Will new hard drives in my hand, look at hard drive behind, in the middle of the cable, port and power line interface, there are two rows of pins, there are two small square thing on two pins, which is the jumper cap, it is the function of connecting two pins. Jumper cap can be drawn, had better use tweezers to pull out, so we would not bend the other pins. Jumper cap out after, can be inserted on any two pins, this creates a different combination.

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.

Start-up failure

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.

Fault phenomenon: the computer through the self-check report system error after connecting the power supply, use Fdisk command can't find the hard disk, enter the BIOS to see, in the "standard CMOS function" of the hard disk Settings, normal work display model of "IC35L060AVVAWA07 - O," but now turned into "IC# l0 5 & 7 avfa 0 0", and check the parameters of the hard disk, but nothing. After fill in manual operation parameters, exit the BIOS still can't find the hard disk, fill in the parameters is invalid.


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.

Buy a new memory card without formatting can not be used on the phone, but if you choose to format it the best phone (if the phone can not be qualified in the computer grid), so mobile phone folder (some would Kari file folder deleted automatically build, depending on the situation), can help you save unnecessary trouble. Formatted on a PC, then what folder do not need the phone identify with some functionality will be built folder (such as music, photography), Niyitegeka select FAT32 format is not recommended, should FAT format on the computer.

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.

Mobile phone data cable is used for the following purposes:

1, phone personalized pictures, ringtones uploading and downloading. Through the website pictures, ringtones download the file to your computer, and then use the cell phone data cable to transfer ringtones, pictures and other files stored in the computer to the phone memory. This way you have a phone line, your phone can be replaced at any time you like ringtones and pictures.

2, phone BUG self-repair, upgrade the machine software version.

3, part of the large memory phone, use the MMC / TF / MINI SD / SD cards and other machines, USB Data Cable For Sony TM506 can be used on the computer when the U disk to send you need MP3 ringtones, pictures, videos, 3GP movies, documents, can also back up important information on your computer to your cell phone inside and find not worry about data loss, so we are not afraid.

4 data cable to connect laptop (desktop computers), and GPRS handsets (CDMA1X mobile) wireless Internet data cables and computer, send and receive e-mail, chat, and other. Data cables in mobile phone market is divided into the following categories:

1) MBUS: low transfer rate (the data speed of about 9.6kbp / s), is mainly applied to the repair, unlock class software.

2) FBUS: (data speed of about 115.2kbp / s), is mainly used for wireless Internet access, ringtones, pictures, games and other transfers.

3) DKU-5: high-speed data transfer function (data prime speed of about 230kbp / s) USB Data Cable For Sony Ericsson TM506 structure is complex, high manufacturing costs, but support the corresponding supporting software and wireless high-speed Internet access.

4) FLASH (Brush line): Some computer that is connected to the computer, transfer pictures, ringtones, and can also be used to upgrade maintenance market mostly can only be used for maintenance upgrades, replacement phone software version, equivalent reinstall systems.
