Abstract

The invention discloses a method for detecting capacity of a storage device. The method includes: writing different source data into multiple target addresses of the storage device, wherein, the source data written in the target addresses are mutually different; reading data from every target address of the storage device; confirming whether the data read from the target addresses is identical to the data written in the corresponding target addresses or not via comparing; and judging the capacity of the storage device to be not true if the read data are not identical to the written-in data. In the method for detecting the capacity of the storage device, not every address needs to be read, written and detected, spaced addresses are selected to be read, written and detected, so that detecting speed is increased, and detecting accuracy is not obviously lowered.

Description

【Technical field】 [0001] The invention relates to the field of storage, in particular to a method for detecting the capacity of a storage device. 【Background technique】 [0002] At present, flash memory (Flash Memory, referred to as Flash) is widely used, and there are many storage devices or products manufactured with flash memory. The cost proportion of flash memory in these storage devices or products is very large, generally can reach 70%-80%, even can reach more than 90%. Taking TF card (Trans-FLash Card, also known as Micro Secure Digital Memory Card) as an example, the current price of 8GB is about 25-40 yuan, of which the price of 8GB Flash is about 22-28 yuan, accounting for 1. More than 80%. Therefore, how to control the price of Flash has become the key profit point for Flash storage device manufacturers, and even the basis for the survival of manufacturers. [0003] When using a flash memory device, users usually do not pay attention to how much capacity they ...
