The mp4 program is out of order, and I want to format it on the computer, but I can t get into 25

Use the chkdsk tool to try adding a DOS channel to the context menu. Create a new CommandPrompt under the hKey Classes Root Directory shell branch of the registry, change the default key value to Command Prompt in the right pane, and create a new key under the key Command, and set the default key value to k cd %1 in the right pane. In this way, there is a DOS right-click fast channel, or it may be a "command prompt", which means the same thing anyway.

Right-click on the removable disk, select the DOS channel (or command prompt), enter the DOS interface, enter chkdsk, press enter, if there is an error, then enter chkdsk f, and then follow the prompts to operate. Generally, there will be two different prompts, you try the first prompt to select n, enter, the second one to select y, enter, if not, both y, enter. Here's how I dealt with some hard drive errors, didn't try to fix the problem of moving the disk.

If it doesn't work, you can consider this: there is a problem with the interface, there is a problem with the cable. These two issues are also often the cause of errors in portable hard drives.

In addition, the driver is also a key factor.

The methods for different causes are:1Try 2Try a different computer3This one is more miserable, that is to say, it is scrapped, see if it can be replaced or warranted!!

Hope mine is helpful to you, thank you ......

If it's really a program error, even if you can connect to the computer normally, can you re-establish the program? Just like the computer BIOS flash, it is a truth, formatting is just formatting the storage disk, but you *** ah and other applications are not built on the storage disk, I don't understand those, only understand the computer, the best way is to find the manufacturer!

Grid it, and press another piece of software

Different brands of MP4** may be slightly different, but for the general MP4**, you can format it like a USB disk, pay attention to the formatting, the choice of file system, it is recommended that you see what format was before formatting (such as fat32, ntfs), choose the same file system format as before, otherwise your MP4 may not recognize the formatted storage space. The files in it,It should be the software or advertising that came with the manufacturer.,Loss shouldn't affect the use.,I'm afraid of losing it.,Just back it up.,Copy it back after formatting.。 Also, does the manufacturer provide you with mp4 management software?

If there is, it should be foolproof to format it with this software.

You first look at the disk you checked inRight-click attributes. See if it's 0 bytes. If so, you can't format it.

You right-click on my computer. Point management. There's disk management.

There should be a disk 0

Disk 1....You're going to have to just a hard drive).

Disk 1 is your *** disk f....See if it's 0 bytes. If so, go to after-sales.

If there is a size, such as: 1g

Then right-click on disk 1...There is a formatting.

Choose fat32.

It should be fine. If you don't want to, go to the after-sales service.

But it's generally good.

Try it on a different computer, and you have to pass in many situations, but it's not bad if you can pass it.

Try to fix the partition with some partition table repair tools, of course, this can only solve the software problem, the hardware problem cannot be solved.

1.The problem could be a hardware failure. Flash data loss or corruption. If it does not come out, it may be that the crystal oscillator is damaged. You can try a different crystal oscillator.

2.After replacement, if it is out normally, it is okay. If it is not coiled, please check if there are any electronic devices that have fallen off. If so, please find a weld with the same specifications.

3.If none of the above is possible, it is recommended to try to format it first, and then use a recovery software to recover the formatted data.

There is a certain danger, I am afraid that it cannot be completely formatted. So please do it in three or four.

In addition, the virtual machine group is on the product**, which is super cheap.

TV display, is it only the drive letter?

What are the tips for MP4 not opening?

Please describe the problem clearly.

"Firmware" is actually the inherent program inside MP4, which is equivalent to the operating system of a computer, and the operation function of MP4 can be realized with firmware. Your mp4 can listen**, play**, record, watch**, read e-books, ......All of these functions can be achieved by firmware.

Essentially, firmware is just a piece of software. It's just that this software is fixed inside MP4 and cannot be modified or deleted. That's why it's called "firmware".

For example, if you format your MP4, there should be nothing in it, but the MP4 itself, ****, **** and other functions have not disappeared, because the "firmware" that implements the MP4 function cannot be deleted by you even if it is formatted, and it is still functioning.

Another example is the newly bought MP4, you don't put anything in it, but the displayed "free space" is not as large as indicated (for example, the 2G MP4 may actually be less than 2000M), which is also because the existence of the "firmware" occupies a certain amount of space.

And "firmware upgrade" is actually to upgrade the program in MP4 to further improve its functions. For example, increase sound effects, improve crashes, increase supported formats, beautify the interface, and so on.

Said computer formatted for no reason? It should be a computer hard drive, right? I haven't encountered this situation of formatting for no reason, it may be a virus. Viruses for the sake of it, or you have made a mistake there that caused it to be formatted.

In the case of not writing data, it can be recovered with asyrecovery, which is super recovering ability. Finally, check your computer and erase all the unknown or unnecessary programs from your computer!
