Install new Windows system has n kind of way, here, n > = 5.
The hard disk installation, cd-rom installation,dell latitude c540 laptop cpu cooling fan U disk installation, daemon tools installation, and Ghost installation, etc.
Today for the novice friends briefly say a few words with U disk or mobile hard disk installation Win7 two benefits.
1, installation speed
With normal cd-rom installed generally 20 to 35 minutes can fix, but the
use of USB mobile hard disk installation Windows7 is faster, general
new installed a no more than 10 minutes. Of course, U disk can also do,
just U disk copy in small files speed is too slow.
2, convenient adjustment computer built-in hard disk partition size
With external equipment installation Windows7 advantage is dell latitude c600 laptop cpu cooling fan
ok and optional heavy partition in computer hard disk, of course, do
you use a cd-rom installed also can realize, this contrast is to use
daemon tools or the hard disk installation way.
3, convenient to change Win7 version
CD in the medium to store things, improper safekeeping have Nick nullify
disc not to say, and still read-only, with USB mobile hard disk or U
disk won't have this problem, you can change, the installation
configuration files, want to install what version of the Windows7 or
Vista, oneself have the final say.
Appendix: USB mobile hard disk or U disk installation process introduction
1) in Vista or Win7,dell latitude c640 laptop cpu cooling fan
access control panel - management tools - computer management - disk
management in usb mobile hard disk partition point the right mouse
button, point "will partition mark for active partition".
2) will Windows7 installation disc (or iso file direct decompression, or
with deamon loading) all the files and folders copy directly into usb
mobile hard disk in on.
3) can start usb hard drive installation disc production completed,dell latitude c800 series laptop cpu cooling fan in the BIOS setup usb hard drive is started, the direct start installation procedures, so simple.
Don't need the third party software, also do not need cutting plate.
Principle is very simple, the first step is to write enable information.dell latitude d400 series laptop cpu cooling fan In the Vista/Win7 next activation partition, it is write bootmgr, if the xp next activation partition, is write NTLDR.
Each user of the hard disk is depositing a lots of useful data, and
hard disk is a easy go wrong components. In order to effectively keep
the toshiba satellite l35 series laptop cpu fan
data in the hard drive, in addition to effective preservation of the
hard disk data, backup job beyond, learn to be in hard disk failure how
to life hard disk, or extract the useful data, the loss to the minimum.
1, the system does not recognize hard disk
kind of failure is common, that is, from hard disk can't start, from A
disk boot cannot enter the disk C, use CMOS of automatic monitoring
function also is unable to find the existence of the hard disk. This
kind of fault are mostly appeared in the connecting cable or IDE mouth
port, hard disk itself failure rate is very few,toshiba satellite l305 series laptop cpu fan
can pass to plug hard disk cable or change the IDE mouth and cable
replacement test, but soon found fault is. If the new grafted in hard
don't admit that there is a common reason is that the hard disk
master-slave line, if hard disk joint in the IDE Lord disc position, the
hard disk must jump is given priority to disk, jump line error cannot
generally be detection to hard disk.
2, CMOS fault caused by the
correct or not directly affects the normal use of hard disk, here
refers to the type of hard disk. Now that the machines are support "IDE
auto detect" function, can automatically detect the type of hard disk.
When connecting a new hard disk or replacement of the hard disk will be
after through this function to set up the type. Of course, now some
types of mainboard can automatically identify the type of hard disk.
When hard disk type mistake, sometimes simply can't start system, and
sometimes can start, but will happen error, speaking, reading and
writing. The hard disk type such as CMOS is less than the toshiba satellite l30 series laptop cpu fan
actual hard drive capacity, the hard disk behind the sector will be
unable to read or write, if it is multiple partitions status is
individual partition will be lost. There is another important failure
cause, because at present IDE support logic parameter type, hard disk
can use Normal, LBA, Large, etc. If the general mode installed the data,
and in the CMOS changed to other pattern, will happen the hard disk
read and write fault, because its physical geological mapping
relationship has changed, will not be able to read the original correct
hard disk position.
