Technically it would work, but you'll most probably encounter a huge performance drop. Partitions on SSD drives need to be properly aligned to the block boundaries (4k), because they use a blocksize of 4k (at least the ones I own), similar to the WD "advanced format". Most of the rotational drives (except those who use "advanced format" or similar) use a 512 byte blocksize. DDing such a disk to a solid state device could be a bad idea. The best way to do it in my opinion is to backup all partitions using rsync (*), partitioning and formatting the SSD with proper alignment, using rsync to transfer the data back, and simply re-install GRUB2. I have done that quite often, without any problems. (*) rsync -avxHSAX /source/ /target Don't forget to switch to the deadline elevator, it works a lot better than cfq in combination with non-rotational drives. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
