External HDD use under OS14
I recently shifted from a macbookpro OS12.5 to a macbookair OS14.6. I have 2 external HDD both of which are in the WD Elements series. One is in the Extended Journal format and one in the APFS format. Under OS 12.5, I used to copy files and folders from my laptop into the external HDDs directly, and move files and folders around within those HDD freely. Now, under OS14.6, when I want to copy a file or folder into one of those HDDs, I must enter my mac password, and if I want to move files within those HDD (for instance combine a number of files into one folder) not only do I need to enter my mac password but the files are not "moved" they are "copied." So, if I need to combine 3 folders that are 1GB each into a new folder, the system tries to copy 3GB of data.
Any idea what has changed between OS12 and OS14 to cause this to happen?
