    OT: External USB/Firewire harddisk needs power supply?

    I just ordered an external 250 GB Iomega HDD USB2 and Firefire compatible for use with my laptop to store the samples and song projects -

    But I see a power cable listed in the parts shipped. Does the harddisk need a power supply or can it draw power from USB/Firewire? If it cant run without a power supply it wont useful in a flight etc at all. I cant find this info anywhere.

    You must use the Power Adapter. I assume that a 250GB hard drive just consumes too much power to be supported via a USB or FW power connection.

    Here is the info at Iomega's website:

    P.S. - I see that some of their SMALLER GB drives don't need an adapter. For example, their 60GB drive states "no AC adapter needed":

    Thanks.

    But that is so tiresome.. I have a portable laptop and controller but need a power cable just for the harddisk. Ive already ordered it.. Do any of you use an external harddisk greater than 120 GB that does not require a power cable?

    I'd check www.cnet.com for reviews of hard drives, it's a very useful site. I see for example that SmartDisk has some small bus-powered firewire drives, but only till 80gb.

    Consider, however, that your notebooks battery will be running much shorter when you use a bus-powered hardrive ánd a bus-powered controller.

    I'm afraid the market isn't really there yet for what you want. (Mabye I'm wrong, I don't know all there is out there.)

    I'd consider having lite-versions of sample programs on the internal notebook drive and use that while traveling. Then fine-tune the results later with the full samples using the external drive.

    For example, the 4 layer-white key version of Scarbee Rhodes is about 400mb (I guess) instead of 2.25gb. And it still plays very Rhodes like.

    Yeah thats what I have done. Put the ones I use frequently on the notebook harddisk (which is 5400 rpm) and the bulk of the samples on the external. I just dont like the idea of an extra power cable when Im working on the notebook, even at home.

    You can't get away from the fact that devices need power. The more "powerful" they are, usually the more power they need.

    I would suggest contacting the company from which you ordered your drive, and see if they will accept a return, or exchange with one of the "no power adapter required" models.

    Unfortunately where I live, there's no return policy. Anyway I wanted an external backup device for my Desktop, so I would have kept it in either case. I'll get a separate portable device for the laptop later, till then I'll make use of this.
