Use "hdparm -i" to check the UDMA mode, "*" marks the one selected by
the BIOS (udma2=Ultra 33, udma3=Ultra 66). Make sure that udma3 is only
selected if (1) your motherboard supports it and (2) you have the right
cable. If this is the problem then check if Seagate has a Utility to
disable the Ultra 66 mode.

Does this help?
