The invention discloses a non-aligned data error processing method, a control component and a storage device. The method comprises the following steps: in response to a non-aligned write storage command, acquiring to-be-written data based on the non-aligned write storage command; reading the data to be merged from the NAND, and verifying whether the data to be merged is correct; if so, processing the merged data of the to-be-merged data and the to-be-written data by using a first scrambling mode; and if the error exists, processing the combined data of the to-be-combined data and the to-be-written data by using a second scrambling mode different from the first scrambling mode, and marking the sector for reading the error data. By adopting the technical scheme of the invention, the found non-aligned data error is hidden for the address which is not read by the host, and the processing of the non-aligned write command can be normally completed even if the data reading error occurs when the non-aligned write com
