| Dhismaha Hard Disk-ga[You must be registered and logged in to see this image.]
Sawir muujinaya qaybaha Hard Disk-ga[You must be registered and logged in to see this link.] waxaan kaga hadalnay guud ahaan waxa uu Hard Disk-gu
yahay iyo qaybaha uu ka kooban yahay. Qaybahaas waxaan sheegnay
inaan ka soo qaadan doonno kuwa ugu muhiimsan oo ah kuwa sawirka
kore ka muuqda ee ay nambarradu ku ag qoran yihiin. Waxaan ka soo
hadalnay qaybta 1-aad oo ah Platters-ka, casharkaanna waxaan kaga
hadli doonna inta ka hartay qaybahaas innagoo u soo qaadan doonna
sida ay nambar ahaan u soo kala horreeyaan.Qaybaha aan halkaan ku soo qaadan doono waxay
kala yihiin: (fiiri sawirka qaybaha ay nambarradu ku ag qoran
yihiin):
- Heads
- Spindle
- Actuator
- Interface connector
- Power connector
- Heads (Read/Write)
Heads-ku waa qaybta wax ku qorta waxna ka
soo akhrisa [You must be registered and logged in to see this link.] Hard Disk-ga. Sidaa darteed ayaa waxaa loo yaqaanaa
oo ay caan ku yihiin magaca Read/Write Heads. Dhinac kasta oo
ka mid ah labada dhinac ee Platter-ka waxa ku dul rakiban hal
Head oo u qaybsan inuu wax ku qoro waxna ka soo akhriyo
dhinacaas. Tusaale ahaan haddii uu Hard Disk-gu leeyahay
saddex Platters, wuxuu markaa yeelanayaa lix Heads oo mid
kastaa uu wax ku qoro waxna ka soo akhriyo mid ka mid ah
lixda dhinac ee saddexdaas Platters-ka. Heads-ku waxay qaab
ahaan u eg yihiin isku sina u shaqeeyaan saxanka
jiiro-digsiga (stereo) madaxa ku dul rakiban ee ka akhriya
soona saara wixii cod ah ee ku duuban. Platters-ku waxay u
wareegaan sida saxanka jiiro-digsiga in kastoo ay ku socdaan
xawaare aad u dheereeya. Platter kastaa wuxuu ku wareegaa
inta i dhexaysa labada Head ee kor iyo hoos uga rakiban.
Halka ay Platters-ku ka wareegaan Heads-ku waxay u socdaan
midig ama bidix si ay marba u tagaan [You must be registered and logged in to see this link.] iyo [You must be registered and logged in to see this link.] markaas la rabo
in wax laga soo akhriyo ama wax lagu qoro (fiiri sawirka
kore).

Sawir aad loo weyneeyay oo muujinaya laba Head oo laga
dhex saaray Platter-kii u dhexeeyey
Heads-ku waxay ka mid yihiin qaybaha Hard
Disk-ga ugu muhiimsan uguna qaalisan xagga samaynta, waxayna
door weyn ka cayaaraan xawaaraha iyo tayada hawlqabadka guud
ee Hard Disk-ga. Xawaaraha uu Hard Disk-gu akhbaar ku soo
akhriyo ama uu ku kaydiyo wuxuu si toos ah ugu xiran yahay
xawaaraha ay Heads-ku wax ku qoraan waxna ku soo akhriyaan.
