On my server I always leave them spinning, on my other computers I power down. It's really a double edge sword, as intial shock of start-up and loading to resting postion can indead flex the gimble assembly. Likewise, spinning constantly will produce heat which the metal of the suspension can warp as all metal does when heated. Had 3 harddrive failures over 15 years, 2 of which were 10k raptors (first versions) in which I had them foolishly stacked close together in harddrive cage.

I think the quality of harddrives and heat is the biggest reasons for harddrive failures. One of the reasons I use full size cases and clean out cases every 3 months with water free compressed air. Every manufactor has good designs and bad designs and basically come down to 3 types of failures.

1) circuit board on the drive fail
2) squealing...ball bearing issue where disk is not or can not maintain speed.
3) clicking...arm or read/write head failure.

20 years ago I started work for a company, Hutchinson Technology, in which I worked there for 10 years. In their prime, they did have 75% of the market in read/write suspensions. By no means am I an expert in harddrives, but do have a good knowledge base on the suspension part of the hardrives.

The role suspension I usually describe it as a needle on a record player. It doesn't come in contact with the disk itself but rather maintains a height above the disk called fly height. The flexure, where the head is mounted, is ultra thin, thinner than a human hair.
