High i decided to buy an external hard drive for my laptop since the one that it came with its a 4200rpm hard drive. From what i have seen all external hard drives come with a 6 pin firewire conection or usb 2.0 but my laptop a dell inspiron 9300 has one of dose mini firewire conections. Should i get a 6 pin to 4 pin cable or one the other way around, or are they the same? Thanks for the reply. Here is the link to the cable and to the hard disk drive http://www.amazon.com/exec/obidos/tg/detail/-/B000067VB0/ref=ord_cart_shr/002-8110519-9525657?_encoding=UTF8&m=ATVPDKIKX0DER&v=glance http://www.amazon.com/exec/obidos/tg/detail/-/B0006GDC8K/002-8110519-9525657?_encoding=UTF8&v=glance Although the cable says it is a 4 to 6 pin connection on amazon, I checked iogear website and they have it published as a 6 to 4 pin cable.
