Is smartctl kidding me ? Running the Brad Campbell's timeout script report all my Barracuda disks as good and all my WD as bad. > > > Cheers, > > Wol > > Kind, > Alexis Now my question are: Is it safe to assemble my array with my old drives ? Or do I need to replace my sdb (which reports a read failure and has been last updated on 2018-12-08) and/or my sde (which do not report any SMART failure, but a lower event count)? Is it safe to run my array in Read only mode for some weeks, waiting for new drives delivery (probably a 0.5TB or 1TB WD Red)? Which wiki page to follow: Replacing a failed drive, Assemble run or Recovering a damaged RAID? Kind regards, Alexis.
