Migrating Data to New Partition - Copy lost+found?

Probably a silly question, but hey, I'm a newbie. I'm going to move some
data around between partitions and onto a new disk.

Do I need to move the lost+found and .trash directories to the new
partition?

TIA

The lost+found directory is created by the mkfs command (by default).
Unless you really have stuff in the old disk's lost+found, you should
not need to copy it. lost+found is generally only written to by fsck.
If/When it does, you would have presumbably gone there and salvaged
what you could. Any why would you want to copy trash?

It should probably be pointed out that just copying a lost+found
directory would *not* accomplish what is needed. There has to be
a certain amount of disk allocated for holding directory entries,
and it has to be done *before* fsck attempts to write to the
directory. Typically that is accomplished by creating the directory,
and then creating a fair number of files, which are then rm'd. That
leaves space taken up by the directory, and available for fsck.

Hence copying the lost+found from one partition to another, would
ruin the existing lost+found already created by mkfs.

man mklost+found
