Generally behind the hard drive or on the roof, is the combination of the jumper cap printed diagram, the Master is the meaning of the disc, Slave from disk. Can be set according to the combination of hard disk or from the disk.

Generally hard drive jumper are by default is set to the main plate, see set up on the status of the old hard drive, is the main dish, then put the new hard disk set from the tray as shown. Must be set to the main, from the plate to be used.

To fasten on the new hard drive into the case, look for an extra power plug, the original cable, middle and an interface that can put a new hard drive, that is to say, a data cable, up to answer the two hard disks.

Don't cover panel, the first boot, the test can be normal use, to shut down the cover panel, otherwise if you can't fully identified, is the problem of data and jumper cap.

In the use of computers in the process, we may meet the problem of computer could not be started. Cause the system startup of the cause of the failure there are many, many of which are related with the hard disk. Usually, when hard disk failure, BIOS will give some English tooltip. Because different manufacturers mainboard or different versions of the BIOS, given its tooltip there may be some differences, but basically is pretty much the same everywhere. Below we will to use more common Award BIOS for example, discuss how to use the given tooltip, judge and deal with the hard disk can't start fault method.

1. The Hard disk controller failure (Hard disk controller failure). This is one of the most common error message when appear this kind of circumstance, carefully check the cable connection plug whether there is any loose, attachment is correct or hard disk parameters set correctly.

2. Date error (data errors). When this happens, the system from the hard disk read data are not repair sexual errors or disk there are bad sectors. At this time can try to boot disk scanning procedure, scanning and correct sector, the logic of the error, if the bad sector are physical bad way, need to use special tools try to repair.

3. No boot sector on hard disk drive (No hard disk boot sector). This condition is probably hard disk boot sector is destroyed, usually because of hard disk system boot sector has been infected with the virus. Encounter this kind of situation must use the latest version of antivirus software complete cure system viruses, and then, with such as KV3000 etc with a boot sector recovery function of the software, try to restore boot record. If you use WinXP system, can activate "recovery console" and call FIXMBR command to restore the master boot sector.

4. Reset Failed (Hard Disk Reset failure), Fatal Error Bad Hard Disk (Hard Disk Fatal errors), DD Not Detected (no detection to Hard Disk) and HDD Control Error (Hard drive Control errors). When there is any more than a hint, generally is a hard disk drive control circuit, interface circuit on the mainboard hard disk or disk body internal mechanical parts appeared fault, for this kind of situation can only ask professional maintenance corresponding control circuit or directly replace your hard disk drive.

Bad word fault

Through the above study, o King of hard disk can't start to solve the trouble understanding, the King, of course, want to know is how to deal with her have bad word hard for. The teacher this period for King, introduce logical bad way and physical bad way fault and the corresponding maintenance. But in began before, the teacher will remind o King, do the work must be carefully.

Logic bad word

Appear logical bad way is in the computer daily use prone to a hard disk failure, logical bad way is actually the track on the disk check information (ECC) and track data and servo information does not match. Appear this kind of the main cause of fault usually because some program mistake operation, or is the sector of magnetic media began to appear unstable phenomenon aura. Logical bad way in general computer use in performance, it is an error occurred when file access or do hard disk cloning, when to go wrong position, because the popup error message window and cannot continue. Eliminate the logical bad way method is simpler, many special software such as: DM, NORTON's DISK DOCTOR and so on all can do it, but the most commonly used or Windows own "DISK scan" function. For FATl6 or for the FAT32 drive, can be in DOS real mode using Scandisk scanning disk, the system will be logical mistakes sector flagged, later in the access operation will avoid these sectors. Due to the use of the software method is relatively simple and also has the introduction, here also but more explained.

But, if use is NTFS partition and install Windows XP system, because it does not have Scandisk this tool, it can only use Chkdsk this tool the. Chkdsk tool will be used based on the file system, create and display a disk status report. In addition Chkdsk can list and correct mistakes on the disk. But if you don't take any parameters of words, CHKDSK will only show the current state of the disk in the drive, and won't modified any mistakes, error correction must be including/f parameters.

