| It reads the requested number of blocks from the device. | |
| All the blocks are read, or an error is returned. | |
| @param This Indicates a pointer to the calling context. | |
| @param MediaId The media ID that the read request is for. | |
| @param Lba The starting logical block address to read from on the device. | |
| @param BufferSize The size of the Buffer in bytes. | |
| This must be a multiple of the intrinsic block size of the device. | |
| @param Buffer A pointer to the destination buffer for the data. The caller is | |
| responsible for either having implicit or explicit ownership of the buffer. | |
| @retval EFI_SUCCESS The data was read correctly from the device. | |
| @retval EFI_DEVICE_ERROR The device reported an error while attempting to perform the read operation. | |
| @retval EFI_NO_MEDIA There is no media in the device. | |
| @retval EFI_MEDIA_CHANGED The MediaId is not for the current media. | |
| @retval EFI_BAD_BUFFER_SIZE The BufferSize parameter is not a multiple of the intrinsic block size of the device. | |
| @retval EFI_INVALID_PARAMETER The read request contains LBAs that are not valid, | |
| or the buffer is not on proper alignment. | |
