Hard drive renames itself
My hard drive keeps renaming itself for example this is what I had "Harddrive for mac" and now it's been renamed as "Harddrive for mac 1" .That wouldn't be so bad if the computer would let me change the name back. Every time I try to change the name back to "Harddrive for mac" the computer keeps renaming it as "Harddrive for mac "1". I go to the get info Side bar but every time I press enter it adds "1". Even if I don't press enter and I close the window for get info it's still named as "Harddrive for mac "1". I've tried other names and it doesn't add the extension "1" only on"Harddrive for mac" it that's the extension. And I have to keep the same name because there are programs that can't have their permissions changed(at least that's what they say). OH and the hard drive is an external hard drive via usb 3.0 and is from Western Digital (wd).So can someone please help me with this PLZ.
