I converted my external hard drive named E: to NTFS. But why when I right-click on it, it still doesn't give me the options to click on "shrink volume" or "extend volume"? I am doing this in "Computer Management" >> "Disk Management" in Windows. My E: drive should be able to do this because it is now NTFS. Any suggestions or articles that might solve this problem?

Why do you want to shrink the partition? You can't shrink the partition because Windows does not support reading multiple partitions on external drives and therefore shrinking the partition to make room for another one is a useless operation.

    Windows seriously only allows one partition, even for a giant USB hard drive? Do you have a source link for that? Seems like a really, really terrible design decision... I've used USB drives with 2+ partitions in linux for years, actually I think I've used the same devices on windows too (had trouble getting win to read ext) – Xen2050 Mar 18 '17 at 20:35
  • @Xen2050 I think it's true, I have experienced it myself. See comments and answer here (not a source link, I know). I suppose it depends on the removable bit. There is at least one more amusing design decision: compare this and this. – Kamil Maciorowski Mar 18 '17 at 20:46
  • Simply not allowed in Windows, it doesn't have that capability. The only way to fix a drive which has multiple partitions on it is either 1. use another OS 2. use diskpart or 3. use 3rd party software.

  • "Simply not allowed in Windows." Nonsense! I have an external hard disk (a Western Digital My Passport) and Windows allows me to shrink its partition. – user477799 Mar 18 '17 at 20:52

    The total amount of space is the same. Splitting it into two pieces doesn't change the amount of space on the volume. – Aaron Franke Mar 19 '17 at 2:58