Physical bad word

Hard disk physical bad way is more common hard disk failure. In fact, it is because concussion, scratches, etc "hard" causes, some sectors - the magnetic medium lost magnetic memory ability and cause. Normally, such damage repair up are more trouble. Because, in the hard disk internal track list, this sector is marked as normal, but the bad way is physical existence. So, it can not through the scanning, formatting, low lattice or activate sector methods to eliminate them, we must put this sector to join Settings in the hard disk internal system territory, tell disk the track is not used to the hard disk of the control system in the visible range to eliminate the bad way. Of course, it need to use some special software, to ordinary users speaking maintenance some difficulties.

But some hard disk manufacturers association provide original tools, such as IBM and Hitachi DFT and western Data LifeGuard Diagnostics. These original tools not only scanning speed, accuracy and discrimination is very high also, able to deal with common hard disk physical bad word fault. So to the hard disk drive internal operation or original software more reliable, unless the original tools will not solve the problem, otherwise do not recommend using third-party tools.

Relative to the above the comparative advanced hidden way, for those who asked not to be high users, can through the "bad Disk partition device" FBDISK and Disk Genius that a combination of software and complete the bad road location make partition hidden task. The specific operation are briefly introduced as follows:

First of all, will be to download the software copy to a normal use computer C packing list down, again there are physical bad word hard as a second hard disk articulated in the computer. Then start to DOS real mode, and run Disk Genius Diskgen executable programs, and then click "Ctrl + Alt key combination, select the" hard "under the menu" second hard Disk ". Then you can see the second hard disk partition of the concrete. If want to redesign the hard disk, you can put all the partition are deleted, and then save exit.

Then run FB Disk, choose to detection of hard Disk and press "Y" start scanning. If hard Disk bad way there, the FB Disk will automatically show it in which sector and track. Scanned it can put all the bad way are listed out, and asked about whether to write hard disk. If press "Y" will be will be bad word hidden, and press the Esc key exit.

Then again Diskgen operation, then we can see that after FB Disk process after the Disk, the bad way place can present - kind of gray. Through the Diskgen again a little bit will hide physical bad way partition expand some. Finally, will these bad way all hidden in a partition, repair work is finished.

Two software used together because, after FBDisk process after the hard disk may have a lot of partition, and by the software itself up to 4 primary partition restriction, will lead to the consequences of hard disk utilization rate is not high. And through the Diskgen to cooperate, can solve this problem well.

Troubleshooting: the author first suspected that computers may in the logic bombs. In the logic bombs, floppy disk will find, but I can use a floppy disk. The author use floppy disk to restart, save before master boot record in the floppy disk MBR  contains partition table  v to the memory of the 100 h address, again write hard disk, but after the restart, computer is still report system errors, can't find the hard disk.


With the DOS version KV3000 anti-virus software F6 and F10 function of repair disk, KV3000 report find 55 aa, repair is not successful. Author USES KV3000 p8 view of MBR, and compared with the floppy disk backup MBR, found that the MBR is already ulterly changed, not only the last two bytes of the partition table (offset address for 01 fe maintenance ~ 01 ff) by 55 "aa" instead of "a2" 55, activity division of mark  offset address for 01 be ~ 01 bf  also from "8001" to "8002". The rest of the MBR about one third of it is modified. The author think of hard disk may be in the malicious virus, but the report don't have the name of the virus, more can't make it clear.

Have no a way, the author only examined the Hitachi 60 gb hard drive is ATA100 hard wiring, the cable is 80 core, could it be data cable is too thin a break or have the situation of the poor contact? Then the author USES 40 core cable replaced 80 core cable. Antivirus still use floppy disks start, first of all, the report found no virus!!!! With debugging software to write the MBR of backup hard drive, to success! Check the hard disk, in addition to disk C, the other D, E... Is back, and the data is in good condition. Reboot into the BIOS, hard disk type also normal, according to the parameters of the hard drive is also. Disk C is can find, but can't access, the original backup system disk C cloning back to disk C, after the restart, the computer is normal. Seems to be the cause of the fault is not a virus, but the hard disk of the cable have a problem! Then change a new 80 core data on your hard drive, hard disk still normal work until now.


