June 15, 20206 yr I installed a new 8TB drive on the weekend. I ran a preclear and the drive seem to pass successfully. Today I woke up an the drive has been disabled. Any thoughts would be apprieciated. Is this a possible bad cable? tower-diagnostics-20200615-0537.zip Edited June 15, 20206 yr by Gragorg
June 15, 20206 yr Community Expert Disk dropped offline so there's no SMART report, check/replace cables and post new diags.
June 15, 20206 yr Author I bought and installed a brand new sata cable but the drive did not come back online. What is the best way to proceed?
June 15, 20206 yr Author So I just rebooted that server. Was doing some searching and found this: Normally, you would replace the hard drive of a disabled disk; however, you can try to re-enable a disabled disk as follows: Stop the array. Power down the unit. Physically remove the failed disk, leaving the slot empty. Power up the unit. Start the array. Stop the array. Power down the unit. Re-install your failed disk. Power up the unit. Start the array. Is this the proper procedure I am supposed to follow after changing the cable?

Even simpler instead of physically removing and reinstalling the drive is: Stop the array Set the disk to Unassigned Start the array to make Unraid 'forget' the assignment Stop the array Assign the disk back to its slot Start the array

It seems to be rebuilding now. Would you mind taking a look at my diagnostics. There were two I'm not familar with "Seek Time performance" and "Throughput performance" .

June 15, 20206 yr Community Expert No idea what the meaning of those attributes is. Not something I have ever seen mentioned before
June 15, 20206 yr Author Just got 1 reallocated Sector count I assume this means the drive needs replacement?
June 15, 20206 yr Author Ok so the reallocated sectors just went up to 2. I am going to send the drive back and get a replacement. Should I let the rebuild carry on until the replacement gets here? Or stop it now? I dont really care about any data on it as it was only in for a day or two. I dont like leaving my array unprotected . Drive is upto 4 sectors now. Speed is 1.4MB/sec. Can I just cancel now and put replacement in tomorrow or new config and rebuild my parity? Edited June 15, 20206 yr by Gragorg
