July 19, 200916 yr Hello, I was wondering if someone has ran into this before. I am using the regular Unraid clearing for a hard drive I just added. It is a 1.5 Terrabyte Seagate. During the clearing stage I get 2 loud clicks about every 3-4 minutes. At first I thought the HD was bad, but it does it continuously and at certain intervals. Can someone confirm if this is common? Thank you
July 19, 200916 yr Clicking does not necessarily mean a bad drive. http://lime-technology.com/forum/index.php?topic=2664.msg33437#msg33437
July 19, 200916 yr Clicking does not necessarily mean a bad drive. http://lime-technology.com/forum/index.php?topic=2664.msg33437#msg33437 I disagree. but I am not prepared to argue the point. Bad cabling should NEVER cause clicking. But either way, I would yank the drive and beat the hell out of it (figuratively) in another machine before trusting any data to it.
July 19, 200916 yr A bad cable can cause commands sent from the controller to the drive to arive garbled. Garbled commands frequently look like seeks to disk locations that don't exist. These command (from what I've seen) cause the drives to make bad noises. These types of errors are relatively common here. I have personally had it happen two or three times. The smartctl logs show log entries of invalid commands, while unRAID is reporting disk errors. Fixing the cabling had eliminated these and restored proper functioning for me. I have never had a drive go bad and exhibit the "clicking" sound. Maybe I just don't know what it sounds like. But a bad cable definately can causes "bad sounds" from the disk that could easily be confused with clicking! (I agree that testing the heck out of a suspect drive is a good idea.)
July 19, 200916 yr Clicking in this context USUALLY means the drive is doing a re-cal, USUALLY because it lost its servo position... =BAD

As soon as possible, obtain a SMART report for the drive, and run the SMART long test. Please see the Troubleshooting page, Obtaining a SMART report section.
July 22, 200916 yr Author I replaced the sata cable and power cable and no more clicking. I've scanned my syslog and everything seems good and filled the drive with data. Thanks for all the advice!
