ubukhokho bokugcina i-hard disk drive
Ukusebenza kwehadi disku kuyindlela ebalulekile yokugcinwa kwezicelo, ekutholweni kwamanye amathuba okuchaza ukudala nokusebenza kwezinhawu zogcinwa. I-hard drive zamanje zenquma izinkomba zokulungisa imposo nezinye izinkomba zokulungisa imposo, kunoma ukuqondisi olukhulu olubuke i-ndawo yesendvini nezibalo. Lezi zinhlelo zisebenza ngokwesibonelo ukuthuthukisa ukugcina kwezicelo kanti kube lula ukupheli kwezicelo. Le teknoloji inezinto ezifana ne-Self-Monitoring, Analysis and Reporting Technology (SMART), engcine inkinobho yokuqala yokufa kwehadi. Ngaphezulu, le hard drive yenquma izindlela zokuphela ngokushisa, ukuguqulwa kwezulu, nokungcola komakhulu. Ukusebenza kwehadi disku kuchaziwa ngezindlela ezithile, faka phakathi i-Mean Time Between Failures (MTBF), inqubo yokufa ngonyaka, nokulinganiswa kwezimo. I-hard drive egunyazwe kumasevisi enquma ukusebenza okungenhla, njengezinhloli zokulandela ukushakeka kokuqala nokuhleli okungenhla, okwenza yena into engcono kumasevisi esebenza ngokuphelele kanye namasevisi asemgceni. Ukuqasha kwezinhlelo zakhiwo ezikhulu nokuhlelela kwezokuntula kuholela ekhuliseni ukusebenza kwehadi disku ngemva kwezinsuku, okwenza ukuba kukhona izinqumo eziphumelelayo zogcinwa kwezicelo kanye nezomnotho.
