How do I go about shrinking a non-boot drive? I've read through all of the questions on here and can't find a thread similar to mine. I have a 931.51GB NTFS partition (D:/), and I'm trying to Shrink it using the Windows Disk Management tool.
So, first off, it tells me that I can shrink up to 154.027GB.
After I do this (I change the value to 100000 (100GB) instead, as that's what I want to shrink it by), I get an error after about 5 minutes:
I guess I'm just not sure what to do at this point. I have a lot of data on there that I'd really like to not have to delete, but if I have to, then I have to. I'm trying to dual-boot Windows and Ubuntu (or Mint) and the automated installer is failing to resize my partitions - I came on windows to try it here, and I have the same exact problem - there's definitely something going on here.
Here is a picture of my current Disk Manager display:
Things I've tried:
-chkdsk C: /f (found/fixed errors, still no luck)
-chkdsk D: /f (found/fixed errors, still no luck)
-WinDirStat to see if there are any weird files, and I did not see any ( but I don't know the tool that well)
I also noticed that Windows says that D is the "primary" drive, even though it's installed on my SSD (C:/).
I appreciate any and all feedback. If by some chance this question WAS posted elsewhere, I apologize in advance and I'll be happy to remove.
