I have a 2tb external drive that will only load as Read Only under Disk Management menu. It will load properly in another computer fine. I tried alot of things, uninstalled driver/reinstall, try change owner in security tab in properties, no option to switch to Online, has full control for everyone …

Passport External drive is read only

Try doing a search for Take Ownership and try that. Permissions/sharing on Vista and windows 7 can be a pain.