Conclusion: why hard disk of cable and cable plug contact will cause the failure? After some thought, the author thinks that, may be used to transmit data in the data cable eight data cable of the second caused by the poor contact with plug. Poor contact, is to disconnect the cable, the bit number is 1, so write data on the hard drive, no matter what to write, this one is 1. Such as write C (binary for 1100), the actual writing of E (1110. Write 0 (binary for 0000), the practical writing is two (0010), and so on. In this case, the data of natural can't correctly in the MBR written to the hard disk, also can't modify the "stubborn" number. Hung up because of the hard drive this cable, vulnerable to the interference of outside, the potential may be zero, may to 1, then write the number is not sure, so when the BIOS automatic reconnaissance in the hard disk, wrong to report the model it is not surprising that the hard disk.

Purchase also should pay attention to some bad manufacturers or profiteers India Japan to modify the number with the capacity of the card fraud (such as the actual capacity of the card is 128M, he marked on the card to 512M or 256M) than the actual capacity , will not be copied. And now some new cards have been used, and there are many viruses use the best pre-formatted.

Phone memory card error for it in terms of the operation is likely to cause fatal injury or loss of data, and how to properly use it? Attention to four points:

1) your mobile phone data format, features well-known composition; avoid phone does not recognize the file out of the wrong card software injuries turn into hardware damage, of course, to become the latter is not a simple matter, time recurring long have hardware damage this possibility;

2) use authentic data cable, card reader to transfer data; That is the work of the power of the card should be stable, voltage peaks and valleys card Mishap most powerful. After the transfer of the phone, the transmission before the phone battery to have plenty of power transmission lines do not have poor contact, try not to operate mobile phones during transmission, computer systems do not have the virus;

3) Once the phone memory card through the card reader and the computer connection can not be free to unplug or disconnect the connection and reader. To use the computer system is shut down, disconnect it to remove the card. Experiencing computer crashes or broken open card in the connection process when you want to turn off the PC power supply can manually disconnect the connection to the reader; careful observation file copy reader indicator, though you copy has been completed, but if the lights are still flashing, is a file transfer, this case can not be forcibly disconnected and the connection of the card, using computer software disconnect is not the correct method of operation, to wait for instructions found on PC The light does not flash before normal operation; copies of the file try not to fill the capacity of the card, it is best to leave a little space on the card to be software protection;

4) custody and carry a cell phone memory card is also worth noting;, try not to carry a card to go to the power distribution room, electroplating factories, welding machine next and some departments of the hospital, such as: X-ray room, MRI, CT room, etc., or in advance packed into the metal box inside; there is moisture-proof but also worth noting that the memory card is not waterproof, the event water temporarily do not use, fully dry in a ventilated environment before using it.]]> Wed, 21 Nov 2012 19:11:29 -0500

① When encountered removable hard disk does not show we first check whether the mobile hard disk data cable connected to the computer and mobile hard disk no, sometimes not plugged in, the computer does not recognize the mobile hard disk more, another mobile hard disk USB connection good, we look to the host USB to accept whether adverse, a change in the interface to try, the front will not do, for the back and try again. Computer crash? Computers often crash how to do?

PS: Some computer front USB interface did not connect to the motherboard interface, leading to the front USB interface can not be used a lot, so this also needs attention.

②Ensure that the host computer USB interface is available, and the 50Ft SVGA VGA Monitor M M Male To Male Extension Cable and hardware connections are secure, mobile hard disk is still unable to show we can try to re unplug host US interfaces, wait insertion to try again, I encountered this The case began to access the computer prompts due to equipment access, but not see the mobile hard disk drive letter in my computer, but repeatedly re-plug a few results there.

③ First up to try to get another computer, if normal, is the matter of your system, if not normal, that is, your hard disk or hard drive USB cable. Find a good USB cable to try it first, or not work is the hard disk, repair, and general hard disk will not repair.

