How long are Seagate's replacement times? very fast, IME. I've owned lots of Seagate drives, and have had to send exactly one in for replacement. I had the replacement drive within the same week. You can even get them to send out a replacement drive *before* you send the bad one back to them, if you don't mind them charging and crediting your credit card once they receive the bad drive. -- Send responses to the relevant news group rather than email to me.

Have you tried other Firewire cables? -- Send responses to the relevant news group rather than email to me. E-mail sent to this address may be devoured by my very hungry SPAM filter.

A FW400 plug is metal and long and securely fits into the jack; similarly a USB plug also securely fits. A FW800 plug is short and wide and plastic and the design lacks retention. It should go back to the drawing board. -- m-m http://www.mhmyers.com

Nope, it aught to be so, but it isn't. The USB is still running through both CPU and mobo and depending on the mobo+CPU calls. There are a few - very few - computers that have independant and fully balanced USB connections, but Mac is not one of them. You can 'fool' an USB port to believe that it is balanced by using an external fully balanced USB hub with separate PSU. - Imaging said you could also say it so that USB is a 'serial construction', while Firewire is a 'parallel construction'...