3 and the Lord direct program causes start-up failure
Lord of the hard disk boot sector of the hard drive is the most
sensitive one components, one of the master boot program is a part of
it, the segment of a program, is mainly used to test the correctness of
the hard disk partition, and determine the active partition, responsible
for the guide right over to the active partition DOS or other operating
system. This section program will not damage from the hard disk guide,
but from soft area or light area of hard disk after reading. Repair the
fault of the methods are simple, use high version of DOS fdisk the most
convenient, when band parameter/MBR run time, it toshiba satellite l20 series laptop cpu fan
will directly replace (rewrite) hard disk master boot program. In fact
the Lord of the hard disk boot sector is the program to create, fdisk.
Among the exe features a complete hard disk master boot program.
Although DOS version constantly updated, but hard disk master boot
program there has been no change, from DOS 3. X that there is winDOS 95
DOS, so as long as find a DOS boot disk boot system and run the program
can repair. In addition, as kv300 and other tools software also has this
4, partition table error guiding start-up failure
table error is hard disk of serious mistakes, the degree of different
error can lead to different loss. If there is no active partition mark,
then the computer could not be started. But from soft area or light area
after the guidance system of hard disk, speaking, reading and writing,
but through the fdisk reset active partition for repair. If it is a
partition type error, can cause the loss of a partition. Partition table
on the fourth bytes for partition type value, normal guidable more than
32 MB of basic DOS partition value for 06, and extended DOS partition
value is 05. If the basic DOS partition type to 05 cannot start system,
and can't read and write the data. If the 06 to DOS not to know other
types such as efh, the DOS think changed zoning not DOS partition, of
course, can't, speaking, reading and writing. Many people use this type
of value to realize a single partition encryption technology, back into
the right type of value can make the partition returned to normal.toshiba satellite c640 series laptop cpu fan
The partition table and other data used to record partition starting or
terminate address. These data will cause damage to the partition of
chaos or missing, generally unable to manual recovery, the only way is
to use backup partition table data to write back, or from any other of
the same type and the same hard disk partition condition get partition
table data, otherwise will lead to other data permanent loss. In the
master boot sector for operation, can use nu tools such as software, the
operation is very convenient, can be directly to the hard disk drive
master boot sector for reading and writing or editing. Of course also
can use debug to operation, but the operation trival and has certain
5, partition effective mark error caused by the hard disk failure
the hard disk master boot sector there are still an important part,
that is the last two bytes: 55 aah, this word is a useful indicator of
the sector. When from the hard drive, floppy or light area which, when
activated, will test the two bytes, if present, think it is hard disk
exist, or will not admit that hard disk. This symbol from hard disk boot
will turn into ROM basic or tip into the floppy disk. From the floppy
disk boot can't turn into hard disk. Here can be used to the hard disk
encryption technology. Can use toshiba satellite c630 series laptop cpu fan
debug method recovery processing. In addition, the DOS boot sector is
still have such marks exist, when the DOS boot sector without guide
sign, the system startup will show: "missing are automatically
notified". The repair methods can use Lord boot sector repair methods,
just address is different, more convenient method is to use the
following DOS system general repair methods.
6, DOS guidance system caused by the start-up failure
boot system mainly by the DOS boot sector and DOS system files
composition. System files including iosys, msdos. Sys, command.com,
including command.com is DOS shell file, usable and other similar
documents to replace, but by default is DOS startup the necessary
documents. In Windows 95 carry DOS system, msdos. Sys is a text file, is
to launch Windows must file. But only start DOS can need not this
document. But the DOS boot when something goes wrong, from the floppy
disk or CD guidance system, and then use sys c: transfer system can
repair failure, including the boot sector and system files can be
restored to normal condition.
7, fat table caused by the fault, speaking, reading and writing
table records the hard disk data memory address, each file will have a
set of connection of fat chain designated the deposited cluster address.
