1、这是英文解答：
I was having a similar problem where After Effects, Premiere, and Sony Vegas could not create QT files on certain drives. After a lot of forum searching I finally found a solution thanks to a tip from Rob Maybury on CreativeCow.net
It looks like QT will only write to drives with a unique name. My volumes were set up as follows (looking at Windows File Explorer)
Local Disk (C:)
New Volume (F:)
New Volume (G:)
New Volume (H:)
I could create files in C: and F: but not in G: and H:. After changing the Volume names so they all were unique:
Local Disk (C:)
SSD Volume (F:)
Main Volume (G:)
New Volume (H:)
I could now create files on any drive.
To change the Volume name, right click on the drive and select 'rename' or bring up the properties window and rename it there.
2、大概翻译：在使用AE\PR\索尼VEGAS输出QuickTime文件时发生该错误提示，应该是计算机磁盘分区名称和前面的盘符重名。比如，你的C:（本地磁盘）、D:（新加卷）、E:（新加卷）、F:（新加卷），是可以在C盘和D盘输出，但不能再E盘和F盘输出，问题就出在这。D\E\F的盘符名称重复了，所以，修改你要输出盘符的名称，使其不与排在前面的分区重名。方法是在盘符点右键-重命名。