Own system from the Device Manager to see whether the abnormal icon in front of the mobile hard disk, such as the question mark exclamation point, you add new hardware, re-find, and check under the computer services whether banned service, it can not and do not know where the problem friend can restore the system to normal (eg: a key to restore or reinstall the system), and then connected to the test, most problems can be solved. There are problems ... the last time to see the BIOS settings or the BIOS back to factory settings, does not work, check your motherboard.

Two situations:

1) the computer's USB port itself is not a high-speed interface, and removable hard disk for high-speed hard disk, so even energized normal can display mobile hard disk; You can view the computer's USB port, general computers have several USB interface, if the pre-effect bad, as much as possible to use set USB, and is best connected to the USB interface on the mobile hard match. Tip the print spooler service is not running "solution!

2) mobile hard disk on the power supply requirements, if the computer's USB port is insufficient power supply mobile hard disk as lights, there will be speed, but to take power, and can not operate normally, of course, will not be displayed on the computer mobile hard disk drive letter.

Of course, the above is to ensure that mobile hard drive is good, if it is unable to determine whether the removable disk available notebook trial, because the notebook to a removable disk power supply is powered double-headed disk data by moving the line, in general, the mobile hard disk suddenly recognize the disk, there are several possibilities. First, check the USB interface, for the trial of a USB interface, if conditions change a computer test, to remind here, try to set the USB interface connected to the computer after, because the chassis front USB interface possible voltage instability. Secondly, removable disk cartridge, reinstall or replace a removable disk cartridge and data lines to try; Finally, if you exclude the above problems, there may be the fault of the disc body, should stop the energized try, if the hard drive is still in warranty went Warranty . Over the warranty period, and the data is not important, you can use the MHDD detect bad sectors, but to do the operation from the disk, in DOS, swept out of the red and green blocks, MHDD also comes with a repair function, you can try to use mobile hard disk repair tools for mobile hard disk repair, repaired recommended after this hard drive is not recommended to save important data, because this hard drive may have been faster problem can not guarantee that data can save long lost important data more harm than good.

We use the vast majority of mobile hard disk and U disk are using a USB interface is a plug-and-play type. We often use the USB device also may encounter a situation that does not recognize the mobile device, that can not find the drive letter of the USB device.]]> Mon, 10 Sep 2012 20:49:40 -0400 accessories USB data cable line or field sync signal line (13 or 14-pin) have a disconnection of a display mistakenly believe that the host does not have sent the signal, after 4-5 seconds automatically enter a low energy state.

2) power high-voltage charge of the sound, even if you remove the signal line, power indicator light is always green. This situation is generally the line scan circuit failure, did not produce high voltage.

3) when power is high voltage charge of the sound, no image on the screen, remove the signal line, the power indicator for a while turn to orange, accompanied by the sound of high-voltage discharge. This case to the circuit failure, the general is not coupled with an operating voltage of the CRT, then you can look at the CRT filament is lit. Is also possible that the gate voltage is not coupled.]]> Fri, 20 Jul 2012 20:49:24 -0400 Consumer Electronics
2, put interface should pay attention to the correct and corresponding pins. Data has two interface, a computer is connected, a mobile phone is connected, and their interface pins are different, and the pins is thinner, easily broken, when inserted in the interface must be carefully insert, otherwise the pins a broken, data also is useless;

3, moistureproof dustproof. The data were fine port pins, belong to metal kind products, very vulnerable to water and dust oxidation. Maintain undeserved, it is easy to let the water and dust into the USB Data Sync Cable For Garmin Nuvi 1450 inside, causing the data can not work normally, download speed nature also slow;

4, try not to let the data line curly. Many users like after using after data will be stored data curly up, actually this is wrong. Cable with plastic and aluminum foil is made of the shield, can't stand long song roll, long time of music volume will cause the outside of the data line plastic layer or internal aluminum foil shielding layer is damaged, reduce the service life of the data line.

Thus the whole, the first HDMI interface, followed by the DVI interface, and finally the VGA interface. First you should make sure the LCD TV video input, only VGA interface, then any a laptop capable of; If you have a DVI or HDMI interface, then buy a notebook, we should pay attention to pick!

