1.5TB Bus-Powered Drive

Hi. This is not strictly a MacBook Pro question, but perhaps someone can help. I am looking for a 1.5TB bus-powered drive that I can connect via FireWire 800 to my MacBook Pro. Seagate appears to make one called the FreeAgent GoFlex Ultra–portable drive. Two questions:
1. Has anyone used this drive with a MacBook Pro? Any concerns about the drive being able to pull enough power thru the bus-powered connection?
2. I plan to put my 1.1TB iTunes library on the drive. Has anyone encountered difficultes with iTunes on a FireWire-connected drive?
Thank you!

I moved my iTunes library onto a FW-800 attached drive many months ago. It works great. I will warn you that if you start iTunes without the external drive attached, iTunes won't complain, it will just start using your internal/primary drive as if that was where things were supposed to be. Personally, I would rather it give me an error about not being able to access my library, rather than just silently using it's defaults and letting me think it's using the external drive.
Just so that we don't feel "cheated", my wife runs a similar configuration, but under Windows, and her config does exactly the same thing. She has had times when we lost power during the day and when the power was restored, the external drive did not auto power-on. She returned home and didn't realize this and ran iTunes assuming it was updating her external drive, but it wasn't...

  • Bus powered external hard drives and the Powerbook G4 17 inch

    Does anyone have a suggestion for a bus powered external hard drive that will work with the Powerbook 17 inch? I had purchased a Simpletech Simpledrive portable USB 100GB bus powered drive and it will not work with my 17 inch. It works with my 15 inch titanium and a G5 but not the 17 inch. Simpletech told me that it isn't getting enough power from the USB ports (I even tried using the adapter to plug it into both ports at the same time).
    I am going to return the drive and probably buy a Firewire one instead since you can boot from Firewire but I am wondering if I will have the same problem with Firewire on the 17 inch and HAVE to use an AC adapter.
    PowerBook G4 17 inch   Mac OS X (10.4.1)  

    This also happens on the PB 15". It is perceived as a problem. If you check via the System Profiler you will likely see that the USB port output is 500mA. Most drives - in a USB or FW case - need 1A to boot. There are some drives that will boot with 500mA. If a 500mA drive is installed in the USB case it should boot off the bus power. If using a ext HD you can only boot the computer from the FW port and not the USB or PCMCIA slot.
    The FW port will power the ext HD. I do not recommend daisy chaining unless you use a powered FW hub. I blew 4 FW ports and had to replace the logic board 4 times but Apple Care paid for all the work. The newer FW ports are more robust but it is still a chance if you try to draw too much power.

  • Bus Powered External Firewire (800) Drives and iPod?

    I bought a WD Passport drive, and was pretty upset when i found out that the usb ports on my powerbook cannot power the drive. crap. can the firewire 800 port on my powerbook power these drives:

    I really want a bus powered drive. does anyone know if these will work with my 15" powerbook? one better than the other? oh, and i'm getting it to keep my itunes library on...so will my powerbook have any problem with reading the fw800 drive and the ipod in the fw400 port at the same time?

    Well the second linked drive says it is bus powered and does not require a external power brick. Usually most of external 2.5 inch notebook drives (in a 2.5 enclosure) can be bus powered. The 3.5 inch ones are generally not bus powered.

  • Bus powered external drive

    I want to buy a small portable external HD (USB2 or Firewire) for my MBP; of course, the bus powered ones have the advantage of being totally portable/free of wires, but I'm wondering if either USB2 or Firewire ports on my MBP would supply enough power? Or would it drain the battery too fast? I plan to at least put the LiveType and Soundtrack files on it and have FCE use it as a scratch disk.
    Would a bus powered one do or should I go for one with an adapter?

    I've looked at the Seagate portable drives again - none of them seem to have an external power source option.
    If you read the "3.5-inch External Data Sheet", you will see that they come with a power supply (under Package Contains, on the second page). What they don't seem to have, is a bus power option. It's not mentioned anywhere.
    Actually, I've never heard of any bus-powered 3.5" hard drive. I don't think the FireWire bus could power even an economical 3.5" drive, and USB 2.0 (even with double USB connection) is probably way too weak either. AFAIK, every bus-powered drives that exist are 2.5" or smaller (sometimes, a combination of two 2.5" drives can be powered by FireWire).

  • How many bus-powered usb external drives per hub?

