Something odd is going on with my VHDXs. The OSs on two of them (Win7 | Win10) are reporting conflicting information regarding disk space usage, with the Win10 file system showing as wildly off (by > 100GB). Disk analysis utilities are reporting the smaller numbers, as does ChkDsk.

Win7 is a clean install, running for about a year now with no usage—it just sits there. It has absolutely nothing installed on it. Win10 runs SQL Server only.

Screen shots are below.

What do you make of it?

Win7, Computer report Win7, File system report Win7, ChkDsk report Win10, Computer report Win10, File system report Win10, ChkDsk report

  • @Goatmale: Thanks for the lead. I ran `vssadmin delete shadows /all` and was able to reclaim about 5GB on Win7. `vssadmin list shadows` on Win10 doesn't find anything. So I'm still not much further than before. – InteXX Nov 09 '16 at 08:39
  • Did you try checking for hidden / system files? On the C:\ drive the WINSXS folder is a killer. The NTFS MFT database, is perhaps large on the the D:\ drive. Page file as well. – Brett Larson Nov 09 '16 at 15:25
  • @Goatmale: I'll look at those when I get a chance and get back to you. May be a day or two. Thanks. – InteXX Nov 09 '16 at 21:31
