Ka shum\u00eb informacion n\u00eb rrjet rreth SMART dhe vlerave t\u00eb atributeve. Por nuk kam hasur n\u00eb p\u00ebrmendje p\u00ebr disa momente t\u00eb r\u00ebnd\u00ebsishme, t\u00eb cilat i di nga njer\u00ebz q\u00eb merren me hulumtimin e mediave t\u00eb informacionit.<\/p>\n

Kur tregova p\u00ebrs\u00ebri nj\u00eb mikut tim pse nuk duhet t'i besohet pa kushte leximeve t\u00eb SMART dhe pse \u00ebsht\u00eb m\u00eb mir\u00eb t\u00eb mos p\u00ebrdoren monitor\u00ebt klasik\u00eb t\u00eb SMART-it vazhdimisht, m\u00eb erdhi nje ide q\u00eb t'i regjistroj fjal\u00ebt e th\u00ebna n\u00eb form\u00ebn e nj\u00eb grupi tezash me shpjegime.

\n1) Duhet t\u00eb p\u00ebrdoren me shum\u00eb kujdes programet p\u00ebr monitorimin automatik t\u00eb atributeve SMART.<\/b><\/p>\n

Ajo q\u00eb e dini si atribute SMART nuk ruhet n\u00eb form\u00eb t\u00eb gatshme, por gjenerohet n\u00eb momentin q\u00eb i k\u00ebrkoni. Ato llogariten n\u00eb baz\u00eb t\u00eb statistikave t\u00eb brendshme, t\u00eb akumuluara dhe p\u00ebrdorura nga programi i mikrokontrollerit t\u00eb pajisjes gjat\u00eb funksionimit. <\/p>\n

Nj\u00eb pjes\u00eb e k\u00ebtyre t\u00eb dh\u00ebnave pajisjes p\u00ebr t\u00eb siguruar funksionin kryesor nuk i nevojitet. Dhe ato nuk ruhen, por formohen \u00e7do her\u00eb q\u00eb \u00ebsht\u00eb e nevojshme. Prandaj, kur ndodhi k\u00ebrkesa p\u00ebr atributet SMART, programi i mikrokontrollerit aktivizon nj\u00eb num\u00ebr t\u00eb madh procesesh, t\u00eb cilat jan\u00eb t\u00eb nevojshme p\u00ebr t\u00eb marr\u00eb t\u00eb dh\u00ebnat e munges\u00ebs. <\/p>\n

Por k\u00ebto procese jan\u00eb pak t\u00eb p\u00ebrputhshme me procedurat q\u00eb kryhen gjat\u00eb ngarkes\u00ebs s\u00eb pajisjes nga operacionet e leximit-shkrimit.<\/p>\n

N\u00eb nj\u00eb bot\u00eb ideale, kjo nuk duhet t\u00eb shkaktonte ndonj\u00eb problem. Por n\u00eb realitet, firmware-t e disqeve t\u00eb hardit shkruhen nga njer\u00ebz t\u00eb zakonsh\u00ebm. T\u00eb cil\u00ebt mund t\u00eb gabojn\u00eb dhe e b\u00ebjn\u00eb k\u00ebt\u00eb. Prandaj, n\u00ebse k\u00ebrkoni atributet SMART gjat\u00eb kryerjes aktive t\u00eb operacioneve t\u00eb leximit-shkrimit nga pajisja, rritet ndjesh\u00ebm probabiliteti q\u00eb di\u00e7ka t\u00eb shkoj\u00eb keq. P\u00ebr shembull, mund t\u00eb d\u00ebmtohen t\u00eb dh\u00ebnat n\u00eb tamponin e leximit ose shkrimit t\u00eb p\u00ebrdoruesit.<\/p>\n

Pretendimi p\u00ebr rritjen e rreziqeve nuk \u00ebsht\u00eb nj\u00eb p\u00ebrfundim teorik, por nj\u00eb v\u00ebzhgim praktik. P\u00ebr shembull, \u00ebsht\u00eb i njohur nj\u00eb bug q\u00eb ka ndodhur n\u00eb firmware-in e HDD Samsung 103UI, ku gjat\u00eb kryerjes s\u00eb k\u00ebrkes\u00ebs p\u00ebr atributet SMART, t\u00eb dh\u00ebnat e p\u00ebrdoruesit jan\u00eb d\u00ebmtuar.<\/p>\n

Pra ndiheni mir\u00eb, mos e konfiguroni verifikimin automatik t\u00eb atributeve SMART. N\u00ebse nuk jeni t\u00eb sigurt se para k\u00ebsaj jepet komanda p\u00ebr pastrimin e memorie (Flush Cache). Ose, n\u00ebse \u00ebsht\u00eb e nevojshme, konfiguroni ekzekutimin e verifikimeve sa m\u00eb rrall\u00eb q\u00eb t\u00eb jet\u00eb e mundur. N\u00eb shum\u00eb programe monitorimi, koha e vendosur si e parazgjedhur mes verifikimeve \u00ebsht\u00eb rreth 10 minuta. Kjo \u00ebsht\u00eb shum\u00eb shpesh. Sidoqoft\u00eb, k\u00ebto verifikime nuk jan\u00eb nj\u00eb ila\u00e7 p\u00ebr daljen e papritur jasht\u00eb sh\u00ebrbimi t\u00eb diskut (ila\u00e7i \u00ebsht\u00eb vet\u00ebm rezervimi). Nj\u00eb her\u00eb n\u00eb dit\u00eb, mendoj se \u00ebsht\u00eb plot\u00ebsisht e mjaftueshme.<\/p>\n

