Hard Disk Hacks
« on: April 26, 2008, 01:42:16 PM »
.. nakuha ko 'to dati sa tipidpc nung nakipag-swap ako sa isang member..
 defective pala 'to.. ma-bad karma ka sana!  di ka pa nagpakita uli.. hmmp! >:(

on the positive side, meron akong pwedeng pag-experimentuhan..  ;D


first question sa mga nakapag-try na, paano ba paikutin yung disk? ???
ito yung rear view nya, three terminals sya:


saka yung slider (yung kinakabitan ng read/write head) paano pagagalawin ? ???
ano pa kaya ang pwedeng gawin dito?

complicated nga pala talaga syang paikutin..

Brushless, sensorless motors with three connections are in
fact, not DC motors at all. They are actually permanent
magnet synchronous AC, 3-phase motors.
The commutation is done electronically. Three distinct
semi sinusoidal waveforms (not pure sinewave AC) that come in
at different times (or degrees) will causes the rotor to
rotate with the changing (alternating) magnetic fields of
the stator.

mahihirapan akong gumawa ng DIY circuit nito using mga discrete components..  :'(

Mababasa pa kaya yun kahit maasemble? Pero naalala ko dati sa CSi, nung sinunog ng kriminal yung PC (at bahay ata) narecover pa din yung data kahit sira na at ndi na nabasa yung HDD. Galing...  :D

TV show kasi, kaya baka hindi naman totoo.. hehe  ;D

pero sa tipidpc may mga bumibili pa ng mga sirang harddisk (40GB and above)..
ewan ko kung narerepair pa nila, and then ibebenta uli..
pinapalitan lang siguro yung disk..

yung iba kaya binibili para mabenta pa sa marerecover. yung Prof ko dati ginagawa yun. ;D

pwede pa ulit mabasa pag nare-assemble na. may mga modders kasi na ginagawa clear acrylic or polyurethane yung case ng HDD para nakikita yung pag-ikot. hindi lang advisable for novice modders.

back to topic:
di ba yung mga 12V fan na gaya ng nasa baba ay brushless din?

3-phase din kaya sila?  ???
ano kaya kung kunin ko na lang yung controller and then ikabit ko dun sa motor ng hard disk?  ::)

brushless din sila pero 2 phase lang. baka pwede adapt, hindi ko lang alam kung anong part number nung IC. pero common ang controller ng mga Fan na nabaklas ko. matibay din yung IC kahit Overvoltage na at 20V hindi pa rin bumibigay. ;D

di ko masyadong ma-gets yung pag-plot nito Hard Drive Laser Oscilloscope
yung "voice" coil sya yung para sa Y-axis(amplitude), eh ano naman yung nagko-control ng X-axis (time) ? ???
