undo LVM?

[Herman Aalderink]

I have no access to my drives. I have to format all ?
During install of 10.04 Alternate 64 I used LVM. The install was not completed.
 Now all 3 drives (in 2 'logical volume groups') are gone.

I need the contents of my (old) HOME (that I marked 'do not format').
I did identify the partition, but no access.

Gparted reported:
 Flags: lvm

Unable to detect filesystem! Possible reasons are:
 -the filesystem is damaged.
 -the filesystem is unknown to Gparted
 -there is no filesystem (unformatted)
