I have a real crappy no name external drive (actual brand is iogear) and I have major problems trying to transfer over anything bigger than 300 megs using firewire. The drive will shut off half way thru the transfer and then I get an windows error message that says delayed/fail write. And I can't access the drive again until I restart my computer. I ran norton disk doctor and the only error I see is in the security descriptors. The error message says "The second NTFS boot sector is unwriteable" Now what does that mean?? When I use the connector for USB 2.0 I don't seem to get any delayed fail write errors, but the computer won't shut down or start up if I have the external drive connected using USB2.0. But if I have it connected to my laptop using USB1 , I don't have problems. So i'm thinking there is a setting on my desktop Bios that I have to turn on or disable. I just don't know what it is. MOBO is an Asus p4c800-e deluxe.
