kubuntu: hda -> sda

Now everything is /dev/sd*, even IDE/ATA drives

If you are using a kernel >= 2.6.20, all /dev/hd*s will appear as /dev/sd*s. This is a result of Linux using the libATA drivers for PATA as well as SATA from now on.

а на деле что это тает?

Simplicity as far as Ubuntu concerned: "This will eventually result in us having to only cope with one "storage" subsystem and make our lives somewhat simpler."

And stability for others ;-) I found a good detailed discussion at http://www.justlinux.com/forum/showthread.php?threadid=149316

In short, "The reason is that the PATA code in the kernel is extremely crufty. The libata code is much, much cleaner -- and not only internally: libata handles errors a lot better than the current IDE subsystem does, for instance."

они просто привели всё к универсальной системе, у меня это началось в zenwalk 4.1