Fat table damage means the loss of the contents of the documents. The
good news is DOS system itself provides two fat table, if the current
use of fat table is damaged, it can be the toshiba satellite l675-s7018 laptop cpu fan
second to cover repair. But as a result of different specifications of
disk its fat table and the length of the two fat table address is not
fixed, so must be correct repair find its correct position, by some
tools software such as nu etc itself has such repair function, use is
very convenient. The debug also can realize the operation, namely USES
the m ordered the second fat table moved to the first table place can.
If the second fat table also damaged, it also can't take hard disk
restored to the original state, but the file data still stored in hard
disk data area, can use CHKDSK or scandisk command repair, and
ultimately the *. CHK files, this is lost fat chain sector data. If it
is a text file can be extracted from it and can merge complete file, if
it is binary data files, it is hard to recover the full file.
8, list damage caused by the guide fault
record the document's filename in the hard disk data, of which the most
important one is the file starting cluster number, list since there is
no automatic backup function, so if directory damage will lose a lot of
documents. A kind of reduce the loss method is also used the above
CHKDSK or scandisk program method, from the hard disk,toshiba satellite l675 laptop cpu fan
search out CHK file, the list when damage is the first cluster number
is missing, in fat for damaged cases by the formation of the CHK file
usually relatively complete file data, each CHK file is a complete file,
its instead of the original name can restore most file.
9, error when deleted partitions data recovery
using fdisk deleted after hard disk partition, the surface phenomenon
is the hard disk data has completely disappeared, in has not formatted
in hard disk will be displayed invalid drive. If know fdisk work
principle, will know, fdisk just rewrite the hard disk master boot
sector (0 level 0 way 1 sector) the content. To be specific, delete the
hard disk partition table information, and hard disk partition of any of
the toshiba satellite l675d-s7013 laptop cpu fan
data are not change, can imitate the partition table wrong repair
methods, i.e., trying to restore partition table data can restore the
original partition namely data, but it only in addition to partition or
reconstruction after the partition. If have partition with format
formatting, earlier recovery after division, in according to the
following method restore partitioned data.
10, false to format the hard disk data recovery
the DOS high version condition, formatting operation format in the
default state have established the used to restore format disk
information, is actually the disk the DOS boot sector, fat partition
table and list all the content to the toshiba satellite l675d-s7012 laptop cpu fan
disk copy last few sector (because the back of the sector rarely used),
and the contents of the data area did not change. So through the
operation "unformat c:" can restore the original file distribution list
and list, and then the hard disk information recovery. Another DOS also
provides a miror command used to record the current disk information,
for formatting or delete the recovery of after use, this method is more
Computer hard disk is more easy to damaged parts, but there are quite a hp pavilion dv5-1009ax laptop cpu fan
part of the reason is that the user improper operation. In fact, as
long as in the daily use of the note a few skills, can reduce the
possibility of a hard disk failure, so as to prolong the service life of
1. Avoid power, speaking, reading and writing
The hard drive speed is mostly 7200 turn, in reading and writing, the
entire disc in high speed rotating state, if suddenly cut off the power
supply, will make head and disc violent friction, leading to the hard
disk appears bad way even damage. So in shutdown, be sure to note that
chassis panel hard light is no flicker, namely hard disk has been
completed, speaking, reading and writing after operation can be in hp pavilion dv5-1008ea laptop cpu fan accordance with the normal procedure to shut down our computers.
2. Prevent influenced by the vibration
Hard disk is very sophisticated storage devices, read and write
operation, head in the disc surface floating height only a few microns;
Even if not working, head and disc is also contact. Hard drive to work,
once produce larger vibration, easy to cause the head and data area
phase impact, leading to disc material area damage or scratches disk,
disk storage lost within the file data. Therefore, in the hp pavilion dv5-1008ax laptop cpu fan
work after shutdown or spindle motor has not pause before, don't move a
computer or mobile hard disk, in order to avoid head and disc produce
impact and abrade disc surface of the magnetic layer.
