** Description changed:

- jbd2 writes blocks to the hard disk every 5 seconds.  This makes an annoying click/tick noise and prevents the disk from spinning down to conserve power.  jbd2 appears in logs as several entries like...
-  Jul 19 21:35:45 edge kernel: [ 3312.913759] jbd2/sda5-8(350): WRITE block 42280704 on sda5 
- ... and can be observed using iotop. Since the noise only occurs in Ubuntu and not in Windows 7 it is probably a software problem.  The excessive writes may reduce the disk's lifespan.
