How to recover a Windows "vanishing" disk partition

window| Recovery

Hard disk partition failures often occur, and if the missing partition is storing very important information, it is often a matter of impatience, even to pay a great deal of money to find a professional data recovery technician to recover.

In my account, the loss of hard disk partitions accounts for more than 20% of the data recovery, most of which are caused by viruses and improper operations. Some performance is only to find C partitions, and some even the performance of all partitions are not visible, the direct cause of the partition loss is mostly due to hard disk partition table error or partition table was cleared and caused.

The hard disk partition table is an important part of the hard disk main boot sector, which plays a key role in the system's self lift. Once the partition table is compromised, the hard disk partition information will be corrupted, resulting in the loss of the hard disk partition.

Feel this hard disk partition table is also very fragile, in this case, if your data is very important and no basic knowledge of data repair, we recommend that ordinary users do not destroy the original data and do not unauthorized use of some unprofessional software to repair, preferably to have data repair experience of people to repair, Otherwise it will be more troublesome to fix it later.

However, as long as there is a little experience, it is not difficult to repair. For example, the use of a software named Diskgenius can automatically repair some simple faults. The operation is very simple, just put the software on your DOS boot disk, and then run the software, and finally in the software main interface by pressing F10 can be automatically repaired. In addition, if friends have some actual combat experience, then can also use NDD, Winhex and other software for manual repair, often can be "Handers".

There are many ways to fix a hard disk partition table, such as using the FIXMBR command in the Windows XP Recovery Console, or you can boot the system with a Windows 98 CD-ROM, and then use the FDISK/MBR command to fix it. It should be explained that it is not possible to solve the problem completely by one method, and you can try a variety of methods until the repair is good. According to the partition table's destruction program, also can not be able to repair the hard disk partition table absolutely.

Yes, but the best way to do this is to back up your hard disk partition table information before the partition is lost. For example, use the disk Probe tool with the Windows XP CD Dskprobe to back up. The tool can be found in the System CD \support\tools\support.cab installation package.

In the Dskprobe main interface "drives" menu, click "Logical Volume", and then in the "Logical volumes" list, double-click a section to be backed up (Figure 1), then activate the "Set Active" button, click on, then click "OK ”。 Then click "Read" on the "Sectors" menu and click "Read" In the pop-up menu, and then click "File→save as" to back it up.

Figure 1

When a partition loss occurs, just activate the partition you want to restore in Figure 1, and then cancel the Read only check box, click Open File on the File menu, then locate the previously backed up partition table file and click Sectors→write. Finally, click "Write it" in the pop-up window to restore the repair (Figure 2).

Sometimes the partition table is not compromised, for example, if a friend enters a DOS or logs on to a Windows 9X system, it will find that a partition is missing, but not the partition is lost, because NTFS format partitions are not recognized in DOS and Windows 9X systems, but can be resolved using the NTFS for DOS program.

Yes, there are other situations, such as Windows and Linux installed by some users, but they cannot exchange visits to their partitions under Windows and Linux because they do not recognize each other's disk format. If you want to access the partition where Linux is located directly under Windows, you can use a software named EXPLORE2FS (download address: http://download.enet.com.cn/html/030282000080601.html); If you want to access Windows partition information under Linux, you can do this directly using the Linux mount command plus configuration parameters.

In addition, some software also has the ability to hide partitions, such as Pqmagic has this function, just select the partition to hide (but do not hide the system partition, otherwise will not be able to enter the system), and then execute the "advanced→hide Partition" command and in the pop-up window click " OK "confirmation can be. In fact it is the DOS partition into a non-DOS partition, the implementation of the "Advanced→unhide Partition" command, and finally click "OK" to confirm.

There are many reasons why partitions are missing, so it is best to back up the hard disk partitions before a failure. In addition, in the operation of the computer also to operate correctly, do not illegally shutdown, there is to use a key to restore software, ghost software and disk partition software, if not correctly used, it is also easy to cause partition loss. Do not worry too much when a partition is missing, and then try to fix it after figuring out why.
