=== Partition ===

Pour repartitionner un  disque : **Parted**

GNU Parted is a package for creating, destroying, resizing, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data between hard disks and disk imaging.\\
It contains a library, libparted, and a command-line frontend, parted, which also serves as a sample implementation and script backend.

=== APM ===

**LINUX** : Problème de disque qui ne veut pas se réveiller.

hdparm -B : Set  Advanced Power Management feature, if the drive supports it.
A low value means aggressive power management and a high value means better performance.
A value of 255 will disable apm on the drive.
