Joe Bloggs Posted May 24, 2019 Share Posted May 24, 2019 Hmm... any idea why this may be happening? C drive is my system drive, is a spinning rust drive, etc. Link to comment Share on other sites More sharing options...
trium Posted May 24, 2019 Share Posted May 24, 2019 what do you mean with your question? can you not start windows defragmenter and instead defraggler started? have you another hdd drive/partition and this can also not defragmented with windows defrag? perhaps you have defraggler set as default defrag - in this case make this: defraggler -> settings -> options -> advanced -> untick replace windows disk defragmenter Versions of CCleaner Cloud; Introduction Ccleaner Cloud; Ccleaner-->System-Requirements; Ccleaner FAQ´s; Ccleaner builds; Scheduling Ccleaner Free Es ist möglich, keine Fehler zu machen und dennoch zu verlieren.

Joe Bloggs Posted May 24, 2019 Author Share Posted May 24, 2019 No, I explicitly did not tick that option when installing. I can launch the default windows defragmenter just fine--it just doesn't show the C: drive as an option. Link to comment Share on other sites More sharing options...
trium Posted May 25, 2019 Share Posted May 25, 2019 perhaps try this: open your windows-explorer -> with your mouse on your c-drive click right -> kontextmenue -> properties -> tools -> optimize Versions of CCleaner Cloud; Introduction Ccleaner Cloud; Ccleaner-->System-Requirements; Ccleaner FAQ´s; Ccleaner builds; Scheduling Ccleaner Free Es ist möglich, keine Fehler zu machen und dennoch zu verlieren.

Moderators Nergal Posted May 25, 2019 Moderators Share Posted May 25, 2019 Let's start with some information that will help troubleshoot. What version of windows? What version number of defraggler, and from where did you download it? When you ran defraggler I assume you used it to defrag the c drive, did it finish the job? or did it error out? Can you still defrag the drive in defraggler? ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

Joe Bloggs Posted May 25, 2019 Author Share Posted May 25, 2019 1. Windows 10 2. Defraggler free downloaded from CCleaner.com 3. It started off at 10% fragmentation, I noticed that C drive is missing from the system defragmenter while it's running. I Stopped the defrag when it was down to 1% fragmentation (reckoning it's good enough and wanting to see if that brings C back into the list on the system defragmenter) but C remains missing there. I've tried rebooting and also clicking into defragment from C drive's context menu. 4. Yes, I can still use defraggler on C Thank you in advance Link to comment Share on other sites More sharing options...
