Nouveaut\u00e9 WhatsApp : voici comment lib\u00e9rer facilement de l’espace de stockage sur votre smartphone<\/a>Une premi\u00e8re erreur relev\u00e9e onze apr\u00e8s le d\u00e9but de l’exp\u00e9rience<\/p>\nOnze ann\u00e9es plus tard, le journaliste belge install\u00e9 en France vient d’identifier la toute premi\u00e8re erreur, sur une cl\u00e9 USB de la marque PNY.<\/p>\n
\u00ab\u00a0La cl\u00e9 est encore accessible, elle fonctionne toujours\u00a0\u00bb, d\u00e9taille Pierre Dandumont. \u00ab\u00a0Mais il y a au moins un bit qui a chang\u00e9 spontan\u00e9ment de valeur. Si c’est sur une photo par exemple, \u00e7a peut emp\u00eacher l’ouverture du fichier ou \u00e7a peut juste changer la couleur d’un pixel.\u00a0\u00bb<\/p>\n
Une erreur apr\u00e8s onze ans, c’est raccord avec le discours des fabricants, estime le sp\u00e9cialiste.<\/p>\n
\u00ab\u00a0Sur une cl\u00e9 USB, une carte m\u00e9moire, un support \u00e0 base de m\u00e9moire flash, les constructeurs \u00e9voquent g\u00e9n\u00e9ralement une r\u00e9tention de dix ans. Ils consid\u00e8rent donc que si on les stocke sans y toucher, il est possible d’observer apr\u00e8s dix ans la disparition de donn\u00e9es ou l’apparition d’erreurs. Sans que cela soit syst\u00e9matique, heureusement.\u00a0\u00bb<\/p>\n
\u00ab\u00a0Ne jamais stocker des donn\u00e9es importantes sur de la m\u00e9moire flash\u00a0\u00bb<\/p>\n
Existe-t-il des recettes miracles pour pr\u00e9server la sant\u00e9 des anciennes cl\u00e9s USB ? M\u00eame si la temp\u00e9rature du lieu de stockage est par exemple un crit\u00e8re d\u00e9cisif, le journaliste balaie cette question d’un revers de la main.<\/p>\n
\u00ab\u00a0La v\u00e9ritable r\u00e9ponse, c’est qu’il ne faut pas stocker des donn\u00e9es importantes sur de la m\u00e9moire flash. Clairement, on ne sait pas comment \u00e7a peut r\u00e9agir \u00e0 tr\u00e8s long terme. La solution de base, c’est de copier les donn\u00e9es des vieilles cl\u00e9s USB sur un disque dur externe ou sur une cl\u00e9 USB de derni\u00e8re g\u00e9n\u00e9ration. C’est le moyen le plus simple de ne pas perdre de donn\u00e9es.\u00a0\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"\u00ab\u00a0En mai 2015, j’ai rempli de donn\u00e9es al\u00e9atoires une trentaine de cl\u00e9s USB et de cartes m\u00e9moire envoy\u00e9es…\n","protected":false},"author":2,"featured_media":95914,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[11074,12,13,18,17,30824,7176,38,1419,8499,13245,11909,27029,7864,1708,1625,30825,30826,7184,30750,25430,27030,8505,852,687,30827,25357,29024,1635,8508,30828,30829,19835,4022,893,213,1429,7018,5320,4025,7560,30830,24584,30831,30832,12625,73,71,75,72,30833,183,8514,30834,7882,76,74,6335,28267],"class_list":{"0":"post-95913","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-sciences-et-technologies","8":"tag-ambitions","9":"tag-be","10":"tag-be-fr","11":"tag-belgique","12":"tag-belgium","13":"tag-belongings","14":"tag-boss","15":"tag-business","16":"tag-businessman","17":"tag-career","18":"tag-challenge","19":"tag-close-up","20":"tag-corporate","21":"tag-crisis","22":"tag-depression","23":"tag-development","24":"tag-dismissal","25":"tag-dismissed","26":"tag-employee","27":"tag-employer","28":"tag-employment","29":"tag-executive","30":"tag-expert","31":"tag-finance","32":"tag-fire","33":"tag-formal","34":"tag-frustration","35":"tag-hr","36":"tag-human","37":"tag-job","38":"tag-jobless","39":"tag-layoff","40":"tag-loss","41":"tag-management","42":"tag-manager","43":"tag-modern","44":"tag-occupation","45":"tag-office","46":"tag-problem","47":"tag-professional","48":"tag-qualification","49":"tag-quit","50":"tag-recession","51":"tag-recruitment","52":"tag-redundant","53":"tag-resources","54":"tag-science","55":"tag-science-and-technology","56":"tag-sciences","57":"tag-sciences-et-technologies","58":"tag-skills","59":"tag-social","60":"tag-staff","61":"tag-stagnant","62":"tag-stress","63":"tag-technologies","64":"tag-technology","65":"tag-work","66":"tag-workplace"},"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/95913","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/comments?post=95913"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/95913\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media\/95914"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media?parent=95913"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/categories?post=95913"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/tags?post=95913"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