Marka uu Hard Disk-gu dansan yahay ama uu
fadhiyo oo uusan wax shaqo ah haynin Head kastaa wuxuu dul
saaran yahay oo uu ku dhaggan yahay oogada (seface)
Platter-ka uu ku dul rakiban yahay. Laakiin marka uu Hard
Disk-gu kaco si uu hawl u qabto Heads-ku in yar ayay kor u
kacaan oo oogada Platter-ka ma taabtaan. Waayo haddii ay
Heads-ku taabtaan oogada Platter-ka iyadoo uu Hard Disk-gu
shaqaynayo waxay taasi keeni kartaa in uu dhaawac gaaro
Platter-ka ama Heads-ka laftooda ama labadaba. Taasoo keeni
karta in Hard Disk-gu uu guud ahaanba kharribmo halkaasna ay
ku lumaan wax kasta oo ku kaydsanaa. Sida keliya ee hadday
taasi dhacdo looga soo kaban karo waa inuu jiro koobi
(Backup) aad horay akhbaarta uga samaysay oo ama Diskette ama
Hard Disk kale ku kaydsan. Waayo Hard Disk-gaasi waa ku
daayay oo isaga iyo wixii ku kaydsanaaba waa tuuris. Haddii
uu Hard Disk-gaasi ahaa midka kaliya ee uu Kumbiyuutarkaagu
lahaa, markaa waxaad ku khasban tahay inaad Hard Disk cusub
soo gadato, haddii kale kuuma suurtoobayso inaad
kumbiyuutarka isticmaasho. Dhaawaca noocaan ah waxaa keeni
kara dhawr arrimood oo ay ka mid yihiin:
- Iyadoo si uun uu qashin u galo inta u
dhaxaysa Heads-ka iyo Platters-ka inkastoo maanta ay
adag tahay in ay taasi dhacdo oo shirkadaha Hard
Disk-yada sameeyaa ay aad uga taxadaraan.
- Iyadoo kumbiyuutarka oo shidan ay
gaarto jug keenta in Heads-ku ay gariiraan ama ay
qalloocdaan oo ay markaa taabtaan islamarkaana xoqaan
oogada Platters-ka.
Sidaa darteed aad ayay muhiim u tahay in
aadan kumbiyuutarka xoog u dhaqdhaqaajinin isagoo shidan.
Haddaad isagoo dansan qaadaysana aad si taxadar leh u qaaddaa
si uusan kaaga fakan waayo taasi waxay keeni kartaa in
Heads-ku ay qalloocsamaan oo marka dambe ee kumbiyuutarka la
shido ay xoqaan Platters-ka. Arrintaan waxay si gaar ah
muhiim ugu tahay kumbiyuutarrada yar yar ee gacanta lagu
qaato (Portable Combuters) oo iyagu si fudud kaaga dhici
kara. Waxaa kale oo iyaduna aad muhiim u ah in inta uu Hard
Disk-gu caafimaad qabo aad had iyo jeer koobi (Backup) ka
samaysatid akhbaarta muhiimka ah ee kumbiyuutarka kuugu jirta
si aad ugu baxsato marka ay baahideedu timaaddo. </li> Spindle
Spindle-ku waa matoorka wareejiya ee ay
Platters-ku ku dul rakiban yihiin (fiiri sawirka kore ee
muujinaaya qaybaha Hard Disk-ga). Spindle-ku wuxuu, sida
sawirka kaaga muuqata, tiir dhexaad u yahay oo uu isku hayaa
dhammaan Platters-ka Hard Disk-ga, wuxuuna Platters-ka ku
wareejiyaa xawaare aad u dheereeya si uu ula shaqeeyo ulana
qabsado xawaaraha Heads-ka. Sidaa darteed xawaaraha
Spindle-ku wuxuu muhiim u yahay xaawaaraha hawlqabadka guud
ee Hard Disk-ga.
Actuator
Heads-ka Hard Disk-gu waxay fiidda hore uga
rakiban yihiin gacmo dhaadheer oo loo yaqaan Head Arms.
Gacmahaasi waxay iyaguna ku sii rakiban yihiin oo isku haya
qaybta loo yaqaan Actuator (fiiri sawirka kore ee
muujinaaya qaybaha Hard Disk-ga). Actuator-ka shaqadiisu
waa inuu isku mar dhaqaajiyo gacmaha ay Heads-ku ku rakiban
yihiin si ay Heads-ku hadba u tagaan [You must be registered and logged in to see this link.] iyo [You must be registered and logged in to see this link.] ay akhbaarta
markaas loo baahan yahay ku kaydsan tahay. Sida aan hore u
soo sheegnay xawaaraha ay Heads-ku wax ku soo akhriyaan ama
wax ku qoraan wuxuu aad muhiim ugu yahay xawaaraha
hawlqabadka guud ee Hard Disk-ga. Laakiin Heads-ku iskood uma
dhaqaaqaan ee waxaa dhaqaajiya Actuator-ka. Sidaa darteed
xawaaraha Heads-ku wuxuu si toos ah ugu xiran yahay xawaaraha
Actuator-ka. Taasina waxay Actuator-ka ka dhigaysaa qayb kale
oo iyaduna aad muhiim ugu ah xawaaraha howlqabadka guud ee
Hard Disk-ga.
