Hello again, this is a second part to my "Holiday Drive Recovery" post
made a few moments ago.

There have been some threads in the past several months on how to
recover a hard drive installation using the `dd` command between to
mismatched drive sizes. I just can't seem to find them. Does anyone
have any links or a procedure?

What I'm referring to is ... `dd` the drive image from a smaller
partition to a larger partition ... now the problem is the larger
partition thinks it is the same size as the smaller one. There had
been a thread at one point of some commands to recover the lost space
... for both Linux and MSWin as I (seem to) remember.

Any pointers or comments would be appreciated. TIA!

I think it may be more effecient to use dd to copy partitions from the bad
drive to files on a larger one (use conv=noerror conv=sync to keep going
over bad blocks and fill in bad data with zeros). Then you can loop mount
the image files and retrieve the data.
