Any such workaround would have to go into the SCSI disk driver, not usb-storage. All usb-storage does is transfer commands and results back and forth between the SCSI core and the USB device. If the commands themselves are bad, the SCSI driver needs to be changed to prevent it from issuing them. Although perhaps nothing really needs to be changed. Can you set the low-level format of the SD card (e.g., fdisk) so that the main partition doesn't include the last 8 sectors?
