ok guys as per wht u all have recommended to use another molex connector with the sata power latching cable now my PC is continuesly working frm last 8 hrs without any problem
thnx to all the member who have helped me for Fault Localization :)…
but still my dvd rw is still not working n giving the power calibration error as i have told u before.
i am using a “SONY DVD RW AW G170A” which at present is only been able to burn and/or write 700mb normal CD.
And if some times by mistakes it detect the dvd , it shows that i have inserted a blank media.
i have implemented every maintainence task like cleaning of DVD RW lens with alcohol or distilled water .
i have also disabled IMAPI cd burning service as per the recommediation of the service manual.
Externel Conifiguration of DVD RW–>
Disk drive connector is a normal molex 4 pin connector
IDE data cable (as it is not a sata device)
but nothing is solving the problem …
any solutions ??
