I have a 2TB USB drive plugged into CentOS 5.5 that will be formatted with ext3 and will only be used for file-level backups.
I've always partitioned my drives but a while ago when I had setup Amazon EBS the docs said to just format the whole device (eg. mkfs /dev/sdf instead of /dev/sdf1) and ext3 would warn you but allow you to do so, which it did.
As I understand it, partitioning in this case will only be necessary if I want to boot from the USB drive which will not be happening and I really want to save those 512 bytes.
Skip or keep the single partition? Why?
Thanks
