I just ran a 'badblocks' command over some of my old HGST 3TB platters I exchanged recently here overnight. It appears to me a drive just died tonight during the testing as it wrote an 11.6G output file of bad blocks and can't be accessed anymore.


I tested the drive on Thursday last week with smartctl without any errors and ZFS also did not complain about the drive. This happened to me for the first time and I'm curious if the 'badblocks' routine (destructive) is just so hard on hardware that an older platter can just die from it.

Do you experienced the same in the past or is this just a random event?
