Ouaip... c'est clair qu'il y a vraiment pas de quoi s'étriper... Revenons au problème initial : je débarque fraîchement de Windows, j'ai un iMac tout neuf, est ce utile de défragmenter et avec quoi ? Que l'on soit "défragmenteur" ou pas, pour des bonnes raisons (car il y a en a, je n'ai pas dit le contraire) ou pas, je pense qu'on est tous d'accord pour dire que pour cet utilisateur de base, cette opération lui compliquera la vie mais ne lui apportera rien, alors que le même utilisateur de base ressentait le besoin car la différence était sensible sous Winwin. Fermez le banc ?

PS : Pascal, ton histoire de gravure qui ne passait plus c'était sur une machine récente ou plus ancienne ? Car il ne faut pas oublier que les disques durs modernes, même fragmentés, avec leur temps d'accès hyper rapides conservent des débits respectables. Quant à la reconstruction de catalogue effectués par DiskWarrior, elle est bien différente de la fragmentation, car si j'ai bien compris les fichiers ne sont pas déplacés.
When Should I Use DiskWarrior?
Obviously, you should run DiskWarrior when you suspect that there is directory damage on one of your disks. Directory damage can result in a disk not mounting (not appearing on the desktop when the computer is started), missing files or folders, an inability to move or copy files, or crashes when files are used.
The best use of DiskWarrior is for preventative maintenance of your disks. Many forms of directory damage do not manifest themselves until long after the damage has actually occurred.
You can prevent this damage from escalating by running DiskWarrior on your disks regularly - we suggest at least once each month. DiskWarrior will rebuild your disk directory, eliminating all existing directory damage. The directory DiskWarrior creates is also optimized for maximum directory performance, and this will speed up the performance of your disk.
What Are The Other Advantages?
DiskWarrior optimizes your directory for maximum performance. Directory optimization typically results in a 50% to 60% decrease in the time it takes programs to scan the directory and a 10% to 20% decrease in startup time. Other programs may not provide the true directory optimization provided by DiskWarrior.
DiskWarrior compares your old directory with the new rebuilt directory and determines if there have been any changes to the number or contents of your files and folders. It then lists any differences it finds in the DiskWarrior Report. You'll know right away what files and folders are affected by directory damage. The report lists the problems found by file, making it easy for you to see what files and folders you need to check in the preview.
DiskWarrior's patented preview feature lets you examine the files and folders on your damaged disk as they will appear after the directory is repaired but before any changes are made to the disk. This assures you that you will get the expected results before any changes are made permanent.
When enabled, DiskWarrior's hardware monitoring capability can notify you if your drive devices are in danger of failing. This notice can give you valuable warning, allowing you the opportunity to back up your files before the drive becomes completely inaccessible. Without such a back-up, your may be left with an expensive data recovery service as the only way to get your data back.
DiskWarrior verifies your rebuilt directory to ensure that it is error free. For protection from interruptions such as power loss, DiskWarrior uses a unique fail-safe method of replacing the damaged directory with the repaired directory. With DiskWarrior, you never have to worry about the safety of your files.
If there is a system folder on your disk, DiskWarrior will ensure that it is blessed. No more flashing question mark!
DiskWarrior safely rebuilds journaled disks. It also checks System and Finder files for damage, eliminates a common cause of system crashes by checking custom icon files for corruption, and repairs the wrapper volume System files caused when HFS Plus disks are initialized under Mac OS 9.0 - 9.0.4, allowing Macs with these disks to start up.
