OTOH that the drive was opened one time, does not make it insignificantly risky to open it a second time. Opening the hard disk much likely was a big mistake. [1] I only would risk it a second time, if anything else doesn't help. 2 Cents, Ralf [1] Begin forwarded message: Date: Mon, 18 Sep 2017 00:07:01 +0000 From: MAILER-DAEMON@yahoo.com Subject: Failure Notice Sorry, we were unable to deliver your message to the following address.

However, if my drives fail with this click-click noise and something should be missing by the backups, I demount the drives, but let them connected to the PSU and mobo, then I hit the drives from all directions with increasing force, from soft with the hand to not that soft with a stick, not necessarily while lying flat on a table. .
