NTFS Cloning and shrinking

“Honey, I shrunk the filesystem!” Recently I bought a solid-state harddisk, an Intel X25M. I wanted to use this disk in my Windows development system, without having to do a fresh install of Windows XP. I really didn’t want to install all my applications again, not to speak of all the custom configurations and tweaks I usually apply to Windows to make it palatable. So I thought I’d just make a image copy of my old harddisk to this new one, and be done with it.

Freebsd Disk management GEOM : Howto

Pré-requis : présentation de GEOM GEOM [1] [2] est un framework d’abstraction d’accès à des raw-devices via des classes (CONCAT, ELI, LABEL, MIRROR, NOP, RAID3, SHSEC, STRIPE, VINUM) ; chaque classe représente un type d’action sur ces raw-devices. Il est possible de combiner plusieurs classes sur un même device, et ce, dans différents ordres, ce qui éloigne fortement GEOM des autres ” volume managers ” qui ont une typologie beaucoup plus stricte. Un peu de vocabulaire : Une classe implémente un type particulier d’action sur ces raw-devices (disques durs IDE, SATA, SCSI ; clés USB ; fichiers ” filesystem ” montés sur une loopback mdconfig(3)) ; Un provider est le device résultant de l’action de GEOM sur ces raw-devices ; Un consumer est le device sur lequel s’applique la classe, au départ, le device physique. Le handbook comporte un chapitre très complet sur GEOM [3] : ” Chapter 18 GEOM : Modular Disk Transformation “.
