Run enough disks long enough and you'll find one that starts returning garbage while telling the OS everything is ok. First time I had it happen was on a hardware raid device and a company lost 2 and a half days worth of data as any backups from when it started had bad data. The next time I had it happen is using ZFS and we saw a flood of checksum errors and replaced the disk. Even after that SMART thought it was perfectly fine and you could send commands to it, you just got garbage back. |
