Yog tias koj qhib lub faulty hard disk, tshem lub taub hau thiab siv lub zog rau lub cuab yeej, lub cav ua haujlwm nrawm, tab sis tom qab ib pliag nws nres. Nws yuav siv me ntsis tweaking kom nws tau kiv mus txuas ntxiv thaum lub hwj chim nyob.
Cov Lus Qhia
Kauj ruam 1
Disconnect hauv hard drive.
Kauj ruam 2
Nrhiav ntawm cov tsav tsav lub microcircuit uas tswj lub cev muaj zog (ncaj qha lossis dhau cov yuam sij transistor).
Kauj ruam 3
Siv lub khob tsom iav thiab lub teeb nyem, sau cov cim rau ntawm lub microcircuit no kom raug.
Kauj ruam 4
Nkag mus rau txoj hlua txuas hauv qab no hauv cov lus tshawb xyuas: chipname datasheet, qhov twg chipname yog hom ntawm tus nti.
Kauj ruam 5
Saib hauv lub datasheet nti rau qhov chaw nyob tus pin hu ua SPNENAB, spindle enable, lossis zoo sib xws.
Kauj Ruam 6
Ua tib zoo (tej zaum yuav tsum tau me me soldering hlau, tweezers, tsau thiab tsom iav) muab txiav cov hluav taws xob sib txuas ntawm tus pin IC los ntawm lub rooj tsav xwm hauv Circuit Court.
Kauj Ruam 7
Siv 1 kilo-ohm resistor. Ntawm nyias cov kab hluav taws xob (thiaj li tsis ua rau lub rooj tsav xwm puas thiab microcircuit), txuas rau cov hluav taws xob tso tawm los ntawm cov kab hluav taws xob no nrog lub zog +5 V.
Kauj ruam 8
Muab lub zog rau lub hard drive li qub. Nco ntsoov tias lub cav tsis nres lawm, txawm hais tias koj cia nws ua kaum tsib feeb lossis ntev dua.
Kauj Ruam 9
Yog tias koj yuav tsum tau qhib lub hard drive motor cais los ntawm nws rooj plaub, tshem lub rooj tsavxwm, lub cev muaj zog thiab cov disks. Nws tuaj yeem siv lub zog xoob cov screws kom ruaj khov rau lub cev muaj zog. Unsolder qhov txuas txuas lub rooj tsavxwm mus rau lub cev muaj zog, tom qab ntawd hloov nws nrog txheej txheej ntawm qhov xaim zoo nkauj. Tawm daim ntawv xov hluav taws xob zoo li nws yog thaum siv lub duav rov qab. Mount lub cev muaj zog thiab tswj hwm hauv txhua txoj kev koj nyiam. Yog tias koj xav tau lub zog hluav taws xob hauv Circuit Court nrog ib qho hluav taws xob ntawm 12 V, txais tus thib ob sib npaug rau 5 V los ntawm nws, siv 7805 tus kws tsav tsheb rau lub rhaub hluav taws xob thiab ntxiv nrog thaiv capacitors.
Kauj ruam 10
Thaum koj tau txais lub cev muaj zog kiv yam tsis muaj nres, tuaj nrog txoj hauv kev siv nws. Muaj cov lus piav qhia ntawm ntau yam khoom siv hauv Is Taws Nem siv cov motors xws li: cov cuab yeej hluav taws xob qis, hluav taws xob hauv tshuab hluav taws xob siv cov cwj pwm stroboscopic, thiab lwm yam.
