isn't it a good idea? i just want to make a separate partition for drivers of laptop? :\
Partitions, in my opinion, have no reason to be used anymore.
If you want to artificially limit the amount of space available to certain subsets of data, use quotas.
File systems are sufficiently stable, that there's no point in having a backup on a separate partition of the same disk.
There's no reason to split a disk with partitions, as it will only limit your options when one of the partitions runs out of space.
There's really only one reason left, where partitions make any sense:
If you run different operating systems on a PC, with incompatible file systems.
