I'm doing our normal Clonezilla Backup procedure and ran out of disk space for the first time. The normal person who does this is on vacation. I put the new hard drive in for the backup, but when I ran Clonezilla it didn't recognize it. I looked in Server Manger and it shows it as Unknown with a red arrow and not initialized. It's shown as unallocated. What do I need to do at this point? Do you have instructions or a link to instructions? I'm new to working with servers, etc. I probably need to format the new external drive but I'm not sure how. This is a simple server, without VM's, etc.
Thanks!