    I'd like to have two bus-powered USB hard drives (to be used as backups with Time Machine) connected to one powered USB hub. Would that work, or would a powered hub be likely to support only one bus-powered external hard disk? (In that case I could get a self-powered hard drive for my second backup drive.)
    Thank you.

    Likewise it your needing another External Hard Drive, I would recommend spending a little more for a more rugged Desktop drive to use for storage or backup.
    Go with an OWC Mercury Elite Pro or a LaCie Little Big Disk and stay away from those cheap-o WD MyBooks.

  • Bus powered external Firewire drives

    Most portable external drives are now bus powered, many don't even have a power input.
    I wonder how many bus powered Firewire driives I can daisy-chain. Where should I place them, at the beginnig, in the middle, or the end of the daisy chain.
    I have several powered Firewire drives including my Time Machine Drive.

    Use a powered Firewire/USB hub so there is enough power to power the port powered devices.
    What happened is port powered devices are cheaper and many people opt for the lower price than the ones with their own power supplies, so it creates a problem and computer makers had to turn off ports drawing too much power from the comptuer, so people have to run out and get powered hubs.

  • Bus powered external drive for MacBook

    Hi,
    I'm looking for an external HD to use with my MacBook, and I'm a bit confused about power. I'd rather avoid lugging around an extra power supply and international adaptor when I'm traveling if it can be avoided.
    Does the MacBook's firewire port provide bus power? Is it sufficient to power a 2.5" external HD?
    Is USB a better option if I want a bus powered HD? Are there any clear advantages to one or the other?

    For the longest time, FireWire was the only practical solution to bus-powered hard drives. FireWire provides a heck of a lot of power (typically 7 to 8W) while USB by definition provides up to 2.5W per port (if powered). FireWire has so many advantages, but cost seems to be the consideration that's won out.
    Current USB bus-powered external drives seem to be feasible because of newer 2.5" drives with reduced power consumption. Still - many drives come with (or they can be bought) cables with two male ends. One end is used for data/power, while the other draws more power from a 2nd powered USB port.
    I have no problem getting a 160 GB WD Passport (Black) USB 2.0 drive to work on my iBook 1.42 or my new MacBook. It does take a while to mount in the OS though, although the same goes for Windows.

  • What's the largest capacity bus-powered external hard drive?

    I realize that this isn't a Mac specific question, but I'd really like a recommendation. What's the largest capacity bus-powered (preferably USB) external hard drive available. My new MBP has a 500GB drive so I would need something with probably 640GB or bigger. Problem is I can't find anything over 500GB that's bus-powered. Everything I've found requires an external power supply which is what I'm trying to avoid. If anyone has a recommendation, please share it.

    Have a search on the web for USA retailers who supply empty enclosures and drives separately. The enclosure is the physical case and the bits of circuitry and the physical ports. Tell them what you want and ask him what drives and enclosures he has to suit your purpose and if he can fit the two together for you. I have such a supplier but am in UK.
    Does it have to be a USB bus? Firewire is better and gives more power. One way I power a 360GB pocket drive is to feed from TWO USB ports on the computer into one input port on the drive(now in the enclosure) you should be able to buy a sort of "Y" shaped cable with two full size flat USB connectors at one end and one single connector at the drive end. The drive end often will be a mini usb port. What you want will depend upon the size of the input into the drive.

  • Bus Powered external fw 800 Drive

    Hi! I am going sttrongly concidering buying a Lacie 250GB bus-powered Firewire 800 Hard drive. I know it is bus powered but I can not seem to find out how much energy that it uses to spin up. Would my 15" macbook pro be able to support it through the firewire 800 port while on battery? I am going to buy this drive to acompany Aperture 2 so I can have a good, fast drive to store my files on when I am on the road. This hard drive is found at http://www.lacie.com/products/product.htm?pid=10949.
    Thank You.

    Hi - I have used the Lacie Little Big drives and they are great. I use the 7200 rpm as it's for video and they also have two FW800 ports allowing you to attach as many as you like in a series. It also has a FW400 port for attaching other deivces.
    They also make a Rugged drive that is bus powered but this only has one FW800 port so you would need to swap if media was on several drives for video editing etc.
    Cheers

  • Possible? FW400,160GB Hard drive. Bus powered?

