Abstract:
A method, apparatus and device for preventing data loss and system damage of a USB flash disk. The method comprises: adding, to a main control chip of a USB flash disk, a one time programmable (OTP) storage space (S101, S501); storing running code and original algorithm management table data in the one time programmable (OTP) storage space (S102, S502); and when a Boot Loader fails to normally load the running code or original algorithm management table data, reading the stored running code data from the one time programmable (OTP) storage space and recovering the running code data according to the read running code data, and reading the stored original algorithm management table data from the one time programmable (OTP) storage space and recovering the original algorithm management table data according to the read original algorithm management table data (S103, S503). By the above-mentioned means, the USB flash disk can be protected against situations in which original data of a user is lost or the USB flash disk cannot run due to system damage.
