Error 0x80070057. Error message 0x80070057 when backing up files in Windows 7

Although the operating system Windows 7 and is considered the most stable of all released by Microsoft, nevertheless, and at the most inopportune moment it can be crashed. One of the most common errors is 0x80070057, which is typical for several unrelated cases. Let's consider all problem situations.

Error code 0x80070057: the main varieties and causes

First of all, you should pay attention to the fact that a failure with the specified parameter can occur in a variety of circumstances. To correctly determine the nature of the failure, you need to look at the description (Windows error codes in this case will look exactly the same).

As for the narrative, here you can find a few basic options, among which the most significant ones are distinguished:

• Incorrect parameter setting;
• Unexpected failure during copying;
• Impossibility to format a hard disk, partition or removable media.

This can be attributed to purely technical problems when error 0x80070057 appears due to disruption of the hard drive during the normal copying or moving of files, RAM or even incorrect recording of the installation or backup image on a removable media. But this is more of a cause, not a consequence.

Since we are interested in a failure related to backups, we will consider the first two items of the list listed (it is such descriptions that can be found when trying to create a backup of individual user files or the entire system as a whole).

Error 0x80070057: fix by the simplest method

Strangely enough, it looks like, but often this failure is associated with the wrong setting of the decimal separator parameter in the language settings and regional standards. Correct mistakes of this type can be quite simple.

To do this, first enter the standard "Control Panel" and find there the above section, then use the format section and configure additional parameters. Here it is necessary to find a string with a decimal separator, where the point should be. If another character is installed or not at all, you just need to drive a point, save the changes and reboot the system.

Troubleshoot the problem through the system registry

Another technique that allows to fix errors with the common identification 0x80070057, is the addition of special parameters to the system registry. With such actions it is necessary to be extremely cautious. Before adding keys, it is desirable to create a backup immediately (if possible). If error 0x80070057 occurs and when trying to save a copy of the registry, use the following steps.

After entering the editor through the regedit access command in the Run console (Win + R), and in the HKLM branch through the Software group, you need to find the Policies section. There is a Microsoft folder in which the System directory resides.

In the editing menu, we use the "Create" command or we call the similar action with a right-click on an empty spot on the right side of the screen, then select the creation of the DWORD parameter, taking into account the installed system (32 or 64), then enter CopyFileBufferedSynchronousIo. Then again use the right click on the created key and select the change command. In the value field, set the unit, confirm the changes by clicking the OK button and close the registry. In most cases, error 0x80070057 disappears when copying files (backup creation).

Incorrect image recording

Sometimes such a malfunction may appear at the backup stage, if you write directly to removable media (flash drive, CD or DVD discs), and at the stage of system installation. This is due only to the fact that the image was written (or created) incorrectly.

To begin with, you should check the checksum of the images. To do this, you can use the universal utility HashTab, which adds an additional tab to the file properties window. If you create a copy first on the hard drive, you need to compare the sum of the images on the hard disk and on the removable media. If they do not match, the image needs to be re-recorded on the media again. In the case when the installation image was downloaded from the Internet, the reconciliation should be done according to the values indicated directly on the site from which the download was made.

Problems with hard disk and RAM

Another reason for the failure may be errors on the hard drive or problems with the operability of the memory slots.

Not to mention the incorrect or loose physical connections to the motherboard, in the case of a hard drive, it should be checked for errors with the command chkdsk c: / r in the command line console and on the presence of bad sectors (it is better to use programs like Victoria).

Problems with memory can be identified if you use a special utility called Memtest86 +, which is by far the most powerful in this regard. Then it will be necessary to take out the strips one at a time and put them in place, overloading the system and checking its operability.

What in the end?

As can be seen from all of the above, the occurrence of error 0x80070057 should not cause special alarms, since it is eliminated quite simply. However, there are also situations where the occurrence of such a failure can lead the user in the wrong direction in terms of eliminating the error. Some mistakenly believe that the main problem is the automatic system update service (unfortunately, it is for that reason that there are many links on the Internet). This is not true. At the update stage error 0x80070057 is extremely rare, and the failure itself is usually associated only with the inability to copy files to the hard drive. At the same time, this situation has nothing to do with backup, and attempts to disable the automatic update do not lead to anything. In any case, even with the same fault codes, you first need to look at the problem description. If they are related to the impossibility of formatting, you should first check the same removable media for physical damage and only then proceed with the re-formatting. In the event of a hard drive failure, you can use the unique test-and-recovery program HDD Regenerator.
