I had the exact same problem. The parameters in /etc/format.dat are wrong.
Replace the Maxtor entry with:

disk_type = "Maxtor XT-4380E" \
	: ctrl = MD21 \
	: ncyl = 1218 : acyl = 2 : pcyl = 1224 : nhead = 15 : nsect = 32 :
	: rpm = 3600 : bpt = 20940

partition = "Maxtor XT-4380E" \
	: disk = "Maxtor XT-4380E" : ctrl = MD21 \
	: a = 0, 14880 : b = 31, 29760 : c = 0, 584640 : g = 93, 540000

and this should work fine. You might want to extract the defect list first
and save it to a file. After you update the /etc/format.dat file, then
read in the defect list from the file (after you change the parameters,
the manufacturer's defect list is no longer readable.)
