j7n Posted January 17 Posted January 17 What are the chances of damaging a hard disk should it happen to lose power during an active writing process? I understand that at that point the heads are retracted in an emergency manner. Would the system be "smart" enough to cease writing before this happens? Perhaps I am thinking in a too analogue like fashion. But I am imagining how it still writes and corrupts data across the emergency trajectory. I happened to break a hard disk at a time which coincided with a loss of power, but I can't say for certain as it only showed a fault when some areas of it were accessed and I discovered it about a week later. It was one of those I mentioned on the leaderboard.

Which year? If it's not Seagate, which are born already damaged, I'd say Zero. It will use the remaining charge to park the heads immediately after it senses the power loss. 1

And I always advise to have a UPC. If not, wait at least 1min. to give caps the chance to discharge before turn on again. 1
