\u00ab Qu\u2019est-ce qui arrive si je formate mon disque dur ? \u00bb C\u2019est sans doute l\u2019une des questions les plus fr\u00e9quentes chez les nouveaux utilisateurs d\u2019ordinateur.<\/p>\n

Did you know every hard drive begins life being formatted at the factory where it was built? This may surprise you since formatting seems like something you only do when you have a major problem with your drive. But formatting a hard drive can be useful in many different situations. So <\/span>what is formatting<\/b>, really? And what does formatting a hard drive do?
\r\n<\/span><\/p>\n

Quand un disque est format\u00e9, tout ce qui s\u2019y trouvait auparavant est effac\u00e9. Toutes les donn\u00e9es sont supprim\u00e9es et l\u2019espace est lib\u00e9r\u00e9 pour accueillir de nouvelles donn\u00e9es et des syst\u00e8mes de fichiers. Il y a plusieurs raisons pour lesquelles on pourrait vouloir formater un disque. Vous pourriez \u00eatre pr\u00e9occup\u00e9 par la s\u00e9curit\u00e9, vouloir r\u00e9utiliser le mat\u00e9riel ou installer un nouveau syst\u00e8me de fichiers sur votre appareil. Ou encore, vous pourriez tenter de corriger des erreurs majeures sur le p\u00e9riph\u00e9rique.<\/span><\/p>\n

Peu importe la raison, le r\u00e9sultat final est que, si c\u2019est bien fait, <\/span>le formatage d\u2019un disque dur <\/b>am\u00e9liore les performances de votre appareil. Mais avant de voir ce que le formatage d\u2019un disque fait r\u00e9ellement, vous devez comprendre <\/span>comment formater un disque dur <\/b>au d\u00e9part.<\/span><\/p>\n

Comment formater un disque dur<\/h2>\n

Maintenant que vous savez ce que signifie \u00ab formater \u00bb, passons \u00e0 l\u2019\u00e9tape pratique. Avant de formater un disque dur, assurez-vous de sauvegarder vos donn\u00e9es. Ne formatez jamais un disque si vos fichiers ne sont pas aussi enregistr\u00e9s ailleurs ! Le formatage efface toutes les donn\u00e9es du disque concern\u00e9. (Pour mieux comprendre la suppression de donn\u00e9es, lisez Vos donn\u00e9es sont-elles vraiment disparues ?)<\/span><\/a><\/span><\/p>\n

Formater un disque dur <\/b>est en fait assez simple. Nous allons d\u2019abord voir comment faire un formatage rapide qui ne supprime pas vos donn\u00e9es. Que vous utilisiez Windows ou Mac, il y a cinq \u00e9tapes pour <\/span>formater un disque<\/b>.<\/span><\/p>\n

Formatage rapide dans Windows<\/span><\/h3>\n

Voici comment formater un disque dur non amor\u00e7able dans Windows.<\/span><\/p>\n

    \n
  1. If your drive isn\u2019t already installed on your PC, connect the hard drive to the computer.<\/span><\/li>\n
  2. Open Windows Explorer, and navigate to the left side of the window. Right-click on your drive and select \u201cFormat.\u201d<\/span><\/li>\n
  3. Pick the file system and name it under \u201cVolume Label.\u201d<\/span><\/li>\n
  4. Perform a \u201cQuick Format.\u201d<\/span><\/li>\n
  5. Click \u201cStart.\u201d<\/span><\/li>\n<\/ol>\n

    Une fois le processus termin\u00e9, vous aurez un disque dur vierge pr\u00eat \u00e0 \u00eatre utilis\u00e9. Passons maintenant aux \u00e9tapes pour les Mac\u00a0!<\/span><\/p>\n

    Formatage rapide pour Mac<\/span><\/h3>\n

    Voici comment formater un disque dur non amor\u00e7able sur Mac.<\/span><\/p>\n

      \n
    1. Navigate to the Disk Utility app.<\/span><\/li>\n
    2. Go to \u201cChoose View\u201d and select \u201cShow All Devices.\u201d<\/span><\/li>\n
    3. Click on the disk you want to erase.<\/span><\/li>\n
    4. Rename the disc, choose the format you want (APFS or Mac OS Extended), and select the \u201cGUID Partition Map\u201d scheme.<\/span><\/li>\n
    5. Click \u201cErase.\u201d<\/span><\/li>\n<\/ol>\n

