[0048] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

[0049] Specific embodiments of the present disclosure are described hereinafter; however, it is to be understood that the disclosed embodiments are merely examples of the present disclosure, which can be practiced in various ways. Well-known and / or redundant functions and structures are not described in detail to avoid obscuring the present disclosure unnecessarily. Therefore, specific structural and functional details disclosed herein are not intended to limit the present disclosure but are merely as examples to teach a person of ordinary skill in the art to use the present disclosure in substantially any appropriate detailed structure.

[0050] The specification can use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which can refer to one or more embodiments according to the present disclosure.

[0051] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0052] As shown in the figure, the embodiments of the present application provide a processing method, comprising: Figure 1

[0053] Step S101: After the electronic device is powered on, detecting whether the target data exists in the first storage area of the electronic device, the target data can affect the electronic device to realize the first function in the first storage area;

[0054] Step S201: In the case that the target data exists in the first storage area, performing the operation of clearing the target data, so that the electronic device can at least realize the first function in the first storage area.

[0055] For example, taking the electronic device as a notebook computer, desktop computer, server, workstation and other devices as an example, when the electronic device is powered on, the device will automatically detect whether the target data exists in the first storage area. The target data is the data that can affect the electronic device to realize the first function in the first storage area. For example, the target data can affect the electronic device to initialize the first storage area, complete the startup of the device or the installation of the system, etc., or cannot make the electronic device realize the storage of other data in the first storage area, or cannot add the first storage area to the disk array to perform the storage function, etc. The specific one is not unique. When it is determined that the target data exists in the first storage area, the device will perform the clearing operation on the target data, so that the electronic device can at least realize the first function in the first storage area. The clearing operation refers to removing the target data in the first storage area, as long as the first storage area does not have the target data.

[0056] Based on the disclosure of the above embodiments, it can be known that the embodiments have the beneficial effects that the electronic device can automatically detect the first storage area in the power-on stage, determine whether there is target data, and when it is determined that there is target data, process the target data, so that the electronic device can realize the first function in the first storage area. The above process does not need human operation, and the processing process is fast and efficient, which provides convenience for users to use the electronic device.

[0057] Further, the method in the embodiments further comprises:

[0058] Step S301: Determining the first storage area based on the storage type and / or running mode of the storage area in the electronic device.

[0059] ​For example, electronic devices may have multiple storage areas, and these areas may differ in storage type, operating mode, etc., or only some storage areas may share the same storage type and / or operating mode. Storage type can include, for example, closed-system storage or open-system storage. Open-system storage includes internal storage and external storage. External storage further includes direct-attached storage, network-attached storage, network-accessed storage, and storage area network storage, or it may include whether it is a disk array storage system. The operating mode, or storage mode, can be related to the above storage types; that is, the storage mode / operating mode is determined based on the storage type. For example, if a storage area belongs to a disk array storage architecture, then its storage mode / operating mode is a disk array storage mode. Alternatively, the operating mode can be a pre-defined mode, such as an encrypted storage mode. Furthermore, the device can also determine the first storage area based on specific information about the first function. For example, the storage area involved in executing the first function can be defined as the first storage area. For instance, when the device system boots up or is installed, it involves hard disk devices such as onboard hard drives, and these hard drives can be identified as the first storage area. The device can analyze and determine the first storage area based on one or all of the storage types and operating modes of the aforementioned storage areas, combined with preset reference data. This first storage area may include multiple areas or only one; the specific number is not unique. Furthermore, the preset reference data can be user-inputted or determined by the device itself based on big data, historical data, etc. For example, the device can determine the storage type / operating mode of the storage area containing target data that has historically affected the normal execution of the first function of the electronic device, based on historical data, big data, etc., and then determine the reference data based on this storage type / operating mode. Alternatively, the device can determine the reference data based on a specific first function. For example, when implementing the first function, the device can set the reference data based on the storage type and operating mode to determine the first storage area in the electronic device.

