Cell phone jammer has another feature of high cost performance

Others hit by a variety of unusual causes of physical damage. When the hard disk bad sectors, you may slow down or even hard to read and write errors, sound anomalies, can not boot from the hard drive or can not perform advanced formatting and other symptoms, in severe cases will result in the entire hard drive can not be used to boot the system. Hard disk bad sectors, the most simple test is to use the system comes with the disk scan function, scan the disk in question and attempt to repair the bad sector. But its function is extremely limited, usually only deal with simple logical sector error, if they are really physical bad sectors, it detects the speed will be very slow.The manufacture process of world level is adopted forcell phone jammer. At this point you can spend some more powerful detection software does not scan the hard disk bad sectors, such as HDDTEST. HDDTEST is an extremely compact software, I use this version only 8KB size. But it can only run in pure DOS environment, the use of the former first copy it to a bootable floppy disk, floppy disk and then be activated. HDDTEST all operations are completed in a single window interface, not too many commands and complex operation. Press the arrow keys to select the drives to be detected, and then press "Enter" key to start the test. Detection of the way by "Pause / Bnter" key to pause, press the "Esc" key will cancel the test. Middle of the window shows the detection progress. cell phone jammer has another feature of high cost performance. The following were shown the state of the software running the disk test prompted the state, the lower right corner displays information about bad sectors. As with detection only, not to repair the hard disk when it detects bad sectors on the other similar software, very fast. In addition, HDDTEST can not manually select a location starting from the hard drive detection, can only be comprehensive from start to finish scanning. Second, multi-wall sword together, even if bad sectors hard drive repair hard drive is brand new, in fact, is not flawless, no bad sectors. In fact, each more or less hard in the production process will have a certain number of bad sectors. The company will use specialized equipment to detect and record all of the bad sectors in the P-Iist (permanent defect table) for the ordinary user can not be viewed, access can not be recorded in the P-Iist of bad sectors.The fifth characteristic of cell phone jammer is the accordance with the characteristics of Chinese mobile communication. In other words, the end user's hard drive will be purchased with a certain number of bad sectors, but this part of the company in a special way to be masked, did not affect the normal use of the hard disk, so hard disk bad sectors does not like people really that terrible. In general, if the bad sectors on the hard drive is not too serious, then sent to manufacturers in addition to repair, but also some software you can try to repair it. First, the use of some basic hard drive maintenance tools, such as the hard drive manufacturer's DM software and other low-level formatting tools Iformat can repair some of the logic of hard disk damage. cell phone blocker has fully considered the detailed situation of mobile communication network in whole machine design and function setting. DM with zero-filling and low-level formatting functions, to the hard drive data is cleared, and rewrite the sector verification and identification information, identification information to fix the error and other causes of bad sectors. Re-use Iformat low-level format the hard drive can achieve the same effect.
