    I just got one of those 2nd HDD caddy's that makes it possible to fit a HDD/SSD in the place of the DVD drive, and I noticed this flip switch, it is on the inside of the caddy, beside the SATA connectors,

    What does it do ?

    There are plenty of similar caddys on ebay that have pictures showing a similar flip switch.

    it's a switch that, when slid all the way toward the SATA interface, will prevent the diagnostic pin from making a connection with the ground pins. here's an illustration. depending on the model of your machine, you may need to utilize the switch if you're having sleep/standby/shutdown issues after caddying your drive. (you can read about those kinds of issues here and here.)

    i personally have a caddy with this switch that i use for a storage drive and it worked plug-and-play--probably because i don't boot from the caddied drive.

    Thanks for the info.

    I wonder though if there is any risk of running that SATA adapter in one way or the other ..

    you either want to boot in the drive manufacturer's diagnostic mode or not. whether or not that has any effect on the data/software installed to the disk (e.g. sleep/standby/shutdown in windows) is an ancillary matter--and the only "risk," if it can even be appropriately called that.
