I have this 1TB Seagate Drive. I backed up my data and some of it was corrupt already so I lost some of it and then ran the preclear script to see if the drive is failing. I ran it the first time and there seems to be some strange numbers. I'm a little concerned about the "a change of -509 in the number of sectors pending re-allocation".
I have attached the results from the first run
After getting all of this not so happy result I decided to run the script again but this time with 3 cycles. I have attached the results from the second run.
I'm not quite sure how to understand these results. It seems like the drive is continuously having a different amounts of sectors pending reallocation yet it always ends with
During the preclear there were read errors that were displayed in syslog. Also, this drive was previously being used in a cheap external enclosure before being moved to my unRaid box.
Is this drive failling? Should I replace it? If so how can I tell based on the preclear results?
Thanks
