Hard disk partitioning is easy and simple, isn't it. But the best and best hard disk partitions are not for everyone. Especially for novices, master the basic principles of hard disk partitioning, which can be more convenient in subsequent use, and will not regret the original partitioning scheme when an application cannot be implemented.
Principle 1: FAT32 is most suitable for C drive
Reason: C drive generally uses the operating system to install, usually has two disk file system formats, FAT32 and NTFS. I feel that it is more convenient to use FAT32. Because the operating system is often abnormal or infected by a virus Trojan, we often need to use the boot tool disk to fix it. And many boot tool disks are evolved from the Win98 boot disk. In most cases, the NTFS partition cannot be recognized, so the C drive cannot be operated. I have encountered it. In the DOS, the D drive is mistaken for the C drive and rushed to format it. The painful experience of losing data collected over the years.
Principle 2: C drive should not be too big
Reason: The C drive is a system drive. The hard drive reads and writes more. The chances of errors and disk fragmentation are also high. Scanning disks and defragmentation are daily tasks, and the time between these two tasks is closely related to the capacity of the disk. The capacity of the C drive is too large, which often makes these two jobs extremely slow, which affects the work efficiency. It is recommended that the capacity of the C drive is 10GB~20GB.
Principle 3: Try to use NTFS partitions in addition to the C drive
Reason: The NTFS file system is a file system based on security and reliability. It is far superior to FAT32 except for compatibility. It not only supports partitions up to 2TB in size, but also supports compression of partitions, folders and files for more efficient management of disk space. For LAN users, access permissions can be set for shared resources, folders, and files on NTFS partitions, and security is much higher than FAT32. Therefore, in addition to using FAT32 for compatibility in the main system partition, it is more appropriate to use NTFS for other partitions.
Principle 4: The benefits of dual systems and even many systems
Reason: Trojans, viruses, slow systems, inability to access the Internet, and system failures are commonplace. Once this happens, reloading and anti-virus can take a lot of time and often delay work. Some stubborn bootloaders of Trojans and viruses can't even be removed from the original system. At this time, if there is a backup system, things will be much simpler, boot to another system, you can calmly kill, remove Trojans, repair another system, and even use the image to restore the original system. Even if you don't do it, you can use another system to start work, and you won't delay things because of computer problems.
Therefore, the advantages of dual system and even more systems are more. In addition to the C drive, it is necessary to reserve one or two spare system partitions in the partition. The backup system partition can also be used to install some software programs at the same time. The capacity is about 20GB. .
Principle 5: Separation of systems, procedures, and data
Reason: Windows has a very bad habit of putting some personal data such as "My Documents" into the system partition by default. In this way, once the system disk is formatted to completely kill viruses and Trojans, and there is no backup data, data security is very problematic.
The correct way is to install the programs that need to copy files and write data in the system folder and registry to the system partition; for those programs that can be installed green, only the files in the installation folder can be run to the program. In the partition; various texts, forms, documents, etc. do not contain executable files themselves, and other programs are required to open the data and are placed in the data partition. In this way, even if the system is flawed, when you have to reinstall it, the available programs and materials are not lacking, and you can resume work quickly without having to recover from re-finding the program.
Principle 6: Retain at least one giant partition
Reasons: It should be acknowledged that as hard drive capacity grows, the size of files and programs is growing. In the past, a compressed movie was only a few hundred MB, and today's HDTV is close to 20 GB; the previous game was only a few tens of megabytes, and the bigger one was only a few hundred megabytes. Now a game is a few hundred pounds. If you are partitioning according to the average principle, when you want to save two HDTV movies, the storage of these giant files will be in trouble. Therefore, for a large number of hard drives, it is very necessary to separate a partition with a capacity of more than 100 GB for the storage of huge files.
Principle 7: Give BT or eMule a partition at the end of the disk
Reasons: Bit-to-point transmission software such as BT and eMule are frequently used to read and write to the disk. Long-term use may cause certain damage to the hard disk, and even cause bad sectors in severe cases. For bad sectors of the disk, we usually use the repair method to solve it, but once it can't be repaired, it should be shielded with software like PQMaigc. At this point, you'll find it much easier to resize and mask bad sectors at the end of the disk. So it is more convenient to give BT or eMule a partition at the end of the disk.
