[Re: preclear_disk.sh - a new utility to burn-in and pre-clear disks for quick add]

I just re-ran the preclear script on all 4 drives and sdb and sdc were successfully precleared.  But, sdd and sde this time froze at 88%.  This is interesting because when I ran the test on sde earlier, it did complete successfully.  However, I will rerun the tests on sdd and sde as JimmyJoe suggested to see what my results are.

 

Can someone help me interpret the SMART results from the two discs that successfully precleared?  Here are my results:

I've attached my syslog in case anyone needs it.

 

Thanks.

The script has frozen twice at 88% at the post-read progress.  The sdc drive has been at 88% for a few hours now and sdb drive did the same thing when I ran the preclear script on it 1-2 days ago.  Here is what I see in the telnet window right now:

Unfortunately, it doesn't proceed after this point.

 

BTW, I am using version .9.1 of the preclear script.

Hello!  I just got my new LC server from Tom!  Unfortunately, I am having problems with the preclear script.  I have 4 x 1TB Samsung F1 HD103UJ drives.  The parity disk (sdb) and Disk2 (sdc) both froze at 88% (Disk2 was done after a reboot of the server).  Disk3 (sde) reported the following SMART error differences:

Are all of these drives bad?

 

I've also attached my syslog.

 

Thanks.
