[nflug] data recovery

[eric at bootz.us]

My apologies for blaming LVM , it's just my lack of knowledge and  
realizing that I should set systems up with file systems I understand  
better or partitions schemes

But the senario is this:

For sure two scsi drives do not show up in the scsi bios controller  
the other two scsi drives still show up, but I cannot do lvscan or  
find containers on them when booting with 5.1.1 knoppix live or a  
CentOS scsi When I installed CentOS on another scsi drive that I had  
laying around I made sure that the install did not touch the other two  
scsi drives they show up in the centOS build as sdb and sdc in /dev,  
but centOS doesn't recognize the file system and to reiterate, cannot  
see any other containers than itself.

Is it possible that the two scsi drives that are still good have  
recoverable data on them?
