one of the drives in my microserver has just flagged up a smart warning for load cycle counts (320521 count). No other issues that are found.

Should I be worried enough to replace it know? its part of a mirrored drivepool so data loss is unlikely

It's not by chance a western digital drive? I wdidle3 flashed mine to prevent that issue, parking the heads every short interval (intellipark) saves power on desktops but is a killer for NAS drives.

By the way mine were western digital green 3tb drives, over 5 years no problem in RAID 5 open media vault NAS.
 
Nope, its a Seagate - can't even remember where it came from so its likely an old disk thats been through a few builds.

Edit - Just checked and its on the latest firmware, also passes the basic seatools test

In all honesty I haven't seen good quantitative data on the issue, other than manufacturers claims regarding mean time before failure for smart metrics.

Even on backblaze all I could find was user discussion around high values in short periods for western digitial drives

Cntrl F -> search for Load Cycle Count

beyond that there is this:
http://superuser.com/questions/197862/how-harmful-is-a-hard-disk-spin-cycle

which also suggests, no good data, I'd take a punt and keep it spinning if I didn't have lots to lose, let me know how it gets on.
 
Nothing to lose as its a mirrored drive so I guess I'll leave it for now.

I've run every basic test that seatools can do and its apparently ok.
