TOPIC: Volume optimization fails after file optimization

Volume optimization fails after file optimization 06 May 2016 16:36 #7192

I have defragmented my files, but volume defragmentation has failed more than once. My MacBook Pro is running TT 8.0.3 with OS 10.12.4.

Any suggestions?

The usual reasons for failed optimizations are disk directory errors and unremapped bad blocks. Check the disk directory with the Volume Structures test or Disk Utiilty, and run the Surface Scan to check the drive for unremapped bad blocks.

If both tests pass, please send a message to This email address is being protected from spambots. You need JavaScript enabled to view it. , including a link to this thread. You will receive a reply be email. We may be able to tell from logs why the Volume Optimization is failing. Thank you.

If the internal drive is either a sold state drive or a hybrid, you should not run the optimizations on it. The makers of such drives recommend not optimizing them, because the drives firmware includes wear-leveling.
