FWIW, I did recover data from an LVM that was removed (on purpose) in
part of an upgrade. I couldn't mount the drive as the LVM recovery
procedures listed and I thought I was toast. If I left the drive in the
computer, the computer would try to add the drive back into the LVM no
matter what I tried.
To complicate things even further, the drive was part of a RAID 1 array.
I put the drive into a carrier. As the drive was SATA, I ended up
getting a Thermaltake carrier that supports SATA and IDE (end product
plug). :)
It was many months ago but I used normal recovery tools to pull the data
off of the drive. I would have to look at my notes which are at home.
If I remember I will see if I can find my notes.
Basically, it is possible but I don't know if it is harder as this was
my first time.
