Ithebula lokuhlukanisa i-master iyinxenye yerekhodi / i-sector boot master equkethe incazelo yamahlukaniso ku- hard disk drive , njengezinhlobo nezayizi zabo. Ithebula lesigaba sokuhlukanisa lihambisana nesignesha ye-disk nekhodi enkulu yokuqalisa ukudala irekhodi le-boot master.
Ngenxa yobukhulu (64 byte) wetafula lokuhlukanisa inkosi, ama-partition amane (16 bytes ngamunye) angachazwa ngedrayivu enzima.
Noma kunjalo, izingxenye ezingeziwe zingasungulwa ngokuchaza ukwahlukana okubonakalayo njengokwesigaba esibekiwe bese kuchaza izingxenye ezithile ezengqondo phakathi kwalolu hlu olweluliwe.
Qaphela: Amathuluzi wokuhlukanisa disk wamahhala kuyindlela elula yokuphatha ukwahlukanisa, ukuhlukanisa izingxenye njenge "Okusebenzayo," nokuningi.
Amanye Amagama weThebula lokuhlukanisa i-Master
Ithebula lehlukanisa kahle ngezinye izikhathi libhekwa njengethebula elihlukanisayo noma ibalazwe lokuhlukanisa, noma lifingqiwe njenge-MPT.
Ukwakhiwa kweThebula lokuQhathaniswa neThenda
Irekhodi ye-boot master ihlanganisa 446 bytes ikhodi, ilandelwa ithebula lokuhlukanisa elinama-bytes angu-64, kanti amabhasi amabili asele agcinwe kwisiginesha sedisk.
Nakhu imisebenzi ethile ye-byte ngayinye ye-16 yethebula lokuhlukanisa inkosi:
| Usayizi (Bytes) | Incazelo |
| 1 | Lokhu kuqukethe ilebuli ye-boot |
| 1 | Ukuqala ikhanda |
| 1 | Ukuqala umkhakha (izinsimbi eziyisithupha zokuqala) nokuqala kwe-cylinder (ama-bits amabili aphezulu) |
| 1 | Le byte ibamba izingxenye eziyisishiyagalombili ezingezansi kwe-cylinder yokuqala |
| 1 | Lokhu kuqukethe uhlobo lokuhlukanisa |
| 1 | Inhloko yokuphela |
| 1 | Imikhawulo yokuphela (izingcezu zokuqala eziyisithupha) nokuphela kwe-cylinder (ama-bits amabili aphezulu) |
| 1 | Le-byte ibamba izingcezu eziyisishiyagalombili ezingezansi ze-cylinder yokuphela |
| 4 | Imikhakha ehamba phambili yehlukaniso |
| 4 | Inombolo yemikhakha ehlukanisweni |
Ithebula le-boot liwusizo ngokukhethekile uma uhlelo olungaphezu kwesisodwa olufakiwe lufakwa kwi-hard drive. Njengoba kukhona ukuhlukanisa okungaphezulu kweyodwa, ilebula ye-boot ikuvumela ukuthi ukhethe ukuthi iyiphi i-OS yokuqalisa .
Kodwa-ke, ithebula lokuhlukanisa lihlale lilandela ithrekhi eyodwa ekhonza njenge "Active" eyodwa ehoxiswa uma kungekho okunye okukhethwa kukho.
Isigaba sohlobo lokwahlukana kwetafula lokuhlukanisa libhekisela ohlelweni lwefayili kulesohlukaniso, lapho i-ID engu-06 noma i-0E yokuhlukanisa isho ukuthi i- FAT , 0B noma i-0C isho ukuthi i-FAT32, futhi i-07 isho i- NTFS noma i-OS / 2 i-HPFS.
Ngokuhlukaniswa okungama-512 bytes kuwo wonke umkhakha, udinga ukwandisa inani eliphelele lemikhakha ngo-512 ukuthola inombolo yezintwana zesahluko esiphelele. Leyo nombolo ingabe ihlukaniswe yi-1,024 ukuze inombolo ibe ngama-kilobytes, bese iphinda i-megabytes, futhi iphinde i-gigabytes, uma idingeka.
Ngemuva kwetafula lokuqala lokuhlukanisa, elivala i-1BE ye-MBR, amanye amatafula okuhlukanisa okwesibini, okwesithathu nowesine ukwahlukana okuyinhloko, at 1CE, 1DE, no-1EE:
| Ukumiswa | Ubude (ama-Bytes) | Incazelo | |
| I-Hex | I-Decimal | ||
| I-1BE - 1CD | 446-461 | 16 | Isigaba esiyinhloko 1 |
| I-1CE-1DD | 462-477 | 16 | Isigaba esiyinhloko 2 |
| I-1DE-1ED | 478-493 | 16 | Isigaba esiyinhloko 3 |
| I-1EE-1FD | 494-509 | 16 | Isigaba esiyinhloko 4 |
Ungafunda inguqulo ye- hex yetafula lokuhlukanisa inkosi ngamathuluzi afana ne-wxHexEditor ne-Active @ Disk Editor.
