Try the default username and password, of
and blank password ***** no password ***** no characters.
If that doesn't work, then locate the pinhole reset button, on the back side, or the underside, of the drive. Use the end of a straightened-out paperclip to press inside that pinhole, and hold down the reset button for 15 seconds.
Then after that, wait at least 2 minutes. Then after that interval, not before, try logging in to the admin web page with a username of
and no password ***** no-characters-in-password.
Let me know how that goes, please.
(Note: if there is data of yours on the hard drive, this might possibly make it impossible to access it, or wipe it... perhaps. So please proceed with that caution in mind, if you proceed at all.)
