It makes me feel better to check the checksum of the bin file on the SD card itself.
Also, that exe file uses an LHA format archive, which I believe uses the CRC-16 BISYNCH checksum protocol, which is much less robust than the sha1sum or md5sum algorithms. It's unlikely that there'd be an error undetected by this, but it doesn't hurt to double-check.