Finally, if you would like to use the optical output audio signal, then we should pay attention to the selection of a notebook with Spdif optical output. (DVI and HDMI conversion, system conversion after only transmit video signals can not transmit an audio signal.)

Also note that the first set the TV to VGA input, and then set the display resolution TV to the second set extend the desktop to the monitor, a combination of keys on a laptop, usually Fn + a similar display pattern button, you can switch to the VGA output. Since the TV has a VGA port, it means you can use when the display, I think you should check your TV standard is PAL, or NTSC, change to try?

LCD TV now mostly with HDMI, the CRT, color and other video input interface, using the HDMI is connected to the computer and LCD TVs is the easiest and most convenient way. Notebook is equipped with HDMI interface is not a lot, so you must first look at whether your laptop has a HDMI interface. If so, you only need to buy a good quality 2X Premium 50Ft 15M HDMI Cable PS3 HDTV 1080P Adapter, you can use the LCD TV to play the video in notebook computers. Should be noted that most of the LCD TV can support 19,201,080 resolution, but the vast majority of notebook computers are unable to support such a high resolution, and connect my laptop and LCD TVs, you will need on a laptop settings.

As follows:

One in the desktop, right click on Properties

(2) to enter the Display Properties

Then select the Settings tab

Choose your LCD TV models in the display device, and select the appropriate resolution for the LCD TV, for example, 1,280,720 or 19,201,080 at the same time check the Extend my Windows desktop to the display options in order to allow LCD TV Buzhi Yu image distortion in the display of the contents of the notebook computer

In addition, in order to transfer the laptop audio to the LCD TV, then you also need in the Device Manager activate HDMIAudio equipment in order to achieve Pictures HDMI transmission.

If your laptop does not have a HDMI interface, then you have two lines of the traditional CRT 2 HDMI 10Ft Gold Cable HDMI F/F Adapter For 1080P HDTV and AUX audio line to connect the notebook and LCD TVs.

Cable choice is one of the vital link in the construction of the digital cell. Taken several options: 1, twisted pair;, coaxial cable;, fiber. From the practical point of view, twisted pair, due to price factors than the latter two cable has an advantage, but because it should not be used in the video needs, in addition to the theoretical length of not more than 100 m (transmit data), so after two 10Ft 10Ft 15Pin Monitor VGA SVGA M/M Cable 3.5mm Audio worth considering. Here I will list the advantages, disadvantages and applications of the three cables.

UTP

Can be used to transmit analog, digital signal, its broadband up to 268KHz, the digital signal, the baseband signal to send, up to several Mbps, such as T1 line data transfer rate up to 1.544Mbps, and can achieve 15km data transfer (an increase of the repeater), but not suitable for transmitting high-frequency data, such as video. Applicable to the choice of the point-to-point and multipoint.

Coaxial cable

Can be used to transmit video and data signals. Transmit analog signals, the frequency can reach 300-400MHz. High-speed data transfer rate can reach 50Mbps. The typical range of data transmission within 1km 10Mbps (tens of kilometers of transmission, but need to add a repeater). Its more expensive than UTP, but the number of devices may be limited to about 20-30 units. Suitable for transmission of video, data, etc., suitable for point to point, point-to-multipoint connection.

Optical fiber

Not only can be used to transmit analog and digital signals, but does not meet the needs of video transmission. Its data transfer rate up to thousands of Mbps. If you do not use the repeater, the transmission range can reach 6-8km.

Looking at the development of the wiring system at home and abroad in recent years, we can see three stages: a UTP stage. At this stage, the voice with the large-scale data communications can not be mixed to adapt to the data communication. 2 coaxial + twisted-pair stage. It can meet the user's data transmission and video needs, but need more access devices, the cost relative to many, and difficult future expansion needs. 3, the fiber stage. The final stage of what we call, at this point, the corresponding ancillary equipment better, the data processing power, and better scalability. In recent years, the development of fast, the price of access equipment is subject to adjustment, we can say that this step integrated communication stage.]]> Thu, 05 Apr 2012 21:59:32 -0400
