I'd plug the new system drive into the old PC and clone with dd. You can even make the partitions larger and use resize2fs (in case of ext3/4) to enlarge the space after cloning. Once caveat: Your new SATA drives are probably using a block size of 4K instead of 512 bytes, internally. To the OS they still look like they have 512 bytes. But when the partitions are not aligned to 4K boundaries (and I think this is still the case when using fdisk), there is a big performance loss. I also would make sure the whole drive is being written to once, in order to detect bad blocks. badblocks -sw will do this. > Second is a complete reinstall a better option or safer? I'd say just clone it. Remove your /etc/udev/rules.d/*-persistent-*.rules files, so your network interfaces will not be renamed from eth0 to eth1. If you change your CFLAGS, emerge -e world. I'm not sure if you better emerge -e system before (once or even twice) so the toolchain is already compiled with the new settings, maybe someone else will say something about this. Wonko
