Ingabe i-USB flash drive exFAT ifomathiwe?Imuphi usayizi ofanele weyunithi yokwaba efomethiwe?

Ngokuvamile, uma iyunithi yokwabiwa efomethiwe incane, yilapho ulondoloza khona isikhala.

Uma iyunithi yokwabiwa inkulu, kugcinwa isikhathi esiningi, kodwa isikhala siyamoshwa.

Kungase kubonakale sengathi ukwaba amayunithi amancane konga isikhala, kodwa akunjalo.

Lapho ifayela lihlukaniswa libe ngamabhulokhi amaningi, ikakhulukazi uma lawo maseli enkumbulo ehlakazekile, kuthatha isikhathi esiningi ukufunda idatha.

Usayizi weyunithi yokwaba iyunithi encane kunazo zonke isistimu eyifunda futhi ibhale kumadiski, kanye namadivayisi okulondoloza akhiphekayo.

• Ngaphakathi kwesivinini esilinganiselwe, usayizi omkhulu weyunithi yokwaba, isivinini sokufunda/sokubhala siyashesha, futhi okuphambene nalokho.
• Kodwa lapha kufanele sinake inkinga, uma iyunithi eyabelwe inkulu, isikhala esiningi siyamoshwa.
• Ngokuvamile, usayizi weyunithi yokwaba ungaba ngokunganaki.
• Kodwa-ke, uma ukukhethwa kweyunithi kuncane, kuthatha isikhala esincane ukuze ubhale kuze kube sekupheleni kwefayela, futhi okuphambene nalokho.

Uthini usayizi weyunithi yokwabiwa kwefomethi?

Lapho ufometha imemori khadi (i-USB flash drive), khetha iyunithi yokwaba yosayizi weyunithi (eyayaziwa ngokuthi iqoqo).

• Inani lesikhala esinikezwe isistimu yokusebenza kukheli leyunithi ngayinye.
• Lapho udala ukwahlukanisa, inketho yokwaba usayizi weyunithi iyaboniswa.
• Ifayela elilodwa kuphela elingagcinwa ngeyunithi ngayinye yokwabiwa.

Ifayela lihlukaniswe ngamabhulokhi futhi ligcinwe kudiski ngokuya ngosayizi weyunithi yokwabiwa.

• Isibonelo, ifayela likasayizi 512 bytes lithatha 512 bytes wesikhala sokulondoloza lapho iyunithi ukwaba ingamabhayithi 512;
• Ifayela likasayizi 513 bytes lithatha 512 bytes wesikhala sokugcina lapho iyunithi yokwabiwa in 1024 bytes;
• Kodwa uma iyunithi yokwabiwa ingu-4096, izothatha amabhayithi angu-4096 okugcina.

Uma sicabanga ukuthi uyifometha njengeyunithi yesabelo esingu-64K:

• Uma ubhala ifayela elingu-130K, ifayela lithatha isikhala esingu-130/64=2.03.
• Njengoba iseli ngalinye lingabhalela kuphela ifayela ledatha elifanayo, ifayela elingu-130K empeleni lithatha amaseli angu-3.
• 3*64K=192K.Lapho ufometha iyunithi yesabelo esingu-16K, leli fayela lithatha u-130/16 = 8.13 wekhadi le-SD futhi lithatha amayunithi angu-9, 9 * 16K = 144K.

Kungabonakala kulokhu okungenhla ukuthi ukukhetha kweyunithi kuncane, sincane isikhala esithathwe amafayela okugcina, imfucuza encane, kanye nezinga lokusebenzisa ikhadi le-SD.

Izici Zesistimu Yefayela Nemikhawulo

Izici ezilandelayo kanye nemikhawulo yezinhlelo ezihlukahlukene zamafayela:

1. Ku-FAT16 (Windows): sekela ukwahlukanisa okuphezulu okungu-2GB kanye nosayizi wefayela omkhulu ongu-2GB;
2. I-FAT32 (Windows): isekela izingxenye ezifika ku-128GB, futhi usayizi wefayela omkhulu yi-4G;
3. I-NTFS (i-Windows): isekela ubukhulu bosayizi wokuhlukanisa we-2TB kanye nosayizi wefayela omkhulu we-2TB (izici ezisekelwe kulogi azitholakali kuma-flash drives);
4. Ku-exFAT (Windows): isekela ukuhlukaniswa okungafika ku-16EB; usayizi wefayela omkhulu ngu-16EB (oklanyelwe ngokukhethekile ama-flash drive);
5. I-HPFS (OS/2): isekela ukuhlukaniswa okuphezulu kwe-2TB kanye nosayizi wefayela omkhulu ongu-2GB;
6. I-EXT2 ne-EXT3 (Linux): isekela ukuhlukaniswa kwe-4TB, usayizi wefayela omkhulu ngu-2GB;
7. I-JFS (AIX): Sekela ukuhlukaniswa okuphezulu kwe-4P (usayizi webhulokhi = 4k), ifayela eliphezulu 4PB;
8. I-XFS (IRIX): Lolu uhlelo lwefayela olubucayi lwe-64-bit olungasekela izingxenye ze-9E (2 kuya ku-63 amandla).

Ngikhetha kanjani ukufometha usayizi weyunithi yokwaba?

• Kunconywa ukusebenzisa amanani azenzakalelayo lapho ufometha;
• Uhlelo luzolungisa inani elizenzakalelayo elifana kakhulu ngaphandle kokuphathwa mathupha;
• Bese ukhetha Ifomethi Esheshayo, ezoqala ukusebenza ngokushesha.
