Disc repair technique

At present, the use of U disk is very common, and people often

use U disk to backup, carry and transfer files. However, if the

U disk from port USB pull out before, forget the uninstall

uninstall * *, or not completely, or due to incorrect operation,

and directly to the U disk from USB mouth pulled out, there may

cause damage to the U disk, sometimes leading to the computer

can identify the U disk. If you haven't had any experience

dealing with this situation before, you'll probably think that

the U disk is no longer available and should be thrown into the

bin, but it's too bad.

Is there any way to restore the functionality of the U disk?

The answer is yes, you can follow these steps:

Turn on the control panel, administration tools, computer

management, storage, disk management in turn, right-click on

the word "disk 1", select "initialize disk", click "OK"". When

initialization is complete, the status of the U disk becomes

"online" state. Note that the lock on the U disk is open at this

time, otherwise the following prompt will appear: "because the

media is protected by writing, the requested" * "cannot be

completed." Right click on the right side of the white box,

select "new partition", enter the New Partition Wizard, click

next, select the partition type (primary partitions, extended

partition or logical drive), generally choose the primary disk

partitions can be. (Note: the following dialog box will appear

in sequence, so the screen copy is not here.)

Next - select disk space capacity: generally use the default

size.

Next - assign a drive letter (or not).

The next step - select the following settings format this

partition settings form (file system type, allocation unit size,

volume) (do not use fast format).

Next - complete the formatting wizard successfully. Click

Finish to wait for formatting to complete.

When the formatting is complete, the U disk status is displayed

as "in good condition", that is, done.

This repair method can generally restore the U disk. However,

there is a drawback to this method of repair, that is, the

original data on the U disk cannot be recovered. This method

is relatively useful if the original data on the U disk is not

very important. If there is a very important document on the

U disk, it must be restored, and it is recommended to go to a

professional company. Now major cities are basically

professional companies that do data recovery.

How to remove write write protection for MP3, U disk, hard disk

and other storage devices?

I U disk are being added to the write protection program,

do not know how to deal with, please enlighten

There are two kinds of write protection, one is hardware, that

is to say, write protection switch, and the other is software

writing protection, which is used to protect files in U disk

through management tools.

Delete method: 1. in DOS, enter the hidden file directory using

DIR/A to identify the hidden files under the DOS name (don't

forget the suffix), and then use the attrib command to remove

the relevant attributes of the file, the use of attrib: display

or change file attributes. ATTRIB [+R -R] [+A -A [+S | | | -S]

[+H -H] [[drive:] [path] filename] [/S [/D]] | + set properties.

- clear properties. R read-only file properties. A archive file

properties. S system file properties. H hide file properties.

/S handles matching files in the current folder and its

subfolders. /D also handles folders.

2. after entering safe mode, give full permissions to this

folder, and then restart it to delete the folder.

Maybe it's broken inside.

I have the mobile phone memory card inserted into the computer,

ready to download stuff said in a write protected disk ` ` how

ah? I can format

Did you set the password for your memory card on your phone?

If you set up a memory card password in your phone, you can't

use the memory card when you connect to the computer!

Insert a card into your cell phone,

Remove the memory card password and try using the computer!

Would you please tell me how to remove the write protection on

the removable disk?

Is that the U disk? There is a small slider next to the U disk

to push it aside.

I. conventional solutions:

1., delete or restart the computer, and then try to delete.

2. go to safe mode to delete".

3. use the DEL, DELTREE, and RD commands to delete them in the

pure DOS command line.

4., if there are more subdirectories or files in the folder,

which cannot be deleted, you can first delete the

subdirectories and files in the folder, and then delete the

folder.

5. end the process in the task manager and then

delete the file at the command prompt window.

6., if you have installed ACDSee, FlashFXP, Nero, Total these

several software, you can try to delete the folder in these

software.

Two, advanced solutions:

1. disk error

Run disk scan, and scan the file where the partition, before

scanning to determine the selected repair files and bad sectors,

a full scan all options, scan and then delete the file.

2. prefetch mechanism:

Some media will not be deleted when they are interrupted or are

being previewed. The input in the "run" box: REGSVR32 /U

, written off reading function. Or delete the

following key in the registry:

[HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{87D62D94-71B3-4b9a-9489-5FE6850DC73E}InProcServer32].

3. firewall:

Since antivirus software will take possession of the file under

review when checking, resulting in the deletion of the prompt

when the file is being executed, then try to temporarily shut

down its immediate monitor, which may be resolved.

, WPS series software:

Illegal shutdown of OFFice can also cause files to be deleted

or renamed. Rerun the program, then shut it down, and then

delete the file.

5. by means of WinRAR:

Right click on the folder you want to delete, and select Add

to the compressed file". In the pop-up dialog box, select "zip,

delete the source file", literally write a compressed package

name, point to determine.

6. permissions issues:

If you are 2000 and XP systems, please make sure that you have

permission to delete this file or folder.

7. delete executable files:

If not release call image or the executable file of the DLL

dynamic link library file is still in memory, delete will prompt

the file is in use, the solution is to delete the low car while

offering in98 Zhan sac prostitute is , Win2000/XP is

. Be careful to delete under DOS.

8. file shredding:

Using file shredder such as File Pulverizer, you can completely

remove some stubborn files.

Three, the production of a "can not delete" file safe"

The folder cannot be deleted, is not necessarily a bad thing,

if you put some important files in this directory, you can not

avoid the error? A folder whose name contains only spaces is

not allowed to create and delete in Windows, but under DOS it

is possible to create a folder containing the name of the file.

