Yep, but the only concern is latency. As mentioned, format isn't all 
that scary to use. Do the following :

1. Unmount /space
2. run format
3. Select the disk
4. choose partition [ type p <enter> ]
5. print the partition table [ type p <enter> ]
6. type the number of the /space slice [ It is the same 's' number when 
you do a df -hl ]
7. Delete the slice by entering 0's for the starting, ending and the 
size of the slice.
8. Recreate the swap as necessary.
9. Recreate space.
10. name the label.
11. label the disk.
12. save
13. exit.
14. Freak out [ optional ].
