Hello friends

I think It's complicated. this HDD when I scanned it with MHDD or Victoria it's

worked fine but I pressed ESC to stop the scan the drive power off then

recalibrate and detected. When I press F4 again and scan it's works normally

and so on. Is it ( head Parking ) or what ??????

Thank you all for any help

Check SMART parameters .

All SMART attributes are OK

Check if pcb is overheating or not .

Thank you rameez,

I already checked the PCB and you are right