In the process of using Windows, we encounter a variety of

problems. Even the simplest delete file can be in trouble, or

the system prompts that the file is being used by another person

or program, or that the report is denied access"...... If you

have encountered this situation, you might as well look at this

article.

The reason: the file is in use

One of the frequently encountered problems when deleting files

is that the file is in use and cannot be deleted. If you try

to delete for exclusive access rather than to share access to

open, and is being used in the file, the system will appear error:

"cannot delete XXX: file is being used by another person or

program". In the other case, you can delete files using the

delete command, but before releasing the file process releases

the file,

The file was not deleted.

To solve the above problem, you need to determine the process

that owns the file and open the handle, and then closes the

process. In previous Windows, we can use the resource toolkit's

. But in XP, the installed Support

Tools without . However, XP provides a new

command line tool that reports each file opened by the process.

Similar to , also requires open system

kernel monitoring, which consumes some memory and reduces

system performance. The command to turn on system monitoring

is "Openfiles"

/local

"On", which enables the system global flag, maintains the

object list, and needs to restart the system to take effect.

When you restart the system and execute the "Openfiles" without

arguments at the command prompt, you can see the list of files

each process opens.

Reason two: file system Corruption

Bad areas on the disk, other hardware faults, or software errors

can damage the file system and cause problems with the file and

cannot be deleted. Typical operations fail in a very different

way. When a file system is detected, a message that runs Chkdsk

is usually received.

If this happens, you can run the Chkdsk utility on the disk

volume to correct any errors that are present. Depending on the

nature of the damage, Chkdsk may be able to recover the file

data and may not be able to recover, but Chkdsk can return the

file system to an internally consistent state. For commands and

arguments about the Chkdsk utility, you can execute Chkdsk at

the command prompt

/?" Refer to.

Reason three: the file uses the access control list

If a file uses the access control list (Access Control)

List, referred to as ACL), and the operator does not have the

appropriate permissions, then delete the file, there may be

"access denied" prompt.

Typically, the administrator has the implicit ability to obtain

any file ownership, and the file owner also has the implicit

ability to modify file permissions. However, these default

permissions can be modified.

To solve the problem that ACL causes files to be deleted, you

must login to the user with the appropriate permissions or to

grant permission to delete the file before deleting the file.

Note that the operator must have ownership of these files to

change permissions. If you are unable to use some security tools

to display or modify the power limit because the document is

using an irregular ACL, you can try using the command line tool,

, to modify it.

Reason four: the file name uses a reserved name

As you all know, names such as AUX and LPT1 are reserved for

older DOS devices. For backward compatibility, these file names

are not allowed in Windows, nor can a typical Win32 file tune

be used to create them. Conversely, if the file name is a

reserved name in the Win32 namespace, it is also possible that

this file cannot be deleted.

To solve this problem, you can rename or delete this file under

Linux or other non Windows operating systems. In addition, if

you can specify the path to the file using a specific syntax,

you can also use a few built-in commands to bypass typical Win32

retention name checks. For example, in Windows

Using the following command in XP, you can delete the file named

LPT1 (Del command followed by "?"" To prevent the Windows from

checking the validity of the filename:

Del c: file path LPT1

Reason five: Invalid file name

If the file name contains an invalid name, such as the file name

with a trailing spaces, or a trailing end, or the file name

consists of only one space, also may not be able to delete the

file. It is worth mentioning that, if you use the typical Win32

grammar to open the trailing spaces or trailing period file name,

trailing spaces or periods will be removed before the actual

file open. Therefore,

If there are two in the same folder, they are called

and

"File" (note the space behind the second filenames), and

actually open the first file when you open the second file using

the standard Win32 call. Similarly, if the file name is only"

(a space character) that actually opens the parent folder of

the file when it attempts to open it using the standard Win32

call. In this case, if you try to change the security settings

on these files, you might accidentally change the settings on

other files.

Similar to the way the solution file name is kept using a

reserved name, you can delete this file with an appropriate

internal syntax. For example, to delete files that contain

trailing spaces, you can use the following command:

Del c: file path (file name of trailing space)

Six reason: the file path is too deep to access

The file is located in a deeper path than the maximum path

character number (MAX_PATH), which may cause the file to be

inaccessible. Of course, this is rare. If the path is deep

because the folder name is too long, the easiest solution is

to use the automatically generated 8.3 name to access the file.

If the 8.3 path is too long, you can start renaming the folder

from the root folder and shortening their names so that the path

of the target file is not more than MAX_PATH. If the depth of

the file is more than 128 folders, you can access the file by

accessing the share by creating a network share so that it is

as deep as possible in the folder tree.

In general, you can manage these files by using software that

creates files when you encounter problems that cannot be

accessed because the file path is too deep. That is, if there

is a program that can create more than MAX_PATH files, we can

also use the program to manage these files. In addition, files

that have deep structure created by network sharing can also

be deleted by using shared access.

The front introduces several reasons why files or folders

cannot be deleted in the Windows system and how to solve them.

In some cases, you might encounter different combinations of

the above reasons, making the process of deleting files more

complex. This requires readers to draw inferences and apply

Microsoft's various utilities to solve them.

The problem of deleting AVI files in Windows XP

Many friends may encounter problems with AVI files that cannot

be deleted in Windows XP, mainly due to Windows

XP video preview feature caused by Bug. You can try deleting

it in the following ways.

Method 1. Enter Regs-vr32/u in the run command box

and press enter, remove Windows

XP video file preview function. When you want to restore the

video preview function later, use the ""

command to register again.

Method two

First open the command prompt window, then end the Explorer

process in the task manager, then switch from the command prompt

window to the folder that stores the video file, and then delete

the file with the Del command.

Method three

If you install a dual system, you can delete it from another

system, such as Win98.