    I need an INEXPENSIVE external bus-powered (FW400) mobile hard drive, 160GB. I want to be able to edit video & have it bootable.
    Any thoughts? I narrowed it down to 3 drives:
    1) OWC Mercury On-The-Go 160GB FW400. $139
    2) Lacie Rugged All terrain 160GB
    3) Smartdisk Firelite 160GB

    Tell me about it! Aren't they great?
    That's what keeps me from getting one too. The price. I mean, you can even build your own for less.
    Go to places like Newegg.com or DealMac.com (where they list daily, all the lowest prices for different Mac-related things) and you can get a good hard drive then buy your own enclosure.
    Won't look like the G-Raid mini, but does the job.
    Again, I recommend SmartDisk, but your decision is the final one. =)

    I seem to keep doing this on most of posts... (forgetting the last thought).
    Did you try the Western Digital brand ones? They're not bad either. I just don't like the way they look. That odd off-angle enclosure like they were made wrong. They're popular too.

    By the way, Seagate has them as well. Though their designs are even worse! Plus Maxtor.

  • Editing with Bus-powered External Drive

    Hello,
    I have a MBP and usually edit using a bus-powered USB drive. It works fine, but I'm wondering if I would get a performance increase if I use a bus-powered Firewire drive. I know Firewire is faster, but if the drive is a 2.5-inch 5400 RPM that's powered by the Firewire port, does it matter?
    Thanks.

    Yes, FireWire is indeed faster than USB. FW400 is about 40% faster and FW800 about 70% faster for typical throughput. This will be true regardless of hard drive (assuming the same hard drive in any case.)

  • Bus Powered External Hard Drive?

    Can anyone recommend a good bus-powered External Hard Drive that I can use with my iMac? I really like Western Digital's MyBooks, but they require mains power and come with a big power brick, which is pretty messy. I want a hard drive that gets it's power through either USB 2.0 or Firewire. And I'd like something that has at least 250GB of storage. Any suggestions?

    I bought a bus powered OWC laptop drive (100GB 720RPM) for around 170 dollars. But, that was for my laptop, as it's much easier to have a bus powered laptop drive then needing to plug it in to use it. This way I can sit somewhere, not near a power outlet, and be able to use the drive.
    As mentioned in an earlier post, 3.5 Hard Drives require to much power in order to be bus powered.
    You could buy a 200GB hard drive, bus powered, 4200RPM, and is a laptop drive for your iMac, but that's not the best way to go. First, the drive is going to be very expensive. You could get a 320GB 3.5 In HD for way cheaper. Second, it's going to be noticibly slower.
    When I get externals, I buy the drive, and pitch in 50 bucks or so for an external enclosure. It's the CompUSA brand and they work quite well. They are not bus powered, but the Power Brick is limited in size and is relitively small. It's cheaper this way. This can be a challenge to someone who isn't really 'computer-talented.'
    I'd go FireWire....It's much faster and won't slow you down while you're trying to access your files and do your work.
    OWC if you really want that bus powered laptop drive.
    NewEgg if you want to shop for drives, and get them cheaper. Not to mention their fast shipping.
    Give it some thought.

  • Bus powered USB drive

    I have an early 2011 MBP and would like to put a large USB drive on it that's bus powered. My recollection from earlier times was that USB drives required two ports, one for the data and one for the power. Is that still the case, or can current USB 2.0 drives carry data and power the drive on the same port?
    Thanks very much.
    All the best,
    Tom

    Tom,
    Current drives either get all their power from one usb port or if they require more current then the usb provides, they have their own power supply that plugs into the wall.

  • Bus powered FW hard drive

    Hi everyone,
    I'm looking for a bus powered FW hard drive for about $150. I'll be using it as my secondary scratch disk while traveling. Any suggestions would be great!
    I'm currently using a UBS bus powered Western Digital drive; No problems yet with as a scratch disk, but i don't want to press my luck!

    if the drive has its own firewire controller and serial converter built in (some do), then it should work but of course with a lot of latency.
    but other drives with a firewire port do not have an onboard controller and rely on "daisy chaining" for the firewire port to be active.
    only one way to find out though, aside from reading its packaging materials.

  • Can I Use Bus-Powered USB Drive

    Hi.
    I have a La Cie ("All Terrain") USB hard drive that I normally connect directly to my G5 Quad's USB ports. It draws its power off the bus.
    However, I'd like to use it with my Airport Extreme as a network-shared drive. Does anyone know with certainty whether the AE can supply the necessary power to the USB drive, or will I have to get a separate Transformer/Adapter for this USB drive. Also, am I taking any chances on harming the AE if I give it a try?

    I have a WD Passport 250GB USB powered drive that works fine. I use it to stream video to my iMac. I also have a WD MyBook 1TB w/ external power that works fine for storage but is too slow for streaming.
