I know that. What I meant was which segments in the hex dump correlate to which segments in the text version of the dianostic mode page? How long are the segments? 8 bytes? The way it is formatted something could hint that? Or is it just 4 bytes which another formatting suggests? >> When I run this command >> sg_ses --page=2 /dev/sg30 --raw >> >> I get output that looks like: >> 00 00 00 00 00 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 >> 01 00 00 00 01 00 00 00 00 00 01 00 01 00 01 00 >> 00 00 00 40 06 00 00 47 06 00 00 47 06 00 00 47 >> 00 00 00 00 01 00 2c 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 06 00 00 00 06 00 00 00 >> 06 00 00 00 06 00 00 00 >> >> There are 26 segments starting with 01 00 00 00, and 27 with 06.

I probably do that, which is why I asked how to understand the hex dump. > I'd firstly validate that your lights can be flashed with the ses > driver ... if they can, then look for a mistake in the hex dump. How can I validate that my lights can be flashed with the SES driver?