K\u00ebrkesa p\u00ebr temperatur\u00ebn gjat\u00eb nisjes s\u00eb proceseve p\u00ebr llogaritjen e atributeve nuk sjell ndonj\u00eb problem dhe mund t\u00eb realizohet shpesh. Sepse, me implementimin e duhur, k\u00ebt\u00eb e b\u00ebjm\u00eb p\u00ebrmes protokollit SCT. P\u00ebrmes SCT dor\u00ebzohet vet\u00ebm ajo q\u00eb tashm\u00eb dihet. K\u00ebto t\u00eb dh\u00ebna p\u00ebrdit\u00ebsohen automatikisht n\u00eb sfond.<\/p>\n

2) T\u00eb dh\u00ebnat e atributeve SMART shpesh jan\u00eb t\u00eb pasakta.<\/b><\/p>\n

Mikroprogrami i hard diskut ju tregon at\u00eb q\u00eb mendon se \u00ebsht\u00eb e nevojshme t\u00eb tregohet dhe jo at\u00eb q\u00eb ndodh n\u00eb t\u00eb v\u00ebrtet\u00eb. Nj\u00eb shembull m\u00eb ilustrues \u00ebsht\u00eb atributi i pest\u00eb, numri i sektor\u00ebve t\u00eb ri-ndar\u00eb. Specialist\u00ebt e rikuperimit t\u00eb t\u00eb dh\u00ebnave e din\u00eb mir\u00eb se hard disku mund t\u00eb tregoj\u00eb n\u00eb atributin e pest\u00eb zero num\u00ebr rikalit\u00ebsh, edhe pse ata ekzistojn\u00eb dhe vazhdojn\u00eb t\u00eb shfaqen. <\/p>\n

I b\u00ebra nj\u00eb pyetje specialistit q\u00eb studion hard disqet dhe heton mikroprogramet e tyre. E pash\u00eb se \u00e7far\u00eb parimi ndiqet nga firmware e pajisjes p\u00ebr t\u00eb fshehur faktin e rikrijimit t\u00eb sektor\u00ebve, dhe kur \u00ebsht\u00eb e mundur t\u00eb flitet p\u00ebr t\u00eb p\u00ebrmes atributeve SMART.<\/p>\n

Ai u p\u00ebrgjigj se nuk ekziston nj\u00eb rregull t\u00eb p\u00ebrgjithsh\u00ebm sipas t\u00eb cilit pajisjet tregojn\u00eb ose fshehin realitetin. Logjika e programuesve q\u00eb shkruajn\u00eb firmware p\u00ebr hard disqet ndonj\u00ebher\u00eb duket shum\u00eb e \u00e7uditshme. Duke studiuar firmware t\u00eb modeleve t\u00eb ndryshme, ai vuri re se shpesh vendimi \"trego ose fsheh\" merret n\u00eb baz\u00eb t\u00eb nj\u00eb seti parametrash, t\u00eb cil\u00ebt nuk \u00ebsht\u00eb e qart\u00eb si lidhen me nj\u00ebri-tjetrin dhe me burimet e mbetura t\u00eb hard diskut.<\/p>\n

3) Interpretimi i treguesve SMART \u00ebsht\u00eb specifik p\u00ebr vendor\u00ebt.<\/b><\/p>\n

P\u00ebr shembull, n\u00eb SiGate \u00ebsht\u00eb m\u00eb mir\u00eb t\u00eb mos i kushtoni shum\u00eb v\u00ebmendje \"vlerave t\u00eb k\u00ebqija\" raw t\u00eb atributeve 1 dhe 7, derisa t\u00eb tjerat t\u00eb jen\u00eb n\u00eb norm\u00eb. N\u00eb disk\u00ebt e k\u00ebtij prodhuesi, vlerat e tyre t\u00eb pakt\u00ebn mund t\u00eb rriten gjat\u00eb p\u00ebrdorimit normal.<\/p>\n

\"Pak

\nP\u00ebr t\u00eb vler\u00ebsuar gjendjen dhe burimin e mbetur t\u00eb diskut t\u00eb fort\u00eb, s\u00eb pari rekomandohet t\u00eb kushtoni v\u00ebmendje parametra 5, 196, 197, 198. Gjithashtu, ka kuptim t\u00eb orientoheni pik\u00ebrisht n\u00eb vlerat absolute, raw, dhe jo n\u00eb ato t\u00eb p\u00ebrpunuara. P\u00ebrpunimi i atributeve mund t\u00eb kryhet n\u00eb m\u00ebnyra q\u00eb nuk jan\u00eb t\u00eb qarta, t\u00eb ndryshme n\u00eb algoritmet dhe firmware-t e ndryshme. <\/p>\n