Hard disk partition repair full Raiders
Due to partition failure, it is very likely that you will not be able to enter the familiar Windows interface when you turn on the computer, or even the system boot disk will not be able to recognize the hard disk. At this time, everyone will be helpless.
If you rush to re-partition the hard drive, you can solve the problem completely, but all the important information in the hard drive will be wiped out. If you are unfortunate enough to encounter a hard disk partition failure, don't rush to re-partition, try the method described below, maybe there will be an unexpected surprise.
Why does the partition table fail?
After the partition table is destroyed, "Non-System disk or disk error, replace disk and press a key to reboot", "Error Loading Operating System", "Dos Loading Dos" often appear when starting the system. Boot record error) or "No ROM Basic, System Halted" (can not enter ROM Basic, the system stops responding) and other prompts. So how does the partition table failure happen?
1. Virus causes failure
One of the most typical failures is the virus causing partition table corruption. For example, a typical variant of the CIH virus, in addition to attacking the BIOS of the motherboard, also destroys the partition table, and there are many boot sector viruses that also destroy the partition table.
2. Environmental problems lead to
Today's Windows 2000/XP supports the NTFS file format, and the default is to use this file format to install the system. If the hard disk is partitioned or the NTFS partition is accidentally powered off or crashed, it is likely to cause The partition table is corrupt. Moreover, there are certain risks when adjusting the hard disk partition capacity and converting the partition format through third-party partitioning software such as PQMagic. If the computer is dead or powered off, the hard disk partition table may be faulty, and even the hard disk may be lost. All the data.
3. Improper operation
If multiple operating systems are installed on one hard disk at the same time, it may cause partition table failure when uninstalling. For example, on a computer with both Windows 2000 and Windows 98 installed, directly deleting the Windows 2000 kernel will result in the partition table. error. In addition, if you delete the partition without deleting the extended partition first, but directly delete the primary partition, there will be a failure to correctly read the partition label.
Partition table failure emergency strategy
1. Killing the virus
If the partition table is faulty due to the boot sector virus, you can use the boot floppy disk provided by the KV3000, Rising, Jinshan and other anti-virus software to start the computer, and then perform virus killing on the system in the DOS environment. For example, use the KV3000 boot disk to start the computer and enter the "KV3000/K" command to scan the virus. If there is a virus in the boot area, the program will automatically check and kill. It is recommended to perform a complete scan of the entire system to find hidden. virus. In general, the normal use of the computer can be resumed after the residual virus in the boot area is cleared.
Tip: Be sure to turn off the write protection of the floppy disk before booting the computer with a floppy disk. Otherwise, it may cause the virus to infect the floppy disk.
2. Repair with Fdisk command
Fdisk is not only a partitioning program, it also has a very convenient function of restoring the main boot sector, and it only modifies the main boot sector and does not write to other sectors, so for those who are still using Windows 9x This is undoubtedly a very ideal partition table repair tool. When repairing the main boot area through Fdisk, first boot the system with the Windows 98 boot disk, and enter the "Fdisk /mbr" command at the prompt to overwrite the main boot area record.
Tip: The "Fdisk /mbr" command only restores the primary partition table and does not rebuild it. Therefore, it is only applicable to the primary boot sector record being damaged by the boot sector virus or the master boot record code is lost, but the primary partition table is not corrupted. Use of the situation. And this command does not apply to clear all boot viruses, so you need to pay attention when using them.
3. Fix the boot record with Fixmbr
In Windows 2000/XP, we generally use some enhanced commands integrated by the Recovery Console. For example, Fixmbr is used to repair and replace the master boot record of the specified drive, Fixboot is used to fix the boot sector of the known drive, and Diskpart can be added. Or delete the partition in the hard disk, Expand can extract the missing files from the specified CAB source file, Listsvc can create a service list and display the current startup state of the service, Disable and Enable are used to prohibit and allow a service or Hardware devices, etc., and enter the "help" command to see all the control commands and a detailed explanation of the commands.
