Māhele 5: I ka wā e make ai ke Kāleka Kāleka (0 MB / No Media), Monolithic NAND Chip-Off Recovery¶

He aha inā ʻaʻole hōʻike kāu kāleka SD, kāleka microSD, a i ʻole kāleka CFexpress i kona hiki i ka Disk Management i nā mea āpau, hōʻike 0 MB, No Media, 31.5 MB RAW, a wehe paha i kēlā me kēia 3 kekona?

Pehea i kūkulu ʻia ai nā kāleka Flash Monolithic a pehea e hoʻihoʻi ai nā Labs iā lākou¶

1. ** PCB maʻamau vs. Pūʻolo Monolithic:**
2. ** CFexpress Type B / XQD Kāleka a me nā Kāleka SD piha piha piha:** Loaʻa pinepine i kahi miniature internal Printed Circuit Board (PCB) me nā pahu flash BGA NAND discrete a me kahi puʻupuʻu kaʻawale kaʻawale (pinepine ka mea hoʻokele NVMe PCIe i loko o nā kāleka CFexpress). Inā hoʻoulu ka mana i kahi capacitor SMD liʻiliʻi a i ʻole TVS diode ma ka CFexpress PCB, hiki i kahi lab ke hoʻololi i ka mea i loko o 20 mau minuke a heluhelu i ka 100 pakeneka o kāu mau faila.
3. ** Nā Kāleka microSD āpau a me nā Kāleka SD Paʻakikī/Waterproof o kēia wā ("Monoliths"):** Ua hui pū ʻia ka mea hoʻoponopono, nā kaapuni, a me ka make silikon NAND maka i loko o kahi poloka paʻa o ka resin epoxy ʻeleʻele.
4. Pehea ka Monolithic Recovery Lab e hoʻopakele ai i kahi kāleka SD/microSD make:
5. ʻAʻole hiki iā ʻoe ke hoʻoponopono a 0 MB kāleka monolithic me ka lako polokalamu no ka mea, ua make ka lolo a i ʻole i laka ʻia e ka papa ʻōlelo unuhi firmware ʻino.
6. ʻO kahi keʻena hoʻōla uila kūikawā e waiho i ke kua o kāu microSD a i ʻole kāleka SD ma lalo o kahi stereomicroscope a hoʻomaʻemaʻe mālie i kahi lauoho lahilahi. 0.1 mm ka papa o ka pena ʻeleʻele ma ke kua o ke kāleka, e hōʻike ana i kahi hui huna o ke gula microscopic / copper diagnostic test pads.
7. Ke hoʻohana ʻana i kahi kiʻi spider multi-probe (PC-3000 Flash Spider Board a i ʻole micro-soldering 0.05 mm nā uea enamel i 20+ pads), ʻaʻole ka mea ʻenekinia i ka mea hoʻokele SD make a hoʻopili pololei i kahi loiloi loiloi i ka bus data flash NAND 8-bit (D0-D7, ALE, CLE, WE, RE, CE, R/B).
8. Hoʻokuʻu ka lab i nā ʻaoʻao NAND binary maka, hoʻohana i ka hāmeʻa ECC (Error-Correcting Code / LDPC), hoʻohuli i ke kumu hoʻohālikelike ʻikepili XOR o ka mea hoʻoponopono, a kūkulu hou i ka pākaukau poloka Flash Translation Layer (FTL) e hoʻopuka i kāu kumu kumu. .CR3 / .ARW / .MP4 waihona.
9. Kūkuai o ka Lab a me ka pale ʻana i nā hoʻopunipuni: ʻO ka hoʻihoʻi hou ʻana o ka monolithic NAND pinout pono e pono i nā lako waiwai nui a me ka mākaukau hoʻohuli hoʻihoʻi hohonu, ʻo ke kumu kūʻai maʻamau $300 a i $900 USD ma nā labs loea hoʻōla uila (ʻaʻole loa e lawe i kahi 0 MB Kāleka SD monolithic i kahi hale kūʻai hoʻoponopono kamepiula pahu nui, e hoʻopili wale ia i kahi mea heluhelu USB maʻamau, e holo i nā polokalamu mea kūʻai aku ʻaʻole i hana ʻole, a me ka pōʻino o ka make ʻana o ka silicon).

Ka papa helu hoʻopaʻa no ka male ʻana, ka hanana, a me nā mea paʻi kiʻi kahua¶

Ke hoʻoholo ʻia kāu pilikia o kēia manawa, e hoʻokō i kēia mau lula kahua ʻelima i hiki ʻole i kahi kāleka SD hoʻokahi ke hoʻoweliweli hou i kahi pana:

1. E pana mau i ka mea hou (Dual Slot RAW+RAW Backup) ma nā hanana koʻikoʻi: Inā ʻelua mau pahu kāleka kāu pahupaʻikiʻi, mai hoʻonohonoho pono iā lākou Overflow / Relay a i ʻole RAW to Slot 1 + Small JPEG to Slot 2 i ka wā male mare a i ʻole hanana uku. E hoʻonoho i ka pahupaʻikiʻi i Ka Hoʻopaʻa Hoʻopaʻa Hoʻopaʻa Hoʻokahi (RAW + RAW i ka Slot 1 a me ka Slot 2) no laila e kākau kēlā me kēia paʻi pani i kahi faila RAW like i nā kāleka kino ʻelua i ka manawa like.
2. **Hoʻopololei i nā Kāleka WALE I loko o ka pahupaʻikiʻi ma mua o kēlā me kēia pana ʻana (ʻaʻole e holoi i nā faila hoʻokahi ma ke kamepiula): ** Mai hoʻopili i kahi kāleka SD i kāu Mac a i ʻole Windows PC, e hōʻike i nā kiʻi o ka pule i hala, e kauo iā lākou i ka Trash/Recycle Bin, a hoʻihoʻi i ke kāleka i kāu pahupaʻikiʻi me ka ʻole o ka hoʻopono ʻana. ʻO ka holoi ʻana i nā faila ma ka lolouila e hoʻokaʻawale i ka exFAT cluster map a waiho i nā papa kuhikuhi ʻōpala OS huna ma ke kāleka, ʻo ia ka #1 hoʻomaka no ka pōʻino o ka waihona pahu pahu pahu pahu waena. Ma kahi, e hōʻoia ua kākoʻo ʻia kāu pana mua ma 3 mau wahi (e ʻike Kākoʻo kamepiula: 3-2-1 hoʻolālā a me ka hoʻōla pōʻino), a laila e hōʻano maʻemaʻe i ke kāleka i loko o ka papa kuhikuhi pahupaʻi ma mua o ka hoʻomaka ʻana i ka hanana hou.
