I take it that you have installed the drive in a working system? If so, become the superuser. The output of `vgdisplay -v' should show you all the volume groups (VG) on your system, the physical volumes (PV) to which each group is associated, and the logical volumes (LV) that each VG contains. >From this you can tell what VG are on the laptop disk, assuming you know what it's PV name is---typically its the device name. The LV within the volume group must be "active" in order to mount them. Look at the output of `ls -l /dev/mapper' to see if the LV for your laptop VG appear. /dev/mapper contains names of the form brw-rw---- 1 root disk 253, 2 2007-12-15 11:05 vg02-lv00 where "vg02" is the VG name and lv00 is the LV name. Your names will probably be more descriptive than mine. If your laptop VG-LV appear, then you should be able to just mount each with a command like # mount /dev/mapper/vg02-lv00 /mount_point where /mount_point is the path to an empty directory. One of the LV (I suppose) contains your laptop root. In case the LV don't appear in /dev/mappper, then you can active them with # vgchange -a y /dev/vg02 Now, if all is well, the LV for vg02 should appear in /dev/mapper and you can mount them. Dean
