Got a smart warning today on one of my drives
SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed: read failure 90% 687 414069864
# 2 Short offline Completed: read failure 90% 687 414069864
SMART overall-health self-assessment test result: PASSED

The drive is under warranty, should i return the drive? or wouldnt this be covered under warranty?
Is this a serious error? seems to have prevented unraid from starting the array using this disk..

confusing it says read failure but also says the drive passed..
does that mean data is corrupted on this? and i need to swap it out and rebuild the array?

Get the data from this and then ask the shop. You can have a read error, the data gets relocated to a different part of the drive, and then it pass since the bad part of the drive is no longer used. The above program will tell you how bad the damage is.

As soon as you get any errors, back up the disk and replace the drive. You might want to not overwrite your last backups in case anything has corrupted.

Drives are cheap compared with data loss. If the disk is under warranty that's just a bonus.
