Ko te tikanga mai pūpū reira ki te kōwae mahara i roto i te paerewa moroiti.

hototahi

Me kï reira e kore ai e hototahi ki te pūrere e hangaia tuatahi ki te mahi ki te tikanga SD-kāri te kāri mahara SDHC paerewa e hāngai ana. Ko te take i whai wāhi ai te parau tumu o te whakatutuki (rite puku mārō), rite te ātete ki te paita whakatinana e te i roto i te whakatupuranga o mua o kāri mahara e hāngai ana rāngai-.

Ahakoa, kia tuhia te reira, i roto i te mākete tuwhera he onge whakaaro ōrite, me te he utu (iti, rite ki te tikanga, ki te hoko i te puku mārō o waho).

tāuta te pūnaha kōnae kei i runga i te mea hōu SD-kāri - exFAT, ka FAT32 whanaketanga atu. I roto i nga painga nui o te paerewa hou e whakaarohia ana e Microsoft - whakaiti i roto i te kaha o te taupoki raraunga i roto i te kotahi rängai.

Ko te take i te whakaaro - kāmera, PC, kaipānui kāri, e kore e tautokona tonu te tauira tawhito i te mahara flash, i tukua i runga i te hangarau hōu. I te wa ano, ko reira taa'eraa e tautoko te hunga atu paerewa ranei kia whakawhirinaki i runga i te devaysa āhuatanga pūmārō kore anake, engari ano hoki i runga i to koutou putanga o te mārō i runga taua mea. kia waiho te reira e ka tauturu i te whakamohoa pūmanawa ohie te pūrere - hei tauira, te pūtau taua, ako ki te ite i te SDHC kāri mahara SDXC hou ranei.
