This issue with Toshiba external drives has been brought up a few times here in this forum. It seems that it is always related to the power required for these particular drives. I wouldn't blame the MBA, as it seems that some Toshiba drives are really power hungry.


To use on the MBA, you need Toshiba's "Y-adapter" to span the power across two USB ports.

Additional information, in case anyone has a clue, the iMac and MacBook that it does work on were upgraded from Snow Leopard to Lion. The MBA was bought with Lion preinstalled so I don't know if a proper driver is missing from Lion that was available in Snow Leopard.

Update:


From System Information. Required power is 500mA, and I do believe the MBA can do 1000mA for the SuperDrive, so I doubt power is the issue. This information is available for a little while until the system gives up with "The IOUSBFamily was not able to enumerate a device."

I bought a Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive (HDTC610XK3B1) yesterday. I see a similar issue here:

1) Doesn't work with my MacBook Pro 17" (MacBookPro8,3) running Lion (10.7.2). I get the same error (26/11/11 1:00:16.000 AM kernel: USBF: 796.586 [0xffffff800c21a800] The IOUSBFamily was not able to enumerate a device.)

2) The drive works fine on an iMac and has been formatted as exFat on the iMac.


Both the MacBook Pro and iMac have been upgraded from Snow Leopard to Lion.

Any help is much appreciated.

I was working on mine again last night. My drive only works on Macs that were upgraded, I checked versions of the IUSBFamily.kext and saw differences. I am comparing them now. I am also going to swap the cable and see if that makes a difference.

Hello everyone (first post ever),


I have a similar problem. I bought a Toshiva Canvio 3.0 1Tb NTFS. My new MacBook Pro i7 doesn't recognised it. I use it in Windows and it worked well. I tried in an older MacBook Pro with SnowLeopard and it was recognised. Therefore, I use the utility disk of that computer to reformat it with HFS+. Then I connected it again with my computer and nothing happened. I tried in a computer similar to mine, and it didn't work also. I think the problem is within Lion.

Any idea will be great.

I also ran into the very same problem with a Toshiba Canvio 1TB USB3.0/2.0 drive. It works fine on a MacBook (late 2008) under Snow Leopard, but is not recognized on a MacBook Air (Mid-2011) under Lion. I have filed a bug report with Apple; I hope other people will do the same so that this might get fixed in the future.

I have a similar issue, but the Toshiba Canvio 1tb drive works fine on my MacBook Pro running lion, but not on my new MacBook Air. Another external drive with external power worked fine on the MacBook Air. An I bought the big external drive specifically for use with the MacBook Air. Crap!