[0060] Optionally, the first storage area in this embodiment is a hard disk in the non-disk array area of ​​the electronic device. The hard disk in the non-disk array area includes at least one of the following: onboard hard disk, external hard disk, memory, cloud disk. That is, the first storage area can be one or more of the above types of hard disks, and may also include other types of hard disks, which are not specific.

[0061] Furthermore, such as Figure 2 As shown, when detecting whether target data exists in the first storage area of ​​an electronic device, the process includes:

[0062] Step S102: reading first block area data in the first storage area, determining whether first target data in the first block area data conforms to a target specification, the target specification being a specification affecting the electronic device to implement a first function in the first storage area;

[0063] Step S103: if the first target data does not conform to the target specification, determining that the first storage area does not exist target data;

[0064] Step S104: if the first target data conforms to the target specification, reading second block area data in the first storage area, to determine whether the first storage area exists target data based on the second block area data;

[0065] Wherein, the first block area data is different from the second block area data.

[0066] For example, taking the first storage area in the embodiment as a hard disk, which can be a hard disk without a non-disk array area. The first block area in the first storage area can be a Superblock area, a block area where 16 bytes (offset 0x00-0x0f) of data are located. The device can first read the data in the first block area, i.e. the first block area data, to determine the first target data. The first target data in the embodiment includes a "Magic Number" (a magic number that can be used to mark the format of a file or a protocol, and many files have a magic number mark to indicate the format of the file) and a "Major Version" (the main version of the above-mentioned protocol), and the device determines whether the first target data conforms to the target specification by analyzing the first target data. The target specification in the embodiment is a software raid specification, i.e. a software disk array specification, which affects the electronic device to implement a first function in the first storage area, such as affecting the electronic device to initialize the first storage area, thereby completing the startup of the electronic device or the updating, installation, etc. of the system. When the device determines that the first target data does not conform to the target specification based on the analysis and judgment result, it can be determined that the first storage area does not exist target data, and if the device determines that the first target data conforms to the target specification based on the analysis and judgment result, it will read the second block area data in the first storage area, analyze and judge the data in the second block area, and then determine whether the first storage area exists target data.

[0067] Further, as shown in Figure 3 determining whether the first storage area exists target data based on the second block area data includes:

[0068] Step S105: reading second target data in the second block area data, determining whether the second target data conforms to the target specification;

[0069] Step S106: if the second target data conforms to the target specification, determining that the first storage area exists target data;

[0070] Step S107: If at least one of the second target data does not conform to the target specification, it is determined that the first storage area does not have the target data.

[0071] Continuing with the above embodiment, when the device reads the data of the second block area, it can read the data of the Per-Array Identification & Configuration area (offset 0x10-0x63) in the hard disk, and determine the second target data through the data of the block area. The second target data in this embodiment includes "UUID for the Array", "Name for the Array", "Creation Time", "RAID Level of the Array", "layout of array", and the like. The device determines whether the second target data conforms to the target specification, i.e., the software disk array specification, by analyzing the second target data. If all the second target data conforms to the target specification, it can be directly determined that the first storage area has the target data. If at least one of the second target data does not conform to the target specification, the device can directly determine that the first storage area does not have the target data. For example, if the data information of "UUID for the Array" does not conform to the target specification, even if the rest of the second target data conforms to the target specification, the device will determine that the first storage area does not have the target data. Only when all the first target data and the second target data conform to the target specification, it can be determined that the first storage area has the target data.

[0072] Further, in the case where the first storage area has the target data, the operation of clearing the target data is performed, including:

[0073] Step S202: In the case where the first storage area has the target data, directly performing the operation of clearing the target data; or

[0074] In the case where the first storage area has the target data, outputting the first prompt information representing clearing the target data, and directly performing the operation of clearing the target data; or

[0075] In the case where the first storage area has the target data, outputting the second prompt information of clearing the target data, and performing the operation of clearing the target data in response to obtaining the input information representing the clearing instruction.

