hi
we have some hard disks, named SATA2 compatible.
as far as i know, the sata2disks dont work with sata1 controllers, only if the disk has a jumper to force to sata1 mode.
these disks dont mention any jumpers in their datasheet, but they say its also sata1 compatible.
how is it then? auto negotiation? i thought that works only in 1 way: the sata2 controller detects the disk speed. the sata1 controller doesnt detet anything.
