Hard drive failures are NOT always caused by circuit board failure.
Replacement the PCB will not solve the problem below:
1. The drive will power up normally (no ticking noises, errors etc) but will not be recognized by the computer;
2. The drive will power up normally and be recognized correctly but will report a size of 0 bytes;
3. The drive will power up but report SMART errors on boot;
If you want to search for a matching pcb, you can search on hdd zone. They sell pcb and can also help to find a matching pcb for your drive if you need do a pcb replacement.
no, it was same PC same hardware,
i was doing a virus scan then i was removing some found malicious content (pretty sure not on the drive in question since that only contained my own recordings and such) and after the reboot it kept restarting after the bios.
so i walked through the steps and unhooked my gpu, still rebooted after bios,
unhooked my other cards, still did it.
unhooked my 2nd hdd and it started up.
rehooked the 2nd hdd and it did it again..
unhooked it and it started up..
so i found that it was the drive...