[0076] For example, in an embodiment, when the target data exists in the first storage area, the device can directly perform the operation of clearing the target data, or can perform the operation of clearing the target data only when it is determined that the execution condition is met. The execution condition can be related to implementing the first function, including receiving an instruction for implementing the first function, for example, can be that the electronic device is powered on and obtains an instruction to install an operating system in the first storage area, etc.

[0077] Alternatively, in another embodiment, when the target data exists in the first storage area, the first prompt information representing clearing the target data can be output, and the operation of clearing the target data is directly performed. The operation of clearing the target data can also be performed only when it is determined that the execution condition is met. The specific content of the execution condition is the same as above. The first prompt information can specifically represent what kind of data the device clears, that is, the data that affects the electronic device to implement the first function in the first storage area, such as the data that affects the installation of an operating system in the first storage area. The device informs the user that it will delete the target data through the output of the first prompt information, so as to ensure that the electronic device can successfully perform the first function, that is, the user is informed that the device has found data that will affect the performance of the first function, and will be processed without user intervention.

[0078] Alternatively, in another embodiment, when the target data exists in the first storage area, the device can output the second prompt information to ask the user whether to clear the target data, that is, in this embodiment, the device does not directly clear the target data, but asks the user whether to clear, and then the device responds based on the input information input by the user, and then clears the target data. Alternatively, the second prompt information can be output to ask the user, but if no user feedback is received within a preset time period, the device can directly clear the target data.

[0079] Further, the operation of clearing the target data includes:

[0080] Step S203: writing data in the first storage area to cover the target data;

[0081] Among them, writing data in the first storage area includes writing all-zero data in the head and tail of the first storage area.

[0082] Specifically, when the device performs the operation of clearing the target data, it can choose to write data in the first storage area to cover the target data, thereby achieving the effect of clearing the target data in the first storage area. The data written in the first storage area includes all-zero data written in the head and tail of the first storage area, or other data can be written to cover the target data. That is, as long as data is written in the first storage area to cover the target data, the specific data written is indefinite.

[0083] Optionally, when performing the operation of clearing the target data, the target data in the first storage area can also be directly erased or eliminated.

[0084] Optionally, when performing the operation of clearing the target data, the operation can further include:

[0085] Step S204: Migrating the target data to a second storage area, the second storage area does not affect the electronic device to implement the first function in the first storage area when the target data is stored in the second storage area.

[0086] For example, the target data in the first storage area is migrated as a whole, so that there is no target data in the first storage area, thereby realizing the clearing operation. The specific migration area can be selected as a second storage area, which needs to be a storage area that does not affect the electronic device to implement the first function in the first storage area even if the target data is stored in the second storage area. The second storage area can be an external storage disk, or a storage disk fixedly arranged in the electronic device, or a board-mounted storage disk, and the specific one is not unique.

[0087] In addition, optionally, when performing the clearing operation, the device can first migrate the target data, and then perform the clearing operation. For example, the device first migrates the target data to the second storage area, and then performs the operation of erasing or eliminating the target data, or writes data to cover the target data in the second storage area, etc.

[0088] Further, in actual application, as shown in Figure 4 , a hard disk checking module can be added in the UEFI of the electronic device, and the checking module performs the checking and clearing of the target data. Specifically, in the UEFI post process, the checking module automatically checks the non-Raid storage device hard disk in the system. If it is detected that there is target data on these hard disks, the target data can be directly cleared, or a prompt can be popped up for clearing, or a prompt can be popped up and the user is asked whether to clear the target data, and the user agrees to clear the target data. When clearing, the checking module can write all-zero data at the head and tail of the hard disk to cover the target data, realize clearing, directly erase the target data, or migrate the target data to other storage areas, or perform the clearing operation such as erasing or writing data to cover after migration. When the clearing of the target data is completed, the assembly operation of the operating system (os) can be started, and of course the specific first function is not unique, and other function operations can also be implemented.
