My old HOME was a normal partition.

I did pinpoint that partition already. I have 'complete partition info'
of all partitions on that harddisk (incl all the partition-sizes).

Until today I was thinking the old partition is still there, untouched.
I used RESCUE CDs to try to salvage what I could. Maybe I could salvage
all?
I see all partitions are now ext4 (was ext2 or 3).
(I must have allowed lvm to format. I remember I went for the latest and
the best, ext4. But thought that it would apply only to the partitions
needed for Ubuntu 10.4, incl a NEW home partition.)
Remember I thought it was a new big-harddisk-ADDRESSING-system ....

If the RESCUE-CDs tell the truth (fs is ext4 now) there probably is
nothing to rescue. Unless ext2 to ext 4 change is a minor surgery
(leaving ext2 largely unchanged)
Additional complication: None of my RESCUE CDs can handle ext4.

I lost a good amount of Linux-learning notes (last 4 months). And
electronics-data (last 12 months).
All major stuff was backed up, I am using it. My critical BUs were less
than a day old, perfect score.
