Bonjour,
J'ai eu un souci il y a quelque temps avec un post qui m'a valu à peu de choses près d'être traité de débile sur un autre sous-forum, problème de casse de système, je n'y reviens pas, sauf sur un point : on m'a reproché d'être irresponsable et de vivre dangereusement parce qu'un de mes disques (un WD "WDC WD20EFRX-68EUZN0") en était à >21000 erreurs , mais aussi à chaque compte-rendu rendait entre autres le message suivant :
"SMART overall-health self-assessment test result: PASSED"
et un peu plus loin :
"Warning: ATA error count 21nnn inconsistent with error log pointer 2/3"
(le 2/3 c'est parce que c'est en général le pointer 2, mais parfois le pointer 3)
J'ai effectivement continué à me servir de ce disque, pour voir, en faisant des sauvegardes fréquentes (je suis curieux et je ne m'offre pas 2To de disque tous les jours). Il en est maintenant à près de 46000 erreurs, et pas le moindre fichier perdu, juste parfois une I/o qui semble tarder à se terminer.
J'ai un peu googlé avec les mots-clés
"ATA error count inconsistent with error log pointer 2"
et même avec cette longue liste de mots-clés, on obtient pas mal de réponses: le problème semble répandu.
Un truc que je ne comprends pas, c'est le "inconsistent".
J'ai acheté en même temps 2 dd identiques, l'un me donne des erreurs (environ 46000) et parle d'inconsistence entre 2 mesures, l'autre ne parle pas d' "inconsisitence"
et ne présente que 13 erreurs, pour un nombre d'heures plus faible mais comparable (620 contre 760).
Ces pb peuvent-ils s'expliquer par des faux-contacts dans les cables SATA lors de la première utilisation, par exemple (car j'ai bien eu des bruits bizarres avec certains cables SATA trop raides), et sinon, ce pb, répandu, a-t-il une solution ?