In addition, in the hard disk installation, remove the process also be
doubly careful, prevent excessive shake or and chassis plate violent
3. Away from magnetic fields
The magnetic field is damaged hard disk data invisible killer, so as far
as possible to make hard disk not near the strong magnetic field, such
as speakers, mobile phones, radio, etc., in order to avoid the hard
disk recorded data for magnetizing and damage.
4. Reduce frequent operation
If long time running a program (such as large software or play games),
would then attention, so head President time frequent reading and
writing the same hard disk position (i.e. program in the sector), and
make the hard disk produce bad way.
If, in addition, long time use of an operating system, also can make the hp pavilion dv5-1007cl laptop cpu fan
system files in the hard disk sector (not mobile) in long-term read
state, thus speeding up the sector damage speed. Of course, the best is
equipped with two or more operating systems used alternately, in order
to avoid to the hard disk drive a sector do long-term read-write
5. The use of appropriate time
In the day, had better not let hard disk of working time more than 10
hours, and don't continuous work more than eight hours, should after
using period of time will shut down the computer, let the hard disk has
enough time to rest
6. Regular defragmentation
Hard work can often read and write operation, and the program of add, hp pavilion dv5-1007ax laptop cpu fan
delete also can produce a large number of discontinuous disk space and
disk fragments. When the discontinuous disk space and disk fragments an
ever-growing number, will affect the hard disk read efficiency. If the
data additions operation more frequent or often change software, it
should be every certain time (such as a month) will run Windows system
comes with disk fragments finishing tool, carries on the disk fragments
and discontinuous space restructuring work, will the performance of the
hard disk play to the best.
7. Increase the memory and good power supply
If often use some memory needs a lot of software (such as image
processing, model design software), it should increase the memory, to
reduce a lot of files on a hard disk exchange when the read and write
operation, thereby prolong the hp pavilion dv5-1005ef laptop cpu fan service life of the hard disk.
In addition, be sure to use performance and stability of power, if the
power supply not pure or power shortage, it would be easy to cause data
loss or even damaged disk.
Nowadays many new notebook computer dell latitude d830 laptop keyboard
has a built-in fingerprint recognition function, especially in the
Fujitsu xinji is more familiar, Fujitsu special joined a number of
advanced safety protection function, including fingerprint
identification function and data password protection function, would
like to propose is that fingerprint lock use function, because this is a
big selling point of notebook computer.
In the touch pad the mouse button around the middle of the a yellow
metal block, and that is the biggest selling point of the notebook, one
of the fingerprint recognition system. Embedded system is a kind of
recognition software, we can simply use finger to touch the identifier
will be able to boot, completely solve the password of trouble.
And recently, the outer fingerprint dell latitude e4300 laptop keyboard
identification card also appeared, the user can in any a PCMCIA
interface notebook grafted in fingerprint identification card, the use
of fingerprint identification function.
Fingerprint recognition is undoubtedly give notebook safety brought many
benefits, but use up also need certain skills, in use can appear often
because of the position of the finger put caused by the wrong not
through the verification. Especially in the registered fingerprints,
system still can ask you three consecutive input fingerprint, try to
coincidence to confirm identity, if every time the location of the
finger put different, can cause not compound dell latitude e5400 laptop keyboard
and registration no. The correct use of method is to hand the natural
bending on the notebook computer has a wrist and fingers and horizontal
probably into 30 degrees Angle, gently on the fingerprint recognition
system of the sensor.
However, due to the current induction technology is not very perfect, so
fingerprint identification now still exist some deficiencies. Sometimes
some of the more subtle like hand sweat, dust, hands dirty, finger cut,
even is a color of skin care products, etc., can make to recognition is
dell latitude e5410 laptop keyboard
not successful. Plus sensor is sensitive, and difficult to maintain,
but also often clean sensor, use rise also will run into some trouble.
And outside buy fingerprint identification card price is more expensive,
so now buy are not many.
