What do i do? is the drive bad? thanks

  • Author

i checked the logs folder but its not there and i have since rebooted the system and the logs are new now and  the old one didn't save. I can do another parity check if that will help get the logs again. I have that one 3tb drive that red balled but looks ok maybe i replace this drive with that and do a preclear on it?

Has the replacement drive been pre-cleared (for testing)?

  • Author

its this drive that red balled  http://lime-technology.com/forum/index.php?topic=33070.0

 

i pre cleared it and looks ok i think i will remove disc5 and put this in and let it rebuild and do a parity test then pre clear disk5 and see if its okay. Is that a good idea?

 

this is the 3tb drive from that link

Very similar situation tom mine here http://lime-technology.com/forum/index.php?topic=33016.0

 

Interestingly, my "problems" are also with WD30EZRX drives.

 

Wonder if there's a possible kernel <-> drive "glitch".

 

yea that's weird but from my drive it looks like it red balled because of the UDMA_CRC_Error_Count  something to do with the cables i re pluged it took out disk 5 and i rebuild the data, right now i am waiting for parity verify then i will preclear disk5 to see why its making those errors.

  • Author

okay it finally finished pre clearing disc5 some things that changed

Offline_Uncorrectable used to be 1 and is 0 now

Raw_Read_Error_Rate was 33 is now 46

 

here is the result from pre clear

is that what is causing the errors to show next to the drive? Raw_Read_Error_Rate and Seek_Error_Rate and how come Unraid doesn't care it cant read a sector?

 

Apr 26 08:03:53 Tower kernel: md: disk5 read error, sector=5826013640

 

or is it trying to read it fails and then tries again and succeed so it shows up as a error but it doesn't red ball it>?

 

what do you think is the drive okay to use?
