Embodiment 1

[0070] Embodiment 1 provides a flow chart of a specially formatted mobile storage device. attached figure 1 It records the formatting process for special formatting of mobile storage devices.

[0071] 1) Determine whether the current special formatting method is only redirection (does not encrypt sector data);

[0072] 2) If it is only a redirection operation, go to step 3); otherwise, judge whether the current environment is a safe environment, if it is a non-safe environment, it will prompt that special formatting cannot be performed, go to step 10), otherwise go to step 3);

[0073] 3) Construct MBR and update MBR data;

[0074] 4) If it is only a redirection operation, format the data of each partition, and then perform a redirection operation on the MBR and each partition DBR to ensure that the mobile storage device can be used normally in a safe environment, and cannot be used in a non-safe environment, and the partition cannot Call the system formatting tool to forma...

Embodiment 2

[0097] Embodiment 2 provides an alternative method for specially formatting the mobile storage device. attached image 3 It is another flow chart for special formatting of mobile storage devices. The method includes:

[0098] 1) Determine whether the current special formatting method is only redirection (does not encrypt sector data);

[0099] 2) If it is only a redirection operation, go to step 3); otherwise, judge whether the current environment is a safe environment, if it is a non-safe environment, it will prompt that special formatting cannot be performed, go to step 10), otherwise go to step 3);

[0100] 3) Construct MBR and update MBR data;

[0101] 4) Format the mobile storage device;

[0102] 5) Determine whether only the redirection operation is performed, if the redirection operation is performed on the MBR and each partition DBR, go to step 10); otherwise, go to step 6);

[0103] 6) Set the encryption status information of the mobile storage device, which will...

Embodiment 3

[0113] Embodiment 3 provides an apparatus for special formatting of a mobile storage device. attached Figure 4 It is a specially formatted device structure diagram of a mobile storage device. The mobile storage device includes the first system data and the second system data. The device includes:

[0114] Redirection judging unit: judging whether to perform only redirection operation (do not perform encryption operation on sector data);

[0115] A system data construction unit: constructing and updating the master boot record MBR of the mobile storage device;

[0116] Prompt unit: Prompt whether special formatting can be performed;

[0117] Safety environment judging unit: judging whether the current environment is a safe environment;

[0118] The first formatting unit: formatting each partition data of the mobile storage device;

[0119] The second formatting unit: format each partition data of the mobile storage device, and after the formatting operation is completed, t...

Abstract

The invention discloses a special formatting method and a special formatting device for mobile storage equipment, and aims to solve the problem that data of mobile storage equipment leak in an unsafe environment. The mobile storage equipment comprises first system data and second system data. The special formatting method for the mobile storage equipment comprises the following steps of judging whether redirection operation is performed only or not, judging whether the current environment is a safe environment or not if the redirection operation is not performed only, prompting that special formatting cannot be carried out if the current environment is not safe, and then quitting; constructing and updating the first system data of the mobile storage equipment; judging whether the redirection operation is performed only or not, formatting the mobile storage equipment if the redirection operation is performed only, then performing redirection operation on the first system data and the second system data of the mobile storage equipment, and quitting; performing redirection operation on the first system data if the redirection operation is not performed only, setting an encryption completion status, setting an encryption key, formatting data of various partitions of the mobile storage equipment, and performing redirection operation on the second system data of the various partitions.

Description

technical field [0001] The invention relates to a storage management technology, in particular to a mobile storage medium management method and device. Background technique [0002] Mobile storage media are small in size, large in capacity, and easy to carry, and are quickly popularized in the process of information storage and exchange. However, because the mobile storage device does not provide any protection for its stored data, once the device is lost or held by an illegal visitor, it will cause data leakage and threaten the security of information. Therefore, how to solve data storage and information exchange security as soon as possible has gradually become the focus of concern of individuals, governments, enterprises and institutions. [0003] At present, security technologies for mobile storage devices mainly include the following aspects: [0004] 1) Authentication technology. At present, it mainly includes password authentication, smart card technology, and biom...
