So the disk internal sector size will prevent cloning of any old drive for use on a new drive??
That's not what I wrote. You can do it, but there will be a performance hit as compared to installing to partitions aligned to the native sector size. I have no idea of the size of the performance hit, but it may be that a new disk degraded may be not be materially different from the native performance of the older HD, or the laptop's disk controller. I simply do not know anything about what the hit can amount to.
There have been reports here on the list: awful perfomance.
Damn, I've got more reading to do. Surely some of the tools take this into account. Bummer -- I really, really didn't want to spend 3 days tweaking a new install.
You do not need a new install, just a less convenient procedure than dd of migrating from old HD to new HD using rsync and/or cp after routine partition and filesystem creation processes, followed up with bootloader installation.
Yes, that's what I did myself recently I migrated to a much larger disk, so I took the chance to enlarge some partitions, add new ones (altering the mount tree), and changing some filesystems types. For instance, you may have originally: / ext3 /home reiser and now you may want: / ext4 /home reiser /usr/share xfs So just format the destination drive, with gparted, for instance (which knows about the new alignment requirements), mount the destination under /mnt, for instance, or /dest, and just rsync source to destination... it doesn't matter if the destination is a dozen partitions and the opriginal just two. That's very easy to do. It is only grub which needs reinstalling, after editing both grub and fstab.
Maybe Clonezilla or something else already has easy already worked out as you suggest something should have?
Maybe. But I'm unsure, it appears to clone the partition layout. Better have a look at their website faq.
Thank you for catching this. Who knows how much fun I would have gotten myself into otherwise.
I do a lot of cloning, but I've not tried any with/without comparisons to see what the performance penalty might amount to. Somewhere on the web surely someone must have described it by now with 3+ years of 4k sector life behind us.
I had simply forgotten about the 500-4000 issue. There are so many details one can forget. :-} - -- Cheers, Carlos E. R.
