My bad :-( SATA is not in the same bag as USB. SATA device placement can be changed on hardware changes. Adding or removing PATA drive will automatically change SATA placement reported by BIOS and goof mounting if it is defined by device path. This is not a big problem if you know that it exists, but there is no problem if you use present schema or mounting by label (haven't checked the rest). > > In order to access them you have to know where they are located, with > > different path each time you have to find something that doesn't change. > > Serial numbers are safe bet, they will be the same even across multiple > > installations, or large systems with whole a lot of hard disks.

The openSUSE is created for many different users, and present schema works for all of them. Besides if you replace disk with present schema mount will report error even if disk is formatted ie. mountable, but content doesn't fit in your system. This will prompt you to update configuration. Mount by path on the other hand can happily accept that disk which can lead to problems later. The label system can do the same if label is the same. > I change disks once in 2 years maybe.

If disk serial number is problem as privacy concern, than forget it. The Ethernet card has unique number, motherboard, if computer is brand name, has another one, than IP address, and more can be used to identify person. Of course not by everyone, but privacy in the Internet is illusion. Those that sell privacy services with very broad claims of protection count on peoples lack of knowledge. "Browse Internet anonymously" is one of slogans I can recall. They protect to some extent, but far from total. > But my initial posting was about an internal device > disappearing from the usual mount infrastructure.
