Hello, I've a hard drive with corrupt blocks. I would like to know if those blocks belong to a real file. /var/log/message reads: smartd[1306]: Device: /dev/ada3, 3 Currently unreadable (pending) sectors devices ada2 and ada3 are in ZRAID1 mirror. zpool scrub won't show any error. smartctl full test find errors: SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error ../.. # 2 Extended offline Completed: read failure 80% 33003 460087328 ../.. # 5 Extended offline Completed: read failure 90% 32936 460087313 I've made some attempts with zdb -R to read faulted sectors, but I keep receiving errors like these ones: Invalid block specifier: gpt/ben: 460087328:512 - offset must be a multiple of sector size Invalid block specifier: gpt/ben:409600000:512 - size must be a multiple of sector size whatever offset and size I try (4096/512), I always receive one of these errors... Any idea? thanks, Pat
