I lost 4,000 bookmarks to a fucked up Opera browser up date
They were all from the 70's anyhow ! - sorry, couldn't resist lol
I know what you mean though, I lost a hard drive and a backup drive when the controller on my mobo died. Luckily it must have been the main drive that caused it all as with a new sata controlleer, the backup drive was ok
As for the sniffer, that was just to use on a bike that had no sensor bung but it connected to a digital lambda gauge.
My set up is headers 1 and 2 drilled and o2 bungs welded in...
