Re: [Clonezilla-live] Using CZ with Logocal Volumes

[Johnny S. <li...@op...>]

Unfortunately I dont have a spare 320gb on a single drive anywhere to 
place the image. But if its an identical image, how could this make a 
difference? Would this file image simply be the same image reproduced on 
the second drive?

I believe the issue has something to do with the physical drive going 
from /dev/hdb to /dev/hda on the copy/target, and/or having UID's for 
the drive being different.

Thsi seems to make sense but I dont know how to address it.

Thanks again for all your help :)
