Hi;
So I have a zfs mirror of 2 identical drive WD Red 3TB and smartctl complain about having a bad sector on one.
After few months and backups, I decided to replace both drive with newer driver and take the opportunity to scan them with badblocks
the command I used is
after 3 days of checking for bad blocks the result for both drive is (0/0/0 errors)
So I plugged them into my TrueNas SCALE just to test and the smartctl complain about bad sector again.
What is similar on these servers ?
- Both machine are using Debian
- Both drive as been plugged with the same SATA Cable (I ordered new cable, they are on their way)
What is different on the testing machine (badblocks) ?
- I used a docking station
My 2 questions are:
- Could a bad cable make smartctl complain about bad sector ?
- What other tools would you recommend ?
