I have a Lacie mobile drive where the wire is connected via a mini usb and it was used with my old mbp firewire port - was it 400?

The two mbp's have different firewire ports.

I now have a jul 2009 mbp and i need an adaptor or a new cable to connect the two devices. So on one end the mini usb and the other a firewire to fit into my current mbp.

Can someone tell me clearly what i need to look for / ask for... prob look on ebay. Maybe a link to apple store so i can see exactly.

I hope it makes sense to someone. Thanks

Thanks for quick and comprehensive reply!

I googled and this is it

its a LaCie Mobile Drive 160Gb USB & Firewire. So it has a small connector on the drive and two wires - one for usb and the other for firewire.

The mobile drive has a mini b usb and a firewire 400 / 6 pin connector.

So i need Mini B to Firewire 800 9 Pin..... or firewire 400 6pin to 800 9pin... yes?

Mini B to Firewire 800 9 Pin.....
If you mean USB by Mini B, then use either a USB cable or a 6- to 9-pin Firewire cable. USB and FW don't work via one cable.
FW has its own chipset on the logic board, USB goes right through the CPU.

Either use USB cable like this:


or a FW 6- to 9-pin cable like this:



Deduced via the Manual of your drive: http://www.lacie.com/download/manual/p2_fw_hd_en.pdf

You have a MBP with a camera, you can always take a picture of the ports on the drive and post those.

Ooops, no need, mini B USB and 6-pin FW ports.

Just a note the FW-to-USB cables you see are generally only using the power pins to power/charge a device. They don't carry data.

good suggestion... although i think its all sorted.

i need this to connect to a jul 09 macbook pro - firewire 800 9-pin it seems.
You can also use a USB cable if you have one handy, the speed difference is marginal at best, especially since FW400 will get you similar speeds - I get 30-35MB/s via USB with an 2.5" 5400rpm drive.


All Intel Macs are able to boot via USB connected external drives, so FW is no need for this.

I knew you can boot from usb with intel however, when i tried to restore a superduper from the drive via usb the option on superduper didnt come up.

Maybe i didnt check it properly. Ill have another go later with the usb cable and see if i still need a new cable.

Thanks for all help.

I forgot i need to boot from the LaCie then the option to restore on to the Mac HD will become available - silly me.

Conserve USBs? Firewire 800 for Passport

I have a new MBP(newer than what I had) it is the solid block style, I had the old (2007 model)
Anyway all the usbs are on the same side and there are two of them. I like to keep iphone plugged in and my laptop try/fan also. heat killed my old battery)
PROBLEM
My Passport..uses the traditional mini usb-b to USB connector. I am looking at that firewire 800 socket and thinking can I purchase a mini b-----Firewire 800 and use it sucessfully?
Is such athing possible?

If you want a mini-USB to Firewire cable, then no. They are two different protocols and are not compatible.

You could get a passive (without AC) USB hub, I use one and my 2.5" HDD is even powered via that hub.

Hub-BUB

Regarding the hub suggestion...I have tried three different hubs. A GE, A Belkin and a ChinaHOCKEY...model. All of them drop signals. ie you start with say yer iphone and your just maybe your fan hooked up and then your external hard drive(passport) drops off..You get that nasty message abput properly exiting drives etc. I have tried all dif combos. I have never even used more than 2 ona 4X hub, and I still lose something. Sometimes ALL. Like I say I have tried three dif manufacturers, if you know of a better one, let me know.