      Le formatage rapide fait du bon travail pour nettoyer votre disque dur, mais il ne supprime pas toutes vos donn\u00e9es de fa\u00e7on d\u00e9finitive. Si vous voulez effacer compl\u00e8tement et de mani\u00e8re s\u00e9curitaire votre disque, notamment pour le vendre ou le donner, un formatage complet est n\u00e9cessaire.<\/span><\/p>\n

      Le formatage complet est aussi simple que le formatage rapide, mais n\u2019oubliez pas\u00a0! Un formatage complet efface toutes les donn\u00e9es de votre disque dur, donc v\u00e9rifiez bien si c\u2019est vraiment ce que vous voulez faire <\/span>avant <\/span><\/i>d\u2019aller plus loin\u00a0!<\/span><\/p>\n

      Formatage complet dans Windows<\/span><\/h3>\n

      Si votre syst\u00e8me d\u2019exploitation est Windows, suivez les \u00e9tapes mentionn\u00e9es plus haut, sauf l\u2019\u00e9tape\u00a04.\u00a0<\/span><\/p>\n

        \n
      1. If your drive isn\u2019t already installed on your PC, connect the hard drive to the computer.<\/span><\/li>\n
      2. Open Windows Explorer, and navigate to the left side of the window. Right-click on your drive and select \u201cFormat.\u201d<\/span><\/li>\n
      3. Pick the file system and name it under \u201cVolume Label.\u201d<\/span><\/li>\n
      4. Click \u201cStart.\u201d<\/span><\/li>\n<\/ol>\n

        Si vous avez un Mac, les trois premi\u00e8res \u00e9tapes sont identiques, que vous proc\u00e9diez \u00e0 un formatage rapide ou complet\u00a0:<\/span><\/p>\n

          \n
        1. Navigate to the Disk Utility app.<\/span><\/li>\n
        2. Go to \u201cChoose View\u201d and select \u201cShow All Devices.\u201d<\/span><\/li>\n
        3. Click on the disk you want to erase.<\/span><\/li>\n
        4. Click \u201cEdit\u201d in the upper left corner of the window.<\/span><\/li>\n
        5. Click \u201cDelete APFS Volume\u201d from the menu bar.<\/span><\/li>\n
        6. You may see an \u201cErase Group Volume\u201d button appear. If so, click the button.<\/span><\/li>\n
        7. If prompted, click \u201cDelete.\u201d<\/span><\/li>\n<\/ol>\n

          Que fait le formatage d\u2019un disque dur ?<\/span><\/h2>\n

          Alors, <\/span>que se passe-t-il lorsque vous formatez un disque<\/b> ? Peu importe la raison pour laquelle vous formatez votre disque dur, le r\u00e9sultat sera toujours le m\u00eame. Voici \u00e0 quoi vous attendre.<\/span><\/p>\n

          R\u00e9sultat n\u00b01 : Nettoie et r\u00e9initialise le syst\u00e8me de fichiers<\/span><\/h3>\n

          Lorsque vous formatez un disque dur, vous s\u00e9lectionnez le type de syst\u00e8me de fichiers que vous voulez que le nouveau disque dur format\u00e9 utilise (comme NTFS ou exFAT). En proc\u00e9dant au formatage, les informations du disque dur sont essentiellement effac\u00e9es et toute la structure de sauvegarde des nouvelles donn\u00e9es est modifi\u00e9e.<\/p>\n

          R\u00e9sultat n\u00b02 : Am\u00e9liore les performances de l\u2019appareil<\/span><\/h3>\n

          L\u2019un des principaux avantages de formater un disque dur ou un ordinateur est l\u2019am\u00e9lioration des performances de l\u2019appareil. Le formatage agit comme une remise \u00e0 z\u00e9ro qui r\u00e9tablit le fonctionnement tel qu\u2019il \u00e9tait au moment de l\u2019achat. Mais qu\u2019est-ce que le formatage d\u2019un disque dur fait exactement pour \u00eatre aussi avantageux ?<\/p>\n

