Hopefully someone has experienced this and has a solution. I recently performed computer maintenance. It was a long time in between...5 months. It went well, except for the final step...defrag. Windows defragmenter would freeze my computer without completing the defrag. I tried Defraggler. Same thing. I tried Auslogics. Same thing. I get from 4-48% through before the computer freezes. Each freeze requires a hard reboot. 
Chkdsk shows nothing horrible and nothing to fix ("Windows has checked the file system and found no problems") There IS 12k in bad sectors. sfc /scannow shows some items that cannot be repaired, but the same can be said of my other 2 computers, and they still defrag. The defragmenters indicate that my hard drive health is good. HD Tune couldn't complete the long version, but the quick version turned up "all green". I tried disabling screensaver, antivirus, startup programs. I tried safe mode. All to no avail. I'm really stumped. The computer functions very well and I'd like to keep it that way.
Has anyone ever experienced this and managed to resolve it? Thanks for any insights...
