How to recover the lost space of the hard disk with Diskgenius

Diskgenius is a very useful partition tool, however, in addition to the computer, hard disk partition, Diskgenius function There are many, for example, to help the hard drive to find the missing partition. So how did Diskgenius do it? Let's take a look at today's use of Diskgenius to find a way to lose space on the hard drive!

Master Readme: The purchase of computer hard disk format after the capacity of 38GB, divided into C, D, e three areas, of which the main partition C capacity of 5GB, extended partition D, E split the remaining space, about 16.5GB. Today, after the computer boot all normal, but trying to "my Computer" to choose e disk, unexpectedly found e disk mysterious disappearance.

On-site situation: The current computer operating system for Windows 98, open "My Computer", only show the hard drive letter C, d,e disk display as the optical drive (originally F disk). C, D disk capacity, content is normal, the Windows 98 operating system does not work abnormal.

Primary cause: Hard disk partition is hidden or system displays information error

Hango: At present, for computer security considerations, many software has hidden hard disk partition function, in addition to specialized encryption software, common also "Windows optimization Master", "Super Magic Bunny Set" and so on. After the inquiry learned that the owner did not have a similar setting, the machine does not have such software, the basic can be excluded from the possibility of artificial hidden hard disk partitions.

In addition, is there an error in the hard drive? Check the hard drive with a disk scanner under Windows 98, and no errors are found.

Re-cause: Hard disk partition table is damaged

Hango: The hard disk partition table is located at the back of the hard disk main boot sector, saving the partition's boot flag, System flag, start and end cylinder number, sector area code, magnetic number one and other important data. If the partition table is compromised, it will cause a loss of disk and other failures.

To verify that the partitioned table is intact, run the hard disk partition software Fdisk in DOS and select the 4th "Display patition Information" To view the partition table information. The information shows that the current hard drive capacity is 38GB, the primary partition is 5GB, and there is only one logical partition in the extended partition, with a capacity of 16.5GB. The total capacity shown by the hard disk is not equal to the actual partition capacity, that is, another 16.5GB of space is not recognized and should be caused by damage to the partition table of the hard disk.

1. Before using Diskgenius, the system should be "disinfected" first. The use of computer-installed anti-virus software (the latest version of the virus) to check the system, sure enough to kill a number of viruses, hard disk partition table damage estimates are also computer viruses.

2. Boot the system into DOS with floppy disk, run the Diskgenius program on disk, then display the current hard drive information as shown in Figure 1. According to the figure, the current hard drive system is divided into three regions, the total capacity of the hard disk is 38162.2MB, but the second extended partition of the hard disk does not recognize its type, cannot be used, and appears dimmed.

3. Select Menu "tools → rebuild partition Table", then pop-up message prompts to backup the existing hard disk partition table, click "Continue" to go to the next step.

4. Pop-up Prompt box (Figure 2) prompts the user in which way to search, select Automatic mode.

5. In less than a second time, the screen prompts "partition table rebuild completed, save after". Then look at the hard drive information data (Figure 3), the gray extension partition in Figure 1 has been identified as the FAT32 partition, and the missing partition is found.

6. After the disk exit, enter the Windows 98 system, open "My Computer." At this time to see E disk has been recovered, open e disk to view the contents of the computer, the original preservation of all kinds of information intact, the program runs normally, the operation was successful.

Computer Doctor Tip: Users in the use of computer, in addition to strengthening the awareness of anti-virus, but also to strengthen the backup of important data. In addition, a proper grasp of some data repair tools to use, more conducive to self-help.
