The hard disk to be repaired is checked whether to be normally identified, that is, the Partition type of the hard disk and each Partition divided on the hard disk can be normally identified, wherein the Partition type may be an MBR (Master Boot Record) type or a GPT (global Unique Identifier) Partition Table (raid) type.
Step S102, when detecting that the hard disk to be repaired can be normally identified, recording the partition existing in the hard disk.
Specifically, the hard disk to be repaired can be normally identified, and the partitioned partitions existing on the hard disk can be identified. For example, after loading the hard disk, it is displayed that the C partition and the D partition exist in the hard disk, and at this time, the existing partitions C partition and D partition need to be recorded.
In addition, if it is detected that the hard disk to be repaired cannot be normally identified, that is, after the hard disk is loaded, a loading error is prompted, at this time, the partition type of the hard disk may be set to be the MBR type, the boot sector of the hard disk is repaired, and then step S103 is executed.
Step S103, scanning sectors in the hard disk, and determining repairable partitions according to the scanning result, wherein the repairable partitions comprise the existing partitions.
Specifically, various sectors of the hard disk are scanned, thereby obtaining a repairable partition. Comparing the repairable partitions with the existing partitions recorded in step S102, it can be determined which repairable partitions are the corresponding existing partitions.
In one embodiment, the step S103 of scanning the partitions in the hard disk includes:
(a) and determining the identification of the sector and judging the partition attribute of the sector.
The partition attributes include NTFS (New Technology File System) partition, FAT (File Allocation Table) partition, and Extended File Allocation Table (Extended FAT) partition, where the FAT partition includes types of FAT12, FAT16, FAT32, and the like.
Specifically, the determining the partition attribute of the sector includes: judging whether the sector belongs to the NTFS partition or not; if not, judging whether the sector belongs to the FAT partition or not; if not, judging whether the sector belongs to the ExFAT partition or not. That is, whether a sector belongs to NTFS partition, FAT partition, and ExFAT partition is sequentially determined, and the specific determination sequence is not limited herein.
(b) And determining the range of the scanned partition according to the identification and the partition attribute of the sector.
The range of the partition includes a plurality of parameters, which may specifically include a size of each partition and an identifier of a starting sector of each partition.
Fig. 2 is a flowchart illustrating a sector scanning process in the partition repairing method according to an embodiment of the present invention. In an embodiment, the scanning the partition in the hard disk specifically includes:
step S201, determine whether the current sector belongs to the NTFS partition.
If yes, sequentially executing step S202 and step S207; if not, go to step S203.
Step S202, determining that the partition to be repaired of the NTFS exists, and recording the initial sector and the partition size of the partition to be repaired of the NTFS.
Specifically, the starting sector and size of the partition to be repaired by the NTFS may be determined by the NTFS primary sector.
Step S203, determine whether the current sector belongs to the FAT partition.
If yes, sequentially executing step S204 and step S207; if not, go to step S205.
Step S204, determining that the FAT partition to be repaired exists, and recording the initial sector and the partition size of the FAT partition to be repaired.
Step S205, determine whether the current sector belongs to the ExFAT partition.
If yes, executing step S206 and step S207 in sequence; if not, step S207 is directly performed.
Step S206, determining that the ExFAT partition to be repaired exists, and recording the initial sector and the partition size of the ExFAT partition to be repaired.
Step S207, reading the sector identifier.
Step S208, determine whether the current sector is the last sector.
Specifically, it is determined whether the sector corresponding to the sector id is the last sector through the sector id read in step S207. If yes, the execution process is ended; if not, step S209 and step S201 are executed in sequence.
Step S209 updates the sector identification.
In one embodiment, the sector identification is incremented by one and recorded, and then the next sector is scanned, step S201.
Therefore, through the sector scanning process, the size of each partition and the identifier of the start sector of each partition can be obtained, so as to obtain the range of each scanned partition.
Further, in order to improve the user experience, expand the selectable performance, and further meet the diversified requirements of the user, in step S103, determining the repairable partition according to the scanning result includes: judging whether the range of each scanned partition has partition overlapping; if so, a plurality of repairable partition combinations are determined based on the partition overlap.
Specifically, for example, the range of the partition C obtained by scanning is sector 0 to sector 30, the range of the partition D is sector 31 to sector 90, and the range of the partition E is sector 61 to sector 90, at this time, it may be determined that the partition D and the partition E overlap, and at this time, it may be determined that the partition C and the partition D are combined as follows (1); (2) partition C, partition D, and partition E. Therefore, the partition repairing method provided by the embodiment of the invention can automatically identify the unreasonable situation caused by partition range collision, and provide a plurality of choices for users.
It should be noted that the specific numerical values in the above embodiments are only exemplary and do not limit the scope of the present invention.
Step S104, displaying a selection interface of the partition to be repaired, wherein the selection interface comprises all recoverable partitions, and the existing partition in the hard disk is marked as a selected state.
Specifically, after the repairable partition is determined, the user may be allowed to select the partition, so that the partition selected by the user is repaired. In one embodiment, a plurality of the above-described repairable partition combinations are displayed on a selection interface. In order to prevent the existing partition from being damaged due to the fact that the user selects the partition in a missing mode or in a wrong mode in the subsequent process, the existing partition in the hard disk is marked to be in a selected state.
Step S105, receiving the partition to be repaired selected by the user, and marking the partition to be repaired as a selected state.
Specifically, the user selects a partition to be repaired from the partition combination as the partition to be repaired. And marking the partition to be repaired so as to facilitate the subsequent repair processing.
And step S106, repairing the partition marked as the selected state.
Specifically, a partition table is created or updated for the partitions marked as selected (including the existing partitions and the partitions to be repaired selected by the user), and parameters of each partition marked as selected, such as partition size, end-of-sector mark, start sector, hidden sector and other items to be repaired, are modified. The specific repair process can be performed by referring to the existing scheme in the prior art.
In addition, if it is determined in step (a) above that there is an ExFAT partition to be repaired, the corresponding uppercase character file needs to be updated or created in step S106.
In the embodiment of the invention, the partition repairing method comprises the steps of detecting whether a hard disk to be repaired can be normally identified; if so, recording the existing partitions in the hard disk, scanning sectors in the hard disk, and determining repairable partitions according to the scanning result, wherein the repairable partitions comprise the existing partitions; displaying a selection interface of a partition to be repaired, wherein the selection interface comprises all recoverable partitions, and the existing partition in the hard disk is marked as a selected state; receiving a partition to be repaired selected by a user, and marking the partition to be repaired as a selected state; the partition marked as the selected state is repaired.
