Hard disk repair Topics (Lecture)
Hard basic knowledge
Hard drive failure in the study of the specific approach, we need to first understand some of the basics of hard drive related.
MBR master boot record area
Is a magnetic media hard drive external storage devices, each disc in its surface to the shaft axis, to a certain number of magnetic density interval was divided into concentric tracks (Track), each track has been divided into several sectors (Sector), a sector of data stored on the hard disk. The first disk sector (sector 1 0 0) is reserved to the master boot sector. Within the master boot sector has two main elements: the master boot record (the operating system boots) and hard disk partition table. When the computer starts to read the sector data, and to determine its legality (the last two bytes of sector or whether 55AA AA55), such as the implementation of the legal sector is the first jump instruction. So the hard disk master boot record viruses often become the object of attack, and thus has been tampered with or destroyed.
-Issue
Many times there will be some of our computer problems seem incredible, in fact, just frightens ourselves, that is, Bobo thread, Dodo jumper little effort. Common cold sweat you out of hard disk space does not bootstrap There are two main issues:
System does not recognize the hard drive:
The most common type of failure, when prompted to complete the following POST error message:
HDD controller failure Press F1 to Resume
The E text means "hard disk can not start", sometimes with CMOS in the automatic monitoring function can not find the hard drive's existence. When the above information, you should first check with the focus on the hard disk of the power cord, interface cable for damage, loose, bad, reverse and so, in addition to the common reason is that the master-slave jumpers on the hard drive is set wrong .
Inspection, troubleshooting:
Re-plug the hard drive power cable, data cable, or plug the data cable to change IDE port to replace the other tests.
CMOS error caused the failure:
Power displays the following information:
Drive not ready error Insert Boot Diskette in A
Press any key when ready ...
The above error, mostly due to CMOS or CMOS settings wrong CMOS power supply shortage caused by loss of information caused.
CMOS settings right or not directly affect the normal use of the hard disk. When the hard disk type error, read and write errors often occur, and sometimes simply can not boot the system. Such as the CMOS drive type is less than the actual hard disk capacity, the hard drive behind the sector will not be able to read and write.
Inspection, troubleshooting:
Reset or reset the CMOS discharge data.
If not the above two reasons, then most of your hard drive is "hanging", and would like to put it scrapped the easy way out, drive it for a new block. If the hard disk has important data or you want to have strong hands, please Follow me.

Hardware Troubleshooting
Hard failure is physical failure is due to the drive's mechanical parts or electronic components caused by physical damage. Hard drive failure is a common bad sectors, the performance of one of the most serious special case of zero track damage.
Hard disk damage repair:
The logical bad sectors and bad sectors hard disk physical bad sectors into two, the former is a logical failure, usually caused by improper operation or use software, accessible software repair; latter physical failures that produced a track on your hard drive physical damage, can only change or hide the hard drive sector to resolve.
1, logical bad repair
For the logical bad sectors, Windows comes with "ScanDisk (Scandisk)" is the most simple and common means of settlement. If the hard disk has bad sectors, we can run in the Windows system environment "ScanDisk", it will do a full hard disk scan, and the possible bad clusters to do automatic correction.
In addition to Scandisk, there are many excellent third-party repair tools such as Norton Disk Doctor NDD (Norton Disk Doctor) and repair the hard drive PCTOOLS logical bad sectors and so is a good helper.
NDD: choosing the partition to be processed and then select the "Automatically fix errors", click on "Diagnostics" button. After a series of "partition table", "Boot Record", "file structure" and "directory structure" diagnosis and "surface test" later, it automatically gives a statistical report on the diagnosis, so that your hard drive's "health "situation with confidence.
In addition, the hard disk drive manufacturers introduced for the series of factory-specific DiskManager program, more familiar with the circuit structure of the hard disk itself, and curing procedures, and easier to repair disk errors. Therefore suggest that you have to download a copy of your vendor-specific Disk Manager program, more convenient to fix your own hard drive.
2, the physical isolation of bad sectors
Appear on a hard disk can not repair physical bad clusters or bad sectors, we can use some software to separate the disk into a zone and hidden, so that the head is no longer read it, so to some extent can make your hard drive extended service life. Needs to be stressed is that there are bad sectors hard disk to use, we must always do the backup work, because there was a bad hard drive, the more bad sectors will come one after another, you face gone database tears.
The easiest fix this error is a Windows system tool that comes with Fdisk. If there are physical bad hard disk, described earlier by the Scandisk and NDD we can roughly estimate the location of bad sectors, then use Fdisk partition set aside for these bad sectors separately logical partition, all partitions containing the steps to complete before the delete the logical partition bad sectors, and the remaining is not a good plate of bad sectors.
With PartitionMagic, DiskManager other disk software can accomplish this task. Partitioning software such as PartitionMagic, first select the hard disk partition, use the "Operation" menu "check for errors" command scans the disk, calculate the bad clusters on the hard disk location, then in the "Operation" menu, select "Advanced / bad sector re-test "; the bad cluster is divided into several areas where the hard drive, then use the" Operation "menu, select" Advanced / hidden partition "to hidden partition where the bad clusters. This can have serious bad sectors hard disk to ensure the normal use, and remove the system frequently to read and write bad sectors to extend the area of bad sectors.

Need to pay special attention to the repaired hard disk do not re-use the Fdisk under DOS partitioning tools such as its re-partition, so its hard to change the start and the fan, air charge of our efforts.
Zero track damage repair:
In hard use, when the zero track damage found in the general case also sentenced to death hard, difficult to repair. But for hard disk 0 sector damage, although more difficult, but not hopeless. Rational use of some disk software to block out the damaged sector 0, and replace it with a sector are "revived" the possibility of such software and other Pctools and Norton NU.
NU 8.0 tools into the package directory, run the main program NORTON.EXE, then select "Disk Editor Diskedit", after a successful run election, "Object Object", select "partition table" will be the starting sector of the hard disk from the surface 0 column 1 column sector to sector 1 1 0 surface. Also need to say is, change the value according to specific circumstances. Finally, save and exit restart the computer, use the Format command to format the hard disk can be properly used.

It's quite easy to get a 64-bit system these days. Most every modern computer, application, and operating system is designed around the 64-bit architecture. Due to both availability and price, your average 
The obvious benefit to having more memory in your system is that it lets you hold more data in a place that the CPU can access quickly. Your RAM is a much faster resource than the virtual memory that your hard drive uses, in part because of the way the data is stored, on chips, and because of the speed of the interfaces. You may notice when your system is low on available RAM, it begins to chug and hang; that's your hard drive trying to keep up with the speedy demands of the CPU.
