I've made a clean re-install of Windows 8.1 x64 today. I decided to check the disk defragmentation schedule. To my surprise, dfrgui.exe did not list drive C:, showing only my external hard drive (drive D:). It shows this:

Funny thing is, if I plug the external HDD out, dfrgui doesn't start. At all.

I've seen a similar issue discussed here, however, in that case, the asker's problem was resolved by repairing some corrupted files, which SFC /SCANNOW doesn't find on my computer.

What could be the problem with dfrgui? And what can I do to fix it?

  • have you tried some other program that does the samething as this tool? – Ramhound Mar 25 '15 at 11:46
  • Is your C drive an SSD or a spinning hard drive? – ChrisInEdmonton Mar 25 '15 at 11:46
  • @ChrisInEdmonton: regular HDD, not an SSD. – Mints97 Mar 25 '15 at 12:03
  • @Ramhound: no, not yet... can you recommend any good ones? – Mints97 Mar 25 '15 at 12:04
  • @Mints97 - No; There are hundreds of tools; You should pick one yourself. – Ramhound Mar 25 '15 at 12:06