To introduce "preview the Theft". Use of this kind of "preview the
Theft" software, when detect the thief mobile notebook computer, the
system in addition to will produce the alarm signal outside, still can
encryption has been already saved file, and in the BIOS level locking
computer operation, make the thief cannot use. Installation of the
software can distinguish the notebook computer dell latitude e5500 laptop keyboard
all the people at ordinary times with a thief handling the movement of
the subtle difference between, so as to identify stolen situation.
Really is very advanced oh, but I don't know will not give laptop users
in the use of, carrying with some trouble?
If the really lost notebook? At that time the above safety facilities
can save this fact! At this time, what we need is can help us to locate

The file system collapse, virus infection, hard disk controller failure sony vaio vgn-n270e/w laptop keyboard
and similar other disaster can lead to Windows unrecoverable error.
When appear this kind of circumstance, Windows to full screen, non
window text mode shows that the error information, this is the
well-known "bluescreen crash (BSOD)".
Whenever you appear bluescreen crash (code BSOD) error, the mistake will
send a Stop news, this is a brief error messages, prompt you may cause
for the wrong reasons. The hard disk of the causes BSOD mistake, will
send the following one of 5 kinds of different Stop news.
Stop 0 x0000007b or INACCESSIBLE_BOOT_DEVICE
This error message will only occur in Windows startup. There are two things will lead to the error:
Windows cannot be initialized hard disk.
Windows success initialization hard disk, but can't identify the data on the system volume.
I've seen this kind of error occurs reason is commonly due to the hard disk controller device driver sony vaio vgn-n270e/t laptop keyboard
collapse or not caused by right. (when system from SCSI drive or RAID
disk array which, when activated, this kind of situation is particularly
popular. However, the file system collapse, start zone and hard disk
virus or hardware problems can also lead to these mistakes. Even, when
in the new system of hard disk controller contains old firmware also
will find such a mistake.
Stop 0 x00000050 or PAGE_FAULT_IN_NONPAGED_AREA
In fact, this special Stop errors are not related with the hard disk,
more of the time, it was due to the internal memory caused by defects.
When the system tries to read data from memory, but can't find request
data, can produce the mistake.
When the error is due to the cause of hard disk to produce, usually, its reason can be ascribed to the sony vaio vgn-n250e/w laptop keyboard collapse of disk volume or hard disk cache memory defect.
Stop 0 x00000024 NTFS_FILE_SYSTEM
In the new generation of Windows version, this error message is usually
either because almost NTFS volumes on system files collapse, or is due
to the hard disk are bad block. Both of these two kinds of circumstances
which of the a, I suggest run CHKDSK tool, combined with/F switch to
correct this mistake. Although CHKDSK can repair a lot of hard disk type
of mistake, but use CHKDSK, must reinstall the latest Windows service
pack sony vaio vgn-n230e/t laptop keyboard(or
if the new service pack is not development, need to reinstall Windows),
in order to cover the original system files, present new version.
Old version of Windows produce this kind of error information reason is
different. If the share volume there are too many documents, AppleTalk
drive will trigger this error message. Use not compatible anti-virus
program or hard disk tools may also cause of this sort of error.
0 x00000077 or KERNEL_STACK_INPAGE_ERROR
This is another error message, and the produce this kind of mistake there are several reasons why.sony vaio vgn-n220e laptop keyboard
The mistake itself mean, system try from page file read data, but can't
positioning to the requested page. This is usually due to the internal
memory error or is caused by storage hardware problems, such as data
with loosen, SCSI termination is not correct or hard disk are bad
sectors. If another system component and hard disk controller existence
resource conflict, or is found that the virus, also can produce the
Stop 0 x0000007a or KERNEL_DATA_INPAGE_ERROR
Although this error is related to the actual page file data, not stack,
but in fact, this mistake is reduced to KERNEL_STACK_INPAGE_ERROR is a
kind of mistakes. The only real difference is that this mistake seldom
happen,sony vaio vgn-n220e/b laptop keyboard when the system in the paged pool resources shortage in operation, will not appear this mistake.
