If this occurs, you should consider moving the data and replacing the disk.ĭo not use a block-level copy to transfer the data. If the number of bad clusters detected by dynamic bad-cluster remapping is too high, you cannot shrink the partition. For example, if the unmovable file is the paging file, you can use Control Panel to move it to another disk, shrink the volume, and then move the page file back to the disk. In some cases, you can relocate the file temporarily. When you provide the querycluster parameter, the command output will identify the unmovable file that is preventing the shrink operation from succeeding. If you know the cluster or clusters associated with the file that is preventing the shrink operation, you can also use the fsutil command at a command prompt (type fsutil volume querycluster /? for usage). If the shrink operation fails, check the Application Log for Event 259, which will identify the unmovable file. When you shrink a partition, certain files (for example, the paging file or the shadow copy storage area) cannot be automatically relocated and you cannot decrease the allocated space beyond the point where the unmovable files are located. You cannot shrink the volume beyond the point where any unmovable files are located. The key point is this part of the info message you posted:

Tip: If your volume is not a System one you may wish to skip the initial steps (before Restart) The first time I tried to resize it the minimum size was around 425GB. I used this method to successfully shrink a System volume (C:) on Windows Server 2012R2 from 500GB (with only 50GB of actual data) to 80GB.

The interesting fact which often goes unsaid is that after a partition shrink the minimum size is also reduced (of course, if you have free space, defragged, no unmovable files, etc). I have later found similar instructions at other places, all of them mentioning only these 3 items. If Disk Management complains that “There is not enough space available on the disk(s) to complete this operation.” even though you entered a size that should work according to Disk Management's own figures, see Cannot shrink C: partition: Not enough space Reduce partition size, and then restore the three items. Now the three files that were preventing partition reduction are gone. In the “System Properties” dialog as above, go to the “System Protection” tab, click “Configure.” and select “Disable system protection”. Click “Advanced System Settings”, then in the “System Properties” dialog's “Advanced” tab, open the “Performance” settings, go to the “Advanced” tab, click “Change.” under “Virtual memory”, untick “Automatically manage paging file size for all drives”, select the drive you want to shrink, select “No paging file” and click the “Set” button. Open the System page in Control Panel (from “This PC”/“My computer”, open the Properties). Running under Windows 10, but I doubt it makes a difference here.Īt a an elevated (admin) command prompt, run the command powercfg /h off I have followed the instructions here, and I successfully shrank my OS partition in about 10 minutes.

There seems to be absolutely no need for any third party software.
