A 30-second format seems too quick to be doing anything.
Since you have run a format, have you tried using the disk yet? Does it boot??
Maybe you can run one of the disk utility programs to see what the system says it is -heads/tracks/sectors, compare it to the specs on the Miniscribe & Seagate. Might help you decide what you can do then.
