Abstract
The present invention discloses a method and device for reading a memory card comprising a primary partition and at least one backup partition. The method comprises the following steps that: after writing a first file into the primary partition of the memory card, a read/write device writes the first file into the at least one back partition; and when reading a second file from the memory card, the read/write device reads the second file from the at least one backup partition or from the primary partition if an error occurs in the reading of the second file from the backup partition. The method and device provided herein address the problems existing in the prior art that an embedded system is unstable because of the low error tolerance of a memory card.
