For the last 2 years I have had the main Ubuntu OS running from a separate SSD, including swap. <br /><br />Assuming these rarely used drives have been idling in low power mode for the last 2 years I was very surprised to see:<br /><br /># for dev in /dev/sd[b-e]; do smartctl -a $dev | grep Load_Cyc | awk '{print $10}'; done;<br />2627999<br />2604655<br />2619279<br />2670247<br /><br />About 2.6 million cycles each, or 8.6 times their rating! I now have the RAID5 array backed-up to an external 3TB drive.Robhttps://www.blogger.com/profile/02559071992129052529noreply@blogger.comtag:blogger.com,1999:blog-2897594486266822320.post-15420973973948063092013-01-29T15:54:34.060-08:002013-01-29T15:54:34.060-08:00I would love to know were you stand at the moment ...I would love to know were you stand at the moment in the same place you are and have the drives on about 700k <br /><br />This also might help http://forums.storagereview.com/index.php/topic/29253-newer-western-digital-hdd-head-parking-and-you/Simonhttps://www.blogger.com/profile/05533865895917304298noreply@blogger.comtag:blogger.com,1999:blog-2897594486266822320.post-77726747457917472502011-12-04T12:34:01.543-08:002011-12-04T12:34:01.543-08:00I agree with Brian.

The drive is a WD 2.5" that I use in my linux router machine (runs 24hrs a day) and it has always made the bzzz-tick noise. I RMA'd the first drive to newegg right after I bought it because of the noise, when I got another drive that did the same thing I figured it was normal (but very annoying). This morning, using WDIdle3 I was able to disable the bzzz-tick; which is, apparently, the noise that the drive makes when it parks or unparks the heads (load_cycle). I used smartctl to check my load_cycle_count and it is almost 3 million! My drive was set up for load-cycle at 800ms, and it performed an average of 185 load-cycles an hour over the last ~2 years! :( Still it appears to still be working and, hopefully, it will continue to work.Greg G.https://www.blogger.com/profile/07766187992264421994noreply@blogger.comtag:blogger.com,1999:blog-2897594486266822320.post-1142870926192996262010-11-19T10:01:54.378-08:002010-11-19T10:01:54.378-08:00Great article, I was having the same problem.
