Maxtor's stock has not traded in that range since June 2004. Maxtor shares soared 45 percent, or $2.04, to $6.56 on the New York Stock Exchange. Seagate shares eased 1 percent, or 23 cents, to $19.37, also on NYSE. Seagate's Chief Financial Officer Charles Pope said on a conference call that the deal would not close until the last half of 2006, given that it may take some time for an antitrust review with regulators.
