Attn: All HD owners.....Hitachi and WD mostly. Seagate might work but not sure. Well for WD owners, it does seem the drives might have a way to force them to 1.5gbps. This COULD be the issue. We might need to force our drives back down to 1.5gbps to make them work again in our laptops. We have a jumper like all the WD drives do, that we need to insert into the correct spot to activate the 1.5 speeds. People with Hitachi's a person was successful doing this with a jumper on the drive and it worked. It allowed his laptop to behave normally again. See this as a explanation. http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1679&p_created=#jumper Going to try this tonight if I get time. Here is a good PDF from WD explaining the speeds. http://wdc.custhelp.com/cgi-bin/wdc..._tbl=9&p_id=1337&p_created=1126109811&p_olh=0 I am thinking that we got the update, and the update isn't allowing correct speeds with some drives at 3.0gbps. So we need to tell the drive to stop trying to use auto at 3.0gbps and force it back down to 1.5gbps. This might resolve our problems.
