Ive recently added 2tb seagate to my array pre cleared it etc and recently noticed the load cycle count is high

 

my first drive problem with unraid what ya all think

Check the spindown delay and open it up.  I believe it defaults to 15 minutes, but the math shows the drive is spinning down around every 5 minutes.  Open it up to an hour or so if you want the load cycle count to slow.  The drive is rated for 300K cycles according to the Seagate datasheet.  That's about all I can offer without a syslog.

thanks for reply unevent ive got the drives set not to spin down, in the disk.cfg file all the attached drive have -1 entry next to each spindowndelay for each disc

 

Heres attached syslog hopefully you can see something i cant

 

Cheers

Could be APM on the drive itself causing the high cycle count since your log didn't show any spin downs, though the log was short.  Can use the hdparam utility to disable it - google it as it is probably covered here as well as with other NAS products using the newer greener drives.

 

ok will do thanks for help
