There is a problem with the MP4 system, why does MP4 show a disk error?

400KB may be the system firmware, you can create a new WinRar archive to see if the files in MP4 (because the hidden files and system files can be seen in the RAR) are similar to INF files.

autorun is a special killing tool.

Maybe some folders in the root directory of your original mp4 have been formatted by you directly and mp4 can't create itself, try to create a folder in the root directory, such as e-book is book or books, audio recording is record or records, etc., if you don't remember which folders, you can **finaldata or easyrecovery to recover formatted folders, may not be able to recover, but you can see the folder name.

If this method doesn't work, it is recommended that you call** to the customer service of the mp4 manufacturer, or you can go to the repair point to ask for the system. Thank you.

There is a problem with the system, only flash the machine, first go to the official website**firmware, if your machine is automatically upgraded, just put it directly on your mp4 on the line, this screen will appear the system is upgrading, and it will be ok in a few minutes, but if your mp4 is not automatically upgraded, the upgrade is very troublesome, you send it to the place where you bought it and ask them to upgrade, so that it is bad, even if they are bad, if you upgrade it yourself, it may not be warranted.

Summary. One. Do you copy files when the battery is low, many MP4s will prompt a disk error when copying files when the battery is low or low, especially when inserting an external memory card such as an SD card.

Two. If it is not the above situation, then you can only format it, and then use the recovery software to recover it.

Three. Find an MP4 manufacturer to solve it.
