Cholakwika pa deta (CRC) sichimangokhala ndi disk yokhazikika, komanso ndi zina: USB flash, kunja HDD. Izi nthawi zambiri zimachitika pazifukwa zotsatirazi: pamene mukutsitsa mafayilo pamtsinje, kukhazikitsa masewera ndi mapulogalamu, kukopera ndi kulemba mafayilo.
CRC Mphululo Njira Zowonongeka
Cholakwika cha CRC chikutanthauza kuti checksum ya fayilo siyikugwirizana ndi yomwe iyenera kukhala. Mwa kuyankhula kwina, fayilo iyi yawonongeka kapena yasinthidwa, kotero pulogalamuyo silingathe kukonza.
Malingana ndi momwe zinthuzo zakhalira, vutoli limapangidwa.
Njira 1: Gwiritsani ntchito fayilo yosungirako ntchito / chithunzi
Vuto: Poika masewera kapena pulogalamu pamakompyuta kapena pamene mukuyesera kujambula chithunzi, cholakwika cha CRC chimachitika.
Yothetsera: Izi zimachitika kawirikawiri chifukwa fayiloyi imasulidwa ndi kuwonongeka. Izi zingachitike, mwachitsanzo, ndi intaneti yosakhazikika. Pankhani iyi, muyenera kutsegula womanganso. Ngati ndi kotheka, mungagwiritse ntchito kampani yojambulira kapena pulogalamu yamtunduwu, kuti pasakhale kusankhulana kwachinsinsi mukamatsitsa.
Kuonjezera apo, fayilo yowonongeka iwonongeke, kotero ngati muli ndi vuto mukatha kuwongolera, muyenera kupeza njira ina yotsatsira ("kioo" kapena mtsinje).
Njira 2: Yang'anani diski ya zolakwika
Vuto: Palibe mwayi wa diski yonse kapena mafakitale osungidwa pa disk disk, yomwe inagwira ntchito popanda mavuto kale, musagwire ntchito.
Yothetsera: Vuto likhoza kuchitika ngati mawonekedwe a disk disk akusweka kapena ali ndi magawo oipa (mwakuthupi kapena omveka). Ngati makampani osagonjetsedwa sangathe kuwongolera, ndiye kuti zotsalirazo zingathetsedwe pogwiritsa ntchito mapulogalamu olakwika okonzekera pa disk hard.
M'modzi mwa nkhani zathu tanena kale momwe tingakonzere mavuto a fayilo dongosolo ndi magawo pa HDD.
Werengani zambiri: Njira ziwiri zowonjezeretsa magawo oipa pa disk
Njira 3: Pezani kugawa koyenera ku mtsinje
Vuto: Kuyika kwafayilo kojambulidwa kudutsa mumtsinje sikugwira ntchito.
Yothetsera: Mwinamwake, mumasula zomwe zimatchedwa "kugawanika kogawidwa." Pachifukwa ichi, muyenera kupeza fayilo yomweyo pa malo amodzi ndikutulutsanso. Fayilo yowonongeka ikhoza kuchotsedwa pa disk hard.
Njira 4: Fufuzani CD / DVD
Vuto: Ndikayesera kukopera mafayilo ku CD / DVD, kulakwitsa kwa CRC kumatuluka.
Yothetsera: Mwinamwake, kuwonongeka kwa disk. Fufuzani izo chifukwa cha fumbi, dothi, zikopa. Ndi chilakolako chodziwika bwino, mwinamwake, palibe chomwe chidzachitike. Ngati nkhaniyo ndi yofunikira kwambiri, mukhoza kuyesa kugwiritsa ntchito zowonjezera kuti mubwezeretse deta ku disks zowonongeka.
Pafupifupi zochitika zonse, imodzi mwa njirazi ndi yokwanira kuthetsa vuto lomwe lawonekera.
