Drive pulsing after completely filled
« on: February 04, 2012, 05:15:31 PM »
I was downloading some media to one of my drives (formatted in standard format), and after moving / deleting space from the drive it seems to be making a pulsing sound like a motor or helicopter.  I tried doing a reboot in the menu which seemed to help, but I see that it's returned.  I now have about 300 GB free on the drive, but it constantly seems to be making the pulsing sound.  Has anyone else encountered this?

I'm not sure if it was the fact that the drive was completely full which triggered this, but I don't recall the sound occuring before.  Very odd!  Functionality seems normal, but I'm worried that the extra thrashing (of the head?) will prematurely kill the drive off.

I've never encountered quite what you have described but I did have a drive that started 'clicking'.  I reformatted that drive and ran SMART tests which showed that the reallocated sector count had changed.  I assume there were bad sectors that the formatting changed with spare sectors.

Maybe you have the same and the drive is telling you to make a full backup and reformat.