Interface connector
Interface Connector-ku waa halka ay Hard
Disk-ga kaga xiranto fiilada isku xirta ee akhbaarta u kala
gudbisa Hard Disk-ga iyo kumbiyuutarka intiisa kale (fiiri
sawirka kore ee muujinaya qaybaha Hard Disk-ga).
Fiiladaasi waa fiilo ballaran oo u eg sidii suunka dhexda
lagu xirto waxayna u muuqataa sida aad ka arki karto sawirka
hoose.
[You must be registered and logged in to see this image.]
Fiilada akhbaarta u kala gudbisa Hard Disk-ga
kumbiyuutarka oo uu nooceedu yahay IDE
Sida sawirka kaaga muuqata fiiladaasi waxay
dhinaca ku leedahay diillin guduudan (cas). Diillintaasi
waxay muujinaysaa dhinaca ay fiiladu Hard Disk-ga u galayso.
Inkastoo Hard Disk-yada casriga ah ay fiiladaasi hal dhinac
oo kaliya u gali karto haddana waxaa jiray xilli ay labada
dhinacba u gali jirtay oo ay aad u sahlanayd in si khaldan
loo galiyo. Sidaa darteed diillintaas waxaa loogu tala galay
in looga hor tago khaladkaas. Marka fiilada si sax ah loo
galiyo Hard Disk-ga waxay diillintaasi maraysaa dhinaca xiga
Power Connector-ka oo ah halka uu Hard Disk-gu korontada ka
qaato. Interface Connectors-ku waxay u kala baxaan laba nooc
oo kala ah IDE iyo SCSI. Labadaas nooc iyo wax ay ku kala
duwan yihiin waxaan ku soo qaadan doonnaa casharkeenna kan
xiga.
Power connector
Sida aan horay u soo sheegnay Power
connector-ku waa halka uu Hard Disk-gu korontada ka qaato (fiiri
sawirka kore ee muujinaya qaybaha Hard Disk-ga). Sida
kaaga muuqata sawirka uu casharkani ku billawdo Power
Connector-ku wuxuu leeyahay afar ilig oo fiilada korontada
waddaa ay ku xaranto. Fiilada Hard Disk-ga korontada siisaa
waxay iyaduna leedahay afar duleel oo ay afarta ilig ee Power
Connector-ku kala galaan, sida kaaga muuqata sawirka hoose.
[You must be registered and logged in to see this image.]
Fiiladaas dhinaceeda kore ee halka af leh
wuxuu ku xirmaa kumbiyuutarka qaybta ugu qaabilsan qaybinta
korontada ee la yiraahdo Power Supply. Dhinaca hoose ee
labada af leh wuxuu afkiiba ku xirmaa Hard Disk-ga, CDROM-ka
iwm. Taasoo uu micneheedu yahay in Hard Disk-gu uu ku xirmo
mid ka mid ah labda af ee dhinaca hoose. Labada af waa isku
mid oo kii lagu xiraaba wuu ku shaqaynayaa. Fiiladaan waxaad
iyadana aragtaa inay leedahay dhinac guduudan (cas).
Dhinacaas waxaa isagana loogu tala galay in looga hor tago
khaladkii aan kor ku soo sheegnay. Laakiin Hard Disk-yada
maanta la isticmaalo hal dhinac oo kaliya ayay fiiladaasi u
gali kartaa oo maba dhici karto in si khaladan loo galiyo.
Casharkaanna halkaas ayaan ku joojinaynaa.
Casharka xiga waxaan hadduu rabbi idmo ku soo qaadan doonnaa
xawaaraha Hard Disk-ga.
