Does anyone know if my mac does not had enough power for this drive if it is possible to use an external power supply for the second input instead of using 2 outputs from my computer?

If you hook the the additional USB to a power source, I don't see why it wouldn't work. Just make sure the additional power only cable is the one you hook to power only.

Logically "yes" if it supplies 5V and at least 500 mha per USB specifications. Look at the power source.

I bought this drive for my macbook pro. I only plug in one of the usb inputs into the computer and it runs fine.

You don't have to use both of the USB ports, I only use the one. The thought is the secondond USB cable will increase the speed but honestly I haven't noticed any marked increase

While I used it without the power adapter temporarily, I would recommend plugging this in. It will give you better longevity of the device, and it won't use extra power from your computer. I am not entirely sure whether you have external drives is a factor. I assume you are talking about external HDD or DVD drives?

I had the same problem with both of the ones that I bought. One of them doesn't even work as a thumb drive. I am not sure if this is a POS, or maybe they don't work with Mac?

I'm sorry not to be able to answer you. My Iomega eGo Mac crashed before I could find out. It went Kaput. I bought a Seagate.

I have this unit daisy chained to 2 thunderbolt drives from my mbp. Love the seagate unit though I have heard that constant switching of ssd units takes a toll in the ssd connectors. I should think you could daisy chain a monitor through something like a black magic mini recorder which I also love or... Get a thunderbolt hub. Jim gurney

Are you sure that you used the USB cable correctly? You need to plug both USB cables to your computer for the drive to work. One would only provide power, and the other would be used to transfer DATA, neither one can work on its own. As a troubleshooting step, try to use a drive in the enclosure that you know for sure is not dead, if that one works, and the other one is still giving you problems, then it might be a problem in the drive itself but not the enclosure. However, if the drive that you know is working well, still doesn't show up on the computer, then it might be a problem in the enclosure. Hope this helps!

You should probably find out if you have a USB 3.0 port on your machine or plan on getting a docking station in case your Macbook doesn't recognize this external drive.Personally, I have it working on a Toshiba laptop using W8.1 without any problems (read/write DVD single and dual layers + read/write Blu Rays) however it needs at least two USB ports to get enough power to function (I'm using 1 usb 3.0 port and 1 usb 2.0 port) so make sure you have enough available ports to power this.

Yeah, you do. I got a sata to 4 pin adapter for the power since my Mac Pro doesn't have any extra power ports. I'd check out the cal digit options. Their a little more expensive but don't require extra power. I've read mostly positive reviews of them. Again I'm on a Mac so there isn't as much support for USB 3 in older machines

Yes I'm running two hard drives. If you want more it would have to be an external.

No. It requires external power for the drives and most other USB-powered devices. I ended up connecting my non-powered USB devices into the hub and those requiring power directly into my iMac. Fortunately, I had sufficient devices that didn't need power that it worked.

You need to plug both USB ends. This way, your external HDD will draw more power than from a single USB 2.0 port.

It seems clear that this unit does not come with a power supply, but seems to have a standard barrel connector to accept an optional power supply. To use small external (2.5") drives I need to have an external power supply. Can someone post a link to a power supply that will supply at least 2 amps and is compatible with this 4-port Sabrent hub?

There's not enough power (amps) through USB, it needs to be a self powered drive but yes it can hook up to the USB.Also must be formatted in FAT32.

No, it's intended as a desktop drive, meaning the external power supply is needed. But it's worth checking out LaCie's portable HDs. I have a 250GB Porsche-designed one that's been a workhorse for years.

i have the power plugged in with 7 drives. I think the reason my drives didnt work is because there's not enough power on the bus for drives. I know you can run one drive without a problem, but don't know about 2. I would assume you want power just so you don't loose the drive in the middle of writing as happened to me before without this hub.

I have used ONLY Mac's for many years; but they can be expensive to fix from time to time. I do have the round power plug. Thank you for you input.

I would say no since the latest drives I could find were for Power PC. It looks to be pretty dated drivers for the Mac.
