combine several disks together

[Simon Xu]

Is there any software/methods to combine several "disks" together without formatting the harddisk (keep the contents)? I formally used fdisk to divide several disks. Thanks.
Sorry if it is not right forum.

This kind of question really belongs on "General Computing."
Anyhow, the GNU "parted" (Partition Editor) may be able to do this under some circumstances; I'm actually not sure.

You are most correct Ernest. Thanks! I'm moving this to General Computing.
