Well, I have the disks in hand - all 4, but there is the overriding level of apprehension. Is there a reference to what I should do *if* I cannot reboot that I should read? Also, after reading the responses to my query about using FAT32 to store data, I decided to follow the suggestions to use Samba to copy the data that needs to be shared with others to my Windows connected NTFS external. So, I am in the process of doing that first even though I have an ext3 backup of the same data. Preparing to jump as I look for my spare parachute....
