if your card reader is locked (TF card needs card slot, SD card does not use card slot, the card itself can be locked), and then the small piece on the card that can be moved can be unlocked on it!

Hello: There are many reasons why it cannot be formatted.

1. Removable disks.

There is a file that is being used by an application.

2. There is a virus in the memory card.

Prevent formatting operations.

3 cards are broken. Suggestion: 1. Format in your phone.

2. Upgrade the anti-virus software.

Factory reset and then format.

I think the program installed in the memory card is running or running in the background, and it is OK to put it on the computer and use 360 to smash the file on the USB flash drive
