February 20, 20206 yr Fix Common Problems is reporting "disk6 (WDC_WD30EFRX-68EUZN0_WD-WCC4N1JPZL86) has read errors" The main page tells me there are 16 errors. Unraid has not disabled the disk. I have run an extended SMART self-test from within Unraid and it outputs "Completed without error" How do I resolve the error?
February 20, 20206 yr Post diagnostics before you reboot. Read errors mean that the system couldn't read from the disk, then recalculated what it was supposed to be and wrote the data back to the disk. If that write failed, then the disk would have been disabled.
February 20, 20206 yr Author The disk isnt disabled. I would have thought that if there was a problem with the drive the SMART test would have identified them. So I was surprised to see the test report that it was completed with no errors tower-diagnostics-20200220-1326.zip
February 20, 20206 yr 100% the drive had a read error.. But it appears to have rewritten to the same sectors no problem, with out having to reallocate a spare From the SMART report rror 1 [0] occurred at disk power-on lifetime: 32365 hours (1348 days + 13 hours) When the command that caused the error occurred, the device was active or idle. After command completion occurred, registers were: ER -- ST COUNT LBA_48 LH LM LL DV DC -- -- -- == -- == == == -- -- -- -- -- 40 -- 51 00 00 00 01 16 e5 1b 60 40 00 Error: UNC at LBA = 0x116e51b60 = 4679080800 I'd keep an eye on it, but don't worry excessively right now.
