I have been using LVM for some time now. And my experience has been

Thank you very much both of you. I considered all this, and read a bit
about ddrescue, dd_rescue and dd_rhelp. It seems to me using either of
these would be the least hassle free. I wouldn't need to create the LVM
on my new physical drive. That means no VG name changes and I can just
reboot to my F13 partition and it should just work (?). Also my data is
not mission critical. :)
I am planning to do the following.
1. Boot into my old perfectly working F11 partition
2. Then do one of the following:
# dd_rescue -b 1G -l logfile -o badblocklog /dev/sd[faulty] /dev/sd[new]
# dd_rhelp /dev/sd[faulty] /dev/sd[new] info
or as recommended on the dd_rhelp homepage use "GNU ddrescue",
# ddrescue -n /dev/sd[faulty] /dev/sd[new]
Any suggestions on which of these would be recommended?
Thank you for this link JB. :)
Open source is the future. It sets us free.
