What are some useful commands used for partitioning an additional hard drive from the command-line? Since most published guides steer towards GParted and other graphical utilities, a summary of some command-line sequences would be helpful.
TUNING - RESERVED SPACE, WRITE-BACK & ACCESS TIMES
How to remove the reserved disk space set aside (by default) in case the drive becomes 100% full. Since I is a secondary drive simply for 'data', removing the reserved area ensures the whole drive is available for use.
I'm also curious about write-through vs. write-back and skipping the update of access times (on files and directories) so as to improve performance.
