这个不是外接硬盘导致的，应该是某度的原因，你把文件保存位置改成电脑的下载应该也是错误17

并不是。本地硬盘没问题，外接硬盘报错17

/Applications/Motrix.app/Contents/Resources/engine/aria2.conf 修改里面的 file-allocation=none 记得重启Motrix

The external USB disk is probably using exFAT, a filesystem that doesn't support "preallocating disk space for files with the modern fallocate way". That is the root reason. And Motrix doesn't have an option in its UI to turn off the "preallocating disk space for files". But fortunately, it is configurable via the configuration file, as the example @LabEnbug presented. The configuration is actually for aria2, so besides none, you can also use prealloc and trunc, which represent filling the space with plain zero and using ftruncate respectively.

Preallocating is recommended for reducing fragment especially when downloading "Bittorrent" onto the FAT-family filesystem.
