Inside the PC HDD cages
Suspecting electric currents killed the HDDs when moving data?
External or internat?
If External, HDD drives usually won't last.
FYI for external HDD it is recommend to shutdown before disconnecting the drive.
Cuz Windows safely remove does not stop the drive so it is still spining.
Only if you shutdown than the HDD will stop spining than you can safely remove.
Like others mention it's best to move, if your intention is to savage those old drives.
No point seriously they are more than 10 years than HDD is slowly starting to die.
Just get it replace and move on.