          Quand vous formatez, l\u2019espace du disque est lib\u00e9r\u00e9 pour vous. Une fois qu\u2019une quantit\u00e9 importante d\u2019espace de stockage est disponible, votre appareil a acc\u00e8s \u00e0 plus de m\u00e9moire et traite les commandes beaucoup plus efficacement. En termes simples, plus vous avez d\u2019espace de stockage disponible, plus votre ordinateur est rapide\u202f! Donc, que votre ordinateur soit lent ou qu\u2019il ait des bogues \u00e9tranges, formater le disque pourrait aider.<\/p>\n

          Formater un disque dur permet aussi de nettoyer l\u2019espace disque en supprimant du contenu inutile ou nuisible. Cela comprend des logiciels malveillants et d\u2019autres virus que votre antivirus n\u2019a peut-\u00eatre pas d\u00e9tect\u00e9s. Ces applications font de leur mieux pour \u00e9liminer les menaces, mais elles ne sont pas parfaites et peuvent parfois en manquer.<\/p>\n

          Les fichiers n\u00e9cessaires au fonctionnement du syst\u00e8me d\u2019exploitation (OS) peuvent s\u2019endommager avec le temps et ralentir votre appareil. En formatant un disque dur, le syst\u00e8me d\u2019exploitation est r\u00e9install\u00e9. Les erreurs ou d\u00e9faillances sont supprim\u00e9es, et les performances du syst\u00e8me sont r\u00e9tablies \u00e0 leur meilleur niveau.<\/p>\n

          R\u00e9sultat n\u00b03 : Supprime les donn\u00e9es<\/span><\/h3>\n

          Est-ce que le formatage d\u2019un disque efface les donn\u00e9es\u202f? Oui\u202f! En fait, la majorit\u00e9 des gens formatent un disque dur pour en supprimer le contenu. Si vous n\u2019avez plus besoin des informations qui y sont stock\u00e9es, le formatage est une fa\u00e7on rapide et simple de tout effacer.<\/p>\n

          Comme toujours, il est recommand\u00e9 de sauvegarder automatiquement vos donn\u00e9es personnelles sur une base r\u00e9guli\u00e8re afin de pr\u00e9venir toute perte impr\u00e9vue. Mais si vous devez formater un disque pour changer de syst\u00e8me de fichiers, le nettoyer ou am\u00e9liorer les performances, vous ne voulez pas perdre vos donn\u00e9es les plus r\u00e9centes. Prenez donc quelques minutes pour sauvegarder manuellement votre disque dur sur un support externe avant de proc\u00e9der.<\/p>\n

          Maintenant que vous savez ce que signifie formater un disque dur d\u2019ordinateur, il n\u2019y a aucune raison de ne pas le faire pour am\u00e9liorer les performances. Cela dit, cela peut \u00eatre risqu\u00e9 si vous n\u2019\u00eates pas bien pr\u00e9par\u00e9\u202f!<\/p>\n

          Comme toujours, vous devriez sauvegarder automatiquement vos donn\u00e9es r\u00e9guli\u00e8rement afin de pr\u00e9venir toute perte impr\u00e9vue<\/a>. Mais si vous devez formater un disque pour changer de syst\u00e8me de fichiers, le nettoyer ou am\u00e9liorer les performances, vous ne voulez pas perdre vos donn\u00e9es les plus r\u00e9centes. Prenez donc quelques minutes pour faire une sauvegarde manuelle de votre disque dur avant de le formater.<\/span><\/p>\n

          Si vous avez accidentellement format\u00e9 votre disque sans avoir de sauvegarde r\u00e9cente, tout espoir n\u2019est pas perdu. Un sp\u00e9cialiste qualifi\u00e9 en r\u00e9cup\u00e9ration de disques durs pourrait \u00eatre en mesure de retrouver et restaurer vos donn\u00e9es \u2014 m\u00eame \u00e0 partir d\u2019un disque format\u00e9. <\/span>Communiquez avec DriveSavers d\u00e8s aujourd\u2019hui pour savoir si vos donn\u00e9es peuvent \u00eatre r\u00e9cup\u00e9r\u00e9es<\/span><\/a>\u202f!<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
