Under the apple, about this Mac, more info, USB. See how much power is available and how much is being needed. Should be 500 available and less than 500 needed. Needed could be above 500 and it won't show above 500 unless it's an iPhone or iPad being connected. If it shows something like 400, lion probably does not have a driver. If its real low or at 500, it may be insuffient power. Your iMac can also be used to see how much power for comparison. If it's just power get a y connector so you can get power from 2 USB ports. Lion appears to control USB to tighter limits than snow leopard. Some toshiba drives have the same problem and they sell a y connector to solve the problem.
Thanks for the tips. I plugged it into the iMac, and checked what you said. It looks like the drive itself requires 400mA, so the MBP should have adequate power.
Is there a way to use an old Snow Leopard driver on Lion? The device clearly has SL drivers...I'm surprised they didn't carry over to Lion.
"Drivers" is a term that really makes no sense in the Mac world. Unless the product is unsupported by OSX (say a Blu-Ray Disc reader/writer or one of a billion different printers), a driver is unncessary. A USB hard drive is a USB hard drive, not requiring anything special except that it meets all basic standards of USB (2.0 or whatever).
So there's nothing to "use" from SL that will help you here. It is a plug and play drive from my review of the device.
I still think that there is either some sort of electrical issue with your MBP USB port or "I dont' know".
Apple still has a lot of work to do before I update to lion. This is just one of the problems. I don't know of a solution. If I needed a new computer at this time, I don't think I would buy an Apple computer because of all the problems. For the high price, you should get a problem free product or at least one that is easily fixable.
Major Lion Problems
Excessive Heat (all mpb have heat problems if you play games)
Auto graphic card switching hangs (with snow leopard blue screens)
Reading flash drives and external drives
Thanks, OrangeMarlin. Lots to learn about in land of the Macs.
Point taken on the driver. The reason I'm hesitant to assume it's power related is because everything else works. Here is a short list of other devices I've used it for in the week or so I've owned this machine:
- iPad (connected fine and charged iPad to full)
- Seagate GoFlex (connects fine, but this device also uses wall power)
- Samsung Spinpoint HDD (in an aluminum Rosewill enclosure, also uses wall power)
- iPod Classic (fifth gen, 30GB), also charges
- Samsung Captivate (Android phone), charges
I got this machine from the Apple store last week, when I swapped out my original purchase MBP due to a screen defect. I asked them to run a gamet of tests to ensure everything OK, and they complied (at least claimed to). I assume if I brought it back, with the drive, they would be able to test for a power issue, correct?
I have a brand new MBP with Lion. I have experienced none of your problems. No heat, even with powerful graphics programs. No Blue Screen. No problem reading flash drives. You're basing your complaints on your own person experience (a logical fallacy called confirmation bias), or on a self-selected group of individuals who come to this community discussion because they have an issue. The vast majority have no issues.

I have supplied feedback to apple 5 times over the last 3 months for the snow leopard blue screen graphic card switching problem. And I am not alone. Apple has made no attemp to acknowldge there is a problem. The heat and external drive lion problem is listed multiple times in the apple community along with the hang problem. I will be visiting the apple store shortly for the blue screen problem. Hopefully, not a wasted trip.
"Just a quick question, is it USB 3.0? There seems to be an issue with some USB 3.0 drives and the MacBook Pro."
Good question. The drive itself is capable of USB 3.0, but is backward compatible to USB 2.0, as well. For instance, my old ThinkPad T60p is only capable of USB 2.0, and is fully capable of reading this drive. But if I were to plug it into a USB 3.0 device, it should work there, as well.
The iMac is a few years old, and only capable of USB 2.0, and it can successfully read this external, as well.
I should have thought to list that in the original description - thanks for thinking of it. That being said, given that all these older machines can read the drive without incident, do you think it likely that 3.0 is the culprit?
This worked for me when I had a similar issue with my LaCie drive:
Open Disk utility (/Applications/Utilities/) and see if your hard drive shows up on the side.
Also open Apple System Profiler (Apple menu>About this Mac>more info) and see if your hard drive show up there under 'usb'.
If they show up in either of those places, it implies that the problem may be with mounting. You may have accidently turned off mounting hard drive on the desktop. Try turning it back on:
Finder>Preferences>Sidebar>tick hard drives.
