To know : What all things can I try myself to recover data? (Can I open the disk and do something myself with the hope of fixing? I know data recovery centers are possible, but they are very expensive.)
Disk : The disk inside Seagate 3 TB External (STBV3000100). I took out the disk and used as internal.
Issue : Hard disk not working.
Diagnosis so far :
Since this was supposed to be used as external disk, and I ran it almost 24*7 for a month or more, the motor has failed. I hear squeeky sound at boot up, as if the motor is not able to start rotation.
