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.

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.

1, use of the data line about specific use before the steps and methods. Familiar with the use of the data line method and procedure, not because the use of data and make cable improper damage;

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.

Abnormal signal attenuation means that the signal has been on the wire, but the signal strength in reducing There are many reasons to cause this problem, the main line connection or the cable is too long. The table below is the technical specifications of the cable length. This is the standard maximum length of a variety of connection. Remember that these standards, if your cable connection does not exceed this standard, you still encounter the problem of signal attenuation, you should check the cable itself. Any unnatural bending or inappropriate terminal will cause signal attenuation.

Ethernet cable summary

Technical specifications of the maximum length of cable type

10BaseT unshielded twisted pair 100 m

10Base2 thin coaxial cable 185 m

10Base5 thick coaxial cable of 500 m

The 10BaseF fiber 2000 m

100BaseT Unshielded Twisted Pair 100 meters

100BaseTX Unshielded Twisted Pair 220 meters

For unshielded twisted-pair crosstalk will surely lead to serious problems as well as signal attenuation. Reduced isolation or barrier between the two signals in two pairs of children the cable signal interference, so it was a cross-talk. Also occur when the same cable used for a variety of connection crosstalk. Standards Organization This phenomenon is called a short circuit. CAT 5e and CAT 6 cables, terminals generally have four pairs of children line. For some connections, I have seen a data connection only two pairs of children line. The other two children line for the data connection. This connection method does have a problem. When this signal is encountered on another line noise signal when the signal is transmitted on these lines, there will be crosstalk. If the USB Data Sync Charger Cable Cord For HTC EVO 4G Sprint is laid on the right, crosstalk, and abnormal signal attenuation would not have happened.

Using the correct connection method and attention to detail, the high transmission frequency should not encounter problems. Only poor-quality connections and facilities will need high transfer rate caused by network anomalies.
